Not Bonneville, but El Mirage dry lake bed. I recently purchased my old big block roadracer that I had sold 23 years ago. My plan it to prepare it for a land speed record attempt at El MIrage in May. I am well on the way to getting the bike ready to pass the SCTA tech inspection. I do not expect to top the effort of a few years ago by Team Crowbar (I believe). I really just want to see what my old race bike could do, and I'm not interested in "professional money burning", at least not past a certain point...
What I could use...
1) I need a 10 spline to 20 spline driveshaft adapter so that I can try some Convert rear gears on my 5 speed bike.
2) A place near El Mirage where I could store a trailer and motorcycle and tools and gear for the racing season (May to November).
3) Perhaps some logistical help, places to crash, pit crew help, etc.
Feel free to respond here or via PM if personal info is involved...
Mike

The shaft you need can be made using the front yoke of a 10-spline mated via u-joint to a Convert drive shaft.

Hey, another LSR guy :thumb: I run land speed racing on the east coast and my 650 Triumphs hold a few records....My race bike rider ran a stripped down cafe style high mileage 84 Guzzi 950 at the Ohio mile ,117 MPH........
El Mirage does not have the MPG class shown in your photo. You will have to run altered class....The record in the 1000 cc pushrod gas class is 153 MPH.....
From my experience and watching other bikes there's a few inexpensive things you can do to increase speed....Lower the bike as much as possible, you should be able to slide the fork tubes up in the yokes......To lower the back you can make some solid struts to replace the shocks...many bikes run solid rear suspension...
If it's a naked frame bike the rider's position is all important...Viewed from the side, when in full tuck, the riders back need to be level..Having your ass lower than the helmet costs speed...You may not get the position with the fuel tank on the bike..
Safety rules are simple, safety wire the axles, tether kill switch, and the tire speed rating must match the class speed record in SCTA rules...That would be VR or W rated tires less than 10 years old for the 153 MPH record...
Good luck and be prepared, it can be addictive.......... ...
-
Thanks, I was prepared to run A-PG, but SCTA decided to add M class for motorcycles this year. Since my V rated tires are only good for 149, and Z rated radials aren't allowed with tubes, I'm going to get the tires shaved to raise the speed rating. I may remove the extra padding I added to the bum stop for road racing to give me more body position options. Short shocks are on order, and I have already moved the tubes up the clamps the max. If I don't hit 130, I'll be extremely disappointed.

Sounds like you have a good start...... My old Triumph MPG650 runs 126-128 mph back east on paved LSR tracks with 55 rear wheel HP...The air density at El Mirage cam be lower but I think you can run 130 or more ...Good luck !

Rough edge, I have a stock 51 triumph except gas tank and fender. What would I have to do to run at Bonneville?
Does the salt immediately ruin the bike?
Wanting to run down there a non competition bucketlist thing

You might try to hook up with Dead Lake Racing. Great bunch of guys racing on the cheap selling T-shirts out of their trailer. They're road racers but racing is racing and I'd bet they would be happy lend a hand.

The salt is a nuisance and may promote rust but it can be washed off.......You bike would fall into vintage modified production...You have to safety wire axle shaft and nuts, have tires that are less than 10 year old with a speed rating to equal the speed record of the class you run in...And you may have to install fire resistant covering on the fuel lines. The bike needs a tether kill switch you hook to your sleeve to kill the engine if you/re thrown off the machine, or bail out.. And the bike overall needs to look decent. You need to wear full leathers with sewed on metal zippers , a 2005 or maybe newer helmet with a Snell rating, boots and gloves...Go to the SCTA website and buy a rule book....It's has all the requirements.. I believe to get on the salt may be about 600 buck or more...

Concerning storage, there is a gliderport there. Many pilots are bike enthusiasts. Maybe someone there would spare you some hanger room or assist in finding storage. Best time to catch people there are weekends.

Thanks...
Thank you! As I mentioned Saturday, I last saw the bike at Nelson Ledges in '92 (I think). It made a lasting impression, and is a big reason why I have a Guzzi today.

That's what I thought, wasn't sure. Thanks.

The fellow I sold those Astralites to is willing to let me borrow them. As it turns out, narrow tires are better for LSR attempts.

I do have a coupler. Send your address and I'll send it.

Made my second trip to El Mirage this past weekend. With a bit of luck (high tail winds, and bar set low to set record), I set a land speed record in the 1000cc M-PG class. My speed was 136.3.

Thanks Mike, that is impressive, I want to ask: how much is left to squeeze out?

Thanks Mike, that is impressive, I want to ask: how much is left to squeeze out?
Honestly, I had a 17 MPH tailwind that was about 45 degrees off axis. While I can always hone technique, I doubt there is much more to be had out what was a roadrace motor. My bike was dyno'd at 71 HP at 7400 RPM (incredible torque). I assume 9% loss for altitude, and your left with 64 horses. Given I'm in the no streamlining class, I doubt much over 135 with no wind would be possible. I was geared too tall, so with some slightly shorter gears, I could possibly go faster. I could also clean up the aerodynamics of my bike without violating class rules. This is a soft science, repeatability is the key. I now have two weekends with two different gearings. I've had 3 runs, 115, 129 and 136. I like that trend, and would love to go 140 with this bike as that is what it was clocked at, at Daytona by AMA radar. Right now I have a huge 100mm tach that I could pull, but then I'd lose information. I also have a sidestand on the bike which I could pull, but I like the convenience. Now that I have a title, I don't really need to chase that. Simply running is enough fun for me... That said, I would like to have a 85 HP motor... Mike Rich?

Mike Rich.. :smiley: Yep. The Mighty Scura rocks with Mike Rich flowed heads. I'd think it would be the best bang for your buck.

136.6mph is a hell of a record. :thumb: congratulation .
how long is the track ? ( just curious )

I seem to remember posting a while when you had a photo with the Eldo with a HUMUNGOUS ceeegar that you looked cool, see time hasn't done you any harm then
Thanks for posting

1.3 miles to timing lights. 1 mile post finish to slow down

what RPM at 136 , Mike?

Congratulations!! Well-deserved... :boozing:
Would love to see what she'd do with a proper streamlined skirt on... :evil:

Congratulations Mike. That was quite a jump in performance in two outings. Way to go and that motor sounds great.

With no wind ,about 130 MPH sounds correct for 60 ish HP on a wide frontal area bike like a Guzzi... My Triumph in 650 MPG class runs 130 mph in the 1-1/2 mile with about 55 rear wheel HP.. That's in Maine at about 800 ft elevation and high humidity...
I found the fastest speeds came from gearing the bike for about 500 rpm less than peak power at the "target" speed..
Riding position is very important on a naked bike...The rider's back needs to be horizontal and ideal is the helmet slight lower than the ass.....You got to get rid the beautiful fuel tank and install something that allows a lower riding position.
But... you set a record and that's all that matters !!!

Had my 3rd weekend of racing at El Mirage this past weekend. Up until this point, I had made a total of 3 runs, 2 my first weekend, and 1 last month at my 2nd event. For this event I managed to squeeze in 3 runs, doubling my total, all before 1pm. It was brutally hot, 105 degrees, with no to little wind. Here is my race report...
First off as you may remember, last month I set the record for the M-PG 1000 class on my 1975 850-T (992 cc) at 136.3 MPH, while only pulling 7000 RPM. I knew I was geared too tall, but I needed a data point being too tall, all my previous runs I had been too short. That run I made with a standard wide ratio helical cut gear 5 speed from most any 70's or 80's Guzzi mated to a 8:33 rear drive and with a 100/90x18 rear tire. In impound (still talking last month), while pulling the head for inspection of my CC's, I noticed the plugs looked lean. Fast forward to this month. I decided to shorten up my gearing. Not having any 5 speed options between the 8:33/100 and my 7:33/120, I decided to use a 9:34 convert gear set, but only use it as a 4 speed. This had the added benefit of reducing the number of shifts I had to make, a boon given my dodgy ankle. I also went up in the jets one step (152 to 155). Oddly enough, this is exactly what I used to run with this motor 25 years ago. I had leaned it one step for elevation before the season started. So to the racing...
First run, everything seemed great, I got her up into 4th gear, and she would only pull 7000 RPM. WTF! I was so rattled, I shifted into 5th which was a big mistake, and she immediately bogged to 6200 RPM, and I ran 131.9, 4.4 MPH less than my record. Convinced my gearing was right, plus, not wanting to have to switch rear drive units in 105 degree heat, I put my jets back to where they had been. 2nd run, felt good, pulled to 7750 RPM in 4th and I held it. Speed, 141.693, almost 10 MPH faster than the morning, and 5.4 faster than the record. A side benefit of using the 4 speed option, I get into top gear earlier, and I have more time to work on my "trim". Tucking in, getting elbows and feet and legs and helmet, just so. Had to go to record certification impound, only this time since I had them seal my motor last month, I did not have to pull the cylinder head. Got out of impound, and got in line for a third run. Managed 140.93 at 7700 RPM. Nice to see a backup within 1 MPH.
So my goals for this project, turn my old racer into a LSR bike, go as fast as it had ever gone (it was timed at 140 at AMA Pro-Twins qualifying at Daytona in 1992), set a record in my class, and then beat that own record... have all been done. I don't think there is much more left is this hoary, tired old road racer, but I'm going to continue to try and go faster through some gearing and subtle aero mods, etc.

Guess with all that heat the air molicules are farther apart so less air resistance. :thumb:

Before anyone gets crazy heaping praise, remember Bill Ross and his Team Crowbar bikes went much faster. In my class at Bonneville, I believe he went about 158. That is impressive!!

Bill and I were talking at Commie Nick's wake, :sad: and he said, "I'm having a medical issue. If that doesn't work out will you ride the bike? You're the proper size."
"Oh, hell yes." :smiley:

Heck, Chuck, just take the mighty Scura.

Shoulda went faster with that 200mph tape on the seat !! Congrats

LSR bike for sale on ebay

Why have you decided to sell?
-
testing waters... don't actually expect it to sell. cant do other things unless I recycle cash... It gives me options.
its either sell, or pour $ in. or as yogi berra once said, "if you find yourself at a fork in the road, take it".
Why have you decided to sell?
-
It might sell, it's not a "pile" so it just takes the right person at the right time. I'm trying to recycle some cash myself so that I can proceed. I want a better lathe and a milling machine to keep me amused during the long dark winter so I don't wander down the path too far.

Get that stuff, John. I'll be over to help entertain you. :drool:
