I took my quad out today for the first time since adding a tm45,ported intake, vorteck ignition, and also had to get those 22 inch mud machines tires everybody was talking about. The machine has a bad bog all the way up to about 7000. What should I do. I have the stock 16 tooth front gear on front but that can't make it bog as much as it is (but I did just order a 14). When I give it about 3/4 throttle off idle it spits and sputters then goes through the rpm range as a dog in all gears. help

 

Guess[img]i/expressions/face-icon-small-happy.gif[/img]rop the needle 1 notch (leaner). what do the plugs look like?

 

My plugs are wet. must be rich but whats the fix?

 

just for the fact tht it is reving to 7k means that the main may not be that far off, dropping the needle will lean everything from idle to 3/4 throttle. what size main is in there now?

 

I don't know what size is in it now. I just got it from on dunes performance last week and they set it up.

 

is the ac pump active?? make sure it is not giving a huge squirt of gas.
