I have a 400ex and am wondering why everyone wants so much for porting and polishing.I have been qouted $400 from dealers and $700 for port polish and bigger valves.Is it worth it or any suggestions.

 

Call Swain Atv at Sikeston Missouri. JD is excellent at his work and he is a college grad. at techincal school. He knows his stuff. Port and Polish costs $225. You won't be dissapointed.

 

hey, thanks for the tip i will give them a try.Does anybody else know who will do engine mods right and reasonable.

 

I would highly recommend GT Thunder. They Race ported my 400 and WOW. The porting was $200 and the polishing, I can't remember, but my total was under $300. They have a web site which explains all the work they do and and even have the dynos to prove it. Fast Turn around!

This link is for the 400EX pipe shootout, but just look for the home icon.

 

I will try the web site , how do you like the works shocks. Im thinking of triple rate AT's with remote res. and ultracross rear.

 

I love my shocks! My shocks let me do a lot more air time without bottoming out. I would recommend them, and if you don't like them, you can change them to TCS shocks for under $300.
