Sherco 290 Trials Won't Start?

Featured Replies

Hi there,

I was out riding when my Sherco stalled on me. I started it no problem but needed to keep the RPN's high to get it back to the car. When the RPM's dropped it stalled. Now it flat out won't start as if its not getting gas? I pulled the in line fuel filter to see the flow and there is plenty. I changed the spark p[lug. Still no luck? Do the fuel pumps on these go bad?

Any leads would be HIGHLY appreciated!

Thanks....

Ya I actually just did that straight to the carb bypassing the fuel filter. No luck....

Is spark plug sparking both outside and inside cylinder.

Need for high RPM to keep engine running can be a sign of air leak or source coil failing.

Thanks everyone for the tips. I have not had time to troubleshoot but I hope to find some this weekend. I will be sure to post my conclusion once I find it. And Copemech its a 2011.

Have a great weekend!
