can anybody tell me where I can get standard 94mm piston set , yes I can get piston and barrel sets no worries I can also get 94.25mm piston set but I just want 94mm cause my barrels are in good nick no wear and I want to save a few dollars ok lets have it .

if your barrels are ok then what's the prob with your pistons?

had a valve seat come adrift, some damage to pistons , plus slight wear in pins

oh. now I understand why !

yeah its ashame cause I bought it not running looks like it was good motor , no oil leaks ,nice n clean but must have been dodgy head job eh
