Sorry, didn't realize you had a Chinese bike. Your right, get rid of that pile of stinkin' crud ASAP.
*General Rant*
I am getting so sick and tired of these bloody junk bikes from China and the problems/lack of support that comes with them! I realize they are cheap to buy. There is a reason for that. They ARE cheap. Cheap materials, cheap manufacture, cheap to support if you offer NO support..... Dam, I hate 'em!
And I feel bad for the folks who buy them, but there's nothing I can do about that after they have. There really ought to be a law, ya know? If you buy your bike bike at an auto parts store or the hardware store, you're screwed. Would you buy a car from the grocery store? Hopefully not. Then whyohwhy would you buy a bike from Walmart?
You can polish a turd, but you still end up with nothing but a shiny turd.

O.K. I'm done for now..........
You're on the right track looking for a Kawi 500 or anything built by a company that has dealerships (can you say 'Japan'?)

. People love to complain about dealers, but the fact is, they are able to support the machines they sell, those machines are 1000X better than the Won Ton bikes in the first place, and in general, you get what you paid for.
Sell off that heap you got now, and get a used Japanese bike. You will
NOT be sorry you did.
**This is not directed at anyone in particular, but every DimSum bike ever made or bought, Alright? So if your offended, get over it. Chinese bikes are garbage, I didn't build the dam thing, or force anyone to buy one, but that don't change the fact that the bikes are trash. Research your bike purchase before plunking down your hard earned cash, and save us both the headache.
