Hey Guys, I'm a new member here but I've been riding my 97 M2 for about 5 years now. It has most of the modifications available for it but now I'm on to my 3rd header and I'm just curious what some of you guys think. I recently bought a stainless header from Al at American Sport Bike and I had to modify the link pipe to go from the 2.5" collector to the 2" inlet on the V&H. I haven't been able to ride yet and I'm curious what you guys think, will that be a problem with reducing the flow?

Dutch x1,
Thank you for the offer, probably only easier for you though... I just bought this header and it would have been a sort of round about way to solve my exhaust dilemma. Do i guess correctly Dutch that you're located in Europe?

i still run 2" stock stainless header & an australian made stainless 2" sport muffler. but i have two spare head pipes one is 2.5" with EFI bung on rear pipe the other is 2" also with a Bung for EFI i'm still on original head pipe 80,000k up might just be lucky. i'm going to see how fast i can get trap speed 1/4 mile with 2" head pipe stock m2 motor carbon air cleaner lightning ignition module & 44cv ( bob woods 43.5 rebel carb ) SE cv44 manifold
only reason i used the carb is i had it laying around and the stock jetted cv40 carb that came with bike was very lean. now it's runing nice & gets better gas mileage too. i'll check AFR on dyno just to make sure its right. i'm going to try to get 112mph trap speed 1/4 mile with 2" collector stock M2 motor.

Hey Lake, thanks for the info. My problems started when my top end started leaking and I got a little carried away with the rebuild. I thought if I have to rebuild it I might as well go BIG. So, after an NHRS 1250 kit, Andrews cams, a Zippers pushrod kit, and n S&S Super E carb. My mech and I thought we should beef up the top Eng isolater. We modified a tractor isolater (i.e. HD) and within 200 miles it tore, leaving the eng vibrating a little more than OEM. Thus the cracked pipes.

Yea, your screen name is a pretty good hint. A very good buddy of mine lives over there, Spijkenisse. From what I've seen there is a great bike scene in the Netherlands.

Zedhead47 i think the Stenzel bar could possibly help your front issolator issue as it supports the issolators from forward to rear movement. made a difference to how my M2 handles. very happy with it.

Lakes thanks for the input. After reading your post I've read up on this Stenzel bar you're talking about, and it seems like a pretty good product. I'm wondering if it would still be necessary after going to the upgraded front isolater, and the billet motor mount? $$$ is a little scarce right now.
