Description
Maico GM 500 85/86 cylinder and head . Used condition. Liner is scored and will need a rebore or new liner. I measure the diameter at 87..4 mm The biggest piston I found available to purchase is 88.5 . The scores are above the exhaust port see pics .it may bore out to the top size or it may need a new liner. The water feed on top of the head has been hit but will still work ok . Thanks for looking
