Mine does this if the air filter is dirty. give it a good clean or a new air filter and see if it cures the problem?? try the easy things first !!!

Hi all, I just wanted to tap into the collective knowledge of the sherco contingent here on trials central as I've recently acquired a 290 2010 model which is in good order, with quite a few upgrades, including an ohlins rear shock,hebo footrests, frame guards and a jitsie lanyard kill switch. I was wondering what the value of it might be as I'm considering selling it as it's not really my cup of tea. I took it in PX against an enduros bike so don't really know what it would be worth. And looking online there aren't any 2010's for sale to give me an idea. I know the ohlins shocks are not cheap and I also wondered if it would fit any later models ? Or is it only suitable for the 2010 as I'd considered selling the shock separate. If I could get a standard one back as part of the deal. Any advice would be greatly appreciated. Thanks

I found a link to a 2002 manual here - http://dl.dropbox.com/u/28069907/Montesa_315R_02_2002.pdf

I struggled to find one online but eventually came across this link, it may help someone in future - http://dl.dropbox.com/u/28069907/Montesa_315R_02_2002.pdf

Hi Guys, Just a quick one to day thanks for your help and advice regarding my difficulties with the Gasser, I spend a few evenings sorting the problems and we were out yesterday and the bike ran as sweet as a nut !!! after some fun and games de-coking the exhaust and repacking, it's now like a new bike, we just need to teach the rider a thing or two now and all will be well. So thanks once again for taking the time to assist, your help is Mucho appreciated. Dave

Hi Jon, Thanks for your speedy reply, I didn't notice that the carb bowl would catch the casings if I removed the spacer, but it makes sense now you say it, my mate is just getting back into trials after a long lay off, so he's not in need of ultra sharp throttle respose and wicked torque etc, I'll be leaving the spacer firmly in place !!! With regard to the head o-ring, I will pull the head off tonight and take a peek, I assume I should see some evidence of the leak?? even though the bike has hardly run since this occured I assume it will have left some tell tale signes that it's gone... As for the oil filler, I thought If I could not find the filler cap, I would lean it over and pour it right in the clutch directly, would you recommend any particular oil?? the oil in it is PINK !!!! I have ridden for years and never seen pink oil... I was thinking of popping some Putolene light gear oil in it like I used to put in my Mont 315R, it never did it any harm..... also seeing as you appear to know your stuff, do you know the fork oil weight and capacity for this bike as standard, I was going to go with 5wt as it feels a bit unresponsive at the front to me but I am not sure of the capacity..... Thanks again for your help.

I have been fortunate enough to get lumbered with servicing my mates bike, it has a few issues, mainly around being choked up and overheating like a good un !!! It resembles a steam engine more than a trials bike, but I currently have it in a million pieces and have a few questions that I am struggling to find the answers to, I thought that the power of the internet may come to my rescue once again and that I would ask the questions on here for assistance from people power. I have stripped the bike to allow me to de-coke the exhaust system, and whilst doing so I noticed that the inlet manifold on the bike has a spacer between the reed block and the crank casings, I wondered if this was a standard item, or an aftermarket spacer presumably to soften the power?? If anyone has a bike of the same type, can they take a peek and see if they have the same?? Also, I am not sure how much engine oil is used in the bike, I have looked up and find conflicting advice between 650 and 750ml, can anyone clarify?? Also, where do you pour the oil in??? do you remove the oil level window / bolt??? Forgive me if I am being stupid, only I can

Hi, I have had this before with a road bike, I pulled the forks apart, so I could roll the stanchions on a flat surfave, I used a pane of glass and looked for a gap appearing along it's lenght as I wolled it, much the same as you would do with a snooker que to see if was bent on a snooker table, the forks are easy enough to pull apart, so don't be scared if you have not done it before post a question on here for more help with that. I am not sure if the bike you have has one fork for the damping and the other for the spring as you do not mention the year (and I am really a Montesa man.... no spitting please), in which case, one would be easy to compress (the damping leg) and the other would be hard to compress as it has the spring in it so don't be fooled into thinking the legs are bent because of the ease of movement. I would pop the forks back into the clamps but don't tighten them, don't refit the mudguard stay and see if the axle lines up correctly, you may need to compres one leg to get them lined up vertically, however you need to be more worried about the horizontal alignment, this will give you an idea if they are well bent, as the axle will be quite a way out. also, look for any signs of visual damage on the stacnchions, they tend to crease if you have given them a real whack... I hope this helps. Dave

Hi Bradders, I am based in Dinnington sheffield 33 years old and been riding trials since I was 7 .... and I am STILL Rubbish, however I am sure we could learn a thing or two from each other, if you are interested in meeting up for a day, drop me a line. Dave

I believe its a engine split job... and ensure you get the washers back in the right places for the gearbox shafts etc... or you will have to split it again..... (voice of experience talking) I guess thats not what you wanted to hear....

Hi, As a previous owner of a 315, as I remember I changed the standard 40 tooth rear to a 42, (exactly the same as dropping the front from 10 - 9 asanyone knows) I found that slowed the bike down a treat, and also made first gear about useless, but you could ride 3rd gear a hell of a lot more !!! As I remember but of course could be wrong, I think the 98 & 99 model came with a 40 tooth rear but the 2000 onwards came with 42?? not 100% but I am sure Lurchio the closet Montesa anorak will help on this if he managed to get back from Macau....

Its also worth mentioning that the Right hand leg deals with damping, so the left leg will never feel like the right one as it does not have any adjustments or the same action. you'll notice the compression adjustment on the Left leg an allen key. with the damping adjuster knob on the right... As I remember...

Hiya, I popped a set of Boysen Reeds in my 2002 315 and it made the engine so much crisper and cleaner revving all through the range, as I remember they were about

Hey Lurchio, First of all, good luck in finding a 'vintage' Gas Gas, to the best of my knowledge all the 07 - 08 Gassers will either have been broken down for spares, or popped in a glass case for 'viewing' purposes only. If you can convince the owner of a glass case one to part with it, I suspect you'll just need to renew every bearing, seal, suspension bush, swing arm pivot, re-pack the silencer, pop a new water pump in, piston & rings and possibly re-polish most of the alloy parts, and then I guess you'll have a solid 3 weeks of trouble free riding (assuming you only want to ride around a club trial on a sunday following your lad and not actually compete). They are becoming almost as historical as a Montesa from Sandifords.... but without the HRC reliability or build quality.... just take a look down the gas gas forum page to get the answer....

Does anyone have a copy of the section analysis from 2008??? or can anyone point me to a link i would appreciate it.
