With a hand written time slip I must be back in the 70's again. Tell them to get with the program and invest in new timing equipment, you know the one with out tubes.

Yea, your close. These are not recent time tickets. I have not ran that bike in 15 years or so after the transmission went out. I'm not even sure if that track is still in operation. I was thinking to take it down to one of the small tracks around here just to play for a day. So, yea, to beat my times your up against some very old technology. I never tried a lowering strap.

The new AMA rules may be down loaded here if you have not read them:

http://www.amaprostar.com/noframe_rulebook.asp

Read section 2.3.2. "Artificial or temporary tie downs (, i.e. tie down straps, cables, limiter straps) are prohibited on front forks."

If your racing at a small mom and pop track with nixie tubes in the counter, there techs. may not check your strap and let you run with it. Seems like you would want to use a block instead, or just put a tire and set of bars on it.

If they do let you run with it, post your new times.

Our track won't mine. If the front straps work and there is'nt to much bounce at the front end during the end of a run, I'll pull the front springs out and slam it to the ground with another 2 more inches. Also install some rear struts today, 10 inches from eye to eye. Can't even used the kickstand now, half to use a brick under the frame. I'll let you know how it turns out.

That's the nice thing about those small mom and pop strips. They let you try things out if you play it safe.

I did manage to turn this one up:



A bit hard to read, but it's from 1987, 60' 1.867 versus your 1.88. Of course my trap speed is only 62MPH. 8O I think the tree was .5 seconds offset at this time, that or I had a few drinks the day before. :roll:

I think that dropping the bike down is going to help you to a point. But you may not be able to detect it depending how consistant you and the bike are. There is a a minimum 2" ground clearance requirement, with the riders weight on the bike. Do you care if the bike remains street legal? The stock 83 swing arm had just enough room to mount a small tire in it. Do you know if it is the same swing arm and brake as your 82 E?

[RacingJake]

I think the swingarms are the same. My old tire is 5 inches wide and I should be able to go with a 6 inch wide tire before having to use off set sprockets. My real problem maybe the rim, 17x 2.50.

I had a custom 18" rim and spokes made up to fit a Honda (no longer remember the bike) hub. I used a 7" skinny tire on it (PN 808-891-919). Tires may be found here: http://www.racegoodyear.com/products/racect14.html

The setup looks like this:



You can use the stock chain and brakes. Just pull the street tire and bolt it on. I did this back in 85 or so for around $400, including the tire. The tire was VERY tight and I had to make the brake arm braket to get a little more clearance. Check into the swingarm on yours and see if it's the same part number. Or the next time you have it apart, take some measurements. If it looks like it will fit, maybe we can work a deal, or I can look to see if I still have all of the information.

Jake,

I looked around and found the information, just in case you want to just make your own.

I had the work done in 1986.

I had the rim made by Buchana's Frame Shop (818-280-4003).
Rim PN# RDWM61840 3.50 X 18" DID Rim U/D 40
Drilling, nipples and spokes $197.00
The hub was from a 1976 Honda CB 750F (I think)

[RacingJake]

Thanks, how's about $10. I do have a gs750 parts bike with a 18 inch spoke wheel that I could use with a wider rim. I'll keep that in mind if I ever go to a wider tire.
