Speakin of Bonneville and all, I just seen "Worlds Fastest Indian" and I kinda got all misty and such, the wife was pointin at me laffing(like I do to her when she gets that way watchin chickflicks). I loved that movie.... | ||

Jack, I was being a little facetious. Of course I know how to work out the gearing. Presently it's geared to pull 25mph per 1000rpm 5000rpm = 125mph. It's geared to be rideable from a standing start. Changing to different sprockets for a taller ratio is easy and entirely doable, but getting it to move under its own steam might not be possible. A push vehicle at Bonneville for example, could see gearing go way up and beyond 200mph, and with a powerful motor in it I've no doubt a good number is achievable. Be that 150mph or even more. Thanks for the offer though, and my apologies for pulling your leg. Rocket | ||

Thanks for the info, that's pretty much what I was wondering. Jack | ||

If its geared to run 25mph per 1000 rpm with a single speed transmission then a wild ass guess would be 1.25 to 1 output,you didn't state the final ratio but another wild ass guess of 3.00 to 3.20 so I'd say MAJOR clutch slipping to get under way or use a tow vehicle to get you up to speed and then dropping the clutch. | ||

Rocket has his axe to grind, I have mine. Looks like HD will be doing the XR1200 ! (90328-08, 88227-08, 50695-08, 940490-08, 57262-08,57260-08,53920-08,90363-08,53976-08,) "Be the first on the block with accessories for the Softail Cross Bones and Sportster XR1200 Models." Hard to imagine that they are doing accessories for a bike that they arent building, arent releasing... Where is my piggy bank, time for a deposit. Now Buell just needs to pull the trigger on a 450 SM/DS to fill out the garage. | ||

Sounds like a transmission would be a nice thing to have but I think I see the problems with that. Mr. William Gelbke, one of America's premier motorcycle designers, used Chevrolet's venerable two speed Powerglide automatic on his first design: http://www.factoryfat.com/roadog.html But once they got production rolling they went with a four speed automatic: http://www.factoryfat.com/autofour.html Many believe to this day that the unfortunate choice of a BMC-Leyland engine for the Auto-Four is what sealed its death warrant on the American market. Those puny little British engines just didn't have much appeal to American buyers back in those days. The 110 foot turning radius and a couple of other kinks on the Auto-Four FIM Grand Prix prototype were still being worked out at the time of Mr. Gelbke's untimely death. Rest In Peace, Wild Bill. I guess things have come full circle now, what with your's using an V8 engine with American roots. Jack | ||

I guess things have come full circle now, what with your's using an V8 engine with American roots. Somehow I don't think so Jack. Gelbke seems to have suffered the same problem Buell have with their 1125. They both think looks don't count. And that's a huge advantage my V8 has over any other contraption like or similar to Gelbke's offerings. Mine was purposely built to look like a real motorcycle, and it does so admirably. Try find yourself anyone anywhere in the great US of Eh, that's built a motorcycle with a V8 engine equal to the length of a CBR600 sports bike. You won't. Make that can't. The sacrifice of going direct drive was a small yet intentional price to pay when it came to putting this V8 together. Because of such, it is instantly recognisable as a motorcycle, and not some two wheeled junkyard dog knocked together in Hicksville. Rocket | ||

If you were ever to make it to Bonneville with that Jeff Foxworthy "Hicksville" heap and by some odd chance they "let" you make a run you'll wish you had the "extra" wheelbase. E.J.Potter "The Michigan Mad Man" built and raced them(over thirty five years ago) and went well over 160 MPH in the quarter mile. But he mounted the engine in the frame properly without the use of rebar. | ||

You are a funny bunch when it comes to offering criticism. What's rather telling to me is the typical sore loser attitude displayed by several towards the V8 bike, just because I criticised the looks of the 1125. You're so very transparent! As for the wheelbase. Why would I wish it any longer for Bonneville? Rocket | ||
| Captpete |
Rocket, Wonder if you ever saw any of those conversions they did years ago using those little Ford V8 60 flatheads? (The only one I ever saw in the flesh was in the early 60's.) I don't know what the 60 stood for... maybe horsepower? The normal sized V8's were called 90's. | ||
| Jackbequick |
Pete, Ford V8-60 = 60 HP in its first implementation. That was a stunning amount of HP in its day. And that was the world's first mass production V8. Rocket, E.J. Potter had a different venue in mind (drag racing), and his effort looked like a motorcycle suitable for that:  His V8 drag bikes were prior to the CBR600's time but the length and proportioning of the bike seems appropriate and suitable enough to me. The "Roadog" was a cruiser, admittedly somewhat unusual in appearance, but it has a beauty of its own. I think the length was merely a result of accommodating the pieces he wanted to use (engine, transmission, etc.):  And did you not know that increasing wheelbase that can add stability at higher speeds? One of my unimplemented motorcycle designs is for a chopper based on a Bultaco Sherpa T. I figure that extending the forks 12" and going to a smaller rear tire (part of the intended low rider look) will cure that particular bike's well known problems with directional stability at higher speeds. Those things are just a high side looking for a place to happen. But you know how it goes when someone has a lot of blood, sweat, and tears invested in something, it is just hard for all of us to see things the same way. I think some additional length on the Streetfighter, if it could have accommodated a transmission, would have made it a more practical machine, no? How about this concept. A hydraulic pump on the end of the crankshaft and a hydraulic motor in place of the bevel gear drive at the rear wheel. Couple that with a rider controlled proportioning/bypass valve and you probably could have an infinitely variable transmission with little or no increase in length. But let me ask this, was it really necessary to denigrate Mr. Gelbke's efforts? He is a hero to some of us. Jack | ||

I think Jack's post was very noticeably, to me at least, full of underlying sarcasm. You really think I wouldn't spot the feeble attempt to wind me up? Try again. Comparing my V8 to something at least 15 feet long? Yeah right. What would lead anyone to believe my V8 needs more wheelbase for stability or LSR racing? All this shit is about is my unflattering comments toward the 1125. Give it your best shot. Jeez, it must really piss some of you off that my V8 is actually far better than Gelbke's crap, which other than sitting on two wheels, is not a motorcycle in any sense of the word. His V8 drag bikes were prior to the CBR600's time but the length and proportioning of the bike seems appropriate and suitable enough to me. BUT THEY'RE NOT LONGDITUDINAL MOUNTED ARE THEY. ANYONE CAN MAKE A V8 ACROSS THE FRAME WORK EASY USING A CONVENTIONAL MOTORCYCLE TRANSMISSION. TRY DOING IT WITH THE MOTOR LONGWAYS IN, AND GETTING THAT CBR600 WHEELBASE Next? Rocket | ||
| Captpete |
How about this concept. A hydraulic pump on the end of the crankshaft and a hydraulic motor in place of the bevel gear drive at the rear wheel. I think hydraulics are a pretty inefficient way to move power around. Lots of friction pumping that oil about. My hydraulic reduction gear in the boat generates so much heat that it needs a heat exchanger to cool the oil. I should have a heat exchanger for the deck machinery as well. That crap gets hot, and most of it is intermittent duty. I think Jack's post was very noticeably, to me at least, full of underlying sarcasm. I don't see any. Capt Pete | ||

Rocket, you remind me of the heavy coke users peering into the bushes around the house at night, looking for the IBI they are certain are out there. (Invisible Bureau of Investigation) Sorry, mate, but I still don't see it. Not that there hasn't been a bunch thrown your way by other folks at other times, but not this time. Capt Pete | ||
| Rocketman |
Well Pete, let's just say Jack knows I'm right, and if he were man enough he'd admit I sussed him. But really, I couldn't give a monkeys flying left testicle. That, and I enjoy blathering him wrong. What does concern me is how you seem to be keen on telling me when you think I'm right or wrong. In this instance, you don't know the history behind the blokes comments, where as I do, and I'm not blind and I'm certainly not stupid. Nor am I paranoid. But thanks for feathering the blokes cap. I'm sure he'll pat himself on the back for a job well done. Did I mention my V8's longitudinal and Yorkshire born 'n' bred, so there Jack  na na nana na  Rocket | ||

What does concern me is how you seem to be keen on telling me when you think I'm right or wrong. Yeah, you're probably right about that. Better off minding my own business. Lord knows, I've got enough of that to keep me plenty busy.  Capt. Pete | ||

An opinion's a bad thing to have around here these days. I see Ducati laid down their long term future plan, which states by 2009 they'll be firmly committed to building motorcycles for the premium sector of the market. What a bold move. Giving their true fans what they've wanted all along, without watering down the Ducati brand with 'budget' Ducati's. Rumours abound of 800cc Moto GP replicas at a more affordable price than the current 990 offering. Wow factor wow factor wow factor. Of more interest to the Buell and the Gang though. Ducati are already close to finishing a 1098 super naked. Of course, being Ducati, we can expect it will be a class leader with the 1098 motor, but more importantly, its looks will no doubt be stunning. Ducati know more than anyone else, looks count. Unlike some manufacturers I can think of, Ducati couldn't sell an ugly motorcycle if they wanted to. Rocket | ||

The Multistrada isn't ugly?  That's news to me! | ||
| Rocketman |
The Multistrada is a stunning looking motorcycle which very cleverly draws on several different aspects of the two wheeled market, and joins them together in harmony as one bike that suits multiple rolls very nicely. With the looks of the Multistrada, some people can't get their head around it. But I'd be interested to argue which bits anyone finds unattractive or out of proportion or even at odds with one part of the bike to another. You know, like how an 1125 is. Rocket | ||

But I'd be interested to argue which bits anyone finds unattractive or out of proportion or even at odds with one part of the bike to another It's ok with me if you like it Rocket, but I don't have the desire to go who knows how many posts with you on it's merits or lack thereof. So instead I'll suggest that the world motorcycle press overwhelmingly agrees with me. | ||
