over the weekend i was at the meet and i was talking to tech and they said that the motor you use in a race bike has to come from a motorcycle, cant come from a generator or anything else like that, is this true?
-
Get a rule book... motorcycle engines come from motorcycles... if it came on a motorcycle produced anywhere at any time it would be a motorcycle engine. Be prepared to prove it if it is an oddball.
Submit your info to the motorcycle committee chair per the rule book.

There is an Omega engine class for motorcycles. This would include an electric powered 'cycle.
See Rule 7.J.13. :cheers:
-
A little more info Mikey, isnt it a special construction frame with 2 wheels and a Honda 4 stroke?
I'm no expert but 2 wheels, a engine, and a pair of handle bars would be condered a motorcycle :?
In my opinion your building a "A" body with a 250cc engine on gas. A/G 250cc, oh yeah and pedals :-D
I've seen crazy billet engines that didnt come from a motorcycle but a CnC machine and bottomless pockets.
-
Is there a 'mega' class for Boss Hoss bikes. There's hundreds of them 'manufacuted' out there. Anybody seen one on the salt?
-
I'm pretty sure that most venues~~ require motorcycle engines in motorcycles.
or a one-off engine that was built for that motorcycle.

"...or a one-off engine that was built for that motorcycle."
i.e. the V4 in the Bub #7 bike streamliner.
Search in the Forum archives and I'm sure you'll find a few discussions about the Boss Hog bikes and why they don't qualify as motorcycles for the sake of SCTA/USFRA.

"I've seen crazy billet engines that didnt come from a motorcycle but a CnC machine and bottomless pockets."
Hmmm....who owns BUB liner now...?...
-
Joe. I think I heard that Jamie Wagner had taken it on as a project. I'm not at all sure I heard it right, and if he does have it -- is it his alone or is he in a partnership with someone? Questions to be answered.
-
Not this Jamie Wagner. We still run motorcycles you sit "on" not "in". Maybe Jamie Warner??
JW
-
I think possibly Jaimie Williams...my point was more to the
"Bottomless pockets"....
-
Did the Bub liner run SCTA meets?
(Asks a roadster guy without a clue.)
-
No it did not. Not legal for SCTA rules.
-
Stan, it had cable steering and that was what kept it from running at SCTA/USFRA. I think that was it. Go ahead, someone -- correct me if I'm wrong. I know Denis once in a while is on this Forum -- maybe he'll see this and give me the answer. And Denis -- if you don't want to go public -- feel free to send me a PM and I'll spread the word without giving them your contact information.*

I dont mind going public with the stupidity that spewes from my mind :-D

I sort of remember a bike (175cc I think) that ran a record at Bonneville a few years back. I believe the engine came from a rototiller or something similar.
-
Did Weslake make Rototillers?
-
I know of a bike that ran an engine that was made for a Go Cart or something. But it was almost the same as the similar bike engine. just one plate was different. This engine was the kart version, but had an after market plate on it. So it was legal.
-
Yamaha made a 100cc go cart specific two stroke motor (kt100) that could have been swapped in. The one with the pull start snowmobile motor made look twice :-)
Once they got to be FI three cylinders with 200hp+ I expected to see some more adaptation but so far nothing new has come along.
-

Sure did!!

Triumph made twin cylinder aircraft power generators during world war two. They had alloy cylinders and were advanced engines for their time. They used them in a number of models they made just after the war. The engines have square finning made to fit behind a shroud and the bosses for the screws holding on the shrouds are cast into the fins. The "generator engine" Triumphs had a few important race wins in their day. They are prized now.

Those were 6Kw generators. The engines were based on the speed twin but used an alloy head an cylinder. Where they got the aluminum for that during war time is beyond me. The generators were for the RAF and went under the name of Airborne Auxilliary Power Plant. They were the basis for the post war GP Triumphs. Its amazing what's "prized" nowadays. Even LE Velos and M20 BSAs are considered collectables.

it is a pushrod motor so i believe i will be running A/PG 250cc, but tech said the motor has to come originally out of a motorcycle

what is considered an omega? i plan on running a 212cc generator engine that has been fully rebuilt
-

yes i believe i know what you are talking about, there is a motorized bicycle that runs at speedweek. They use a similar engine to mine except its a 160cc instead of 212cc. tech at el mirage said that it would be able to run at bonneville but not at el mirage. apparently the scta has different rules for different places...

yes my engine is used in a go karting a lot

Omega is defined in the rule book as Steam, Turbine or Electric

doesnt look like ill be running omega then hagahahaha

Oh......a generator engine not a generator as an engine. :-o

For many years we ran a 125c.c. Rotax Kart engine in a special race frame with SCTA/BNI and was declared legal.......due to the fact that the same engine was used in FIM motorcycle road racing.....I had documentation showing it was a "motorcycle" engine.....Tom Evans said "you are legal".............Thanks Tom.......love the man
I also build a 500c.c. bike using the power unit out of a Can-Am. (Rotax) snow mobile....it was the prototype for the 500c.c. Can-Am street bike...............This made it a "motorcycle" engine...........I had documentation....Thanks Tom..........................
