Open 100cc power

Might want to check out landracing.com, Jon has put a new section in about scooter LSR, and there was a group that rented Bonneville for running scooters, the person who runs the group is a member of that forum, just can't remember his name, and he also has a website.

Couple of suggestions I have, run a Kawasaki 100cc motor or bore out a CR85, keep it in one gear, do a little work on the porting, and go out and have some fun with it.

Might want to also consider running at Loring or Maxton, both are ECTA tracks, there is a LSR track in Texas, of course Bonneville, and there is a track in Australia if you feel like traveling.

The current ECTA record published in their 2010 rulebook for a 100cc motorcycle was set by Michael Schneider in June of 2008 at 105.011 mph. I have a little bit of LSR experience, still putting together a lakester to run on the east coast, if you would like to talk, just PM me or email me at slyonejr@yahoo.com, would be willing to help in any way I can.

Hi,

Where do you find the organizing bodies and their rules?

So far all I've found is something that says "no more karts" and a site that has 'speed limits' below what is being run at Daytona.

Thanks,
John

"Where do you find the organizing bodies and their rules? "

My friends (Wilshire Walkup, Lindsay & Charles Fox) went to the salt flats with their laydown Yamaha went by the rules on this site:

http://www.saltflats.com/

They had a good time although they said don't take anything out there that you don't want to corrode. I helped unload and clean their stuff when they got back and everything had salt on it. Tools, parts, pipes, everything.

Good Luck to anyone who makes an attempt.

According to the posters Jim Stroud and Drew Hockenson have hung in their shops.

Dave Bradley went 120 mph. That was an Alky 100cc Open (rotary valve, I believe)

They also, went through several motors......

Chris, all,
If your dad is looking for vintage 100cc, even 135cc euro motors, Theres an abundance of these overseas, japan, mostly in the philippines. Sirio, Parilla, PCR, Dap, Atomik, Comet, some piston port, mostly Rotary V. lots of these for cheap sitting in garages after everyone switched to Tags. Karting is big in asia since the 80's, they follow alot of european trends. You would think hondas are big in japan/ asia but not at all, in fact, most have never heard of shifters other than DD2's.
I think my dad has a bunch of Parilla & PCR 100's, let me know, they should be put to good use with what your doing. The dollar is strong in asia, you can buy anything for cheap

Hi Dave,

From that web site:

"Go Karts are no longer permitted at USFRA events"

There was no explanation given. Good thing they went when they did.

No idea what the other orgs say.

Thanks, it was a good thought.

John

Hi,

Just as an option I use to run superstock in sprint and road racing with a PCR TSL98 with an HPV clutch and a direct drive pipe. The only time i burned the clutch up was my first road race and before the green I had it sitting on the stall a bit to long Embarassed

. But beside that it always worked perfect.

Get an old rotary FSA motor (Titan, Rotax, Vortex) and run the 30mm slide pumper with gas, or dualies with alky. Alky will be quicker for sure, btu then you have to mess with your compression and ignition timing

Back in the 60s a Tony kart with a Parilla rotary valve managed 122 mph. It was a little "different" however.

So I finally got around to finishing it up. I decided to do it with some old school style while I was at it.
Ended up with a custom billet case and useing a italian scooter cylinder and crank. The thing is a monster, it's just plain scary to ride.
Gonna take the leg shields off and gear it up for some speed runs but it allready hit 68 on the gps fully dressed out and geared low... I think it will have no problem hitting 100mph.
Here's a link to the moped garage.

Thanks for all the advise and help.

That is a cool looking bike!
I would have though TM K11B 100cc WC rotary with a 30mm alky atomizer. Set the disc and ports to kill and hook it up with a CVT. Should be good for 45HP at peak.
Aero is essential as well of course.

Don't forget your steering damper!! My Honda Hobbit and Puch's are light in the front and without stiffening the chassis and swingarm bushings they're not easy to ride above about 55 MPH. The Puch is best and really improved with the replacement of the rubber swingarm bushing with brass.
Check with the guys at Treatland.tv and Mopedarmy.com for a combination of BS and some good help. Also, Nate at Motomaticmopeds.com can be very helpful.
