I have not updated my progress on this project in a long time. A computer crash then work schedules have kept me from doing any more work on the bike.
After the tranny and engine overhaul everything worked great. But of course a new issue has came up.
Early this spring it ran good. Things got busy and I have not started the bike for a few months. Yesterday, in the 100 degree heat, I went out to take her for a little ride. It started like always, a little choke and hit the button. Third thump it fired up and ran. I let it sit and run like usual with the choke on half while I put my helmet on, then I dropped the choke. As soon as I shut the choke down it missed and started sputtering, so I gave it a little choke again. It had been idling about 30 seconds by then. The choke usually helps get it evened out until it warms up a bit but this time it died. I could not get it started again. I had good spark, but in the heat I didn't check any more than that, so I decided to leave it until evening.
Last evening when it finally cooled off in the shop I went back out to work on it. It still wouldn't start. I opened the drain screw on the bottom of the float bowls and only a small dribble of gas came out. I pulled the line from the fuel pump and a very small amount of fuel ran out. Maybe a tablespoon. I hit the starter button and it would burp gas every revolution.
I noticed that when I turned the kill switch from stop to run with the key on the pump would click and burp our a little gas.
With the line from the pump to the carbs off I opened the drain screw on the bowl again, allowing air into the line gas ran out of both the hose and the drain. I then pulled the line from the tank to the pump and gas ran out in a good stream.
Put everything back together and tried it and it started right up.
Today in the heat I went back out to go for a ride. I had the same problem as yesterday, it started for a few minutes then ran rough, then killed out. Now it won't start again.
Any ideas?
When it cools off I am going to go through the test proceedure for the pump. Any other ideas?
