A mate of mine wants to sell me a super tigre 61 engine. It is about 10 years old but looks to be in good condition. It will run on a bench without any problems but in the air it dies all the time.
His guess is that it needs new bearings but I dont think he knows for sure. Can you get new bearings for this motor and if so is it worth doing up this motor? He only wants $50 Aust for the motor which is quite cheap.

Thanks,

Troy.
