I have a 1998 Polaris Sport 400. It has never been rebuilt and is starting to run alittle sick. I was wondering if a new topend kit would make it run almost like new. Also are there any good aftermarket performance upgrades that will make it noticeable faster? Thanks in advance.

 

Will someone please atleast tell me site with a list of upgrades for my 400 Sport?

 

A fresh topend will definately help. While you got it off you can get it ported (200$) Or you cuuld just install the new Wiesco and add a trail pipe and a clutch kit and be real happy. The mods available are STUUPENDOUS Dont forget a new belt and check clutch alignment [img]i/expressions/face-icon-small-happy.gif[/img]

Patience, here are a couple. www.aaenperformance.com, www.hotseatperformance.com, www.erlandsonperformance.com, www.rittercycle.com, lrdperformnace.com, www.hpd-inc.com.

There you are. And yes I would imagine that a new top end on an origonal 98 400 would wake it up depending on how much use its seen. good luck.

 

LOL guess we were posting at the same time.

 

Thanks everyone.
