I own a 87 mojave and i have put a White Brothers e series exhaust, k&n air filter on it and it did not do much. What else can i do but for not much money?

 

Mojave87,
Well, for openers, what exactly do you want to do? Better low end, better mid range, better top end? The phrase "more power" means little unless defined.
How many discs are you running in your WB?
Not sure about the stock number, but I think it is 6 or 8. Adding more discs will increase mid range. Adding still more will increase top end. Adding ANY discs will increase db level of your silencer.

What type of racing are you doing. If it's MX go for suspension and handling before you go for power, Remember the race is won in the corners.

I am running the stock number of discs i think 6. I want more mid-range to top-end. Is it true that the mojave is geared lower? Can that slow me down on top-end? Yea i plan on racing in the future after i get my quad the way i want it. Thanks 4 the help!

 

You can add more discs for high end performance. My Supertrapp discs come in a six pack but I have no idea how the Wb discs are sold. You should have received some paper work with your pipe indicating the max. no. of discs to run. If not I'd start with six additional discs & see how you like that.
If you think your gearing is low, count the number of teeth on your c/s sprocket. If you want to gear up just get a one tooth larger c/s sprocket.

Thanks i am going to order a pack of 6 dics and 1 tooth bigger sproket in the front. If i drilled holes in my airbox lid and put vents in would that help my power? I still need more power!!!! Please help!!

 

Mojave 87 where do you live? Get razr tires all around that will improve your bottom-end if you get smaller tire get 20x10x9 on back and 21x7x10 on front better turning and bottom end

 

I was going to get 18x9.5x8 fast treakers on the back and 22x8x9 on the front. What do u think of the Fast treakers? I live in NJ.

 

If you want more top end do not get 18" rear tires this will kill your top end speed, it will however help your low end speed. Also try a higher compresion piston, and a new cam this will wake up your 13 year old quad.

You could also loose the airbox lid (if equiped) and richen your main jet. You did raise your main jet for your exhaust upgrade, right? If not you are running the engine lean and it will not be much of a power increase..your just putting the same gas with more air.
