Nice #s is that motor in your bike frame and wheel setup or is that his frame and his wheel and megaphone system
What exhaust are you runnning? I had to go with a marks 4 into 2 into 1 system to get the full performance out of my motor do yourself a favor a re dyno it after you get it all together i bet you find the #s a lil lower,but you can tune it to your setup.
I went with the ufo quadzilla
How are the Quadzilla's at normal cruising? Loud? To loud for a comfortable ride?
Won't know for a little bit still rebuilding
Would my 1540cc likely make more power with a 4-2-1 or 4-1?
How much more I wonder?
It's got the early UFO 4-2-2 on it now.
Does anyone still make a true 4-1?
Or is it just 4-2-1's now?
The 4-1's I've seen had ground clearance issues with the collector.
No Dyno numbers yet either, hoping for 170.....
