Here's the deal. Back in Feb. I purchased an 07 SSR 250 water cooled quad.

Unfortunately since that time, I've had problems with it running lean and have had the hardest time getting it to run right. Basically once I get the quad going and I lay off the gas from about 1/2 ~3/4 throttle I have a huge backfire (gunshot level) and the quad wants to stall out. I'm assuming this could be due to a lean condition.

My question is, there is a Sheng Wey carb on this thing. I've brought it to several dealerships and nobody seems to know what jets are in the carb. I've had two dealerships tell me that a Mikuni main will work, but they've never seen the pilot jet before. I've even had them give me a Mikuni Main jet, but after inspecting the jet it does have a larger top portion than the one that's in the carb stock. As an experiment I threw the main in the carb and started up the quad. Once warm and the choke is turned off on throttle it stalls out.

Does anybody know what type of jets will work with this thing? I've read in other threads that it uses Keihin. Please help...this quads been sitting in my garage since feb!!!!!! Thanks in advance!

 

Try here these guys fool around with jets alot from what i have read.
