hey guys, i have two machines, a sportsman 500 and 400. Me and my buddies go out riding a lot and i was wondering if anybody knows how to make my 400 faster to keep up with my friends Sportsman 500 and honda reacon thats inexpensive. If anybody has any ideas please let me know.

Put on a SupertrappIDS2 pipe and a K&N air filter.And rejet to the pipe.Makes a world of differance.

 

Thanks man... about how much will this cost?

 

I found my pipe on ebay for $100 new in box but if you get one from a dealer it runs around $250 and about $50 for the filter.Well worth the price though.

 

if i put this stuff on will it be worth it? so far iv gotten my 400 up to about 58 mph on a 2mile long road. so if i put these modifications on about how much faster will i go.

 

Look at how I have my 425 set up.Filter,pipe,clutch springs.It isnt all that fast but it has power out the butt.If speed is all you want get you a sport bike not a 4x4.This 425 will keep up with my 400 2 stroke but gets blown away by the sport bikes till we get in the trails.

 

im just lookin for about 10 more Mph's. im already thinkin bout the predator. ill try wut u told me to do and keep u posted.

 

You wont regret it.My next step for my 425 is a 500HO cam.

 

a filter and clutch kit works good.
the pipe doesn't give much gain,and costs alot.

a cam will give more top end power, and soo will a bigger carb.
and a big bore will give more power across the whole revrange.

 

ftwflh... wut was the fastest top end speed u got out of your 425?
