Done another plug tonight??????????????????????????????? mate of mine had the same problem earlier this year, new Mikuni solved it, think i will stick a new carb on next week and try it out. Great time at the quarry today, few offs from most of us and a spectacular loop out from Ralph at the end doing a third gear wheelie, that stubby thing that sticks out on the right hand side is the rear brake mate, it helps having your foot over it before you nail the throttle. Mike Johnson showed us all how it should be done, and no doubt will do again on Sunday in Wales,
David, as neon says bhp has just about nothing to do with trials bikes, what you need is torque, the 85cc crosser has more bhp because it revs high at the expense of torque. If you look at the crosser torque spec bet its got next to bugger all. There is a calculation of torque/bhp and rpm but cant remember it now, you cant have big bhp,big rpm and big torque without a massive engine. If you want something to bomb round the fields get a crosser not a trials bike. Its the same for Ducati's and Harleys, bugger all bhp and revs but bucket loads of torque, Jap bikes lots of rpm, lots of bhp but not as much torque, cant have it always
Well done Shaun, great ride hope theres more to come??????? or will he p*** the team off as usual!!! anyone see him wobbling about on the podium, must be a big weight disadvantage dragging all that beer around Croft. Hope he does shine in the 600's still a good rider, but have a feeling the demons will return and this will be his last year in the British Championships
Phil, depends what you are riding over really, if the shock is bottoming out over medium rocks, logs etc wind it up untill it isnt. Does nt want to be to hard so it does nt travel much but needs to use as much of the spring as possible without bottoming on most stuff. The rebound is up to you, if you want to hop around alot it needs to be springier but not so much that its like a pogo stick. Front and rear suspension should work together as well, push the bike up and down near the seat and see if both are working at the same rate or near to it. You may find you need a stiffer spring than standard which can be bought without too much trouble
If you ve got the certificate of newness for the bikes get them registered, not that difficult to do and then you can get easy and more cover for insurance like a road bike, should be cheaper as well. Could even do the road trials which are generally better events without trying to outrun old bill when he pulls you over for a check. Not looked into the pure offroad insurance policies but I bet they are pretty limited in what they will cover if the bike gets pinched
Thumper, I have found the gearing on the rev3 about right, first is low but make it sing abit more and it will go up most stuff you think you may need 2nd for. Second can be a bit quick and I only use it to go bigger stuff and not for tight flat turns etc. The 270 will pull 4th and fifth on climbs and I have never known any bike to grunt up hills like it. I have dropped the forks through the yolks to raise the front and stiffened the back abit as I found the standard setting to soft. As Heath said a fast action throttle is great on the 270, it can get you out of trouble quickly in a section and get you up and over things from very short run ups. Lots of people say dont fit one but I could nt ride without it on and I m no expert. If you ride streams and rocks may be worth keeping the flywheel weight on as the beta is a bit savage on the rocks without it . Get a float bowl extension and i have the fuel screw 1 and a half turns out from fully in, this is adjusted though depending on the weather. I have nt done much to the front end but have pushed the bars forward which seems to make the front grip alot better and not wave about whilst climbing.
Cheers Heath, product testing for the site, good idea and freebies, let us all know what they are like once fiited either way. I bet they will make a noticable change to the running
Barry, you are fast becoming the Seth Enslow of the Trials world, few more months of pics like that and you may get sponsored by Repsol and become head of R&D with Renthall
Sure do mate, and the other one about half hour away. One of your lads told us about the bank holidays and the raves thanks, never had any trouble with the old bill, quite chatty sometimes I ve heard.One of the lads was on a sherco and from Tredegar if you know him. Try to go to Wales at least once a month if possible, well worth the two hour drive. May see you up there one day?
Should have been nine of us out today but a few did nt turn up, pic is of 4, 06 270's and a Cabestany rep, should have been 8 Betas instead. Fantastic day, rode for 8 hours nothing stupid just some great sections and a good laugh. Met up with a couple of local lads for an hour or two on Shercos, dont know how lucky you are living with this lot in your back garden. About 400 Enduros there again, but no burger van this time unfortunately. Bike rode really well and no popped plugs so maybe the resistor in the plug is causing the problem after all? Hoping to actually do a trial somewhere next weekend, anyone know where a good one is on aprox 70 mile radius of Oxford.
