ok, my old road racing pilot and i built a period correct 1921 privateer board tracker. its an awsome machine [the one in my profile picture] now just to get the base of our questions set. its got no suspention, no nuetrual [direct drive] and no brakes. we have no problem putting a single rear brake on it and of corse good tires, but do not want to molest this historicly correct machine.
can it be direct drive [we would have to push start it] its ok if there is no class for it we just want to know what it will do
i will figure post pictures when i get them...also we have been asked to have it shot for american iron magazine, im sure we can do both this september in willmington

Looks great some more pictures would br great.
Could you borrow some starting rollers from someone?
Start it on the rollers, clutch it and push of the rollers then ride away from there?
Cheers

Before I would do any modifications at all, I would contact the motorcycle tech folks at ECTA and ask for a rule variance to run it the way it is. How fast do you think it will go anyway?
-
The push start bit is something I can't address. It has no clutch correct?
But you will need a couple things like a chain guard a teathered kill switch and a fuel shutoff the rider can operate from the seated position. And the rear brakes. If all of that is OK and the proper safety wire and all then it should go through tech . I assume no battery. I would love to see it.
-
I've seen roller starters for bikes numerous times - but don't know for sure at all about a push start for them. Streamliners -- yup, no problem with a push start. But P/P, M/anything or A/Anything - - I've got no help. Look it up or ask the officials for an official answer. Van Butler or Matt Shuss are the two guys you'll want to find. They're in the '12 rulebook.
-
I think as a board tracker it has no way of disengaging the engine from the wheel. A person would push it in gear with the ignition off. Then the rider switches on the ignition and away you go. I believe they tow started the bikes on the board track. After the race you just shut it off and coasted to a stop. If you put it on a roll starter and got it running I would think it would wheelie stall or snap the chain when it moved off the roller. Ask Todd and Joe
-
I'll reinforce that you'll have to ask the motorcycle tech committee - pretty sure there is contact info in the rule book.

It sure would be neat to see this piece of history run down the track. Obviously all safety requirements must be met, but outside of that, perhaps a time-only run would be allowed. Please let us know what you find out!

Slim,
ECTA question - not connected to the SCTA rulebook.

ransom t, how fast.....as fast as it will go! it would be nice to see 100mph. however fast it goes i hope its not faster then my buell...LOL!
i know the deal, i got a few calls to make. will post a few pictures as soon as i get them. i would for sure want a brake on it. yes its direct drive, no gears, or clutch.
dam thing is loud with 12 inch long open pipes.

What is the displacement?

Runt13,
Do you have a 2012 ECTA rulebook? If not, you can order one, go to ecta-lsr.com. Please review the motorcycle rules. If you have any questions, please give ME a call.
Thanks,
Joe

Runt13,
I see from another post that you have a rulebook. You will have to follow all of the safety rules outlined. You can have a crew member push you off if you want. I for one would love to see the bike sitting in the pits even if you decide to not modify it.
-
I will be there in September and would be glad to push a 1921 motorcycle off to race again.

my 24 volt , plug in , drag style starter broke at the bub meet a few years back.
the jessup family from texas were ready to tear down for their record.
they loaned me their roller starter for the rest of the week.
there is a learning curve with those rollers .

I use a Doc Z roller starter every meet for the past few years and I agree with saltwheels262 that there is a learning curve with the rollers. However for this bike with direct drive and no clutch he cannot use rollers as when he moved off the roller onto its ramp it would launch the roller system backwards and the bike forwards at an unpredictable angle. That would be dangerous for all those around him.
-
Good to know that Joe is the go-to guy on scoots. Being not a bike guy it's one of many things I didn't know.
I don't see how to use a roller thingy with no clutch. But those board track guys were crazy, THAT I know!
Dan

well guys the first thing is brakes, there is a period correct rear brake / clutch thing but its pricey like 1500 bucks. then we would have to lace it to the wheel. find tires that are worthy and such. i will post pictures tonite and give joe a call after work.
we also got a 98% correct flathead, and another flathead that is close. maybe i can get the guys to bring them to ohio for display.
i can see this LSR stuff can be very addictive, time consuming and a heck of allot of fun. i got a AHDRA drag race in 2 weeks, then its LSR / LSR / LSR / LSR. everything i look at is now....what will that do at willmington. [remember i work on a golf coarse, were everything is slow]
RUNT
IT WAS 61CID STOCK, NOW 74CID WITH PERIOD CORRECT MODS.
i really don't think it will go 100mph.
-
I try to put all my money and time into land speed racing. Otherwise it goes to waste.
How fast do you think you can get a golf cart to go? I mean if you strip it down put in a cage and add some more batteries. :-)

Could you start it and leave it idle on a stand, and then "drop it" to run?
-
after a few to many beers the slowest golf cart is way to fast.
RUNT
-
Remember the E. J. Potter method: jackstands while the engine runs in gear, drop the stand to launch.
A stand could be used (the usual type has slots or hooks for the swing-arm ends, axle, blah, small wheels, and handles at 90°), handles up (relaxed) while on rollers. As the engine coughs, the handles go down and the tire clears the rollers. Idle for a minute to heat the engine up, push the bike (still on the stand) away from the rollers and let-r-go.
-
Why not just push start it like they did when the bike was new?
Gary
-
Dropping a spinning wheel on a 90 year old motorcycle could brake the chain or a spoke. Pushing it would be safer.
-
ok, we got the STARTING thing figured out....we push start it after its warmed up on the stand. lol.
now if anyone has a extra 1500 bucks for the period correct rear brake / clutch thingy that would be a real help.
got a bunch of pictures today will post tonite....promise!

I'm with Gary. During the era of the board tracks it was pushed off, raced, shut off and putt putt to a stop. Now that was when the men were made of iron and the track was made of wood. What about an exhibition run or runs? I think the powers that be (ie. the race director) may go for it. I hear that he IS the owner of the worlds largest honda 4 collection. I'm not a bike guy (i fall off of them, even when going slow). But I would love to see the history!!
How about it race director? Do some of that director stuff!

I think replys 11 & 12 from Joe Timney answers any questions. The rules are for everyone. The insurance companies read the rule books. If something goes wrong they will be all over it. The bike is beautiful and is a show piece, display it. :cheers:
-
It has pedals. Are they for starting it? Cant you just pedal it going then hit the ignition switch? It also looks like a hand pump for the oil pressure. That is so cool. You will have to make some sort of chain guard to cover the top of the chain. Will the throttle snap closed when you let go of the grip? Will it return to idle?
-
Do the pedals drive through some sort of sprag clutch? Or must the rider keep his feet up to speed when under power- or keep all his limbs clear of the pedals? :-D
-
Nice toy Runt! :cheers: :cheers: :cheers:

I'd guess it'd run afoul of the notion that you can't disengage the drive line. That's what happened to the three-wheeled blown DeSoto fuel dragster with casters that is an all-time favorite of mine.
-
pedals are fixed, this being a period corect board tracker, thats what they did, has a kill switch, throttle returns, chain guard is being fabricated and the best news......don went to the southern old bike meet and found a brake, at least most of one....we are on our way.

brake is on! only $1000.00 at the end . now the chain guard

Would love to see photos!
