NoGo on reserve

Excuse the living heck out of me if there's info on theis already, but this has happened to me twice, and I haven't seen any posts on this yet.

Here's what goes on: I switch to reserve and baby acts like she's completely out of gas. I stop and slosh the tank around, and there's fuel in it. I fiddle with the petcock and throttle, hoping to prime it, and no result. Someone stops (usually a Harley rider!), goes and gets gas, we put 1-2 gals. in, I start right up and run down the road!.

I'm planning to take the tank off and have a look at the fuel filter/petcock mechanism this weekend (soon as I can minimize the amount of gas i nthe tank I got free from Fatboy rider yesterday). Maybe I've got filter clogs, or a sticky valve, dunno. Anyone had this one? I've seafoamed redently, but this is the second time for this, and the first was pre seafoam, and over six months ago.

Did you turn the valve so that the long part faces the front of the bike or the rear? If it was the rear, you turned the fuel valve off. Our valves are kind of counter intuitive. Don't feel bad if you did. Someone else here did it too.

I have a 2005 with 10000 miles. This happened to me one time. Now I leave the petcock on reserve at all times. The bottom of the tank is an ideal place for condensation to collect if it's never used.

So that's what I've been doing wrong.. Never had to go to Reserve while moving, but tried it while ideling and it quit instantly with the long part of the
backwards valve pointing back.

If you got the reserve the right way (opposite of trashlord's first time), then it is more than likely crud clogging the petcock filter. But that is a lot of filter to clog.

Also, with the carbs being CVK type (vacuum) you can't really prime them by just twisting the throttle. The engine needs to be turning over.

Checking the petcock would probably be the best place to start.

I went to town on my way to work to fill up. Was getting low and it ran out of gas just as I came into town, switched to reserve and it smoothed back out. It was the first time on this bike for me to go to reserve. It took 2.8 gal so I had plenty left. Went ahead and added my seafoam as it's been about 1000 miles since the last time. Still running fine. I've always wondered what that was going to feel like. I was on a stretch where it goes from 70 to 55 so I was coasting anyway and was able to roll the knob forward and didn't hardly miss a lick.

My KZ has an on/off petcock and I was leaving it off about every other time I rode it so I'm used to rolling the petcock on while moving.

Hizzo, that's a good idea. Think I'll do that while my tank is full of gas/seafoam mix. Thanks buddy!
