Engine rebuild help

[super8]

I have an 85 tri moto 225, and would like the engine/trans completely gone through. Doesn't run bad now, but have a mysterious noise and the trans has started to slip a little. Does anyone out there recommend a good engine shop? Thanks for your time!

prolly the timing chain or valve niose you hear and may need new clutch's. i believe there may be a clutch adjuster on the side of the case you may be able to get the clutch working better.. good luck..
