Hey guys, I just bought a 2010 Quannon 150 from a dealership about a month ago, it had 5 miles on it when I got it. I've been having problems since the day I brought it home. First, it wouldn't idle right, it would bog down at low rpms, and sometimes even stall at intersections. After doing some research online, I found a service manual that said it might be bad gas.
Here's the thing. The dealer I bought it from has had it sitting for a while (2010 model, built in 2009, had only 5 miles on it) and I assume they never drained the float chamber like the manual says to do for storage. I decided to drain the tank and put fresh gas in it. Once I got it running again it acted a lot better, it wouldnt die anymore and it would finally idle, although the rpms would go between 2k to 3k. I did some more research and found that it was probably a clogged slow jet from all that old fuel. I called up a local Kymco dealer and they said that they would need to clean the carb, which is a maintenace item, $100. I politely said f*** that, and decided to do it myself. I took the tank off AGAIN, took the airbox out, then the carb. I boiled the jets in water and put everything back together. I also checked the fuel filter to make sure it wasn't clogged. When I got the bike started, it purred perfectly and I was able to get it to idle at 1600 rpm, which is where it should be. Before, it would die under 2000 rpm.
The problem is, I don't think my auto choke is working. The bike starts up but the rpms stay consistant and never raise. It takes a while for it to warm up to the point where I can twist the throttle and get smooth feedback from it. It doesn't seem to like 3/8 throttle, it sputters a lot. So now I got a new bike with less than 300 miles on it that still doesn't run right. I mostly blame the dealer for not storing it properly and not the bike itself.
What do you guys think? The dealer I bought it from is 150 miles away, and I'm making no plans of going back up there. Hopefully the local dealer will help me out.
