It may be from the steam. My 450 was doing that, and Carl rerouted the air vent hose(I think) to go up a little higher and it never did it again.

How much water cam out of the carb drain? Mine always has a FEW DROPS come out when I pull the plug in the drain after riding. Did you put Dielectric grease on the spark plug? If you did you may want to hit it again. I have to regrease mine every 3-4 rides. Sometimes mine will sputter in the water, but after it gets fresh grease it is good to go for another few rides.


I run a DJ170 (per the kit) and Robb uses a DJ175.

Question

When you say you are running a 170 or 175. Is that Kehein? The reason i ask is my dynojet kit come with jets upto 160. My oem jet reads 162. Ive heard the oem jet is in Kehein and Dynojet jets are different.
