:huh: :huh: Nice one.

From Wikipedia: Compared to piston engines, the time available for fuel to be injected into a ****el engine is significantly shorter, due to the way the three chambers rotate. The fuel-air mixture cannot be pre-stored as there is no intake valve. This means that to get good performance out of a ****el engine, more complicated fuel injection technologies are required than for regular four-stroke engines. This difference in intake times also causes ****el engines to be more susceptible to pressure loss at low RPM compared to regular piston engines. And your point is? Why I think a w ankel engine would be suitable for trials is :- [1] You can get a large amount of power from a small displacement. An RX8 has a 1300cc engine and pokes out 220BHP (if I remember correctly) [2] The engine could be quite small [3] They can also rev very high [4] They have a considerable smooth power delivery. I took an RX4 to bits once - amazing engines It would require you to change your riding style i think, when you have an engine which might rev to 20,000rpm, but the weight advantage is certainly there.

i havent ridden an RE5 but I have a mate who has a norton rotary (well several actually). Those engines are seriously good. I don't know of any that have been built small enough to fit in a tirals but theoretically there is no limit to how small they could be made. I imagine a 125 or 250 is quite possible and when you consider that they put out a remarkable power for displacement a 250 rotary would have about the same bhp as maybe a 400 so a 125 would work fine. Not sure how much they would suited to trials though as i beleive you dont get as much torque from them. I really struggled to get my head round how they work until i saw this a few years ago:

Your probably right. I just copied it from an email i got. Thought it would be funny.

Does anyone know the correct float height for my scorpa easy 250 (1997)? It has the keihins carb. Thanks for any info.

Hmmm. just been looking at the prize purse for the endurocross. According to the chart it says that if you finish 1st in all events the prizes are as follows: Denver first place $2,500, Oklahoma first place $2,500, Vegas 1st prize $10,000 and series bonus $5,000 which it totals to $21,000. Is my maths wobbly or is that $20,000 not $21,000

You're not North Korean are you? You wouldn't need the long range ones if you moved in eh? No, I'm in Lancashire U.K. but my neighbours are a mad scientist (no really he is, he's a physicist and he's genuinly bonkers) and his bargain basement russian wife. You get what you pay for, she is 60, very fat, like 30 stone, very ugly, cant cook, can't speak much english and physically pushes him around, she even knocked him to the floor once when he didnt agree with her. Dont get me started. I paid nothing for mine There's a joke there somewhere I think this is probably one for the anything goes section - admin's do your stuff Mmm. Thought i had put it in anything goes actually. Sorry. My mistake.

I had the same problem when i bought my 1997 250 scorpa. The bloke i rang said they were all the same and the one i fitted was suitable for gas gas and sherco. I may be wrong, can anyone else confirm?

I just cant figure out what you were searching for, and why, when you came across this I have some really bad neighbours and thought that if i could just find a trident missile on ebay i could blow them away for good, after ive gone away on holiday of course.

There is a classified section accessible from the front page of the site.

just saw this on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...em=190132455924 If only they would post it to me in the UK. It sounds like heaven. You could ride indoors in the underground tunnels and live there too. It'd be like being a real life bond baddie.

I love the smell of castor, reminds me of my yoof.

Excellent. :huh:

I swear by silkolene comp-2 Synthetic. I run it in my CR500 motard (at about 35-1)and have done for about 7 years. My mate runs the same oil, but in injector form, in his KH750's (he mixes a little in with his fuel too). He built a 750 that dyno'd at 103bhp at crank. he ran it for about 30k miles and then took the engine out and stored it for about 2 years. When he stripped it down not only could you still see the crosshatch on the bores but when i wiped my finger down the bore it was still coated with silkolene from when he last ran the motor. I know there are newer oils out there but i think it will take a lot to make me change from it.

I think that Copemech makes a very good point here. The majority of trials riders are do-it-yourselfers when it comes to maintenance and repair. I am decently mechanically inclined and if I have access to proper spares on the day of the event I can repair just about anything that may break on event day and continue to ride. The way the bikes are made now are relatively easy to diagnose the problem, if getting into throttle by wire now there are sensors, contact points, and more wires. if you crash in the water and the throttle is submerged what will that do to the throttle by wire? What I am trying to say is that the new technology is more difficult for the majority of riders to understand, the majority of riders are not 17-18 and totally interested in all things electronic. Majority I think are 25-50 and mechanically inclined. Just my opinion, and usually nobody cares anyways For me, I would rather have a reliable bike than one that's easy to repair. Both automobiles and motorcycles are far, far more complex and technologically advanced than they were 35 years ago...they are also incredibly more reliable. You may not be able to cobble together a roadside or trailside repair when something goes wrong, but that occurance is so rare, that I welcome the trade-off. If I submerge my bike in water, I don't expect the throttle-by-wire to be any more/less reliable than my electronic ignition. Personally, I'm not itching to get back to the days of points, condensors, magnetos and fouled plugs than I am to get back to the days of pilot jets, main jets, slides, choke circuits, floats, check valves, vents, compared to gas and go in any conditions. I have to agree with that but there is still something in me that cringes at the thought of oodles of computers all over any bike (expecially a trials bike) Just my opinion so its probably wrong.

The two stroke development originally came from GP racing of course, courtesy of MZ for coming up with the expansion chamber, later stolen by suzuki, literally. Its a pity that two stroke corporate development in motorcycles came to a stop in the 80's, Largely due to emmission laws. Imagine if the 2 stoke technology now in snowmobiles and jetski's came back to motorcycles. Not just trials bikes either. Imagine a 1000cc 2 stroke fuel injected in line four engine in a superbike. Lighter and more powerful than the present rake of jap superbikes. 250mph anyone? I dont think we will ever see the kind of 2-stroke development that took place in the 60's return.

Hi, Sounds like great advice but would it really be wise to have someone observing who has never been to a trials event or even watched one on tv (apart from watching the odd kickstart when i was about 10). Thats a good queue for everyone to take the p**s. I would be happy to be an observer once i have a clue about whats going on. I love burgers!!!! Is their any trials on tv these days? I have sky and all the sports channels.

Hi Thanks for that. I'll have a look. I'm a bit hesitant to enter an event until i get a bit more practice in. Its a bit of a catch 22 i s'pose. Ive never even been to watch one! Maybe that should be my first step. Thanks. Marcus.

Hi. I live in lancaster, lancashire and am struggling to find anywhere to ride. I fancy some greenlanes or something as i am just starting out. My bike is on the road so not a problem to ride to somewhere. I know there used to be some green lanes around the trough of bowland but i dont know if they are still open to bikes. I have been to Delph quarry but its very small. Good for a bit of practice though. Any ideas? Cheers

nobodies helping me. . . . . sob.

i just got a daytime MOT for my bike and aside from the obvious (wheel bearings good, brakes working steering head bearings good, shock linkage good, etc), you require the following:- Rear reflector. Horn (apparently for bikes newer than about 1990? this has to be electric and of a constant tone) I got one designed for a bicycle from halfords for

Sorry to have to bump this thread but i'm sure someone out there can tell me the float height for a 97 scorpa 250. Come on guys. dont make me charge you lot with with-holding information!!

No way!!! What excuse will small boys have for sniffing glue now?
