Update--Thanks again for your help lads-- I found an old pilot jet in my tool box so I drilled it out...just for the hell of it.. It really solved the problem-- made the power meaty at the bottom end. Instead of just messing around, practicing on a very,very small rocky section I took Cherie ( I name all my Shercos)to a bona fide trial last sunday ( It's been 10 months since I rode an event) . I think the longer run out has cleared out the exhaust. The softer power delivery made the bike grip on mud and roots much better than the 250 ever did-- now I get it (the need for the spacer). Cheers

Yep-- confirmed-- 2 of the 4 I've had were dribblers!--

On a similar topic... I have found that my riding has improved dramatically by emulating ( in a Geordie /Spanish style) the Spanish riders' and minders' utterings.. especially when delivered at hi speed:-- Quanto quanto!..seat alhambra!..heeho de pootah!.. you know, the sort of thing Raga uses to get out of a tight situation!? Try it

Easy-- I'm sure on all Sherco frames near the head-stock there is a plate which states 2% pre-mix. I've had four Shercos now and I run mine on 75cc ( fully synth) per 5litres of optimax which is less than the 2% stated. Shercos have a middlebox/silencer combined--if you use too much oil in your mix the packaging gums up and it is virtually impossible to clear them out successfully. As for your 'petcock!!!'-- point it down for ON-- point it left(out over)for OFF-- point it right ( in towards the exhaust) for RESERVE. Okeedokee?

Speaking from indirect experience-- it looks like you may be burning a little gearbox oil there

Yes go to Ryan Young Products-- there is a 2005 trials manual there

Could be a Yam tyz frame with a 4 stroke motor squeezed in there ! If I'm right do I win anything?

Paid

Not many redeeming features in my experience I got one given to me ( in a box, in bits and pieces)about 9 years ago. That re-kindled the off-road bug but I'm afraid the gearbox and the clutch were out of the frame more often than in! I seem to remember the steering was smooth and sturdy though.

Don't mean to be the bearer of bad news but.... I've heard of a few 04 shercos with weak spark problems.. just a worst case scenario thing. I owned a 250 '04 with a poor spark-- try closing the plug gap.The symptoms you describe for poor starting are the same as I had on my '04. Hope i'm wrong! it's been known before!

True story?

Yes! Some parts did make it to the outside world. I went to view a 2003 315 a couple of years ago in deepest Yorkshire. Along-side the standard 2003 for sale was a Titanium clad 2003 315 that the owner was very protective of. I begged/hassled my way to a test ride of the 'special'. The front end was lighter than the standard '03 'cos it had what looked like machined titanium fork legs and clamps ( the owner confirmed where these parts came from to assure me everything was above board).I lost interest in the std bike and made a very, very reasonable offer for the special..he declined..so I bought a Sherco!!?..I never said I was logical.

Thanks again for the advice fellas! I think the general consensus of opinion is to gain a little more skill on the bike. Skill?....hmmm... now where can I buy that from?

Yes Nigel you're right-- 250 for sections with rocks--290 for muddy climbs...but would anyone protest when I switched bikes mid-trial? There's a question.. does anyone know if Jarvis has his in or out..er.. spacer that is?

Thanks for the replies fellas. The reason I want to take it off is that the power delivery is too soft (just like you say) compared to my 04 250 (the250 p155ed up steps from stationary) . If I don't have to mess about re-jetting the carb then I will definately remove the spacer.Thanks again

Excellent info ...thank you.. we need more posts like this

Yes.. I find the people who use the phrase--''as different as chalk and cheese ''have obviously never tried ASDA's own brand cheddar......exactly the same taste..awful!!

This worked for my old montesa after trying to bleed it for hours and hours: Tip the bike up 45 degrees ( front wheel up the wall)and bleed it. Then tip it 45degrees ( back wheel up the wall) and bleed it.This is not a wind up

Hello scorpa people... anyone there??please answer.. To mis-quote Ali G : 'Is it cos I is Sherco?'

Hello Scorpa people--can you advise? I'm thinking about a SY250, hopefully '04 or '05yr. Does anyone know what the difference is between these models? Are there different SY250 models i.e imports vs UK dealer bikes,have there been any clutch mods? I remember trying Martin Crosswaites bike (possibly an 03 model )at a show- the clutch was a bit heavy and the engine was easy to stall ( I think he had the timing advanced).At about the same time I also tried another 03 bike at a trial and it was much easier to use..lots of low down oomph! So if you see what I mean: I like cheese but not chalk. Any opinions please

Toni Bou ?..I thought I'd drag myself to Sheffield this year just to see what all the hype was about Bou.I was expecting this apprentice to have a good go at some of the sections!! I mean I was a bit sick of the cynical show that Fuji displayed last year . I'm sooooo glad I went, that was the best Sheffield ever.Two days later and I'm still hoarse. The crowd and Crosswaite played their part . Raga tried to pull rank on Fajardo to put pressure on Bou in the final. Crosswaite and the crowd did'nt like that one bit ( credit to Crosswaite as I think he has a tie-in with Gas Gas himself)and they turned up the volume to encourage Bou. Raga let it all get to him on the waterfall- then he got brain-fade at the U-turn in the race ( I think it was a three/four/five-point turn). The best rider won at Sheffield. Toni Bou the apprentice?? shame on me.. Toni Bou the master!! As for Dougie?...I think it was Bou and Fuji who showed him the way to exit the rock section. Don't blame the bike-- HRC can't manufacture brass balls.

Use the hairdryer technique to remove technosel- I didn't and it pulled some of the chrome off my old gasser

god: you're not alone with the piston problem.. I don't want to say much cos my mate has to sell his bike but his 06 300 nipped up twice in a matter of hours. It all got to the legal/threats stage before GG agreed that the piston was too big for the barrel so yours was not just a one off

It's a common saying round these parts. Just means: I don't mean to tell you something you already know I didn't invent it ...honest! :hat:
