93 needs a new motor

Just got the 93 running after it sat for three years. Bottom end is slappen like an ape beaten his chest!! Sounds real bad. So the questions are for those of you who has rebuilt their motors. It sounds like the bottom end has gone. How hard would you rate the work for someone who has only ever rebuilt cars and two stroke bikes and what are the costs involved? What special tools are needed to do the job?jAny advise would be a great help. Breck

Hey Breck, read through this and you'll get an idea of time and money involved for a full rebuild:

Breck,
Ya may get lucky if it's the balancer (doo) chain slapping the case, cam chain,
or just one or two doodads outta whack, like badly out of spec valves or the
afore mentioned chains.

Then again it may need a full rebuild. I haven't priced and cannot answer the burning question.

Hy Breck, I just figured out where all that fuel was coming from!!

We actually fixed the float sticking open problem. The airbox filling up with gas that quick? It was coming up from the crankcase breather. When the float stuck open it filled the crankcase, duh. Check the oil and it'll be overfilled with gas.

That would explain the thin black oil that I drained the first time as well. Remember I said that it was way over full when we drained it. Also Mike says that we put over a gallon of fuel in it on the friday. It was Saturday eve when I capped the line. The tank is almost empty now.

Not sure if it's worth the time to make it run with the sounds you said it was making. Probably better to just stop while the head/valves are good for a part out.
