I have a set I can use right now. I know they have had problems with them cracking and from what I gather the newer versions have more mounting tabs. Anyway, If I drop the PSI to 125-135 wouldn't that be a little less vibration for the pipes? I also have a friend who will swap me his Factory Pipes(My old set I sold him) for the nice new set of Speedwerxs I have now. Anyway. I will also be running 46mm carbs. Any and ALL comments welcome.

You do have Speedwerx pipes on your 2001 right?

I run 3 gpr,s with speedwerx pipes have had no problems with them.you can run them with your setup except for one thing,your cdi will need to be reprogrammed for the speedwerx timing curves.btw i also run factory triples and have cracked three pipes so far,factory pipe has replaced all three free of charge except shipping,point is that factory triples do crack also.

talk to henry munoz, he runs speedwerx pipes, he knows all the tricks....

thanks for the plug Hop,

I'll help if I can. I've had the pipes running for a season and 1/2. nothing unusual to report. Make sure you clearance the screws that hold the front cowling as the vibration will drill a hole in the outer jacket. my latest thinking on the cracking is to inject hot water into the pipes instead of cold from the manifold, as far as compression, I have run the pipes with 135 compression. with a 13/19 it's fine.
