i have installed the sprocket set, headers, cdi to get 1000 more rpm and my 2001 ds650 has less than 40 hours so it is like new but i want to beat a friend's raptor and i still can't. what can i do?

 

i have won against lots of stock raptors with my STOCK ds you should have no troubles with a modified ds....whats the raptor got for mods?

 

headers, pipe, and k&n filter as far as i know

 

is this a drag race, if so he prob could take off faster but you should have a bit more topend..atleast thats how i found it when i raced some around here

 

it was 1/4 mile on sand dunes and first i was beatting him but at the end of the race he won and we played like 3 times so i am planing to race him again but i don't know what to add to mine to make it faster without spending too much money

 

KMDuner has a high compression piston.

Drop that in and your friend will wonder what hit him.

 

I have a 2004 baja with stock gearing a Ron Woods header and pipe a dynojet kit with K&N filter jeted with the air box lid off I beat most raptors by a few bike lenths.
I have not ported my intake manifold but plan on doing this in the next week or so .This might help you beat the raptor. P.S all my friends and my sons ride raptors and none have beat me yet except for the ones with high compression pistons and cams and portwork.

GOOD LUCK and kick some Raptor BUTT

 

i will get the k&n dynojet kit is ebay the best option to get it right? i saw it for 47.99

 

If you could get the K&N filter and the dynojet kit for 50 bucks that is a screaming deal. I would do that and also look into porting the intake manifold you will see a big differance. You need to let that monster breath. Also after you do these changes make some runs and make sure you don't run out of gears so he can't catch you at the end this time.

Good luck and kick that raptors butt.

 

start out in second gear, slipping the clutch off the (this takes some practice) line, then don't use the clutch anymore when you shift gears (let up just slightly on the gas and shift up at the same time,called speed shifting) this will greatly improve you'r straight line speed!!!!
