Hey guys. New member here...I've had a few three wheelers through the years, but never a 2 stroke. I recently bought a 1984 Honda 250R ATC and a matching parts bike. The complete bike is in pretty good shape. The parts bike is in multiple boxes. Anyways...my questions...
When I purchased the bike, the owner said that it would need either rings or a crank seal, due to the smoking. It does smoke a lot. My fuel mixture is around 40:1 on this tank. But in addition to the smoking, it spits oil out of the exhaust. And in the expansion chamber, there are some holes in it from sitting I'm assuming. You can see smoke come from it while at higher revs. Would the holes contribute to any of the smoking? Also at certain thumb level on the throttle, it acts like it's flooding out some...I'm assuming the holes in the exhaust would have something to do with that.
Are these symptoms normal? I know 2 strokes smoke, but this trike smokes a lot. It's white smoke. I'm going to switch out the exhaust for the one on the parts bike to see what that does. Does it sound like I need some new rings? or a crank seal? It has pretty good compression, haven't had a compression test yet.
Also, where is a good place to get parts for these bikes?
Here is a picture of my $900 investment. You can see the parts bike in the back.
