scrambler 500 help
i have a scrambler 500 2003 model. i put a whit bros. e-series exhaust and a kn filter and jet kit on it. it runs really well but seems to lag a little bit when you gun it. then it screams lioke a bat out of hell. i was wondering if somebody could help me out on the bogging problem when you hit the throotle. i put a 165 main jet in it and put 6 1 inch holes in the airbox lid. the plug looks preety good on burn tests. thanks for info.

I have the HPD powermaxx exhaust and ran a 160 main jet with the air/fuel screw turned 2 turns out. Then I put the HPD high flow intake lid on and run a 170 main jet, a special needle jet modified by HPD, a special spring that they supplied, and the air/feul screw turned 1.5 (?) turns out. Did you do anthing with the needle jet? That may be your problem. If you can spare it, I would recommend you get the HPD air box/carb mod. It comes with a big hogh flow aluminum scoop that you rivit onto the stock lid as well as everything to recalibrate the carb. It eliminates all the guess work

The scrambler carb is a CV carb. It uses a vaccume to open the slide. If you reduce the vaccum by drilling holes, you MUST recalibrate the carb so that the slide will still open all the way. That is what the new spring id for, as well as the modified needle jet. Those holes in the lid may very well be the problem

Bigbad... I noticed you said that you adjusted the fuel/air screw out 2 turns with the 160 main jet. Not trying to argue but my directions said to go 3 full turns out from slightly seated with the powermaxx exhaust. How critical is the adjustment of this Fuel/air screw? I also got the 160 main jet in this kit.

I was probably wrong. I was trying to remember from when I installed it last winter. Then again, my instructions may have been wrong too. Cuz I actually got a 165 main jet with it, while everyone else that I have talked to got a 160 main jet. Did you get a 160 or 165?. With the air box mod I believe that the screw gets adjusted 1 1/2 turns out. OOPS!
