Jerry, at the risk of losing GMC some business, did you know Hughs sell a Pomeroy pipe, built to specs JP used. I've ridden an M120 w such a pipe & it was a jet. It got the holeshot at the Cheeribah Nats in 2000 (not w me on board). But it doesn't have 3-stage/tapered header like GMC's, so one wonders what his pipes would do! (ie how much quicker??)

I believe tapered headers aren't legal for AHRMA's equivalent to pre '75. The Pomeroy would be just what Jerry needs...I seem to recall Circle F or one of the other American pipemakers produce a Pomeroy pipe as well. If only I could remember where I saw it.

Thanks guys already talking to Geoff Morris about making sure the pipe "looks right" Going up to see him in a couple of weeks. He's mentioned maybe modifying the frame with the extra swing arm pivot plate. Having a think about that at the moment. JC obviously saw the video. What about you Firko? Jerry

Ray Smith (40) used a GMC pipe to keep the kids honest in the 250 class at Broadford last year.
Although, now that I think about it, Ray does share some resemblance to Kenny Zahrt.
Is that how Jerry was able to ring Kenny? The phone call didn’t leave Vic.


But yes, for Jerry to do this replica he won’t want one of my normal spec chambers, and we have discussed this already.
Jerry, if the Hughes pipe looks right for you then go for it.
Can’t watch that video myself until next month, this months download quota is well gone.

The Hughs pipe I've seen is diff to the 73 pipe in the header. Instead of one large radius bend it has two smaller radius bends, like the 360 pipe
