Hey thanks for the advice... i have a 12 tooth sprocket on order, and i am sticking with the 155. Im gonna take some extra jets w/ me just in case the gearing doesnt help. Thanks again!!! Bansheesmoker, you goin to dumont halloween?

 

Yeah don't worry its kind of hard to hold 6th gear on the 86's because they have different gear ratio's than the 88-89 (best for duning)

My bike has a full drag port, custom dome, 39mm carb, boysen cr250 reeds, im running 12/39 gearing and I cannot pull 6th gear hard. Though I weigh more than you (290) my bike pulls HARDEST in 3-4th gear and that is with 20" sand skate II's. With 22x11x10 10 paddle extremes I cannot hold 6th at ALL.. it will just bog like a ****, atleast with the 20" paddles it holds it but doesnt pull at all.. i lose speed. Though im trying to sell it so a lighter person would probably haul *** on it.

 

Ok guys... I got a 12 tooth front sprocket, a Boyesen rad valve, and a brand new 36mm PJ jetted by Duncan racing. I am hoping this will give a gain for me at the dunes. I am going to go ride tomorrow and will let you know how it does. Anyone know how much of a diffrence a brand new 36mm PJ will give me over the stock worn out 34mm? thanks

 

My 86 did the same thing with Sand skate IIs. It had a few aftermarket goodies on it like a 39mm carb, K&N with no lid, and full FMF. It would not wrap out in 6th and would loose speed. After decking the cylinder to get more compression, a mild porting job, and bored to a 265, I do not have this porblem.

 

Socal, If your quad smokes when you first throttle it then it's not a main jet. It's either the pilot or needle. Plus if it was to rich it wouldn't smoke. The smoke is either the oil your running or the mixture.

 

Ok i went riding with all the new goodies and it is running great. Only complaint i have is i was having trouble keeping the front end down in 3rd gear.[img]i/expressions/face-icon-small-wink.gif[/img] Thanks for all your help everybody, I guess the next thing i will do is get a pro circuit pipe.
