The Hospital (Kuwae) grounds had a world class track on it during my time on Okinawa. The Pro big name teams from Japan would come over quite often and those GI's who didn't mind getting embarrassed were allowed on the course while they practiced. I like to blame the riders weight as to why they were able make us look silly.

Back in 1976 the 185cc was a class, I had a TS 185 and a TS 250 set up pretty good.

Rode a little when I was younger, back in the YZ125 days. Now looking to get back into it mainly so I have a bike to put a track kit on for winter. Snowmobiling has always been my true love.

I can relate to this, when I go to the track they make me wear a jersey with a large red triangle on the back instead of a number to indicate to all the other racers that they are approaching a "SLOW MOVING VEHICLE", and that's just WORNG...

Awesome thread. First bike was a YSR 50, got it when I was 11, then my little brother wrecked it. After my dad calmed down, the frenzy started
Had: Z50, RM/YZ 80, CR 60, CR 125, ATC 250R, TRX 250R, RZ 350, and a couple more, and road all my friends bikes, as I started building them. Then the Banshee train came, last one did 105 on pump gas. Then I did a cartwheel at 70mph, after riding a wheelie to 4th gear-multiple fractures.

After recovering, got a CBR 600. Had it for a few months, and then sold after witnessing the worst wreck possible at a "street race".

Now I got nothing, and having serious withdrawl. Just looking for some oldies to buy and restore. If I would have kept half of my old bikes, they would have been a gold mine today.

There's a few gaybook groups that I've found that are good for buying and selling (or keeping abreast of current prices):

Mark's Vintage Motocross Swapmeet (might take him awhile to approve you to join, closed group, but he gets around to it)

If you aren't on gaybook he's at Vintage MX

Another one on gaybook is Vintage Enduro Buyers, and Sellers Guide. Mix of people posting what has been sold (for pricing) and some stuff for sale.

Neither page will have anything newer than 1989.

Bikefinds dot com is another good one - you can sort by type of motorcycle, year, state, etc, - it aggregates CL and ebay ads into one site.

Thanks KidA, I'm going to check this out. If I could find anything (2/3/4 wheels) unmolested (pre 89), that would be cool. I have a good wish list

Btw, I could not find the thread, but what are the specs (parts/speed) on that "rocket bike" you built and ride? I remember something about a cylinder/piston form another motor?

That's old school iron right there. I had a RM 370 I rode/raced at once time. Great bike for that time. I traded off an original Honda Elsinore 250 I had been racing to get it and race the open class.

I had the 250 and my dad had the 125. Great bikes.

That was my old 1979 P200 Vespa that I did a ton of motor work on. Originally a 199cc sitting on a cast iron cylinder putting out about 12 HP.

I tore the cases apart, trashed the old iron cylinder and added a larger piston and made a custom head for it as well as bought a longer full circle race crank which all-in-all increased the size to about 225cc. On the cases I ported them for a larger intake and reed-induction system using carbon fiber reeds. Added a 35mm Mikuni flat slide carb, billet aluminum clutch basket with hydraulic actuator, hardened gear set (the Vespa motor doesn't use a chain but instead a direct drive transmisssion). Had a custom expansion chamber made for the exhaust.

Put the hp at the rear wheel from 12 hp to about 30 hp. Increased top speed from about 65 mph to 90+ hp (my problem was with that larger carb I couldn't find an oblong wheel to add to the throttle to allow for the carb to fully open so I was only getting about 7 or 8/10ths throttle when fully open.

Dropped the stock weight from 238lbs to about 190lbs, added a front disk brake set up, etc, etc etc. 225 2-stroke putting out 30+ hp at the rear wheel on a sub-200lb bike let's just say it was quick, much to the chagrin of almost any car short distance and quite a lot of motorcycles too. It was way faster than my 1983 Husqvarna 250 WR and would blow my 1974 Yamaha RD 350 out of the water and that was a twin-cylinder 2-stroke known at the time as the Widow Maker due to the killer powerband. Top speed was limited to sub 100 mph due to the fact you can only fit four gears in the cases and without a chain and front sprocket you're limited in gearing. I could pull wheelies in first through third gear at speed without clutch action, both when entering the gear and when hitting the powerband.


And then I got clipped on the bars by some jackass passing me on the right and wrecked it and fractured my hip. Ended up parting it out and selling it. Last I heard the motor is in a scooter in CA being raced pretty regularly (though with all that power a clutch basket only lasts a few hours).

Damn, so the legend is true, I thought everyone was joking about "The Vespa". That's one heck of a build, and I would say that's more than major work--especially when the carb is almost half the size of the motor It's one of those Frankenstein projects, pretty cool and great work man--that kind of project determination is rare these days.

I know there has been a big movement in the last few years of people building "single cylinder/sub 75cc bikes", having top speeds around the 80 mph mark. It's crazy, the game has changed since I built them.

In the end, there's no better sound and smell like a few cylinders burning Castor

Man, you all are lucky. I tell you, the good ole days of owning any awesome (car or bike with a purpose) production machine is over. So much has changed--and unfortunately for good.

Still, I'm going to keep an eye out for an Elsinore. Hopefully, one day.

Depending on the quality of the restore, that's not a bad price, either.

Awesome thread and very cool stories and memories!

My first was a 1980 XL 125. then a 1984 XL500 with a large Acerbis fuel tank. Loved that bike. The 125 died shortly after we bought it when the piston broke, fell into the crank area and caused too much damage to fix. I can relate to many stories here..I remember racing through a clump of high grass, racing until i hit the boulder that the grass was hiding :).

The 500 is probably still running!

Thanks for the heads up. But I'm looking for one un-restored. Probably impossible at this point, but one can hope for a barn find. Besides, it's not a cool bike unless you build it
