  1. They are difficult to put back in but I wouldn't use a vice or clamp. Just lubricate with silicone grease and wiggle the pistons in by hand, if they are in correctly they will slide in with thumb pressure easily.
  2. That's what I was thinking. Got some araldite today but I'm going to ring Steve from Bradford ignitions tomorrow to check before I glue them back in. I'm bothered about the positioning as how does the stator know where to fire at??
  3. Well lockdown is lifted and trialing has resumed. Was supposed to go to my first trial today but went to start the bike before loading up and I got one fire then nothing, no spark at all. Started investigating and removed the flywheel to find the sleeve and magnets inside the wheel loose. I can turn the magnets inside the flywheel. Has anyone seen this before?? Looks like its all just glued together and it's all separated but can I just glue it all back together? It's a 2010 with the leonelli twin map system. How do I set them in the right place for timing?
  4. Ive spoken to Steve at Bradford Ignitions who thought it was a stator fault, but after sending him my stator, CDI and coil for testing, he's unfortunately confirmed its my CDI thats at fault and is non repairable. Anyone got one for sale as I really don't want to spend £400 on a new one.
  5. Update. I've stripped it all down tonight. Woodruff key is fine, reeds are fine, carb is clean, I've replaced the coil with a spare. I'm beginning to think its spark related. With the carb off and no plug in, it turns over really easy, but I only get one good spark then maybe nothing for a few revolutions then intermittent weak sparks. Could it be the stator?
  6. Ive done that twice now with carb clean and compressed air. I've got a spare carb knocking about somewhere so I might try that. Would a sheared woodruff key cause it to not rev or start on the kick?
  7. Sorry its a 2010 300 sherco trials
  8. Right, after three years and two kids I wanted to ride my Sherco 300 Cabestany replica trials bike again so I had to flush all the fuel system out on the bike, rushed it back together and put the lines back on the fuel pump wrong way around, the pump outlet connected to the vacuum line. Didn't realise this at the time and couldn't figure out why it wouldn't start so parked it up again. Back to it 6months later and find the engine and exhaust full of fuel. Drained what I can and cleaned fuel system again but it will only start if bumped off. And when its started it will only idle, it won't rev at all. Could there still be fuel trapped in the crank? Would that cause my problem or could it be the exhaust after having fuel in it so long? Any help would be great, I really want to ride again.
  9. Hi all im going to look at a 2010 sherco cabestany replica next week and just wondered if anyone had riden one before and what you thought of it. Also is there anything out of the ordinary I should look out for? The bloke is asking £2000 for it, is that a reasonable price? It seems a bit steep to me for a 4 year old bike. Any thoughts would be appreciated
  10. Hi guys im dragging this threat out of the databanks! I need a spare wheel for my 2009 sherco 250 for peace of mind at a trial than anything else. Ive seen a few about for sale but for silly money. Whats the going rate for a complete rear wheel these days? If I can id like to get one same as mine with the black rim.
  11. Yep that was the problem alright. Running like a dream now. Little bit smokey perhaps but hoping thats just all the wd40 and carb cleaner thats been through it burning off!! Thanks for all your advice everyone much appreciated.
  12. Looks like your onto something there TLRMARK, I pulled the reed valve out at the weekend and one of the petals has snapped off and was lodged in the rubber boot. I think we may have found the problem. Ive ordered some new petals that should be here tomorrow, ill let you know how I get on.
  13. Well ive changed both crank seals and its still no better. The clutch side crank bearing does sound a little noisy and there is a small amount of play in the stator side but that wouldnt stop it running right would it? Any more bright ideas? Could it be the cdi?
  14. Yeh I took cylinder off and cleaned the crankcase out but not before trying to start it after giving the airbox and carb a quick clean to try and get it running straight away. I am also begining to think I may have goosed the bearings. I am going to try and replace the crank seals today to see if it is sucking air in through them. Oh and the stator and flywheel are dry and seem fine.
  15. Yeh one of first things I did was drain fuel and put fresh in tank. Ive tried two different carbs on it, one with brand new jets in it, with same results. Would it still run if CDI was bust? I did think that the spark didnt seem that strong tho hence why I changed the plug.
