UPDATE: So the weak spark is actually normal for sherco. It bridges 9mm from HT cable to frame. I tried to pour some gas directly into the bore, installed the spark plug and kicked it over and it fired right up. So it is an carburetion issue. Thanks for all the help.

Hi Geoffrey, do you know what was the issue? And if so how did you resolve it. I am having a similar issue but it did run perfectly, switched it off, removed the tank, put it back together and it has no spark. Thanks for replying in advance

Hi, sorry for not responding, was away. We bought a pair but different makes so that is no help. I have read the sherco lost spark thread but haven't seen the conclusion. I have tried several spark plugs and it is not that. Some local electrician repair man have told me that if it's giving spark (witch it does but it is weak) it is not the CDI/Coil problem and I should check the alternator voltage. Could you send me the values or the service manual, I have no leads. Thanks for all the info.

Also the case has no timing mark.

Today while riding I noticed leaking fuel hose, so I turned around and went home to change it ( the bike was running perfectly). I unmounted the fender and the tank, changed the fuel line and put everything back together. To my surprise it is not starting. Pulled out the plug (brick colour) and tested for spark, it had none. Checked the killswitch but that is working fine, cleaned all connections and still nothing. I did not touch the wiring when I changed the fuel hose. When checking the killswitch I measured around 13.7V so I suppose the alternator is all right. When I put my finger on the spark plug wire end I can feel a slight tingle. No idea why it would stop working so spontaneously. Please help with some ideas.
