Why would you file your plugs?

Revving the hell out of the bike when there is no load on it is not good. If you just bring it up to redline a FEW times (not keeping it there) you will be ok.

Nah, shouldn't hurt anything, cept your eardrums. Drag and GP bikes are run without mufflers all the time. Residents may complain cause it's gonna be loud as hell. The can pictured is half size and it's louuuuud.

This might be helpful, this guy is a bike mechanic:

Quote:
"Well on any motor there is a such thing as tunable exhaust. Basically meaning you can do whatever as long as the appropriate adjustments are made. The exhaust uses sound waves to cary the exhaust out of the chamber at the appropriate volume and the appropriate speed. That being said how far do you what to go/ willing to spend/ what do you whant out of it. Are you going to weld somthing up your self?

Now taking the mid pipe off and running strait headers can be done with proper adjustments to the intake and fuel track. I have actually seen this produce a lot of power if done right, but includes valve timing (cams), ign. timing, and alternative fuels to keep detination at bay. Without these mods the motor will fry valves in stock form. Not good!

Those moto and superbike exhausts are super flowing for huge air fuel numbers. The Turbo as you probably know is just a recycler thus builds top pressure. So no need for back pressure.

All in all just remember the length and width of that performance pipe is proven to work and any changes to that will affect the porformance of said motor.

Hope this helps, and let me know if you need anything else or don't understand me"

Look . . . the people you are after are the people you depend on. We cook your meals, we haul your trash, we connect your calls, we drive your ambulances, we guard you while you sleep. Do not fu|< with us.

What kind of project is this?? Who can flood their bike first while going deaf? I bet you must like expensive repairs

This'll reduce backpressure, less backpressure leans or richens the mix? If it richens you'd be cool but have to clean the plugs right? And if it leans you might burn piston-heads?
