Hey, Marc-

It's official! It's not a bug, it's a feature!

I pulled the alarm off yesterday, and the stutter is gone! I never would have suspected the little bastard.

I've upped the mains to 182/185 again, and aside from blipping the throttle at idle, the acceleration stumble is gone too.

Now that I can actually feel the power on top, I can finally start tuning for the proper main sizes.

I'll send you the numbers once I get the bugger dialed in.

Thanks again for all your help!

Steve

Persistent missing at high rpm?  Anti-Theft Alarms?

Regardless of main jet selected? All air correction plumbing is properly connected? - the bike still misses at full throttle / high rpm.

And you have an "alarm" installed???

Disconnect the alarm and retest.

As of October 24, 2001, there have been many reports of alarms causing high rpm misfiring. Disconnect the alarm and the problem goes away.
It can be present when you install the alarm, may start after a crash or sometimes,  just "occur".

Call the alarm company to discuss that with them!

Cheers -

Marc

Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


 
The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.

Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
