I have a 2003 FLSTS with a 88B motor. does anyone know how far the heads can be milled.
Are you trying to get higher compression, or are your heads warpped?
This will change the compression ratio and you will need to check valve clearances You can make up that change with thicker head gaskets if you find the compression ratio to be too high Compression Ratios
I installed a crane long duration cam and its peak power is achieved at 10.1 to 10.5 compression or so the manual tells me. I do a lot of riding an want the most I can get without incurring to much heat. But like the army I want it to be the best it can be. I have milled 50 thousand already and was thinking about another 20. Hence my original question.
Have you calculated how much to take off to achive what your looking for? Try this:RSR Static Compression Ratio Calculator
