From Mild TO Wild! Posted December 7, 2011 Report Share Posted December 7, 2011 That depends. How worn are your cylinders? If the crank is fucked. If crank is bad I'd get a 4 mill crank and you sound like you want to get a port job. 4 mill porting is different than stock stroke. Depends on how wild you want to go. Don't order pistons till you have your juggs off. There is a ware limit. Quote Link to comment Share on other sites More sharing options...

From Mild TO Wild! Posted December 7, 2011 Report Share Posted December 7, 2011 If you go to a 4 mill Jeff at fast will hook you up. Your going to pay to much if you buy local. Wiseco is the shit don't second guess their pistons. Quote Link to comment Share on other sites More sharing options...
Finch Posted December 7, 2011 Author Report Share Posted December 7, 2011 so if cylinder is in good shape do i just figure out if its bored and all that from whats engraved on the piston in there? and again thanks for the help! Quote Link to comment Share on other sites More sharing options...
From Mild TO Wild! Posted December 7, 2011 Report Share Posted December 7, 2011 Piston to wall clearance on wiseco is. 003. You measure piston and measure bore. This I'm answering because I don't fee like being a dick. Its something you could find using the search tho. Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted December 7, 2011 Report Share Posted December 7, 2011 hey mike.....it depends on what pistons are currently in your bike....that is what depends on whether you can tell by a number what the bore size is. wiseco (as far as i know) is the only one that has the bore size in the piston number up top. Sorry earlier about suggesting a rebuild.....i did not pay attention/realize that you were in utah. 90 is not really that bad then. Its not super high.....but its not excessibely low either.

Larry's Shee Posted December 7, 2011 Report Share Posted December 7, 2011 If your compression gauge is in doubt, try another. Be sure that the thread in adaptor is same length as your spark plug. If it's shorter you will read up to ten lbs. lower. Do you have head off yet? When you pull it off take a look at cylinder walls, how do they look? Maybe post pics. If you are so inclined, pull the pipes and reeds off and look at the pistons. Are they scored badly? How do rings look through ex port? If in doubt, post pics. As to piston clearance, that has to be measured with micrometers, you can't just jamb a feeler gauge down in there. At this point I would put the cool head on and see what you have for compression. You know you could have just milled your head. But hey, now you have a "cool" head. As to search function, I think it blows major donkey balls. I've tried + and " ", but I'm computer compentancy challenged (P.C. Bullshit ). Sometimes you have to do it the old fashioned way and just LOOK. I'm sure not every thread says use search, as a lot of it has to do with how a person comes across with their "tone of voice". Texting shorthand, ghetto slang shit, run-on sentences don't fly well here. Quote Link to comment Share on other sites More sharing options...
Finch Posted December 7, 2011 Author Report Share Posted December 7, 2011 Ya as I said I'm not the best with writeing or any of that but I'm trying to do better for you guys plus I got the cool head and didn't want to mill head so if I ever decide or had a reason to I just just thro the stock head back on.
