2 spare motors: What to do?

[Billyboy]

The engine in my bike (#1) runs good, but there's a bad oil leak at the base, and a clunking that scares me.

I've got 2 spare motors.

Engine #2 came with my first parts bike. AKAIK it will run as is. I stole the condensors and clutch, but otherwise complete.

Engine #3 was in my $20 parts bike.
AKAIK: Used as a drag bike. Head has been polished, maybe ported. Rumour from a friend of the guy that used to own it of it being bored, 1100-1200cc's. Could be true, I dunno. Also rumour of a spun crank.:shock:

So I'm going to have to pull my motor anyway to fix the leak and find the periodic clunk. I was thinking of tearing down these motors and seeing what I have and what I can come up with.

Potentially, I could build a real firebreather!:-D

If the jugs and pistons are bored and in good shape on #3 then great. Maybe I can use them. I think for not a lot of money I could make something with some real power.

I can tinker with stuff, but I'm no mechanic. I'd need a lot of help from the smart guys on here that've done this before. I've got a manual, so there's a lot of help right there.

What do you think guys?

It's easy. You'll need your basic tools and some specialty tools like a rotor puller (which I'll send to you for free) and a clean area to do the work. Go slow, ask questions here, and have a great time. There's nothing better than hearing a motor you built fire off when you crank it over.

Really Hap? That's awesome.
I am definetly gonna do it. I'll just need that guidance.

I was chatting with a rider buddy and it so happens that he rode the bike that I just picked up for $20.

The engine IS bored, although he doesn't know to what. The head has had some work done to it. Porting, polishing.

He said it went like a bat outta hell! But that the crank is spun and it vibrated like a bugger.

I'm definitly going to swap out the pistons, jugs and head into my other spare motor and make a dragon out of it.

I hope that everything else is in good shape.:-D

If you have an aftermarket manual (haynes, etc.) you'd save yourself a lot of head-scratching if you could find a factory service manual, they're much more detailed and easier to understand regardless of experience. On a project of this size, it's well worth the money spent. Just wish I could find one for my GS750EX! That, and a starter clutch.....

Good luck, buy plenty of Fast Orange, and I hope your dragon breathes fire soon!

Thanks guys. I've got a factory manual, a scanned, pirated copy from an online thingy. I'd send out a copy to anyone that wants it by email. PM me.

I believe this is my 2000th post!
