I just happen to have an 1100 V-Star that I will be selling. I do not know which model it is. I was told when I bought it that the motor he just put in it was out of a wreck and had about 1500 miles on it. I have put less than 100 on it since I got it. It is dressed with bags and a trunk that I put on it. All black. Tim B. just rebuilt the carbs for me. (see below...this is why I sent them to Tim....to make sure it was not the carbs)

I will tell you....I am selling it because I am at my witts end trying to get it to stop fouling plugs. I have done everything I know, and most of what the guys on here have suggested, and it still fouls both plugs in about 2-3 miles or so. Pull them and clean them.....fires right up and start all over. 

If you are more savy than I am, and can figure out the (I'm sure) simple thing that is causing this, it will be a good bike. I will take $1500.00.

Hi,

Blocked crankcase vent (this would be common to both cylinders), bad oil rings.

Rings?  You never know who was in there before you and botched things up.

Don't know if these will give any insight or not, but......plug pics and a short video of the exhaust

Have you done a compression test?

As Mick said and also have you checked timing? I have read some of your past posts but don’t remember if this was covered. 

Did you find a bike? Think I’ll sell mine. 2200 miles and nice. A Classic Silverado. Carbs rebuilt and synced last year runs and looks really good. 

I have a short list of last ditch things to check when I get back to Birmingham. Bike is about 5 hrs away, so I only get a little while to look into it when we go through there. Hopefully, I can get it down here in a couple of months and be able to spend a little time to give some numbers in here and see what comes up next.

Thanks to you and Mick for the input

2200 miles? where are you located?
