fuel flow problem

I filled up the fuel tank then while finishing up a 150 miles ride yesterday I was on the freeway when the bike bucked once then quit. I recognized the situation as low fuel and switched to reserve while pulling over to the right. Sure enough the bike restarted and I make it home to discover plenty of fuel in the tank. I assume I have a problem with the fuel petcock and the vacuum diaphram system as I have no fuel filter or other restriction. I do intend to check the vacuum line and bypass the petcock diaphram because I need more than a 150 mile range. Since I'm a cheap bastid I want to simply cut out the center of the diaphram, remove the needle plug and spring, cap the vac line and be done with it. Any one have a problem with this? I realize I will now have to turn off the petcock when I park the bike but I think I can train myself to do this. I know others have had this problem, care to share your fix? --Jim A-15

He Jim, Another possible cause is failure of the float valve to shut off, flooding the carburetor and stalling the bike while running. This may have occurred temporarily and then corrected itself while you pulled off to the side and restarted. This problem has happened repeatedly to me, to the point where I am now replacing the float valve. If it occurs while the bike is stopped, fuel will begin to run out the overflow on to the ground so the problem is pretty obvious. The problem can be dealt temporarily, sufficient to "limp" home by shutting the petcock off (to prevent overflow) and on (to fill up the float bowl), thereby manually performing the task of the float and float valve (yes I have done this on several occasions). So before you attack the petcock you may want to see if this problem happens again and consider other possible causes. Good luck, Brent. ________________________________ From: DSN_KLR650@yahoogroups.com [mailto:DSN_KLR650@yahoogroups.com] On Behalf Of Jim Sent: October 2, 2006 11:13 AM To: DSN_KLR650@yahoogroups.com Subject: [DSN_KLR650] Fuel Flow Problem I filled up the fuel tank then while finishing up a 150 miles ride yesterday I was on the freeway when the bike bucked once then quit.

Hello Everyone, Yesterday, on my way home from work, I was cruising along at around 65 mph. All of a sudden the bike boged like it was running out of fuel. I quickly switched to reserve and it returned to normal. The problem is I had filled her up 103 miles prior to the incident!?? I pulled over and did a visual on the fuel level and it was a little better than half full. I checked for leak and found nothing. So know it seems to only run on reserve. Does anyone have experiance with this type of problem? The bikes an 07 with 8500 miles on it. Any help would be greatlt appreciated. Tony

It could be that the filter on top of the 'normal' tube that goes into the tank from the petcock is clogged, while the reserve tube filter isn't (yet). Can you see any crud in the tank? __Arden

<><><><><><><><><> <><><><><><><><><> Tony, On my 2003 I had a similar issue once. I flipped to reserve and the bike ran fine. The next ride I put it on main and it was fine and has been since then. No idea of what happened or why. Maybe try putting it back on main and seeing how yours runs.

Could it be a temporary glitch in the vacuum action in the petcock? Maybe a momentary bind in the action and the next time you start it it works correctly. Just an idea.

Apology to the list. I should have used NKLR in the subject line.

For what it is worth, I experienced the same exact situation as Jeff did, about a year ago, and no problem since.
