of course... Its the only name that can afford him although Id love to see him ride the 4T with Cabestany too

Gotta agree with yer there mate. Caby rides that bike like he was born on it..

Did you try the 4t ? Much more power available

Nope! I reckon between the 290 and the 4T, its easier in the mud on the 4T. But, thats my opinion.. like to hear from a more experienced source.!

I got a Sherco 4T and have been told to use smoooth throttle and no blipping. After trying it, it certainly helps and grips better than the 290 I had before. IMHO

Theres a bit of work to do setting up the program on your comp like producing the custom sort lists and creating the custom Macro buttons and then building the database of your clubs riders names & details ( although you can do this as you go along ) I can provide details on how to do this with the spreadsheet.. But its best that I talk you through it using MSN Messenger.. My MSN is viciouss@mods-r-us.net . If your currently typing in all the data and doing manual sorts and stuff like that. This will save you loads of time and when set up, is easy to use. feel free to contact me

That is one awesome Machine that is.!! Woah.. In fact theres TWO of them!! O, by the way.. great truck too Howard

You just answered your own question! Oil pressure fed systems are a must for racing engines. Not the case for a Trials bike engine where for most of its time, its hovering around 1500 rpm . Now can you stop going on about the virtues of the 4RT's pressure fed system vs the 4T I believe that the 4 stroke running hotter is an illusion to a certain degree. The temperature in the combustion chamber would be similar to other engines.( I will research this) After all, maintaining a consistent temperature will aid the efficiency and performance of the engine and this must be in mind at design stage. If the barrel was overheating then the water would boil but this doesn’t happen. What you do experience is that the engine in general is hotter on the outside due to more moving parts ,its thermal mass being much more than a 2 stroke and the fact that heat is not dissipated fast enough.( as mentioned above in another post ) a greater surface area to allow for heat dissipation would help (like air cooled fins. ) although air is a bad conductor of heat. Water is much better having the highest thermal conductivity of any liquid. IMHO

Interesting comment Woody. Why did you buy a 4RT bearing in mind so much negativity was being spouted about it. It does seem that people are too willing to condemn either through jealousy, prejudice or ignorance. The only thing that does is put people off the sport. Im happy with my 4T and your happy with your 4RT. Couldn't give a damn what anyone else thinks to be honest.

Not 4 strokes per se, just the 4T . Often by people practicing sciolism I welcome the use of fuel injection and hope they develop it for future generations of Sherco's. After all, electronic fuel injection is tried and tested technology since the 1980's. Hardly anything new there. but saying that, the carb works fine and its all technology we know. Goes without saying.. and to date.. I have no reason to believe the 4T isnt just that. Sure was a good trial. Yellow route was spot on . It was damn hot on the top though I can tell ya.. Poor ol' Inky & Kirsty observing up there .. Matrys to the cause bless em

Are you 100% certain that sherco and not using an internal oil pump?

Only extreme because it was tuned for racing. Consider a toned down version. ! The engines are very light, lots of power and smooth delivery. Even less moving parts than a 2 stroke! why not develop one for a trials bike? sorry, I know its off topic, back on topic now

One other key factor in heat generation is the cylinder compression ratio. ! If its high then a significant amount of heat is generated just in compressing the gases. Try taking a cycle pump and pumping it a few times in free air. then close of the end and pump it. The heat that you feel is mostly the friction of the gases being compressed (With some piston friction also of course) Also, the extra force also places a greater load on the bearings which in turn, increases the level of friction again generating more heat. Obviously then, if you minimise friction, you have a cool engine

Nice to see your a 4 stroke fan so you cant be all that bad The 2 stroke engine is still a remarkable engine.. but for sheer design, the best engine has got to be the ****el rotary engine ( except for the rotor tip wear). Would like to see what one of them could do in a trials bike.. They rev till they blow! Edit: Lol.. posted this then noticed that Dr Felix had his name bleeped out if you want to see an animation of a rotary engine then type this link in http://www.keveney.com/****el.html replacing the four * with the correct word as this forum edits it out.

Ive had from new 2 problems with my 4t. One which was resolved quite quickly and one which is getting sorted. The first being the fault with cables coming from the generator being too tight and chaffing on the sharp edge of the casing. Thats been replaced and smoothed off and now no problems. To be fair, this shouldnt of happened as its obvious to any engineer this would be a problem! The other is the starting... However im a lot better at it now than when I first got it. A decent bit of instruction from Sherco in the form of a comprehensive Handbook wouldnt have gone amiss!! Otherwise the bike has been faultless in all respects AND a very enjoyable bike to ride. My wife worked for a peugeot dealer for 2 years and the amount of faults on new cars was staggering. I know theres more to go wrong on a car but we are talking about a HUGE company with HUGE resources! My only gripe is the lack of a decent Handbook and Manual. After all CE certification that I have to follow when I design a machine that gets shipped to spain requires a full and comprehensive manual in the local language to comply! Why doesnt trial bikes have to comply when they are shipped here?

ahh, that be the curse of MSN Messenger Peeps is short for people

http://www.trialrace.com sell stuff. You can use the google translate feature to read it in english. I looked at some gaerne boots and it says to buy stuff , email direct to trialrace@trialrace.com Cant find anyway of buying stuff from http://www.toptrialteam.it/ sorry !

if your refering to the italian site http://www.toptrialteam.it/ then No. Its just a basic flash site. I'm bemused at to what you think you can buy there

Hmmm. Have you tried that with your Windows operating system ?

Thats gonna pee some peeps off and make some others very happy! What will happen to the world round next year? will it be totally 2 stroke power again?

I have a 4t and ride the clubman routes. I have found moving from the sherco 290 that i can do everything and more on this bike that I could do before, but with a lot less revs. I havent found it necessary to rev the engine to peak revs in any section I have riden as yet. Also, my scoring has dramatically improved in the short time I have had it.. just ask Elwyn A local rider in Llanfyllin trial I rode on saturday had a 4rt and we swopped bikes for a little while. I found his bike to be quite revvy in comparrison but it certainly rode ok. The 4t certainly has more low end torque and pulls through to mid range without any effort whatsoever Im not knocking the 4rt, Its just not to my liking but other peeps like them so its personal preference. IMHO

what you mean like the Sherco 4t
