Highly Accurate Lift and Duration! This will make a serious increase in performance.Dell bios bin file
Install instant oil pressure in your Shovelhead engine. Replace the stock Harley oil pressure relief spring.Which system is used depends on three factors: 1. Speed of rotation or oscillation. Operating temperatures 3. Whether heat has to be removed from the area of lubrication.
If a function of the lubrication is to control or cool friction-generated heat, then preference will be given to oil, which can flow away, dissipating heat while recirculated oil is introduced to induce relative coolness.
Grease is used when the bearing operates under normal speed and temperature conditions. An advantage is that it is cheaper—although cost should not be a concern on a motorcycle like Harley Davidson, where a need for quality should dominate price. More important advantages over oil is that grease offers better adhesion and provides protection against dampness and external impurities. A word of caution, though…since the best quality grease is designed to fight water as in condensation or normal rain, not the nozzle of a high-pressure jet hose that riders love to direct at vulnerable weeping wheel seals.
Oil is used when the speed of rotation and temperatures are extreme, like inside an air-cooled engine like Harley Davidson.
The 8 Most Common Harley-Davidson Problems & How to Handle Them
More is Mandatory A second trait of Harley riders is that bigger is better or more is mandatory. This gluttonous attitude is reflected in too-big cams that produce less power, bigger carburetors that deliver too much gas and louder exhausts as in drag pipes that decrease horsepower. With lubrication, riders love to overdo their perception of quality. Two examples are: 1 The almost religious use of weight oils by pre-Evo riders.
There is no known use for wt. I explain this ad infinitum to customers in my store, but it remains a best seller.
Its use just makes the owner feel better and feeling good is what it is all about. So what happens? On initial takeoff the bearing rollers must accelerate too rapidly under load and, instead of rolling or turning, they slide. As they slide, they cut through the all-important lubricating film that separates roller and mating race; now we have metal against metal, causing hidden damage.
Synthetic grease is better and use it if you like, although the reader should realize that its primary advantage is low frictional resistance at low temperatures down to 0 C. If you ride in that kind of weather you are a better person than I. Before using miracle lubes that allow your engine to run without oil for 13 years remember the example of skidding as opposed to rolling rollers. Is the miracle lube designed for an air-cooled engine that uses the types of bearings in your bike and the types of metals that rub against each other?
Well, well. In fairness, some of these coatings do work. For example, Harley has started using black Teflon coating from the rings down on Sportster pistons to assist in break in and will expand this use to Big Twins in Also new are bottom end roller cages having a slippery copper like substance on them for the same purpose. More on synthetics later, but before merrily using them, be aware there are five kinds: diesters; silicones; fluorinated; polyglycols and syn-hydrocarbons.
Sorry for laying the big words on you. I did this just to point out that there is a lot to learn before experimenting. I sometimes think that scientests invent these brain twisters just to keep their domain exclusive to them and to confuse us. Which synthetic is best for your Harley? As a generalization, choose a 20W50 name brand detergent synthetic that is designed for an air-cooled engine.
Use synthetics only after the engine has been broken in. Break ins require fossil oils.I have a Ultra Classic.Character feelings lesson plan
The motor was suppose to been rebuilt a couple of years ago but I do not have proof of that. The bike shows 54, miles on it. My question has to do with the Harley oil pressure. When I first start the engine up my oil gauge shows 30 psi. Once it is warmed up and under load it shows 20 psi. At idle it shows 0 psi. Is this something I should be worried about or is it normal for a Twin Cam If you could shed any light on this matter I would greatly appreciate it.

Adding an oil cooler or a fan is always beneficial. Depending on the climate where you ride, a cooler may be important to add.Harley-Davidson motorcycle engines are air-cooled, which sets them apart from many water-cooled engines.
Air-cooled engines run warm and therefore require a higher viscosity thicker motor oil. Harley-Davidson has made nine different types of engines, starting in Each Harley-Davidson model may have a different oil recommendation, and other variables exist: "Refer to your Harley-Davidson owner's manual for the proper SAE grade recommendation based on the climate and temperature range you ride in," according to the Harley-Davidson official website.
Harley-Davidson recommends the use of its own Harley-Davidson H-D motorcycle oil, made of 75 percent premium mineral oil and 25 percent performance additives. The SAE 20W50 oil covers the biggest range of operating temperatures and is ideally used in ambient temperatures ranging from 60 to 80 degree Fahrenheit. Harley-Davidson classifies this oil viscosity as "appropriate for low temperature climates. Since Harley-Davidson engines already run warm, it is important to guard against overheating by using the proper oil in high-temperature conditions.All motor engines require oil to lubricate their moving components for performance and to retain structural integrity.
Oil is also a major contributor to exhaust pollutants so the oil you choose for your Harley Davidson motorcycle must be optimized for that specific application. You might think that an engine is an engine and what the hell, but you are wrong, every engine is designed for different oil type, in fact some engines are very particular to the engine oil you use, the older engines will not work as well on synthetic oils as they do on mineral, and the same applies to modern engines that must not touch mineral oils, and only use specific synthetics designed for them.
There are three types of oil to choose from, and changing oil frequently is a mandatory exercise to retain engine integrity and overall ride performance.
Mineral oils are the original crude oil refined for engine use. They are the least expensive of the oils and are mainly used in vintage bikes. Semi-synthetic oils are a mixture of synthetic chemicals with refined crude oil. These are the middle ground oils that combined the best of both compounds into one formula. They deliver the premium performance of synthetic oil at a price similar to mineral oil.
Full synthetic oils are made from chemical compounds mixed to produce a specific performance grade. As such, synthetic oils can be made to meet very specific requirements as well as be produced for a focused range of applications.
They are, as such, the most expensive oils on the market. Synthetic oils perform the best since they are tailored to meet specific requirements, there is a vast range of synthetics to choose from, and in this article, I present to you the five best engine oils for Harley Davidson motorcycle applications.
With this exclusive pedigree in innovation and continuous research into improving performance, its no wonder that AMSOIL has one of the best Synthetic oil ranges on the market today.
This oil is designed to reduce wear as well as minimize deposits. The contents come with a heavy treatment of anti-wear additivesand it is thermally stablecontaining maximum levels of oxidation inhibitor additives. This oil reduces engine scuffing after hoursover 13, miles. Another effect that this oil has is its thermal properties. V-twin engines run extremely hot in the summer, AMSOIL Oil is a natural heat-resistant synthetic-based oil that resists oxidation in extreme heat.
Other properties of this synthetic oil include transmission and primary chaincase protection with its stable shear characteristics. It also contains anti-rust additives preventing rust in ferrous components.
This oil is used for Harley-Davidson engines that require 15W or 20W oils. This is a top-level synthetic oil from a company that presented the first true synthetic oil product on the market. The Spectro Heavy Duty oil was developed primarily for Harley Davidson applications, as such this superior synthetic oil delivers exceptional performance grade activity specifically tailored to the Harleys heat output and mechanical movements.
This brand comes with advanced anti-wearanti-carbon additives mixed into a formulation that extends component life, reduces wear, and eliminates valve sticking.An engine's mechanical compression ratio can be defined as the ratio of the cylinder volume above the piston at bottom dead center BDC compared to the volume at top dead center TDC.
Therefore, the compression ratio is A large included valve angle requires a high-dome piston, resulting in large piston-dome and chamber-surface areas. The Ironhead Sporty and Shovelhead engines have large hemi-like combustion chambers with high surface-to-volume ratios, which increase heat loss. Also, high piston domes can impede flame travel and airflow during valve overlap, result in a heavier piston, and usually require more ignition advance.
Nooks and crannies in the combustion chamber, which are located farthest from the point of ignition and generally near the cylinder bore edges, are potential detonation traps.
Portions of the intake charge are trapped in these areas and ignite spontaneously due to heat saturation before being ignited by the normal flame-front reaction, thereby resulting in detonation. Eliminate detonation traps as much as possible. A compact combustion chamber, relatively flat or slightly dished piston top, and centrally located spark plug will provide for short, unobstructed flame travel and rapid combustion. Additionally, a large tight squish band is important for proper turbulence.
A compact chamber will also require less ignition advance, run on lower octane fuel, and be less prone to detonation and pre-ignition. A dished or reverse-dome piston machined as a sphere results in the least amount of surface area for a given volume, thereby producing unimpeded flame travel and the least amount of chamber heat loss. A performance gain is often realized when using this shape of piston dome. Knowing the combustion chamber volume is important for accurately determining the mechanical compression ratio.
The only sure way to know chamber volume is to cc it. The spark plug that will be used in the engine is installed, and the head is placed at a slight angle. The plate is sealed to the chamber with a thin coating of light grease. Use a cc burette to fill the chamber through the drilled hole with a thin fluid, then record the amount used to fill the chamber. Dual spark plugs reduce flame travel and unshroud the plug, which can minimize the potential for detonation.
Dual plugging is especially helpful with high-dome pistons that shroud flame travel and large-bore engines where the combustion flame has a long distance to travel. The second plug should be located high enough in the chamber for good combustion efficiency and sufficient clearance between the piston and plug electrode.
The engine will typically require degrees less ignition advance with dual plugs. Test and tune to determine the optimum spark advance for your engine. A leak-down tester is an excellent tool for checking cylinder sealing and more revealing than a compression tester. A leak-down test can identify leakage past the piston rings or a valve.
Stock engines typically have between 6- and 8-percent leakage, sometimes even higher. Strive for no more than 2-percent leakage. In previous Motor Series installments, we looked at component dimensions and relationships influential for achieving engine synergy, the relationship of torque and horsepower, and airflow factors. In this segment, we'll deal with optimizing engine efficiency. We all know that if you want to go fast, the easiest way to do it today is to drop in a large displacement "crate" motor.Discord stays on grey screen
With pump gas and a street-legal exhaust system, most of today's typical crate motors are good for about one horsepower per cubic inch, which results in a mild but relatively powerful street engine from just the large displacement alone. Surely these engines offer more power than a well-optimized inch Evo engine from a few years ago that was putting out 90 ponies or so, assuming the owner tuned on it hard enough.
However, if you've had your mildly built street engine for a while and want to take it to the next level without installing bigger cams, higher-flowing heads, or a larger carb or throttle body-which may reduce low-end torque and sometimes make an engine less streetable-what can you do? One thing you can do, regardless of whether you have a big or small engine, is maximize engine efficiency through optimizing the compression ratio, combustion process, and cylinder sealing.
In fact, optimizing efficiency improves power on any engine, no matter how big or small it is or how mild or racy its state of build and tune. Although increased displacement, airflow, and rpm are keys to making more power, more power will not be realized unless combustion chamber pressure is optimized and harnessed for maximized pressure on the piston.
We all know that the internal combustion engine is nothing more than an air pump. However, what we must not forget is that it is a pump designed to generate heat and harness cylinder pressure.Harley-Davidson continues to have the largest market share in motorcycle sales. Buying a motorcycle is a big investment.
A brand-new Harley-Davidson is not cheap. Before you hop on what you hope to be your adventurous and durable Harley, read this article to learn more about 8 common Harley-Davidson problems.
The cam tensioner, camshaft, cam bearings, and cam support plate are at risk for operational failure. When and if these components do fail, they could put your engine and electrical system at greater risk for further damage. Keeping the cam compartment components maintained and functioning properly is essential to engine health and the longevity of your investment.
Zeroing in on this specific cam component can make you as a buyer aware of its potentially faulty design. The cam chain system of a Harley is designed with plastic shoes that ride on the cam system. The plastic shoes will eventually wear out due to friction.
Once the plastic shoes wear out, metal-to-metal contact can occur. This metal-to-metal contact promotes engine failures which can be dangerous to you and your bike. This problem can occur anywhere from 15, to 75, miles depending on the severity. The only way to truly avoid this problem is to completely swap out the chain system for a gear-driven system.
At the very least, check your chain system shoes every 15, miles to ensure that the system is not wearing down or creating metal-to-metal contact. Bank on changing the plastic shoes in the chain system every 40, miles at the most.
Using a high-quality oil can also delay the severity of this problem. Harley also offers aftermarket oil fan coolers that can slow the wear of the plastic shoes. They also reduce the effects of friction. Faulty shift shaft seals can lead to internal oil leaks.
If you notice any fluid leaking from your Harley, you must promptly get it fixed. Over time, this leak could affect other components of your Harley and lead to a much more expensive fix. Bulb burnout exposes a rider safety problem resulting from signals and brake lights malfunctioning. At least once a month, check the lights of your Harley to ensure that your bulbs are in good working order.
These problems can be costly and difficult to repair. Touring bikes come with more bells and whistles than standard motorcycles. These extra feature present extra problems. The good news is, these fixes are inexpensive and superficial. The most common accessory issue is blown fuses. Select models got recalled due to brake problems.

Models from to with anti-locking brakes got recalled in February due to the sudden loss of braking ability. Harley-Davidson stated that this could get fixed with regular braking fluid flushes and replacing the fluid every two years. But, because this poses a significant risk to riders, Harley-Davidson decided to recall these motorcycles. In total, Harley-Davidson recalled aboutmodels. Check with the dealer to make to sure that these issues got addressed properly prior to purchasing any of the models affected.
