Hi everyone.
I have a 250 2009 Sherco and have had issues with the bike. I was in the middle of an event and the bike refused to start after the lunchtime break after riding no worries for the morning loop.
I checked the wiring in the bike and found that the CDI was in a bad way so I ordered a new one and fitted it to the bike. It was getting fuel and air so thought with a new CDI it was spark and that would fix the issue. I wired it all up and kicked the bike, it started and ran so thought that adjusting the carburettor would have it purring nicely and I would be back out riding. Tonight when I went to do this the bike ran great, then after it was warmed up and taken for a quick run up the street it died again.
I have taken the sparkplug out and check for spark, it is once again intermittent as it was before with the old CDI installed (we have more spark now than before however). The bike was re-wired up and during this we checked the stator (pulled it off and checked every wire which gave good resistance readings).
I am at my wits end and unsure where to go from here as with stator appearing to be fine, and a new CDI the spark shouldn't be an issue. I have been using brand new plugs in it over the last two nights when the bike has been running again. It is mixed on a 80:1 ratio and has also had the carburettor taken off, cleaned and blown out with compressed air
Any ideas on what the issue could be would be very much appreciated.
Cheers
Aaron
