lcrken said:Almost, but not quite. I've run my 750 Commando-engined featherbed-framed bike at both El Mirage dry lake and Bonneville salt flats, and have timing slips to verify the numbers. Best speed was at Bonneville in 2001 at 131.113 mph. That was the class record for a while, but eventually someone bumped it up significantly. The bike had no fairing or other streamlining. It was as I had raced it with AHRMA, and made an honest 62 horsepower at the rear wheel (at sea level) on the AMI dyno at Daytona. Now there's an honest-to-goodness real data point for you. It was noticeably faster at sea level, and tripped the AMA radar gun at Daytona at 141 mph in 1985. With all the stronger bottom end parts available today, and using the improved tuning technology we have now, I'm sure you could build a 750 with 80 rwhp that would turn much better times. But it isn't going to be cheap.

daveh said:Ken, 141 mph at Daytona from a 750 with 62 hp would appear to undermine some of the wilder performance claims for standard street Commandos. Do you think there was more to come if you had a longer straight and higher gearing? Was the bike unfaired, as at Bonneville?
lcrken said:...At the same event, I was pitted near was a guy from Florida racing an un-faired Commando with a 920 engine who was doing quite well. His name was Dwayne something. He was a well-known Florida Norton tuner and racer, but I can't recall his last name right now. He was leading his class and looked to win, when he was black flagged because his rear brake caliper bracket had failed, and the caliper was hanging down. He thought they should have let him keep going, and was really mad about it. I talked to him quite a bit during the week, and he said he had been timed at just over 150 mph. From watching him run, I could believe his numbers, but have no records to prove it. His engine had all the trick tuning bits for the time, and he had spent a lot of time in his shop with flow bench and dyno developing Nortons. He ran without a fairing because he said it didn't add anything until over 150 mph or so. He said he had tried fairings on the bike, and it wasn't any faster with them. He was an interesting guy.

And finally must mention the late Dwayne Williams of Florida USA who ported a couple of Triumph heads for me. He was an acknowledged Norton tuner who managed a recorded 148 mph thru' the speed trap at Daytona on his 850 Norton in the late 70's and was written-up in Classic Bike I believe it was. Some folks now dispute the 148mph but his Nortons were undeniably fast!
I don't know if you had ever raced with Mike Smith of Michigan who said that 140 was it for top speed for the commando down hill with the wind.
hobot said:Carbonfiber I look forward to your energy brusts now. What's your issue with Mikes reaction to a stock 850 + Drouin boost? He's got the old dual belt drive and his success was prior to my decision to hunt down a Drouin as he sold me down the road of no return. Been yrs since last contact but his email there to ping him.
Wonder if I'm even up for it on a rather lighter better handling Commando. I get to states where my throttle wrist just over rides my fear sense, yes it hurts toes nails to teeth roots an instant to pass through that transition then is flabbergastingly wonderful. What current minumal level mordern you think might be the match of future Ms Peel? I'm pensive about the SR1000 and new Ninja with more performance quirks they need more digital brains than pilots can handle.
What ever your opinion, mine is Ms Peel is just fun wasted failed effort if not spanking these elites in conditions that only allow 150 mph or so in the opens.
Seriously would you not like to live in such a high state of fantasy on your Commando. Off to crusty snow pack see ya
