Help...

So on a spur of the moment decision, after checking CL everyday for a few weeks looking for a smaller 4wheeler for my daughters to learn on and ride, I bought a 1988 Yamaha YFM100 Champ atv.Pic of what my bike looks like

Anywho...When I picked it up, It needed a battery but the owner push started it and it fired right up. Smoked a little but still ran good. I rode it, went through all gears and all brakes worked fine.

Well, since then...after I brought it home and looked at it further, I think I may have bought a money pit

It needed a battery so I got one. When I put it in, it cranked over fine but would not start at all. Seems like the carb is flooding it out.
The carb screws are in poor shape.
Intake boot torn in half (have new one ordered)
May have weak compression as well but my tester won't adapt to the spark plug hole.

I'm now having a hard time finding parts for it. yes, BikeBandit has a lot of stuff but there isn't squat on ebay.

Here's is where I'm hoping to find some help...

Anyone have any sources to find parts for older bikes?

I don't mind putting a little bit of money in it. It has a new upholstered seat, new tires, good brakes, good gear box. Over all, the bike is in decent shape.

Looking for places to find affordable top end kits...piston, rings, cylinder, carb...

I'm gonna try and see if I can get it running after messing with the carb but I really would like to find another one to work with...ebay isn't helping much though...hardly nothing on there for these bikes

Anyone out there with experience finding parts for these older Yamaha's that can point me in the right direction would be helpful and appreciated.

My daughters have had their heart set on a 4wheeler, I found them one and they can't even use it




Oh...Here is the info on the bike

Good Deal...Thanks again Kristen. The bike seems to me to have weak compression. Cylinder and Piston and ring set isn't too expensive so I may end up fixin it.

If I can could find an adapter for my Automotive tester I could see what the compression actually is

Sourced out and found a good carb on ebay finally. Received it yesterday, cleaned it all up and tossed it on the 4wheeler. Got it running and it actually runs pretty good now and starts right up with the starter The motor still has some age on her but I think it will be fine for what I need it for.

Ordered a few things I needed from Boats.net today Kristen. They wound up being a good $10 cheaper then BikeBandit by the time my order was complete.

Thanks again Kristen for directing me to them...You rock
