Hi everyone,
So, a friend recently brought over his 2011 Sherco ST 2.9 as it wouldn't start. Vacuum and fuel hoses were in no good shape (or let's call it nearly non-existent), Replaced it all and cleaned the carb while I was at it and the bike started fine without air filter and while spraying some brake cleaner into the intake hose and then kept on running fine on its own. Assembled it all and again it won't start. I tested for a spark, but it's very weak and seemingly only one every few kicks. No change to that with another spark plug. So, before I start ordering all parts that *might* be causing the issue (he needs the bike back by next weekend if somehow possible), I was wondering if there's a common issue that I might look into. I thought about CDI, ignition coil and cable, hall sensors, stator... To me it sounds like an issue specific to the starting routine as it was running fine after we got it started with the brake cleaner. I don't really know much about Shercos, used to ride Beta 4 stroke and am now on a Montesa , so any help would be greatly appreciated.
TIA.
