I recently started having a problem with my banshee cutting out on the right cylinder at mid to upper RPM range. It first happened while i was out riding with a friend, we rode about 60ish miles that night on dirt roads.
I went to make a pull from 3rd, through 6th, and at the top of 6th it fell on its face, much like a fouled plug, The cylinder went silent/dead.
I rode for a minute or two before changing plugs, And nothing changed. So i limped her home, Rode great on the low to mid end..
My first thought was maybe a spark issue? Swapped wires left and right, nothing changed.
It was suggested maybe reed valves getting weak? Wouldnt that be more of a low end problem? They feel tight and have no damage or cracks.
I pulled the carb (28mm Keihin PWK), seemed to be normal. Next step I think i should do a compression test on both sides.
If it matters:
'98 Banshee
Stock bore, never bored honed or ringed. (Starts on first kick after sitting for weeks)
Keihin 28mm PWK's
3/8''
Pro-circuit pipes
K&N 2-into-1 Filter with no box
Right now Im running out of ideas. ANY help is greatly appreciated!
