Now that was fun - 2 smoker coming on cam and mifiring on over runs, with a bit of Asian accent to boot! I don't do that in public no more, just the 4 stroke run up sounds till my lips or throat over rev. Doing it in metal shed just ain't quite as neat as in a tunnel of course. : )

Dare ya to risk mimicking you know who till it Howls!

My goodness the audio is horrible, but that was a great race. Mid Ohio (one of my favorite tracks) - I took off from the 2nd wave and caught and passed everyone, including the big GPZ kawis in the open Formula class who gridded in front of me.

At 3:37 you get a glimpse of legendary frame guru Tony Foale in white leathers, and at about 4:35 the leader on an aforementioned GPZ comes into view, and that's all I needed. He had the power on the straights, but I wailed on him in the turns.

This upcoming season I have a great camera and better placement out of the wind. Hope to get some good vids with good sound.

Bad wind blast audio or not - above is music to my ears!
Kenny says something his peg pogo's tires off so he just pushes off knee to pick it back up into traction and carries on>>>>

Gday Steve, thanks for that vid, no wind but still a BLAST, my face is aching from the grin it produced. Truly a beautiful sound that, one Kenny Cummings Norton on song at full noise! Mmm... good numbers it says, Id like to know what they were? Keep up the good work Ken, you have followers all around the world!

Yeah man Foxy, grinning till my face aches! Its almost hard to be around Kenny right before a heat and of course after he's won a round, he's beaming so intensely.
Some part of the face ache is from gritting teeth to take what he and others do to them poor ole elastic engines. I'd guess Kenny's bike is good for at least 140 mph. I once heard Ms Peel more than peg her tach needle inside a 20x40 tin shed, about like a whole orchestra on amps being dropped through the roof. Rev limiter from now on thank you on any hot rod.
 
As your bike is easily able to top 160mph, and handles better than modern Jap sportsbikes, is it not time for the Hobbit Norton to start to become involved in US classic racing? With removal of the road equipment, and fitting modern suspension in place the OE 1960's stuff, then surely the bike would be a serious contender for MotoGP racing, and would no doubt create an awful lot of interest.

Alas, there are homologation issues to be sorted out...
 
Well, for Hobot's Commando to be hitting the top speeds he claims, he has to have his Druin blower hooked up.

And, he has stated that these speeds are attained with a single 34mm Mikuni flowing it all.

With all due respect to Hobot, I just have a lot of trouble believing these claims.

From my own 40 year history with seven Commandos including a ported, rocker arm lightened, Dr. Blair 2 into 1 into two exhaust Combat, I don't ever recall seeing the speedometer exceed 115mph, and this at sea level and within months of the bike and motor being brand new, and me weighing all of 135 pounds back then.

Hobot says his single Mikuni is every bit as good flowing or apparently better, than a twin carb set up. Everyone, including top speed racers, says no way a single carb can flow anywhere near as well as a twin.

Regardless, I don't know anything about blowers, so maybe Hobot's blower even with a single carb, can get his bike to see 130-140mph.

In theory, are these top end speeds possible with a single carb? I think he said his gearing was quite normal, maybe a 21 tooth front sprocket?
 
With a blower a 34mm carb can easily flow enough air to make the power needed. It would likely require a fuel pump to keep the bowl full of fuel. Jim
 
Is there a point of velosity to which surface adhesion could be reduced or even eliminated? I guess what I am asking is, might this bike actually fly by the thrust of the exhaust? Maybe by changing the direction of the peashooters and some minor faring applications? I have a feeling it might have been attempted in the misty mountain air of the Ozarks.

As long as the exhaust looks like this it might fly.

Fact is I don't understand the conflict of Peel's gear ratio's and tach reading compared to the fun and games I played with friendly to VERY F--KING ANGERY
Squids on 600's I could out accelerate to speed and could not be left behind in longish straights. Only special feature Peel had was a steel flywheel and 2-1-mega. She was a bit lighter than standard Cdo - about 350 lb + me 165 lb.

Peel was my first Norton rebuild so was shocked how potent she was in her best combo. I was so looking forward to even meaner power by putting on the new dual 32 Amals and it dropped top end power and climb to top end power after 4500 rpm or so. Then put on the lost to M.A.P Cycle shop in processing for 1.5 year Combat head with Dreer 6mm K/W valve/spring kit - thinking would bring back the lost power of dual Amals but bogged her down to normal Cdo power that would not run out under me nor able to play with hot moderns except in corners of course. Peel had over rev stuck throttle event just before I got around to putting her back to mere break in set up. So no objective data by GPS or digital speedo to offer by video viewing.

I also think that the mis-match lip of 34 mm carb on 32 mm manifold to 30mm head with rough gasket edges into the air path had something to do with extra spunk.

I also did experiment of Dual Amals vs Single Miki mouse carb on pure factory Combat Trixie to feel the Amals were more responsive up through hi mid range but 34 Miki carb pulled better beyond that up to 110 mph when I chickened out to wait to go much faster, as not thrilling pull like Peel, just fear I'd lose control or blow up engine. I'm not sure if my factory Combat Trixie can pull 120 and may never find out as she's in same obsolete league as others to have a snow balls chance in hell to even keep up with my wimpy SV650 let alone hot 600's out for a really good time. I could not keep up with angry 600's on my SV650 in opens either. SV650 was as potent a puller by peddling gears as Peel up to ~70 then Peel could leave it behind rather quickly.

My findings are a single bigger carb can flow more mix to 2 jugs than two smaller carbs each feeding only one jug each. Two smaller carbs are better for normal sane legal-ish riding as a bit better low-mid range response but with a bit more effort d/t two slide springs to over come. For sane riding and thrills I like pure factory Norton Combat best with dual Amals and points on two peashooters, as long as I'm careful in sweepers to hold speed/load down like every one else. Factory Combat was so easy and pleasant to operate I feel its what I will end up with till I die. Peel on the other hand tempted me no end to tease the hottest bikes/pilots out there into most dangerous conditions and leave em behind in refreshing glee no pilot strain or skill hardly needed. This is not freeway like places but twisty curvy up and downs narrow secondary roads.

I timed a couple of max runs to and from work on level valley hwy section to steep curvy sections to loose and steep Gravel section of 19.5 miles. SV650 19 min, Ms Peel 17 min. Never again though as too freak out risky d/t blinds.

I have the standard head, 2-1-mega and 34 Miki to put on Trixie someday to reproduce Peel set up to see if just a fantasy fluke or something to it.

But you'all are so concentrated on top speed, pashaw that ain't real life adventure I seek and don't mean much if they have to slow down to crawls
just to take a mild turn while Peel didn't slow up but accelerated in glee so they needed all their power and speed to regain lost ground if long enough straight they could make it up in time hehehe. Main pisser to me was getting passed
in straights getting up to speed after a rest stop and heading out into the good stuff again, by 900's and above. Also pissed me off after coming out turns way head to get passed by 900s-1200's before the next turn a 100 yds ahead, where i could run right back up their tail lights but they had clear shot into next open ahead of me so left me behind till they slowed again for the next real turn. New Peel will not have that hindrance.

Anyone can buy more power and its sure needed to play hot games but my wonderment is with the insane stick and handling of tri links to put down more power, way more power when leaned a bit. Stay tuned and see if I go down in smoke or in flaming trails off into the sunset : ) Basic engine is almost done after 5 yr work up. i left online engine calculator and conservative data to plug in for idea what's in store. i do want to pull like dragster to at least 160.

Hehe, I'm a student of Richardo research so instead of throwing in more fuel Peel gets water sprayed in. Ricardo showed its best to reduce hydrocarbon fuel and add more water -up to 50% when detonation spikes show up as power drops just throwing more fuel in to avoid detonation. Running low on fuel flow may be good for Ms Peel for max power level.

Lake injector is just open tube facing up with a half round needle in it, the extra combustion pressure fluid gets fed in by 40 PSI regulated from 100 PSI swing arm. It would be simple to also pressurize fuel tank for more out flow if needed. Rather less mass than another pump too.

I had long educational talk with the out umbrageous supercharged dragster at Barbers, the one with like 2 ft wide slick. Hehe no fancy computer controlled injectors involved just plain old school pressure flow.

Actually there is something to aiming exhaust plume as Tony Foale and others have covered this. I do think it helped Peel go as fast as she did naked as a J-Bird.

Peel's engine did have one other feature - EVERYTHING that turned or slid was dry friction coated by Tungsten Dioxide. Might of helped hi rpm power lose?

If MotoGp races were won on the basis of BS, then it seems that Hobot would have a good chance of becoming world champion!

That gives me a GREAT idea!

"Moto BS" champion.

(of course we'll have to start a new thread in the "Anything Else" section)

Come up with your best story, should have some nearly plausible tech facts, maybe some amazing dyno and flow charts with extrapolated curves based on your own personal beliefs.

Photoshopped pictures will be accepted as fact.

Additional details involving animals, women and alcoholic beverages should be expected.are good for extra points.

Cool team names and sponsors will earn extra points.

Descriptions of amazing race feats throughout the season

We'll let the thread run all year, then crown the champion.

EVERYONE CAN ENTER!
