I don't know much about tuning Xchambers so if you guys could give me some useful info on how to tune one it would be deeply appreciated. Mine is a SBPXchamber.
How do you tune an Xchamber?

see i'm wondering cause now I can hit 32 easy sometimes 34 but today it fell off of the header and my bike shot up to 37 so I wanna know how to tune to achieve that power I got today.
I have the same pipe. My bike was running good before the xpipe, and ran even better after just slapping it on with no tuning. I couldn't tell any difference in the mixture.
Just curious, what type of bike is that you have?
That's cool, I like that model. I have a beach cruiser too. It's my first build. The Atomic BB
It looks awesome!! What speed do you get out of your bikes? Cause really my goal is to get as much speed out of my 44T sprocket before I switch to a 36T. I can reach 34MPH with no wind on a flat road. This is my bike just with a different intake and carb.

General wisdom on expansion pipes is that having a header pipe that is about 12" length is good for low to mid range power... Cutting it down (to under 12") helps with the high RPM power.

See I want to be able to cruise at 30-35 maybe faster, right now I can cruise easily at 25-26 without the engine wanting to jump off my bike.
I concur.. Especially when it's so easy to mount some of these things. Like the SBP T.P.General wisdom on expansion pipes is that having a header pipe that is about 12" length is good for low to mid range power... Cutting it down (to under 12") helps with the high RPM power.

Shortening the head pipe adds to your top speed, but takes from your torque.
Lengthening your stinger adds to your top speed, but takes away from your torque.

Wow I didn't think the stinger would do anything I'll try it cause I've welded the the header pipes together already.
someone needs to make a sticky on expansion chambers. not out of this thread though. I'm talking about a compilation of useful accurate info on the subject. HINT HINT MODS.
I had a brain storm today. Those of you who mess with rc cars know about buku pipes for them, my thoughts are could you put a spring in the stinger so it pushes the cap back to the Xchamber and with the RPMs it gets pushed forward by exhaust thus adjusting itself, point being, you get better torque and top end. What are your guys thoughts on this, would it work. I've got the idea on how to make it I just want to see if its worth the try.
