Send it to me ... I'll fix it most likely free or cheap there is 2 good diaphragms left in my friends carb rack... might be time to buy the whole rack ... we seem to be eating diaphragms ...
Cool.

Yup ... was your bike doing somehting like what that JCH guys bike is doing ... basically no rev past 6K in 5th or 6th ...
BTW man FWIW ... that symptom totally sounds like ripped diaphragm to me ... not butterfly shaft issue, but we'll see maybe similar symptoms ...
Scratch we wait your call...
Cool.

Nah, it just hung up mechanically, didn't affect performance at all.

Cool.

Well Srinath, I'm going tot ake the bike out for a run this weekend weather permitting and to see if I can fine tune my perceptions of whats happening. Then I'm picking up a clymers from a friend and I'll be looking ot over to see if I can take the diaphragm out...  Will this be a crack or line that is visible to the naked eye?

Post the symptoms ... but really anyhitng bigger than a tiny little hair sized rip is going to make it lousy ... Post the symptoms ... I sorta forgot ... but small rip is enough to make you miserable.
Cool.

75 MPH max speed.    Acceleration fine up to that point, which is pretty much right at 6k RPM at 5th and 6th gear.    If I back off the throttle a little I gain maybe 5 mph, but then it tops out again.

OK that will be a tiny tiny rip in 1 diaphragm ...
Cool.
Srinath.
