Anyone willing to enter their Commando in a straight line speed test? That would settle the matter!

I would, But..........
they don't make timing equipment capable of accurately clocking my bike as it goes SO fast!

also, it uses half as much fuel as yours, weighs nearly nothing, and only cost me a couple of hundred buck to build!
Water injection? PFFFT! everyone knows that pressurized sunlight is the only way to make any REAL power.
 
The number of replies to this thread has exceeded the formerly famous Result of Trispark thread.



Dubious distinction or not.

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!

Looking at his past "track" record Hobot has it in the bag.....................lol
 
Dear sirs, the Texas Mile is part of Ms Peels plans. Ride out there and unload the cargo and switch a sprocket then see how it goes. Will keep the bags on as aero aids. Pikes Peak is another trip she might be allowed to enter after unloading and undressing so fairing and bags don't hinder the leans. I'm rather depressed its being paved over. Oh well sharpest steepest rough tarmac is how i discovered Peel wonders and only places to troll for them plastic appliance corner cripples. Hope to save up after Peel is done for a 'run what ya brung' salt time trial for pecking order in thin air on loose surface both naked and with cargo touring weather protection on. I don't expect to have the fastest or quickest old motorcycle in the world just the funnest without a single feature that isolates pilot from direct intuitionist control. You already know my brain ain't up to it, but my glands and spinal cord/brain stem are, which freaks my slow rational brain out no end too.

Place your bets on what you think Peel will be limited to in 1/4 mile ET's and top speed run and Barbers' track average. Here's tops at Barber's so far.

Well I think I may know whats going on here? LOL, I recently purchased a rebuilt speedo for my 75 MkIII off E-bay that I was told was in great shape and had been converted from a T 160 Triumph. (I needed the one with blue and white Norton Villers arrow on it) Not knowing that there was anything to worry about as far as ratio goes I put it on, WOW my bike just picked up some serious speed. I think it may be able to reach some of these speeds now. :roll: Maybe Hobot has the wrong ratio speedo on? Just a thought. Does anyone know the proper ratio for a T 160 Triumph speedo? I only paid $36.00 plus shipping and the thing is near perfect condition. Live and learn.
 
Gosh, I wish I'd had one of these 160+mph Commandos in the mid 70s. I'm sure I'd have taught those TZ750 guys a lesson or two on the racetrack...
 
Yep ole hobot is aware of speedo errors even GPS errors d/ slope of travel. So was one reason I'd ask the hot shots on hot bikes to have a hi speed run in safe section to compare speedo readings. Ms Peel had new speedo and drive and read about dead on steady, my cars 2-mph too high and faster bikes about 3 mph over actual speed. Alas ole Smiths' will not keep up with new Peel so hunting something up to the task. I may put one on each wheel as their speeds vary a good bit on Peel. Its also gives me a sense of how spun out I am before or in a turn as can't always hear or feel it so helps me to fly by instrument on places I've monitored limits.

All's I can say is 130 indicated on a number good kit moderns wasn't enough to catch Peel. Pissed my off they would not run on up to match speeds. Peel never did get passed on top end, not that other bikes couldn't top her, just no one willing to go that fast I guess into the conditions ahead. Peel got passed on slower drag races from dead starts and after corners into opens in the 60-90 mph zone or when I slowed up for blinds I just couldn't face w/o good reserves anymore.

See if you can find the specs on proper functioning Smith speedo. I came across it once and surprised it said within 1 mph expected.

Sprints and top speed are sure fun and common goals to measure and seek but that's not what I'm so intent on, to me that's just pleasant side effects of the handling and performance needed to do slower stunt games I like better to do on and off pavement. Most crazy thing I can feel Peel wanting-inviting me to do is a side ways barrel roll to land on tires and carry on. Now that scares me
having almost done it a few times by accident, thinking hm with a bit more power and lean, this wouldn't hurt like its about too.

Here's example of phase five handling which I had to learn on P!! that didn't lean and do routinely on Gravel Climb outs with curves. I practice it by in lane zig zags till tires fling off surface. I just want to do it in road racing conditions over the ton now. Its pretty easy actually once tire lit up so real trick to me is not to spin to smoke just max slippage for max acceleration w/o hesitation.

I'm picking up my first Commando next weekend and after reading this thread I'm worried about not being prepared as my current ride is only an injected 900cc Ducati Super Sport. It only develops between 50 and 80 HP depending on which magazines you read... :roll:
You walk home here if you get pinged doing over 130 KMPH.....lets see thats 180 x 5 / 8 + 212 ....whatever.....about 80.
How do I control such a powerful machine....especially if its like most Pommy ( limey) bikes and the speedo is all over the place... :wink:

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.

Nice comparison. I had both fast Commando racers and a late monoshock TZ750 back in the '80s. Loved them both, but talk about apples and oranges. The TZ actually felt like it handled worse than my 920 PR, but that was because it had twice as much horsepower, and the chassis and tires at the time just weren't up to it, at least at my level of riding skill. Seemed to work OK for KR, though. And definitely way, way faster than any Commando I've ever had or seen.

Gee whiz, I just gotta weigh in on this speed thing.

I named my Commando "Fred" and it has run at a timed 148mph with only ONE Amal carb hooked up.

I shudder to think what I could have run with both carbs sucking away!

Now, me an Fred were running hot against three moderns one dark night, you know, Ducatis and GXSRs and exotics like that.

I admit I had just a little trouble keeping even with them up to 140, but then I just blew them away in the high speed corners.

This is always where my superior skill can't be matched by them crazy young studs. I am just too damn good!

LOL!

Now, mind you when I say the "timed" speed was 148, well that was what the moderns told me they saw on their speedos.

And them guys would never, ever make up some stuff just to spoof someone like me. No sir!

If they said 148, well then YES, I was doing 148!


More stories about me and Fred blowing away moderns tomorrow night.

Stay tuned!
 
Commando Top Speed? (2010)


Now who says it can't be done and who says you need a Drouin to do 150 :?:

Alrighty I'm giggling on comments as camps resolve into positive, negative and neutral. Ain't no 160 mph daily road going Commando I know of, so far. It takes me too much skill and nerve to press unlinked 45 hp Commandos to limits to be any fun. So my respects to any who do. Would love hearing all about the phenomena of how Cdo's feel-behave in their infamous 'hinged handling onset and recovery.

I flash back all the time on P!! and Peel events I've described but my heart is set on the closer future. Every now and then I pull up this 2002 private mail that leaves me tingling to keep Peel progressing.

Commando Top Speed? (2010)


Well Steve, things were happening so fast I was shifting at a perceived
5500rpm but it was spinning up so fast I bet it was more like 6000rpm by the
time the shift took place(a pause for huge grin here). I don't think you
need to spin it up more than that for the street. I would say Mr. Owen is
spot on at 6200rpm. I looked at the plugs and they look perfect. They were
cold plugs from my BSA. (N5C Champions). I may just have to take it out
again first thing now that I know everything is fine in the combustion
chamber. I won't be sleeping much tonight either because I can't wait to
jump on again and go for a blast and it's only 30 deg. here. I don't really
care if it is -30 deg I'm riding this baby.

YEEEEEEEEEHHHHAAAWWWWWWWWWWWW!!!!!

I just took the bike out for it's first run around the block. It runs great! I have to wait for colder plugs or I would have never come home. It takes a bit getting use to working the fuel shut off but I am getting the hang of it. Other than a little bit of fuel spill now and then it is a great mod. The sound of the blower can be heard inside my fullface Shoie helmet and over the boom of the Dunstall silencers. I still have to do some polishing and replace one of my oiginal leaking petcocks but this thing is awesome. I have always wanted an 850 Commando and I never would have even imagined I could have a supercharged one. I will send photos when it is completed to my satisfaction but let me tell you this.

I ride a nitrous injected Honda 996 Superhawk as a daily ride and I have a few GP race bikes but nothing, I repeat NOTHING!! stirs my soul like this setup. The only other mod will be a steering damper because the bike lifts up in every gear now and it upsets the steering and a gunfighter seat from Corbin to keep me from sliding off the back of the bike when I twist the throttle. In closing all I can say is YEEEEEHAWWWWWWWW]

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
