    Engine Trouble Multiple engine problems.

    I have come across a few problems. The bike currently runs fine but there are a few things that worry me. 1. The engine is spewing oil. It is coming out of at least 2 places. The first one I noticed is out of the exhaust gasket. It drips a little. The second and probably more serious part is it...

    Exhaust Oil leaks...

    I've got oil leaking from the exhaust (where the gasket is) and the cylinder head. Is this a problem?

    My petcock is useless

    Whether it is on or off, fuel goes through. I can run my bike in the off position. So because of this, fuel can freely go through when the engine is off and I can't do anything about it. Will this hurt my bike or is it fine?

    Carb Leaking

    I just filled my bike with gas for the first time. I was priming it and then after a few pumps, fuel started coming out from the primer and from under the air intake. Anybody know what is going on? This is my first project and I know how engines work but I'm no specialist. Thanks in advance. :)

    Odd petcock issue

    I've posted about my leaking petcock, I think I have figured out the issue, I think it's machined wrong internally. When It's shut off it seems to be "off" however if I turn it to the left or right of off, if I turn it all the way to the stop the valve seems to leak, however if I just turn it...
