When was the last time you changed your fuel filter?

I had similar issues in past and ended up changing fuel filter and had a loose spark plug.  Good luck

If you didn't get any maintenance records then I'd change the filter ASAP.

Like ab said...he had a plug wire issue.

You should check those connections, both at the coil end and the cap end.

If the connections are good, you could try swapping coils.

First do a compression or (better) leak down test to confirm the engine is good.  Compression good?  Swap the coils from the horizontal cylinder  to the vertical cylinder and see if the vertical cylinder now stops.  Do the same with the ignition wires and spark plug caps.  No difference?  Could be a fuel injector.  Oh, and change the damn fuel filter  [bang] [bang] [bang] it is a maintenance part and should be changed anyway.  Also go for a ride, hit the kill switch and coast to the side of the road.  Remove the spark plugs, take good photos and post.  If there is a good repair shop near you it might be worth it to bring the bike to them.
