I believe your motor likes that supertrapp !!!! I want to see the noise level chart

It sure does. I'm going to entertain the Powroll exhaust for this race, mainly for the fact that it sounds awesome, lol. I will most likely run the open ended Supertrapp in the long term though. Interesting results for sure on the dyno

Not sure what compression your running . I know the higher the compression , less back pressure is required . powroll used to offer a 13.5 piston and we used to deck the head a little so all that compression and the very free flowing Powroll exhaust used to be the best combo back in the day . Cant take anything away from a supertrapp though , their great pipes !!!!
So all i'm saying is I think we might see different #s if powroll old school motor parts were used with that powroll pipe .

I have to agree; I think with a different motor setup that the results could be different. It's definitely a high end pipe designed for a Powroll built motor.

I'm running 12:1 compression, powroll's race cam, the 6mm Sparks stroker crank that I picked up from you, lightened flywheel, heavy port work, and a 30mm FCR carb. I am using standard sized valves though. I'm sure oversized valves would make a difference as well.
I have a Kerker and an old Yoshimura pipe for a 200x as well. Maybe I'll run those for comparison too. Gotta love having dyno access

Tat bike I pretty dang sweet looking for a 200x! I like it a lot and that front strut tower bar is damn cool looking too!

Here is a picture of it at the Battle at the Barn! Check out the tricked out 250r and Tri-z behind it as well.

I can't believe I missed this thread....jesus that is a beautiful bike xrider. I can't believe you also have a missile kit! Just plain awesome...so jealous. If you ever decide to sell that powroll exhaust keep me in mind . That exhaust and a finishline axle are all I am missing. I have been looking for one to purchase for a couple years now....those things are about as rare as it gets!

Duro power trail, I use the same one.



xrider's 200X is soo cool, I remember seeing it set up a couple different ways. Tough bike for sure!
