Lengthen the pipe to approximately 15" to the high point of the pipe, measured from the glow plug, straight line.

Good luck

That should be pretty hard on the Razors Edge isn't it?? I'm personally a bit more conservative than that...

I was tuning an AR today...I settled on 16.7" from the glow plug to the High point on a Hatori 650, Turning 10,200 RPM's on a 12x12 APC, PowerMaster 20/20 fuel and an OS#8 plug...(Just breaking in)

Was running one of my std LS's Saturday and got the same length(16.7) on the Hatori 650...It's turning a 12x10 APC @ 10,300 RPM...

Some of threads I've researched recently the guys were running the Hatori 650's longer than that (17-20 inches) with the YS 61LS...

Sorry to contradict your expertise...I probably normally wouldn't ...But I just did it today...So I thought I'd share my experience...

Have Fun...

Chuck

P.S. I want a Summitt III also...
