    Gas leak from exhaust and clutch cover

    I'm getting tired with these motors. Every week I face a new issue, today my engine had started to leak gas from the exhaust. I was so frustrated It was working fine yesterday running 20:1. It had rained overnight tho. I went to see if the clutch was the issue and when I pulled off the clutch...

    eBay carburetor air leak proof?

    I bought a carburetor on eBay because my delarto sha clone was making me lose power. This carburetor is supposed to be better. I bought it and it said 3 day shipping, it took 2 weeks to arrive and came in a smashed box with a cracked air filter housing. When I put it on the bike it turns on...

    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...

    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...
