Topic: 2 Stroke help

[tylerdb]

Found a crack in my cylinder wall by the exhaust port, looks like spider webs. Is getting the cylinder replated the best option? Think I could get away with just a piston and rings for the next few months so I can replate this winter?

single, twin or triple?   Replating?  not too many 2 strokes had plated cylinders( IIRC Bridgestone was one).  You could get by but since it is apart, do it right.  Some bikes had replaceable cylinder liners...Larry

Looks like a sleeve. If it is plated the barrel looks to be pretty damaged. 2 Strokes are harder to sleeve because you need to match up all the ports, might be cheaper to find another cylinder unless they are made out of unobtainium.

the hard crome is peling off...so a dead end..get a new cylender if it are a common modell..or get it bored aut re hard cromed use the nicrasil type..id it are one of its kind engine..

just wants a small weld and a re plate , i have repaired much worse than that one .
would not use it as is though you will just ruin the new piston and ring , it wont be hard crome it will be nicasil . i dont know where you are in the world but here in england
it would cost about 140 quid to repair and plate it .
