Hey,
My raptor is seeming to bog down when I go up a slight hill to an extreme hill. The bike bogs only at middle throttle no matter what gear you're in. When I give it full throttle the bike screams up these hills no problem and burns out the excess gas. The overflows of the carbs drip gas. I think that the bike is flooding as I start the incline. What can I do to fix this? What are the adjustments for the different needles? I'm running a stock setup on my quad? This thing is starting to **** me off going up tight twisty hill climbs at full throttle and not having any lower rpm throttle play. Any suggestions would be appreciated

 

Sounds like you need to lower your float level. It's a common problem. Do a search type "float" in the little search box towards the top of the Yamaha page.

 

mine does the same thing. When I was riding in the smoky mountains last year, I had to stay hard in the throttle when it started to bog. I would give it full throttle to clean it out, then it would catch up and almost throw me off. It does the same thing when I ride an extended wheelie. Gas starts to pour out of the bowls and the machine bogs down. I don't know what the problem is.

I don't have that problem but I put a prefilter lid from EHS racing on my Raptor and noticed I nice boost. I have let friends with Raptors ride it and they can tell the difference also. They are ordering them too. EHS racing site
