How much compression should a Harley Davidson have?
Reference Your Manual This engine, for instance, should have no less than 90 lbs of compression and the cylinders should not be more than 10% apart from one another. If you suspect that your motor is worn, or damaged; consider a motorcycle compression test before moving forward and disassembling.
How is cylinder pressure optimized on a Harley Davidson?
For optimized cylinder pressure to occur, heat must be contained and converted into usable pressure on the crankshaft while minimizing heat loss to the cooling system. Of course, a balance must be achieved between maximizing heat and minimizing its harmful thermal and mechanical effects on components.
What should the compression ratio be on a Harley Davidson?
This has several implications for the optimum ignition timing and the required fuel quality. An engine with aluminum heads can usually support a compression ratio of roughly 1.0 to 1.5 points higher than an equivalent cast-iron head engine without incurring detonation.
What should the oil temp be on a Harley Davidson?
Oil Temp 225-240 seems to be the norm. This all depends on where you ride and riding style as Bob mentions in the videos. As we all know, oil coolers work to cool the oil and a cylinder fan works to cool the engine.
Where is the fuel pump regulator on a Harley Davidson?
Fuel Pressure Regulator – Alsolocated in the fuel tank, the regulator controls fuel pressure between 55 and 62 PSI by returning excess fuel from the fuel pump back to the fuel tank. The return is also located in the tank, hence only one line (supply) coming out of the tank.

Of course, a balance must be achieved between maximizing heat and minimizing its harmful thermal and mechanical effects on components.
What to do about brake pressure on a Harley Davidson?
I put new handlebars on my 2000 Sportster which involved disconnecting the front brake cable and replacing it with a longer one. Figured while I was at it I would replace the front pads, clean up the caliper and put in new fluid.

How does the fuel injection system work on a Harley Davidson?
Ion Sensing System – This system uses ion-sensing technology to detect detonation or engine misfire in either the front or rear cylinder by monitoring the electrical energy at the spark plug after every timed spark.
