Okay guys, I got one crazy-A$$ idea to bounce off'ya. Just so y'all know, I have the equipment, materials, and skills... I CAN build this... but if I do, I want it to be functional, and downright cool, so I'm looking for suggestions. I'm considering building a motorcycle based on an Allis B engine. I'd build it stressed-member... meaning the engine IS the frame... the front half (steering tube, triple-tree/forks etc) would bolt to the front of the engine... while the rear half would bolt to the rear. Yeah, I'd hafta use an Allis fuel tank... and a pair of tractor headlight buckets... and a steel pan seat. I considered using an ag-tread rear, and a tri-rib front, but... they're not DOT approved... and I'd certainly get it titled and registered as a motorcycle... and I'd wanna be able to put it on the interstate at 70mph. I'd obviously nix the governor, and hafta make it spin freely from idle, to some speed HIGHER than a normal goverend tractor... mebbie 4500rpm or so. Lighter flywheel for CERTAIN... Beyond that... transmission, clutch, rear suspension, drive... all up-in-the-air. I'm thinking shaft-driven with a single-sided swingarm made from a substantially-reengineered front axle from a Jeep... or something like that. Whadd'ya think? ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

| Too much down time? Just kidding. It would be interesting. Not much help on design ideas though. Best wishes on your idea. |

| I usta think a JD A engine in a VW Beetle would be the thing to have. You could reach out through the windshield and push the clutch in. |

I was with ye making a new super duper collider snow machine with settings set for Blair Nebraska...and snow that dude that has thet snow maker under about 30 feet os snows.... ... but ye lost me at the word 'motor snickel'...  If that engine can hold the tractor up, even after it comes dropping down, it should be tuff enough to be used that way too for holding the front assembly of a motorcycle on the road at 70 mph.

I think you been getting into the new years bottle too early Dave.... LOL All laughing aside, that's how BIG things got started. I can picture it in my mind, so it would be FUN! HAS to be water cooled, tranny would be a real problem as you wouldn't have to shift... suspension?? GOTTA have the shocks that hold up the seat of the WD/WD45. I still think you've been into the new years stuff too deep... ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

Okay, well, that green tricycle has a built=in headrest...  Like I said... highway-driveable... suitable for a license plate. Yeah, I think the B engine is structurally suitable as a stressed-member. I also think that it'd be okay spinning a bit faster than it's governed speed without too much worry. Getting several speeds out of it, and driving the rear wheel... will require some engineering prowess, but fortunately, the B engine is narrow, so it won't be difficult to straddle. I'm thinking that if I can make a transmission bellhousing with integrated swingarm pivot, tuck some spring-overs underneath, the rest is just figurin' how to get a transmission in there, and drive to the rear wheel. Magneto, carbeurator, and hand-start... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

| No question an automatic would be handier than a suicide clutch/manual although not as "cool". Hey! How about some kind of hydro drive and driven setup? Can that be over driven?. Chug along while orbit is buzzing! |

Oh, Man- I forgot all about the TurboEncabulator... Dang... okay, lemmie see... I think I got one, mebbie two'a those in the pole barn... underneath the shelf with the Sachs air-cooled Wankel rotary... The 'early' Boss Hoss uses a 90 degree gearbox coming off a conventional clutch housing, and a vacuum booster. I say 'early', because the one I rode (my neighbor built one) had it... I dunno if they've changed it since then, but the gearbox was really similar to one you'd see on say... a bushhog mower... but the gears were cut for much higher speed operation. A mower gearbox can take a beating, but their upper speed limit is about 1200rpm. Hydrostatic... hmmm... hmmm... hmmm... BTW... Bud Haggart was a talented guy. I could NEVER make it through that video without breaking out laughing, much less choking up on the technobabble... but he could do it with a totally straight face without losing a beat. I'm thinkin' the cameraman had earplugs on, and his head in a paper bag, to keep from throwing Bud off...

There are a couple of "bikes" around here similar to what you want to build. One is powered by a flathead Ford V8, the other with a smallblock chevy. Both have no transmission, just a clutch and some type of angle drive. Engines have plenty of torque so a transmission is not required. |

| Might have to take the motor to a specialist shop and have it balanced through and through. Other than that. -- its a go for it. |

Well, after thinking about it, Mike, and Tom... if I were to go hydrostatic, I could certainly limit it to under oh... 2500, and run my hydraulic ratios with final drive to yield sufficient road-speed without having to spin it that fast. Let's say I use a shafty swingarm, and couple a hydraulic motor to it... a 29" OD tire being somewhere in the vicinity of what... 750 rotations per mile, that'd make 60mph occur at 750 TIRE rpm. If it's a 4cyl Goldwing rearend, it'll be somewhere 'tween 3.09 and 3.44:1, so that'd be around 2500rpm of the driveshaft. If I use a hydraulic motor suitable for 4000rpm, and a hydrostatic pump that, at full-swash, yields a .50 ratio (meaning, two motor rotations for 1 pump rotation), then the B's 1800rpm would swing 3600 at the driveshaft, which comes to 1091RPM, which with that 750 rot-mile tire, yields 1.45 miles per minute... that's 87.28mph. I'm thinkn' that'd be more than fast enough for my intentions. At 65mph, that engine speed would be 1800/60*87.28 = 1237rpm. Yeah, that'd be a comfortable engine speed... Hydrostatic drives are thermodynamically inefficient... in the case of lightly loaded, they're a LITTLE better, because there's less waste heat generated. Cooling the engine and the hydraulic system will be an interesting exercise... and I'd need an oil reservoir for the hydraulics. I could use the frame as a reservoir, but that means the frame would get pretty warm. I could use the engine's oil pan... mebbie fab a new one that's bigger, and use engine oil as my hydraulic fluid, then have an oil-cooler for the hydraulic return... it'd serve double-duty... or mebbie I could nix the aqueous coolant, and do like the Suzuki GSXR-750, just fill the cooling jacket with engine oil... Hmmm... that'd be far out, man... nothing but oil coolers... hmmm... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem.

Hee hee... 'blueprints'... Some guys spend a huge amount of time drawing things out, which I understand... some guys spend huge amounts of time building every last piece, before ever making one component... Unfortunately, Ted, the economy of engineering is biased heavily upon available time use. Most things I build, get built inside my head extensively... they're 'greyprints'... and it's not unusual for me to pattern parts from cardboard, plywood, and thin sheet, then go straight to the finished part, in a very short number of steps. I tend to limit my design time to forward-motion aspects of a build, the rest happened in the past... I just take it from the original concept format, to metal. I expect to change design aspects , but not 'till after I've done some testing on mock-ups, and oftentimes, those mock-ups are metallic, so I just dig in and go. I wouldn't leave 'ya without pictures, though. And I just remembered- I got a stuck B engine down in the barn... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem.
