Check to see if you have spark in both cylinders
Most likely the coil/spark plug boot connection

Cut your pug wires back some.

There is spark on both plug but not so strong

Remove your plug caps. take a set of fine point needle nose pliers and tug on the strands of the plug wires. If any pull out, cut back 3/4", tug some more. keep cutting back until you cannot pull any strands out. What happens is the strands start breaking. It will still pass current, but when you start riding, the ski starts moving and the plug wires bounce. Causing you to loose some spark.

Hit up OCD or you can do it yourself. I would go with OCD. But try what I suggested first. This quick fix may get you years of use.
