Where in the UK will rebuild my crankshaft?

I don't think there was contact with the head, it looks fine. The piston is scored and the cylinder has a wee mark.`

the play is somewhere around 1mm up and down. will buy the kit.

even if I buy a new bearing and the pin?

Sherco 290 My cylinder is off to get replated. The conrod kit at £210 looks pricey if the conrod is ok. There is play at the big end, how would I know if the conrod is OK to reuse? thanks

I had cut some nylon strands off the kitchen brush, so the poking was not very violent. What I have learned today is the Pilot hole in the carb does not go straight to the tube that sits in the reservoir, there is a wee dog leg. My bonus learning is not to leave the jet hanging by a few turns when it is in the kitchen to take a picture. Somewhere between the front door and the shed it unscrewed. Spent longer looking for the jet than cleaning the carb.

thanks, I now know that when looking from the bottom it is the pilot jet that leads to the black bit. Will now have a dig on the link, ta

Cleaning the carb today. There is a wee black circle above the hole for the main jet in the picture on the left. It is blocked, but maybe it is supposed to be. I have given it a gentle poke and it feels as if it should be there, but it could just be dirt jammed in. My finger is on the screw that leads to the black bit. It is a PHBL26 The bike has a good spark but is harder to start than it should be. Dirt or that is what it is supposed to be like? thanks

I had a spark this morning, I went a wee spin. Later my friend went out on the bike and he said it was like the fuel had ran out. He gave it a kick, it ran for a bit then it happened again. When we got it home there was no spark. When I did the above test 1800 was the reading I got on both wires. Is this so high that I would get no spark? We went up a stream yesterday, but there was no water or wet look when I took the flywheel cover off.

the silicone gasket was a bad move,it did not set, it is not supposed to. I cleaned it off and used some general kitchen silicone to glue the bits together. Started the bike tonight, running better. Now to fix the other things it needs.

Yesterday I made it down 10mm and saw no sign of a spike. Today I turned down a piece of steel to fit in where the cable went and drilled it out , M3, and cut a rudimentary tooth in the end. Put my home made bit in a power drill and went down to 17mm from the top of the fitment in stages. 7mm of spike was visible. The was some white polished looking plastic at the bottom so I did not go further. It is now sitting in the shed with some silicone gasket holding the cable and the cover in place. Tomorrow I will put it back on and see if there is a spark again.

Hi, I had an intermittent fault, which I have fixed by making the fault permanent . I have just got a 2006 Sherco 290 and the HT Lead had electricians tape on it. Sometimes while out it would not start, even when warm, then it would. I figured it was the HT lead. I took the old one off and sure enough it had been patched up. I had read that with patience the Lead can be dug out at the CDi unit to reveal a spike. I dug in about 10 mm and did not see a spike. Plenty of copper, so I bared some wire on the new HT Lead and pushed it in, securing it with tape. No Spark. How far in do I have to dig to find the spike? this is the one I have http://www.splatshop.co.uk/sherco-07-c-d-i-box-leonelli-short-cable.html thanks

Back again, what should I set the torque wrench to to tighten the flywheel nut? ta

thanks ever so much, I think I can manage now, I will be back if I need help.

Beta TR34. There are two adjustments as far as I can see, the motoplat has slots where it gets attached, and there is a plate behind the motoplat which has three screws which can also be adjusted. On this plate there is an arrow and a mark on the body. There is a 2.5 mm hole on the flywheel and the motoplat. There are pictures here https://drive.google.com/open?id=0B_U7i5Hd7WKpeUZDYzFNU2FEcHM My best shot is find TDC on a gauge, set the back plate to TDC, put the motoplat on and dont tighten the screws, put the flywheel on the shaft with the keyway in place and tighten a bit, use a 2.5 mm drill to line up the flywheel and motoplat and adjust so cylinder is 1.8 mm(?) before TDC. *If I cant get 1.8mm of play, go back to start and put first plate before TDC. is that it? Ideally I would like an easy kick start, what timing for that? thanks
