Just shy of 100 mph:

I've had mine up to 85 where upon I experienced immediate multiple orgasms in such rapid succession, the fear of passing out from which,  precluded me from determining further whether I or the bike had much left to give.  

Huh, the Devil made me do it! Post #666  

Hi Bill

Sorry for such a delayed reply.....Yes! my s40 brand new and is stock except for the hartmann mod to the muffler.....
In an other post I initiated...."soot when blipped" i have said that my bike soots when it is blipped(even when warm) to me it seems that its rich. I say this because when the throttle is blipped I see soot which means that there is vacuum in the carburetor and not enough air comes in as fuel is sucked......it DAHHHH's on decleration and phuffs randomly during gear changes......I have done 93 mph sitting straight the front end felt light and there was a buzz in the handles....it got to 85 mph immediately and then the remaining 8mph followed somewhat slowly.....
I think the factory might have changed jets....could they???
I will try it this week end without the airfilter to see whether the soot vanishes/dwindles or remains there.....

How did you verify the speed?
