thanks for the reply Vinne, I'll inspect the connection around the carb. I'd like to avoid using silicone sealant if i can because i dont want to risk the engine sucking silicone in. I've decided to do a leak down test on the engine first to see if the crank seal or centre casing gasket is leaking and then i will move onward from there.

Hi guys, I am having the same issue and it’s driving me bonkers. 2012 290cc if I spray brake cleaner on the inlet the engine dies. I’ve put new inlet gaskets on and new inlet screws and it’s better but still doing it. anyone got a fix for this? I’m debating splitting the engine and changing the Centre gasket. would a fuel resistant sealant work better on the inlet rather than gaskets?

yeah im not really after softening the power etc

yes i read it and comparing to my current piston it seems that the gudgeon pin to top of the piston is smaller, so it will lower the compression ratio in my mind I will talk to chris at splat shop when he is back on wednesday, see if he can shed any more light on it, im all up for saving £40 but not if its a bodge

Hi All, Im rebuilding a 2002 290cc Sherco, I've noticed on the splat shop site that Splat shop sell an S3 GG 280 piston, which apparently fits, altho there is plently of caution, said piston http://www.splatshop.co.uk/s3-gasgas-pro-280-piston-size-a.html Anyone else used this piston? for an extra £35 i may just buy the standard sherco one Matt

Sadly Santa gave me so many I have to use atleast two in every post !! Copemech's mod suggestion may work with your previous attempt, Not sure I'm willing to drill the carb just yet.

Yes im aware moving the float may make the bike run weak, but if the float isnt closing the valve, the bowl is still full ! The dellorto carbs dont overflow because they have no overflow pipe, it just goes straight into the engine ! Guess the trick will be to always keep it bolt up right

Hi All, I feel like this a common problem, and i have done some reading and research, so bare with me. I have reset the floats as best i can, but when i lean the bike on its side, say to rest on a tree, at a 45 degree angle or less, it just pours fuel out of the overflow, bike is a 2011 Raga, with the keihin pwk is there anything else i can do? Its using so much fuel and i recon this is partly why

thanks, just the answer i was looking for

yeah loosened those, the cap starts to turn but then pinches, hense i thought i was turning the wrong part and wondered if it was a special tool that had to match the holes around the edge, but looking at that diagram i dont think it is

Hi all, Im strugging to disassemble the forks and then drain to change my oil and seals. I have a 2011 Raga, with 40mm Marzocchi forks, and im struggling to remove the top cap as it feels tight. Am i right in thinking you just unto the top nut in a conventional manner? with a socket and just undo? .. it felt as though it tightened up was all. the top of the fork also has little holes, so i wasnt sure if it was a special tool, but looking at the diagram, i dont think it is the 2006 servicing, on this site http://www.trialspartsusa.com/tech.html doesnt give me tons of info about this. Thanks Matt

My 2002 sherco has started to shed its tank sticker, So annoying ! When im sat at a queue i can press the sticker and petrol seeps out, so i assume im getting a leak somewhere. Either at the petrol cap seal or there is a pin hole in the plastic tank. Has anyone had this? im hoping its the seal go on the tank Cap?

So ! i sent the V62 replacement form without the cheque, saying i wasnt sure if it was registered but heres the info, and they wrote back and saying here's the reg plate, and send the cheque to get the log book, Result !

going to try this on my 1999 montesa, i havent included a cheque and am sending it to the enquiries department, guess we'll see what happens

thank you for the pictures, really helpful and informative

Thanks for the update bud, Would appreciate any photos you have of the final install, and whether you have spaced the bash plate away from the engine or not. Having just bought my 2011 raga, Im scared to go see if it's cracked or not.

After taking it apart, and re aligning, it now works great

Thanks guys, it almost died before I bought it. I will post a finished photo soon, I'm aiming for Sunday's trial !

Still lots to do, but we had to start it !

It's taken about four months but finally we have rebuilt and started our 1998 Montesa cota 315r. It's been a teaching lesson for my 17 year old brother and he's happy to say the least ! We've gone from bits on a pallet to a running bike Feels good to rescue a Montesa from the parts bin

Hi all, My 315 rebuild is getting closer to completion, However I've noticed the kick starter doesn't return and it's constantly engaged... I'm hoping once I give it a good kick it will disengage but im not so sure. ( I stood up on the bench and tried kicking it. I bought it has an incomplete project and im thinking the previous guy has put something together wrong, there's a video below; what do you think?

bloody hell, just bought a 2011 raga and have now seen this, great

I tried a few different methods but i'll stick with it. Ive had a 2005 Pro before this, but its quite different which is why I asked

haha, I know there wil lbe a technique, There was to my Rev 3. Just wasnt sure if this was the kick starter at fault, or my brain !! Think i'll take the casing off to be sure. but im hoping its just the technique

Hi all, Having ridden my new (to me) gasser yesterday, i struggled to start the darn thing most of the day. The only way to describe it was like the kick starter wasnt quite engaging, to be honest the only way to describe it was.. Imagine the kick starter has its own clutch and it was slipping, It was as if the engine wasnt turning enough for the kick... .. if that makes sense? Im suspecting the kick start gearing is worn or has the problem that i seem to be reading about. Does this ring any bells for anyone? Thanks Matt
