I would say make sure the cable run has no kinks or just badly routed. Give it an oil too,I use 3 in 1, I assume the throttle is a domino plastic type and once they've done a bit work it's hard to get them really clean. For £15 you could get a new one. I'd try these before cutting. Cheers.

Try it with the filter in place,but clean it and very lightly oil it first. If it's ok then something must be restricting the airflow unless as you mention the main is too big? Don't know sizes off hand, someone will already have them on the site. There isn't any homemade rubber flaps over the airbox?

You make me hanker after the old day's when half a jar of engine oil to a gallon was my rule. Bikes didn't run very well though ate plugs and smoked like chippers. I've an 05 SY,it's happy on 70/80 ml oil per 5 litre using synthetic. I wouldn't say these motors are too oil sensitive as i've known others to run much richer mixes. Hope you've discovered the root of your problem. PS if it isn't give it a try with the mudguard off,some aftermarket filters seem too thick and restrict airflow?

Mmmmmm, How rich exactly? Be honest now. And what oil?

Disgraceful behaviour! Riders enjoying themselves at a Montrose Trial? Does Geordie know? That club will be giving away free soup and cakes next. Can't anyone be serious anymore?

Hi Matt. This always seems to be a popular subject for debate. To me 70ml of semi/semi-synthetic oil seems ballpark. Be careful to mix it properly. Never noticed any measureable differences in fuel types. As above says, keep the carb clean which means good filter maintenance this is a must if you want the bike to run well and last. Happy Riding.

Cheers jfc,we do work hard at it. The club is only 3 years old and in the middle of nowhere. Last year we had about 200 members and I think we ran over 20 trials. We,ve had over 80 at club trials and normally get about 50 entries. There's no pack drill,just turn up and ride,if your new someone will go round with you Seems to work.

jfc,I don't mean to down anyone, it seems to me it's just the way things are playing out. I deal with youngsters on a daily basis,at our trial yesterday I coached 2 youngsters before the start and took another 3 round with me. We,ve started loads and they get a great deal from the club Even to the extent of loaning bikes. At 49 you can't think like a kid,you can only do so much and hope it works.

I see where you're coming from Baldilocks. A few sensible changes to the bikes would sort a lot of problems out, Sadly everyone want's the" best "even though next to no one can ride them anywhere near there potential. Unbridled bike development is the reason the sport is so fragmented.

OTF,I really don't know if it's just a trials thing or I'm getting too old but getting youngsters to committ to anything let alone Trials these day's is hard. Times have changed and we live in a world where instant gratification is the way of things. This rails against trials as you need to serve a pretty long apprenticeship. When I started out in the 70s all I did was Trials and the lads riding with me were much the same. Now?I see more committment from over 40 beginners than a lot of youngsters. When I hear the well worn phrase youth is the future I,m beginning to question it..

I only jest,at our club I call them friends,

No, I bet they all belong to a club. It's def got derogatory undertones. Thing is the club I help run has a Clubman route. Used to be called the yellow route which was worse. Can't use it anyway as we use red and blue markers now. If my wife won the clubman route that would cause problems? Especially as she can't ride. Time for a committee meeting.

We're all Clubmen,sorry I want that word banned. Wouldn't swap my 280Sr for Bou's montesa.

If our trials were televised they would view like Mad Max meets the Tweenies. Good point though,the old Kickstart was a great boost for trials. The sport seems to have outgrown it , If only trials had a speed element ?.

Rabie,that sounds great,no doubt a few will convert to mainstream trials but I would consider that an added bonus. Our club tries to be pretty laid back having fun rather than worrying about scores and rules. As riders improve we lose a few to other clubs, as we only run novice trials that's inevitable. We always get more new folk to replace them. I feel this is the way to go,the populations getting older and fewer want to risk injury,older riders also tend to have more time and money. There's a lot of people out there looking for trials,they just don't know about it yet.

I would be reluctant to criticise the makers as we don't even make any bikes here. You don;t need the latest bike to be competitive. If you look after them you get very little bother. Insurance?,it's £17 for officials at our trials and about £4 a rider . Like the sound of a trials holiday park but the boss goes on holiday to get away from trials . Land sems to be a localised problem Agree promotion of trial by importers ,authorities is grim and the clubs have enough to do..

Wouldn't disagree with everything,but you may get the award for negative post off the year.

Up here we have no real problem attracting "older riders",kids are a different story. I find with kids if they have a parent that doesn't get our laid back nature they don't last. Parents start complaining about trivia then go off in the huff never to return. The kids are always great but if we do get any problems there always seems to be a parent envolved. The ones that mum and dad just leave them to there own devices are never any bother. Do other clubs come across this?.

The engines state of the art compared with the old Yam lump (real motorcyle engine) Thats the first thing most say"it's got the old sherco engine" underating I would say? How old's that Beta motor with the kickstart on the wrong side? Nobody mentions that.

IMO a truly underated machine. I bought one of the last 2011 280s . Steers lovely with bags of usable power and totally stable. The other makers offerings may suit younger "trick" style riders but for everyrone else I would recommend it. And the best bit is no high rent suspension linkage. I feel the importer hasn't pushed these machines because supply may have been tricky. Shame there isn't more about.

You really shouldn't knock any makers. Our track record in Trials machine manufacture of late is frankly dire. I have to admire these continental types that knock a half decent trials bike together in the back room. Wouldn't like to think what we would be riding if we had to come up with the goods ourselves.

I know of one because a lad just up the road has it. (125 With the Sherco motor) Only really a colour change on the frame and new decals. Says it's only one of two in the UK. As for the 2013 photo call me a slavering B%$£^&". I had a good look at it doesn't really look right. If you check out the Eastscotland trials site there may be a photo somewhere of the said 125 with the orange frame.

The word Budapest was mentioned in our coversation and how he came by the info is a mystery. If there are 2013 Scorpas in Blue/White call me informed,if not call me a slavering B$£%*£$. You choose.

Last night a pal showed me a picture on his phone of what he reakoned was the 2013 Scorpa 280. Came in very tasteful blue and white livery. He downloaded it with great difficulty when he was on holiday in Hungary. Anyone know more on this?

If a Beta frame cracked I'd think it would be tricky repair compared with the Sherco. These bikes are built to be light so no way can a maker build something that will stand repeated heavy use. Some riders would break an anvil so I wouldn't be pointing any fingers at particular makes.
