When I am going about 20-MPH and give my P700 a little more gas the engine momentarily bogs down the accelerates . It just started this about a 100-miles ago. I have 600+ on my atv and this is the first problem that I've had. It is also getting poor gas mileage ~11-gpm.

I think that lowering the clip on my needles(raising the needles) might help. I think that the mid range is too lean and I am mostly running on the main jet. If anyone has a better solution or might know what’s going on let me know.

 

I've had the same problem. Only happens some of the time. I thought my needles were too rich so I tried raising the clips. Turned out to be much too lean. I now have one washer under the clip on the #4 notch. Still lean. I'm open to suggestions.

 

Mine did that, and I put a can of fuel injector cleaner in the tank, and whallaaa... no more stumble! [img]i/expressions/face-icon-small-smile.gif[/img]

 

Ditto on the fuel mileage.

 

Mine did this one time after I drove with choke on,after I turned it off it still did it till I beat the crap out of it down a dirt road. It has not done it since.
