I retired my first helmet on an F11. They were not hurting for power. But I could have used some suspension landing that dune jump.

Haha yeah they pull hard for a piston port 250, especially without a true expansion chamber.... I would be scared to see what it would do with some porting and a true chamber....

Those are sweet! Haha Shocktower, got me on that one! I plumb forgot myself. I can sort of relate to you Grreatdog--I was out checking cattle one day on that 1977 CT 125 and went past my little motocross track. I thought, "I wonder if..." And just being the spontaneous kid I am, got a good long run at a 25 foot tabletop in 4th, and landed it perfectly I remember hearing a "clack" front and back when I came down though, as I suppose I am a touch big to be doing such on that bike at 6' 6" and 200 lbs!!! Stupidly enough... this is 100% true

Explore an alternative reality for playbikes...


My putters to supplement a street plated GasGas EC300... less expensive to maintain and operate than a current MX bike, and actually significantly improve riding skills.


Based on jse comments, got the 2002 Pro chassis for the quicker steering and lighter magnesium engine cases. The chassis was only made for 1-year and is a odd mix of parts. Currently weighs just over 145 lbs. wet.

Complete rebuild of engine top and bottom end. Installed S3 225cc kit, S3 Stars cylinder head with interchangeable compression insert (currently running high-compression insert), and GasGas UK flywheel weight.

Revalved (2-stage compression and rebound) and changed spring rate on Sachs rear shock. Installed shock upside-down with 4mm preload.

Installed Formula 'Factory' forks (adjustable compression, rebound, preload, and end-stroke) with GasGas anodized Ergal triple clamps. Installed ProTaper Hi bend SE handlebars with ProTaper Medium compound grips.


Completed restoration of 1995 JT35. Approximately 170 lbs. with a 327cc Big-bore motor: tons of torque, and will lug at idle, out climb most dirt bikes, and traverse a 6-foot vertical obstacle in the right hands.

This bike may have an interesting histor if built by Jon Stoodley AKA jse for Steve Darrow for the World Championship. Had cylinder head mods, and Keihin PWK carburetor.

If you aren't committed the JT35 will 'bite back' and either break your foot.or throw you over the handlebars.

Very linear power and more than enough torque to plow a field - just don't stall it while hill climbing.
I think the GG factory designed the GT35 and JTR370 like the Honda factory did with the old CR480/500. It's actually a competence test, if you can't start it, you shouldn't be riding it..... The 370 was quite interesting as it was a 338cc, high-compression engine but had "370cc" cast on the outside of the cylinder. I'm guessing the prototype was 370cc's so they kept the casting mold but they reduced the capacity after it totally flogged more than a few test riders...

I'm trying to remember if Steve rode that bike at the World Round at Donner, he may have. He was mechanically inclined and took extremely good care of his bikes. Steve was a big guy (an Assistant Chief fireman and in good shape) and he had a hard time lightling that bike off so he asked me to make some changes. I re-machined the combustion chamber, which really helped, and he said it was a lot easier to start and ran smoother with no loss of power.

I agree, the 35 and 370 did not reward the timid. Like Steve's 35 and my 370, they were great bikes for Donner at 8200 ft. altitude and we never had a problem with power loss. My 370 was stolen years ago and disappreared completely. Few of them were ever imported here and they are quite rare (if you see one, look for the "JSE" engraved on the cylinder and lots of one-off special parts). I told the investigating Sheriff deputy taking the report to look for a criminal with a broken right kneecap.......

One of the inmates, hmb, had a 234 lbs. CRF150F which she had difficulty picking up if dropped on a nasty single track or gnarly terrain.

We introduced her to Trials, and found her a 150 lbs. Sherco ST2.0 (2-stroke) from another inmate that was much less expensive than her CRF150F. http://advrider.com/forums/showpost....6&postcount=16 Once she realized the huge advances in performance and how much her riding skills improved; I don't think she's ever going back to the 'play bikes' offered to the mainstream.

There may be solutions for you, like this or this.

Trials bikes are awesome playbikes, unless of course you feel the speed. Even then, 5th or 6th gear can get you moving along.
