Matt, a lot of guys will be happy in the spring for the accurate tuning info and tweaking you're doing now!

Stretched the pipe by 3/8" and that, combined with leaner low end, eliminated the jumpiness at 1/3 throttle.

This is a big development. I was kinda worried about that because mine jumped pretty big thereabouts.

the distance from the plug CL to the end of the pipe (not including the stinger) is 33 1/2" straight line. That's approximately 27 1/2" plug to baffle.

Very handy number, so we don't have to stick something down the pipe to figure out where the baffle is.

Top end rpm is higher than my ear perceived originally...I tached it at 8200 after the changes. Pretty terrific!! Throttle response is now about as linear as anything I've played with before and with the amoun

The thorobred can be tamed. Excellent developments.
