What main jet do you run on your 50cc 2T? Please mention your air/ exhaust/ CVT setup (roller weights) I'm running a 90 main jet now, with a de-restricted leo vince zx-r pipe, 6 gram rollers, and an aftermarket stage 6 air filter. I de-restricted the pipe yesterday. Yesterday the bike ran pretty good and I got it up to 46, though it was bogging lightly.. Now it bogs from quarter throttle, all the way up through mid throttle, quits moving in the mids, and sounds terrible.. I'm guessing it's due to the increased air supply, because when the air supply was restricted via the exhaust cone, it ran o.k. with the jet I was using.. Do I need to increase the size of my main jet to a 100 or so to increase my gas to air ratio? What are your thoughts?

Thank you!

Actually Peters, you and Vivo were wrong. The fuel inlet was #1 and the overflow fitting was #2. This is the reason my carb was peeing gas and choking out. I figured it out by blowing in the holes.

The scooter has sat around for two months without being used too. I don't see how that would influence the flooding, but that's just another detail I wanted to add. When I have the carb flipped upside down, which way should I move the float up or down? I'm kinda confused as to how it works. I tried lowering the float so it engages the needle sooner, but it's still pissing gas and sound like a sick bubbling baby, that's when I try to start it. It doesn't run at all! I'm so pissed because I need this for a interview and date tomorrow!!!!!!!

Vivo, how would I adjust the float?

btw the thing is clean inside and out and it doesn't leak from anywhere else. Only when I attempt to start it does it start seeping out..

I don't have a garbage exhaust to use.. They shipped it via some table rate, which I don't know what is. I specifically asked for a tracking number and one was not provided. This is after I wrote them, after the 4 days they failed to ship it by themselves, like any reputable company would. I ordered it on the 12th. I didn't wait long at all to write them back. There are three companies Kymcoforum should not use, Scootertronics, Scooterpartsplace, and Scooterpartsinternational. Be careful guys. I have been waiting to get a new exhaust for two months because of these expletive deleted companies. I can't wait for the part to get in, if it does at all, because once it gets in they are going to hear it. They also failed to respond to me over the phone after the dozens of phone calls I've made because their line always goes to a message machine (SPI) I've done a ton of business over ebay and have dealt with normal companies and bad ones, unfortunately. This is not how business is done.
