Vstar1100 with rear cylinder not firing
Good morning y'all
I haven't been on here for a while. I have a friend's Vstar 1100 custom, I think it is a 2006. Out of nowhere yesterday after a 200 mile ride it began to run on one cylinder. After we got it back to my house I took it for a ride and found on idle and to about 10 MPH both cylinders were firing. after 20 MPH 1 cylinder would drop off. I figured out the rear cylinder seems to be the culprit.
I do not have a timing light so I cannot say with 100% certainty that it is a spark issue, but that seems most likely to me.
I was hoping that someone else may have experienced the same symptom and figured it out. I hate to have her buy a coil and find out that is not the problem. It could be the igniter which would be pretty pricey obviously.
Now I suppose it could be a carb issue, but that does seem less likely to me, especially the way it came on so suddenly.
And suggestions appreciated. Not a mechanic here , just have done allot of basic repairs, but not a professional wrench by any means
Happy 4th of July weekend
