  2. TY 250 piston stamped id markings

    Hi thank you for your post due to the age of the bike and not knowing it's past history I thought I would play it safe and replace the little end bearing and replacing the rings etc, the bore is in very good condition, your post has been very helpful, may be a rebore and new piston is the way to go or am I being to fussy the bike runs well but has a bit of piston slap (is this usual for this type of engine). Thanks for your help.
