What is the largest I can bore my 85 lt 250r, in dennis kirk catalog they only list pistons to .040 over, but that doesn't seem like it could be right

 

im asuming that u meen with out a big bore it would i think be .75 or .80 not totally sure though

 

Yeah just to back you up Nostradamus it's .80 over which makes the bore 72mm, so there you go Spandexgranny. I think some places can make a stroker kit also.

 

I looked in my Wiseco catalog and second what LT250RSuperstar said, .80 is the max. Just in case you need it, the Wiseco part number is 534P8.

 

Thanks Guys, I'll tell the guys down at the Machine shop and see where we can go from there, I checked it on my caliper and it was about 70 over one direction and about 80 ove rthe other direction.... may be time for a sleeve
