I have an LT250R that I need to get the cylinder bored on. I dont know the original size of the bore though and need some help. I dont trust the local shop in my area to do it or give me the correct information, I actually plan on having the work done by the local Harley dealer and they may not know the original size either. I thought it was 70mm but can you confirm this for me.

 

go to your local dealer, and buy a Clymer manual!! ASAP [img]i/expressions/face-icon-small-smile.gif[/img]

 

I have a Clymer manual but couldnt find the info on it at the time. The cylinder bore is 70mm stock. Pistons sold that I've found so far are 70.5mm (.020), 71mm (.040), 71.5mm (.060), and 72mm (.080).
