Can I make my 440EX even faster and better at hill climbing? I have the following mods:

IMS 440 kit, proper jetting, FMF powercore 4 pipe, White Brothers race cam and revlimiter and K&N air filter w/ a modified air box. I have the stock head pipe still.

I hear about sprokets and a few other things but havent heard any first hand experience. My quad is very fast and beats the crap out of every stocker I come across but it doesnt seem to have the ***** my old banshee had....any suggestions guys?

 

sorry dude, no suggestions, but ihave a question for you... was there a giant dif. from ur stock? i am condiering getting one in the futer and is it what everyone thinks?? amazing??

I would get your head ported next. I would suggest GT THUNDER, they have my head now and they are race porting it with a 3-angle valve job. The porting will give your Quad more flow, but you must get a better exhaust system to take advantage of the porting. For the exhaust I would recommend the complete DMC or the white bros promeg complete. With these extra mods I think that it would fix your problem. But I do not know where you ride? DUNES? If you ride in the dunes and need more climbing power then get 13/39 sprockets, lots of low end power and torque.

 

It depends on what you are wanting, if you are wanting "low end power" and not a whole lot of top speed, (probably about a top speed as a regular stock 400) you should gear you quad down and put on something like a 13 or 14 toothed front sprocket, and t a rear sprocket of about 39-42. That would make an incredible ajustment through all your gears. Now if you wanted top speed, you should gear it up, and put a 16 toothed front sprocket, and a 37 or 36 back.
