My friend picked up an 06 raptor 350 for $800 a few months back, we just got to looking at it. He bought a replacement carb cheap on eBay, we replaced the main jet with a dynojet 128 and put it back together. Thing basically doesn’t allow you to give any throttle. I’m very new to carbs and trying to figure it out but I don’t really know where to go from here. Quad is completely stock. Main jet is 128. After about 1/8 throttle it bogs out and shuts off. Where do I start?
