lee harris Posted January 19, 2008 Report Share Posted January 19, 2008 A M8 has a TLR250 and the bore is at its wear limit. A WES Piston is 70,5mm, that means 0,5mm oversize but the liner is very very thin - after boring it will only be 0,80mm thick in the wall!!! . Any suggestions on either where to get a new piston and liner fitted...where are the original pistons, honda havent got anymore or, anybody got experience of the WES piston? I have been told the skirt is too long or it is too heavy. Ideas??? Quote Link to comment Share on other sites More sharing options...

In the end a very light hone of the barrel and new rings seemed to do the trick Quote Link to comment Share on other sites More sharing options...

250tlr Posted January 20, 2008 Report Share Posted January 20, 2008 (edited) Hi all.... I have a 250 which I recently got a piston from Paul Cook (T&T), it be worth getting the head and base gasket from him as well, as these are becoming harder to get hold of too, I had my 250 re-lined and for me it's the only way to go.......... because there's hardly any liner to begin with reboring you risk the chance of cracking/flairing the bottom. It be worth not to just trying to get away with re-lining the cylinder as its just as important to replace the piston as the skirt on the piston wears too. (known as piston slap) Other suppliers of RTL/TLR bits are http://www.lewisportusa.com/Images/restora...build_parts.htm http://www.econohonda.co.nz/honda_motorcycle_parts.html just finished my 250 last week, not run up yet just waiting on one part..
