Don't want to "hijack" the other thread, but having my own weird issue.

2004 Vstar 1100. Had for about 2 years now, NEVER a starting problem.

Today I rode over to get a haircut - about 4 miles. Around 85 degrees out. Bike started right up as usual, rode fine over there.

When I came out and went to start, it made a "clunk" noise. Then cranked fine, but wouldn't start. Tried giving it some choke, no dice. Tried giving it some throttle, no dice. Moved petcock to reserve just in case it had got low, no dice. Cranked fine, but no "fire"...

Turned it of (both kill switch and ignition). Put the stand down and gave it a look over. Nothing seemed amiss: no vacuum caps off, nothing leaking, plug wires secure...

Got back on, tried again, fired up but rough. Wouldn't stay running without choke. Got to end of parking lot, stopped at a stop sign. Died.

Started right up when I tried, less rough. Rode home fine, smoothed out and no more 'dying' at stop signs. About half-way home I backed the choke off and it was fine.

Got home, shut it off, turned it on, started it up and 'bam' like usual, started right up.

Haven't had a chance to really go over it yet... Just wondering if anyone has anything to suggest.

FWIW, my first thought was back kickstand switch... But I don't actually recall if it'll even crank with the stand down and in gear. I just know if you PUT the stand down while it's in gear it'll stop... Easy enough to test that when I get back out to the garage. But gotta finish my work-day first.

sounds like a piece of crud worked it's way through the carbs, change the fuel filter and keep riding, and don't forget to open the reserve once in while to keep the reserve tube clean

It's not a good idea to give throttle on an 1100 when starting. There is no accelerator pump on the carbs...so it does nothing but advance the timing.....which can and will cause kickback...like the clunk you heard. It can also take out the starter clutch (that is what is clunking) and you're looking at about $800 to have a shop repair it.

Now...with that said, you can get a vapor lock after shut down in warmer weather. All that heat from the motor soaks into the carbs and boils the fuel in the bowls. The most common cure is to just hold down the starter button until it fires (count to 25 before letting the starter button go). 9 times out of 10 it will fire. The fuel pump only puts out 3-4 lbs and it just takes a little help to push the vaporized fuel out.

Thanks, Pauli466. No harm in changing the fuel filter regardless, it's about a year old anyhow.

Thanks, Mick. I didn't let it crank nearly that long, so will have to try that if it happens again.
