clueless??? you'll get that from them,, any company that takes great pipes like the old 650 w/cats and builds a set claiming''trail smokin torque'' at an rpm 300 LOWER than stockers and lose hp is just that, clueless!

I ran BM twins on my 93 550 carb, mild porting, shaved heads, advanced timing, dial adjust and some clutching, that sled would outrun stock 700's. Anyhow I'll see if I can find some of my old clutching and jetting notes.
It should be slightly leaner with the twins but if that is the only engine mod you should be safe.

I thought BM only made pipes for the 93 580 Z, not the 550?

ottawacats/Vince, whatever you could find would be great!
