I have a 04.5 sp 400 and looking to do some mods. Problem is that I dont know where to start. Looking for suggestions on what to do for more power.
Like exhaust but what brand, type and where to buy.. what else can I do.
PLEASE HELP!

 

Hi man, it all depends on how much money you want to spend on power upgrades and how radical you want to go oh and also your riding style. Normally people go with a exhaust, K&N air filter, re-jetting kit for the exhaust, clutch kits. If you want more info on any good products email me at chris77416@hotmail.com. 07 800 sportsman, head porting, high perf. cam, advanced timing key, bored throttle body, K&N air filter, power commander usb, full high velocity exhaust, polaris team clutches, adjustable primary clutch weights, high perf. helix and spring in secondary clutch, 30" mud lites, heavy duty front and rear suspension springs, front and rear brush guards and with the suspension mods came 15" of ground clearance. Happy Trails man.

 

Just looking for bolt on mods. Riding style is pretty laid back, I do a lot of riding in Maine and lots of hills!

 

Well Rudy some good add-ons would be a slip on from Bikeman Performance or Aaen, with this exhaust you'll have to bye a jet kit from dynojet and install a K&N air filter for more air flow. If your in to the hills I would personally upgrade your tires and install a mild clutch kit but not to radical pending on the size of the tire upgrade. Have fun with the mods and keep in touch, Happy Trails my friend

 

Thanks for the info. Where is a good place to get clutch kits. And do they call this a "mild clutch"? Or is there a special name for this..

Not worried about installing all this, pretty handy but just dont know what to get.

 

Your best bet Rudy would be to call or look online for places like atv performance, polaris performance ect... I would strongly recommend bikeman performance, that's who sponsored my atv and there a lot of help. Ask for Jimmy and mention that you where speeking with me on this site and I'm sure he will be a lot of help to you. Chris at the Polaris dealer in Sudbury, Ontario Canada. Tell him that he know's who I am. The performance mods done to my atv are a little bit radical but work awsome, they do really nice work and there in the U.S. so shipping cost are minimal. If anymore ? let me know. Happy Trails to performance.
