We ran internal combustion engines on gaseous hydrogen in college and found that the flame front was extreemly quick and we had problems getting a full combustion on each stroke because it just wouldnt mix enough in time. Nice thing about gasoline or alchohol is that they burn slow in comparison to other fuels. With direct injection we could control the flame front but blew holes in many a piston. If you get the timing down it might just work but keep your stroke small don't expect a lot of rpm. It is extreemly hot when it burns as well as being volitile and quick. I dont know about 2 stroke but i know that it burns hot enough to take off any oil films which we had in our pistons and cylinder walls in 4 stroke applications.
Now a fuel cell powered motorcycle hmmmmm use some Ultra Capicitors and you have something there...
I was wondering when somebody was going to do that.
Some background on the videos: They have been put together, for many years now, by Dale Malasek and Jim Snell. Dale is the Gas-Gas Trials importer for the U.S. and Jim Snell (shown in the videos) is the parts importer here and both know just about more than anybody on this side of the pond when it comes to the Gas-Gas Trials and Pampera models. In the 80's Dale used to make excellent Trials videos through his company "Action Video" (I have the complete set and they are just about my favorites in my collection of about 450+ Trials videos) and he wanted to provide his customers with some good information on servicing the Trials model, so in the early 90's, he and Jim got together and made some VHS Gas-Gas Owner's Manuals (before DVD times...). A tape was included with each new bike sold in the U.S. (and still is) and updated when necessary and eventually switched to DVD format.
Both Jim and Dale are past U.S. National Class Champions and Dale still competes on a regular basis.
Cheers.

Love your tech section Jon thanks for keeping up the good work. Many a gasgas have been serviced by myself with your help. Thanks again.
I have all of your entries printed off in a folder of gasgas that i use all the time.
ooooooooo and Citytrials is silent...... Its bad weather in chi town right now.... He cant be out and about.... it is almost thanksgiving but we know that trials is his first family... Will we hear a response????
Kudos ringo good to read your thoughts again. Gotta love the drama of a motorcycle related challenge.
I think we should have a "Pinks" trials episode here in the states. Ooo a pinks enduro cross!
I suppose Adrian will have to drop doing the GasGas camp now that he will will have to attend to a lot of Hottie Tottie Mont riders!
Yeah just like Ryan and Brad had to drop the sherco camp to start hanging out with those Hottie Tottie Scorp riders.... Probably not...
Adrian is the man when it comes to knowing these machines and having that he got what he deserves. A large company to believe in his business... I think this is great! If Montesa wants him to drop all other brands i would be surprised.
Looks like cdi up front under the rad. Thats a lot lower than the present ignition box.
If the air box is the same then the air filter should be a carry over.
My only wonder is if this thing uses mass air flow or speed density type of air flow management? hmmm time will tell.
I want i want i want!
Ohv versus a flat head does not bother me one iota. Flat heads have great torque and so what if they run out of breath. Who needs rpms in trials.
Atom dont count your chickens before the eggs have hatched. In detroit every body is building a 700 hp 10 second car but when it comes time to run they end up having a 200 hp noise maker infront of a used truck transmission that leaks like a siv.
You know ive been kinda bummed out that the trials comp forum is gone and that there is so little activity on this tc usa site. I really thought these forums could help grow the sport a bit but then there are those who try to tear one make of bike down. . All 5 makes are good, The one that happens to be talked about at this time happens to be the most popular bike in the USA. I find it strange that if they break down so much why do they sell so many. If i was a newcomer reading this forum id think trials bikes arent very reliable which just isnt the case.
here here!
Trials bikes last a longggggg time for the simple fact that most of us cant abuse them enough to cause any major faults.
Ride what you are happy with. Ride to be out there. If your brand of bike needs to be proven it will be in the woods.
Here is a couple more from that national. Man i still have dreams about the first one here.
I am 20 feet up with no place to land! hahahahaha oh man this is going to hurt!
I actually made that section the first time through.
Mitchell my roommate was my minder. He ended up getting dragged down the rocks on his elbows holding on to the bike.... He still complains to this day....
I have a buddy who rides enduro with one in a pampera. I rode the bike and it was ok. The major advantage he said is that when he falls over he does not have to restart the bike and in enduro when your pressed for time thats a plus. I would never put one on a trials bike. It was smooth but didnt come in till about 1500 rpm and i want that lugging power to be there when i twist the throttle. Some people i have talked to can not get used to the modern on and off clutch. If thats the issue your thinking of fixing then maybe you might want to look at the oil your using or chain tension.
No i was surfing around on their website and found it in their funny email section. I listen to them every weekend religiously. The boston accent reminds me of home...
I had this happen on a sherco once. You could even shut off the fuel and the damn bike would still run! We found that the crank bearing on the clutch side had gone and it was sucking oil from the case and running on that. It was easy to see once we pulled the case cover on the clutch side. When that bearing goes the crank and its mating gear will bang into the clutch gear. If this is your problem then it will require that the cases be split and bearings along with seals replaced.

Single in the Supermarket
Dear Click and Clack,
I was shopping at the local supermarket where I selected:
A half-gallon of 2% milk, a carton of eggs, a quart of orange juice, a head of romaine lettuce, a 2 lb. can of coffee, and a 1 lb. package of bacon.
As I was unloading my items on the conveyor belt to check out, a drunk standing behind me watched as I placed the items in front of the cashier. While the cashier was ringing up the purchases, the drunk calmly stated, "You must be single."
I was a bit startled by this proclamation, but I was intrigued by the derelict's intuition, since I was indeed single. I looked at the six items on the belt and saw nothing particularly unusual about my selections that could have tipped off the drunk to my marital status.
Curiosity getting the better of me, I said: "Well, you know what, you're absolutely right. But how on earth did you know that?"
