Re: serious loss of power
do you have any oily residue under the mag cover or under the clutch cover all of it will be where the crankshaft comes through the crankcase on either side? you might have a main crank seal leaking/going bad and oily poo with some black dust is a dead giveaway of a seal leaking. some engines are assembled with seals that are damaged when they are assembled they will run fine for awhile then get to running sorry and keep getting worse until you either trash out the engine from it running lean for hopefully find the problem before it gets that bad.
