I have a 1989 suzuki quadrunner 230 e that has problems.
1. Front drive sprocket is worn. Do I have to replace front, rear sprocket & chain?
2. The cylinder head somewhere in the front and the head gasket are leaking oil. Could this result from the bolts not being tight enoufgh?

3. The engine smokes blue smoke at higher rpm's. I just had the top end professionaly rebuilt and carb rebuilt too.

How do I fix these problems?

Does any body have the specs for the correct tuning of the carb?

Any help I can get would be greatly appreciated

 

Specs for the carb: Should Idle at about 1450 RPM, screw the idle screw all the way in, and back it out about 2 1/2 turns and go from there. I would Replace it all, might as well have them all in the same condition so you don't end up replacing them later on due to inequal wear.... I would say it has too much Oil in it if it smokes blue, and torque/tighten the bolts on the Head to see if it stops the leaking. Get back to me if you run in to anything else.
