I removed the JB weld around the clutch cable guide and ghetto-fabbed a new bracket. It all works but i would be happy to get suggestions on how to make it look better.

I am thinking a coat of silver VHT paint - same as the forks. I suppose the whole deal will look better when i get the cases and cylinder head vapour blasted too.

I'd remove the barrel too, and clean barrel and head off bike.
Save a lot of flushes of coolant.

black frame looks good with yellow tank - the blue seat cover is ok for now but might get swapped out for charcoal or black later on.

cracked piston. measures stock size 66mm so i will have to search for another one. ebay japan seems good for NOS pistons, rings and gasket kits.

This model also shares the same engine as Arctic Cat ZRT600 snowmobile and there are thousands of parts around for those. Suzuki "Spirit" engines.

lucky catch with the piston.
Not much blowby, so prob low hours, but cracking seems unusual to me.
Cracking usually happens with mega hour pistons.Maybe measure up the barrel for clearance

or from getting caught turning the motor over with the barrel off.

PO said he managed to get the bike running when it arrived at his house - after a few years of sitting - he then explained that it revved its tits off until he worked out how to switch it off - then he pulled the spark plug lead.

So maybe that period of high revving with prob zero lubrication may have caused the damage.
