I have no idea what kind of pipe this is, but I want to run it on a stock Yamaha. Can anyone tell me what it is and how long of flex should I run with it? The only identifying marks I can find is a 2 . welded into it near the outlet. Here are a couple of photos:





Thanks for your help!
 
I would start at the factory setting of 10.5 from the edge of the piston. Looks like a PITTS pipe. Really similar to the G.E.M pipe. What is the diameter of the fattest part of the pipe?

I agree with JTRACER44, it is an old RLV2. we referred to them as the "two dot". We ran them around 9 3/4 for sprint racing.....Think I still have one in my pile of pipes.
 
It's been way over 3 years of broken promises kindly mail me the buller aero chassis stuff I paid for back then. I've been very quiet & patient. I paid for it & it's mine. Also the PCR I paid you for does not have all PCR guts. If I was told upfront that would have been a different. There's no possible excuse for Adams 2011 until now un-delivered or finding out what was inside upon rebuild years later.

I forgot all about this thread! Vintagequest, I went with 9 3/4" of header and it ran pretty good at Avon, NY. I didn't try any other lengths. By the time I got the kart handling the way I wanted and then got my act together driving - it's been 27 years since the last time I drove a kart - the weekend was over. Unfortunately that's the only time I've raced it. I did manage to lead my second heat right up until about a lap and a half to go, and went wide in a turn letting the second place guy get by me, so I settled for second. Not bad for an old fart!

Gentlemen: I know I'm a new guy here, but would you fellows mind settling your dispute via personal message rather than use my thread? Thank you.
