Oh thanks for the offer, only If I had known before. My cylinder is already gone to the engine builder...Just for fun, how much would you have charged for the porting ?


Thanks,

mid forties is very possible. supposedly that is whay my current combo yields. and it feels quite strong....especially in the revs! i lost some bottom end power but picked up much mid and top. dont follow me on the trails[img]i/expressions/face-icon-small-happy.gif[/img]

Should have read 'Head Work For A 250R' [img]i/expressions/face-icon-small-wink.gif[/img]


EDIT: Edited it before someone starts joking about it lol

 

I would try the cr gasket before doing any head work or just use a outer gasket for your R. I just shave my head .015 and put cr gasket on it and done a compression test on it and it way to high on compression 225 psi. thats just kick it over it will proble build about 250 or so running. I was told to stay under 210 psi or it would start pushing spark plugs out and its a good ideal to do a compression before you do all that work like my dumass didn't do.
