Four Wheel Forum

I had really wanted to get the engine in my bike running before I tear the bike down for a rebuild, but I think I may have to change my plans. I was looking things over today and found a ring of rust in the left cylinder. It looks like the PO got water in the cylinder when he washed the bike without an exhaust system installed before listing it for sale. On the plus side it also looks like the top end was rebuilt but never fired up as there is no carbon build up and the exhaust valves look like clean bare metal.

Before I pull the engine I was wondering how heavy is it? While I have the top end off I will go ahead and pop the side covers and detail the case, look at the cluth and all that fun stuff. What is easier to loosen or break free while it is mounted in the bike vs chasing it around on a work bench? Any tips or what not to do's?

While the engine is mounted I suggest:

Drain the oil
Remove the starter and disconnect the starter cable from the solinoid.
loosen the side cover screws-remove he side covers
remove the kickstart arm
remove the shifter
with the chain still connected:
loosen the sprocket screws
loosen the flywheel bolt
disconnect the fuel line, throttle cable andair filter

After loosening the engine mounting bolts I place a small hydraulic jack under the engine. I lift the engine slightly then remove the bolts and lower it

Was gonna post engine removal section from the manual but you got it covered.

Thanks that is exactly what I was looking for. I was leaning towards loosening the side covers but I would have missed the flywheel.

Thanks,
