I'm sorry that this news comes so late in your build but I found a guy (a brit bike racing Canadian) at www.britgaskets.com that makes some cool gaskets out of carbon fiber/NBR binder. They look great and I'm trying them out on the 750 that I'm doing now. They sure seem to beat the hell out of those OE style paper gaskets that the brits are always offering up. Supposedly these gaskets have cured many of the leaking issues AND they are supposed to be reusable if they are applied correctly from the start. Like I said earlier, the manufacturer is a racer and pulls his stuff apart a lot. I'll let you guys know how they work out. The only drawback is that he produces stuff mostly from requests so he doesn't have a full line for every size brit engine. But he does take suggestions and if enough people want something, he'll do it.Flyin' Dutchman said:
This is purely my opinion but I have the feeling that some of your lack of power is a combo of the short pipes and the mag.Flyin' Dutchman said:
Mags look cool and I've heard good things about them in racing situations but I don't think they are versatile enough for mainly street performace apps. That's why I'm a fan of the Boyer. I think on an engine where you have to synchronize two carbs and two plugs to deliver and fire dependably, EI helps a lot.
On the exhaust side, there was a really good post on the HAMB a while back where a bunch of guys were addressing pipe lenght and style versus performance but I can't remember who started it so it might take some in depth searching. I think with displacement as small as 600-800 cc, coupled with short intake paths and EXTREMELY short exhaust paths that one needs some length and back pressure in the exhaust to help 'tune' it.
I'll join in the request for info by asking about valve size and compression. Anybody increasing valve size and to what? And what compression are you able to get away with while staying cool and using the sad pump gas we get now?Flyin' Dutchman said:
