The engine oil will tell you if the waterpump seal has gone but not the headgasket, its a two stroke remember. did the electric fan work ok ? coolant can drop if you over fill them as you are supposed to leave a slight gap between coolant and the top of the rad to allow for expansion. try a new plug cap andf check that the wiring hasnt been hitting the cylinder

Andy there are some things I just cannot accept. COTA KID is not a geordie, he seems a canny bloke when I met him recently but he's from Teeside. Geordies are from Newcastle or more generally Tyneside and are known to say Whyaye, you got that bit right. have a canny christmas hinney

Might be a good time for the 4T brigade to wake up. The 4RT is too bl**dy loud. Sure the emissons are reduced but the local church probably doesn't appreciate the bark of a 4RT on a sunday in quite the same way as Cota Kid (mentioned on another thread). Nothing against Cota Kid but noise is one of the issues the sport must address and its about time people stopped accepting that the 4rt is quiet at tickover as some sought of justification. If the bike produces less emissions but we lose the land due to the noise what exactly has been gained ? The other manufacturers are bringing out four strokes as well but how many are easier to ride than the two stroke? I still dont understand why the manufacturers / FIM dont focus on improving the emissions of the two stroke ?? and i really don t get why some of us are so keen to see the death of the two stroke at world or local level. Honda have always liked to have four strokes in trials (eddy lejeune, saunders etc) but i'm quite happy for Cabby and Raga to stay on the two strokes and for the rest of us to pay

Yes, My dad was importing them at the time so it wasnt an option really. the airfilter intake was by the coil under the tank so you had to be up to the filler cap to drown one. really handy feature that year !!!

The year they had to re route from the parc ferme was 1986, my first year, I still dont know yet why I went back again. That was on the Saturday but the worst day was wednesday. I set off to Achallader Farm ( we went round Kinlochleven first) in my JPX riding gear (similar to Ellgren), I was wet through by the time I engaged top gear !! Nowadays we have goretex and its still freezing It was somthing like 25 miles on the road. A lad called Roger Clark pulled into the NE Centre fuel check, when he stopped he was apparently so cold he couldnt move his legs so promptly fell over still sitting on the bike The sections were just unreal you could hear the rocks rolling beneath the water and picking a line was impossible. The year Rob Crawford jumped the river must of been 92 which was also very wet, I think he first rode in 89 so he couldnt of been there in 86.

Yes peter quinn, Martin cant see your image but im guessing its an ossa jkt or petrol tank, our house used to be full of them !!!

Hey Motosinge that guy on the 349 Mont with Quinns MCS on his back is a fella called Peter McDonnell, he and his brother Geoff rode a few times. Quinns was my old mans business and these two were sponsored by the shop. cheers

Cubby currently trying to tame my 06 300. I got on with it ok at first and actually rode it as well as my 250. But then had a month off, now i'm back riding I find its just too quick. It had the thicker base gasket in when i got it so Ive now put a spacer between the reeds and the inlet. I'll let you know if this helps after sundays wrestling session !!

well you were on the right lines with girls blouse but to be fair to you your not alone. The std scorpa clutch is a lot heavier than the sherco. Try a bigger master cylinder and / or a longer lever to make the clutch a bit lighter. I suffered exactly the same with my scorpa but your arm will get used to it eventually

so just after the first broadcast of kickstart Rathmell , Lampkin, Vesty etc all got deals with Pepsi, Mcdonalds and coca cola ???? I dont think it made a great deal of difference in terms of sponsors. TIMP is right its the trials that are the problem not the external coverage. It doesnt matter who sponsored 99.9% of riders they wouldnt be able to do one section.

Doh ok i get it. Short stoke may not grip as well but because of the associated power charecteristics rather than the revolutions of the wheel idea. Must admit I got this idea from HRCs big bang 500cc GP road race bike. HRC changed the firing sequence of a V4 so that the interval between cylinders firing was greater, MCNs (Motor Cycle News) theory was that this provided greater traction. I'll leave MCN and HRC to argue over that one !

I dont know that he would be able to hang around that long before he was out of time, to finish in time he'll have to ride (he being non novogar superhero) the majority near his alloted number as he can only be 20 mins late and he's excluded anyway. What seems daft to me is that the good lads often have good numbers which makes the trial even easier for them. Dan Thorpe and Michael Phillipson ( nothing against michael or dan just an example) were in the last 20 or so entries at the travers and generally the sections get better and better as most are in slippy streams. So they ride the sections when they are at their best, and they are too good for the championship, then peoople wonder why they go round clean !

Rotation of the wheel will depend on engine revs and/or gearing, the stroke length doesnt make any difference. A piston goes past TDC once every revolution no matter how long the stroke is. true, a piston goes past tdc every revolution of the crank but its how far the rear wheel goes for that revolution of the crank i'm referring to. shorter stoke = higher revving = less torque (ability to pull higher gear). gearing will effect the ratio of wheel and crank but rpm wont (unless the crank length or gearing changes with rpm the ratio wil always be the same) . If you had the same gearing on two engines with different strokes side by side then the short stroke must turn the wheel a shorter distance for one turn of the crank.

Just my thoughts on this as Ive done a few rounds in recent years. The post above mentions the top five being close to zero, if they arent eligible for champioship points as they are too good then I think that s fine. Its important to remember that the non eleigible riders are effectivley guests riding out of class and should not be influencing the severity of the event by their attendance. In a southern trial why not put those riders to the back so that sections are harder for them anyway or in a northern trial put them right at the front. This would allow them to have a more challenging day and perhaps allow the event to be easier for the rest of us.

Just to give credit where its due Bernie Schrieber won the ssdt in 81 0r 82 on a 280 swm. Still the best trial in the world !!

All right leave him alone how about distance between gearbox sprocket and end of swinging arm is one issue (effect of engine weight) stroke of the engine is another issue ( a longer stroke engine will be less likely to break traction due to the number of times the piston goes past TDC per rotation of the wheel ) flywheel weight ( once you have the rear spinning you should be able to leave the throttle closed for longer to regain traction if the flywheel is heavier) back pressure through exhaust ( that popping noise when your engine is slowing down after being revved, similar to flywheel effect ) just two stroke ??? actual power ouput and also how smooth the power curve is . effect of rear suspension units ability to keep the wheel on the ground disregard tyre because in a back to back test you would have the same tyre on all the bikes. some combination of the above determines how a bike grips in my rather humble opinion............

there was an ohlins advertised recently on TC for a sherco

ill have to drop it off as i dont like people coming to the house. however my van is very expensive to run so delivery will be around

Great I have just the bike for you 250 pro May 06 V tidy !!

I now have my fourth Gas Gas Pro. what annoys me more than anything is people advising others to split the airbox and apply silicone to the joints. I did it on the first two and it makes hardly any difference. The muck / water / whatever else is getting in through the air intake, through the inspection cover, through the hole in the base and through the bolt hole for the rear mudguard. Some may also get in the joints if you dont silicone them but as its going to get in everywhere else i dont see the point. Most of it comes in through the air intake as ; A its quite low B water runs down the joint between the tank and seat base C the vents in seat base are quite close to the intake Every trial I ride the filter box looks like a garden centre afterwards. We do have a lot of streams in my part of the world to be fair. However its very rare that anything gets through to the carb so dont worry about it. Buy good filter oil and clean the filter every time you ride. Also bear in mind that all the stuff in the filter box is still on the outside of the element. PS I absolutely love riding it

Oi keep it quiet ! its the first time i've rode it and we thought it was excellent (even though I accidently pressed the ejector seat button and sailed over the bars on one occaision). if you tell everyone it might get oversubscribed then we might miss out ! Thanks to Bill and everyone else involved

O level maths, add some things up , take some things away some people call it accountancy but I'm not trying to kid anyone !

Andy if you have some feeler gauges the maximum wear is 4 thou, (measured at the lower part of the barrel) any more and it needs a re bore. Scrape the carbon off the top of the piston anf it will be stamped .25, or .5 or .75. there are only 3 oversizes available so if its on .75 you can either get it converted to 270cc (ring Birketts) or get it re sleeved. You need to find somebody you know will do a good job for the rebore or you'll be no better off after its bored. You need to get it bored to 1 thou clearence of the piston and then run it in very carefully. try your local bike shops, if not Birkett is your man in my experience.

Given richmond has some of the best trials land in the country it makes you wonder why they went back, assuming they did of course

its original Cota Kid I'll give you that. I've stopped having a bath because I kept falling asleep in it, quick shower and then scoff some grub and drink a few gallons of water.
