Got the tap out (with a Jim's guide) and re-tapped the hole. Good to go now but after 20 miles I'm losing nuts. I'm gonna pull it all off tonight and re-assemble it. What's the order of operations advice? Loosely from the front head, down, from the rear head, down...again and again? Oh, yeah, the dealership convinced the me the flat exhaust gaskets were better than the tapered ones. I'm having a feeling that's not the case. Thoughts? Good talk, Brent | ||

Jims guide and carbide drillbits? That'll remove a tap? Thats good to know! You have a tuber, right? Replace your front exhaust mount with the updated (upside down Y looking part). Also retorque after the first few heat cycles. | ||

I've always had the best luck by first tightening the header bolts, then the muffler, and the collector last (as that mount, if it is the newest version, is the only component with some adjustment built in). That is the most stress free mounting I've been able to achieve. With the flat gaskets, typically they seal best with 2 into 2 exhaust systems with no connecting pipes. Although they can potentially make more power than the tapered gaskets (if those tapered gaskets are crushed too much, which happens often), I've ALWAYS had them either leak right off or blow out eventually. | ||

The Buell headers with swelled ends work best with the tapered gaskets. Careful install and no overtorquing is the word on these. The flat gaskets work best for headers that use a larger pipe welded onto the header pipe as the retaining ring stop. Sometimes it's a good idea to put two of them in, though. Alternately, if you put TWO retaining rings on, it will pull the face of the header in closer to the gasket for a better seal. Some experimentation is needed to figure out which works best with the header you have. Al | ||

Speaking of swelled header ends. I had trouble with mine last year. The retaining ring, once seated in the header clamp and all bolted up tight, the header kept popping loose and drifting out of the clamp. The solution was to carefully weld some spots onto the swelled area on the header end so as the retaining ring had something to grip onto. The swelled end is pretty nasty really and not the best solution to mount the headers into the head with. Buell tube frame exhausts have always been a pain in the arse. Rocket |
