Ok people which pipes seem to be working the best on these babies? Which air filter setups are working best? What jet settings are you using with your setups? I'm a newby to working on 4 strokes. Thanks.

 

i know what works for me.
heres to much info on hmf http://www.hmfengineering.com/forums/index.php
i have a test comparison article some were on different pipes ,i think is on 6 different pipes , it will take a little time to find it.

 

the dr d exhaust system works good for me...but i think that they are all pretty good and it just comes down to personal preference. if your looking for more reasons,..then im sure there are plenty of dyno reports and comparisons out there....sound and looks may have an impact on your decision as well...happy hunting and good luck in your choice.[img]i/expressions/face-icon-small-smile.gif[/img]

 

ive heard good things about the Rossier pipes, built in a town about 20 miles from me..

What are the power gain differences between a slip on pipe setup and a full system exhaust?

 

Is anyone running the ESR Pro Series Thumper pipe and air box eliminator kit? If so how does it perform? I know their 2 stroke pipes are great, had one on my 250R.
