Actually just the opposite, I was blown away that it was only $100.00. What that small amount leads me to believe is that after a brief diagnostic run through they gave up. I would have thought the cost would have been much closer to $300.00 or more. Had a real young tech working on it, not to take anything away from him or his skill, but the only thing they told me was I needed a new screwnut for the batwing.

Is there a way you can pull all the fuses, except the ones necessary to run the bike, and run it down the road for your test ride? Try to isolate which circuit is doing it by elimination. If it does it only after you reintroduce your sound system, then you know where to start chasing sparks. If it does it when you only have the systems necessary to run the bike, then you have narrowed your search greatly. A multi meter with an amp meter can be your best friend. Just my $.02.

I had ignition fuse problem and it turned out to be in the right handlebar switch wires. I have to park my bike in front of my car so I have to do full left lock to park and back out of my space which pulls on those wires. You mentioned left hand turns, is that when you notice it ? You need to make sure those wires are not pinched inside the housing and that they are in the grove on the handlebar. While running try pulling on these wires. Another trick is to take a rubber hammer and tap on different areas. A good tech can show you the wires on the diagram that would blow the ignition fuse. Most of them I believe are in the handlebars or the iginiton switch.

A while back a lot of people were having issues with the wiring to the top end of the engine (injectors etc) because at the factory they weren't giving enough slack where they zip tied to the frame. When I had the top end of my '03 apart I noticed that the zip ties were so tight they almost crimped some of the wiring. Something to check anyway.

Interesting approach. I am going through the whole bike and checking for bare wires. Will also be checking grounds.

I may be missing something, but the only fuse that ever blows is the ignition fuse. Not quite sure how radio or lights would play into it. Not that it couldn't happen that way. Just trying to get a handle on where to start. Thanks.

At first this is where I looked. Had been in the rt side to lube throttle cables and replace frt brake light switch. Did find some pinched wires but got that a squared away. Talk about 5 lbs of crap in a 3 lb box!

Lke I mentioned before, I just keep getting the feeling something is overheating then overamping. Let it cool off and it is good again.

When I first started reading your OP temperature seemed like the obvious variable that was giving you the short duration of run time....

Lets assume for now that he bike shop is being straight and did the 50 miles on the dyno - with no problem. This, coupled with your later answer that it happens on the road, leads me to consider it could also be a vibration issue. This also fits the symptoms. Possibly a loose earth screw or a plug which has worked slightly loose and is arcing internally.

You may not have managed to notice a pattern yet, but I wonder if it is when you are hitting a bump. Maybe if you had a section of road with speed humps or potholes ideally you could go over these with the bike still relatively cold.

Problem is, still a pig to find

Yes, you are right. No idea what I was thinking on that one.
