I was wondering what the stock compression ratio is on an 02 wide glide and was also wondering what compression ratio on a 95" I could go to without using compresion releases. I want to run 211 cams with the upgraded cam plate and oil pump but with that upgrade I want to order the right ones.---jack

Not sure what stock compression was but have done many 95'' kits with 211 cams & S/E high comression pistons and never put compression releases in any of them, also never had to put a new starter in any of the bikes, and it's been years.

Thanks BUBBIE; That is the kind of info I was looking for. I just want a good running crisp response scoot without getting rad and still maintaining easy starts and good reliability. I'll see if they make a 9.8-10.0 pistons or thereabouts. I already have 95k on the bike and don't want to overpressure the lower end.

Well, I ordered up the 95" teflon lined forged pistons (9.4:1) and cylinders, got the upgraded cam plate and pump, got the 211 cams and n65c needle and 195 main jet. I also just received all the tools needed for the job from Georges Garage,nice tools. So as soon as the parts show up (probably tomorrow) I'll get started.

5.3L Factory Spec Cylinder Pressure
During the compression stroke, your car/engine’s standard ‘ideal’ cylinder pressure may have been set. If your vehicle was equipped with a factory/service manual, this value would be listed there; however, you should keep in mind that it will represent a theoretical pressure that you are unlikely to encounter during real-world testing.
Symptoms Of Low Or No Engine Compression in 5.3L
An engine’s compression might be either too high or too low, although a few unusual situations do exist. The compression issue causes the engine not to start, or the compression problem allows the engine to start but with a misfire condition.
What Tools Do You Need?
A compression tester is the most crucial tool you’ll require. Because the spark plugs must be removed, you’ll need the following essential tools:
How to choose Compression Tester
There are several different types of compression testers available, as well as a number of locations to buy them. We recommend:
Dry Compression Test
To obtain the most precise diagnosis of your engine’s health, perform the compression test on a slightly warmed up engine (not a running engine).
Relative Cylinder Pressure
Each cylinder’s pressure should be checked and compared to the remaining engine cylinders’ pressures. There should be no cylinder with a pressure less than 75 percent of the highest recorded value.
Abnormal Compression
Try the test again if you read an incorrect low value. Loose fittings or other problems might cause you to interpret a wrong low value.
