I am having the same issue. Ran perfect all day yesterday, grabbed lunch and hopped back on...... NOTHING, no spark. Swapped coils, still nothing. Check my kill switch and regrounded, nothing. This is my first 2 stroke bike so I am not familiar with the wiring but it looks very simple. I purchased it from a guy you only had it for a month, who he purchased from a member here. Bike ran fine for the last month, no issues.
I am thinking CDI, but not for sure. Is there a way to check for this? The CDI reads "Banshee 1556", if this helps. Wiring harness connections are different from my buddies 1998, so I couldn't swap the CDI from his, if this is possible.
Mexicant-- Any luck?
