Hey guys !
I took the cylinder off the LT 500RK tonite so I can get the one of the stud bolts heli coiled
tomarrow. It's lookin like it's gonna need a bore job the bottom of the cylinder is scored
in one area not too bad but I think enough. What # do I go by on the piston do I go by
to see what size is next? The top # is 1.50 does that sound right?? theres other #'s as well
but thats the one that stuck in my mind.So whats that mean if thats the right # has it been bored
out before or is that the standard stock piston?This is new to me so forgive me if I sound stupid.
Thank you guys !!!

 

best thing is to measure it with calipers and see the exact diameter in millimeters. Or like you say look all over it for whatever numbers are on it. Look for something that says in the ballpark of whatever the bore is on those, probably 88 or something.

 

when you take it in to get bored have them measure it or if you have the right calipers then you can do it yourself.they will tell you what size it needs to be bored to.that depends on the scratches or wear in the cylinder.like when i took my 250 cylinder in to get bored it was alredy bored .10 over but i had to have it bored out to a .30 over to account for a deep scratch made by a piece of broken thrust washer.
