Riding home from work today and my 2007 Bonnie Black cut out on me. I'm sitting here waiting for the flatbed to tow her into the shop (thank god they are still around).

Now I'm sitting here wondering what happened.

The battery seems fine and she has a full tank, but I've done a couple things recently and think one of them may have something to do with it.

1. I replaced the air filter.
2. Recently replaced the silencers with those off a thruxton.

Any one have any thoughts?

Thanks for the response

I have a full tank of gas. It started up and ran fine for a few miles so I ruled out the side stand kill switch and any battery/spark issues.

I'm stumped.

it turns over but does not start ?
did you check to see if you have spark at the plugs ??
do you have a spark checker ?
if not take an old plug put your plug wire on it, ground it against the head or any part of the bike that is grounded and turn over the bike while looking at the plug for a spark. if there is NO spark it will not run and you need to narrow it down from there. the pick up coil is a common problem just like the crank sensor on a car. on their last legs they just plain quit when warm. let em cool off and they work again. your igniter under the seat could have a bad connection too. 1st check for spark !!

Thanks great suggestion.

Would you say that may fail around 10,000 miles?

the little booger is like rolling dice, you never now. some people on here get 40k outta them, some less. i road tested a caravan got 5 miles from the garage and it quit like i turned the key off. got towed back to the shop and it started right up. crank sensor, just like pick up coil on our bikes. do a search here, there are tests you can do to check em out. some people have put them in a pan of hot water and watcehd them fail. check for spark !! i have one of these; http://www.harborfreight.com/inline-...ker-69014.html very useful tool.

link to pick up coil testing.

I ended up dropping it of at the shop, I was able to bribe him to stay late with a 12 pack of beer.

When I got there the bike had cooled off a bit and it started right up. He said: "do you want to ride it home now?"

Lol.

We kept it running for about 7 minutes and then it cut out again. At least I wasn't crazy.

We can pretty much rule out something with the fuel system and look at electrical issues.

I will let you all know what we find.

Thanks again for the suggestions.

I would suggest checking for good grounding..sounds very similar to a problem I had with my Buell
