Hey Steve,
Many thanks for the info, your idle rpm seems a bit low, I was under the impression the the JJ1800 idles at ~35,000rpm, I stand corrected though! The temps seem quite low too, Jet-Joe quotes something up in the 630c range!? Maybe your bi-furcated pipe has something to do with it? The cooler the better, to a certain extent I imagine!

More questions if you don't mind, would you know the tail pipe outlet diameter? Also the outer diameter of the tail pipe mounting flange, the reason I ask is that I wish to manufacture a new 316SS tail pipe for it and need to know the approximate sizes etc. so I can order the materials asap, just trying to save a little time.

Thanks once again for your time,

Cheers from Sunny Sydney,

Smithy.
