[Mad Dog Bianchi]

My 750 SS is probably fighting mad after hearing a new girl will be sharing the garage with her soon. So, on the way to work yesterday morning she stalled in slow traffic, stalled on the freeway at night at aboutr 120 kmh, and stalled later on while on a slight incline to a bridge. Each time the one cylinder went out and then the engine just stopped about 15 seconds later. First time I just sat for about 30 seconds and it kicked over right away, the other two times I gave it a little more time and it fired right up. Weather was about 15 deg. C. Thought it could be the battery (cold weather blues) but it kicked over each time. Sounds like gas starvation. Thinking of looking into water in the tank, clogged fuel filter (??) and anything else you lads may suggest. She is really ****ed off!

Carb icing ?

[Mad Dog Bianchi]

I thought so at first but then I saw the temp. Not that cold really. I usually have that problem in Feb and March when the temps really drop here. Maybe more moisture in the tank iced in the carbs. Will check it out this weekend.

did you check for a clogged or compressed fuel line? or a clogged or compressed vent hose?

[Mad Dog Bianchi]

Wow1 I never thought of the vent hose. I had a tank bag on and that may have been the culprit. Simple things like that get overlooked too easily. like the time the distributor cap on my '64 Chevy cracked and I was sure the timing belt had jumped. Spent all of Thanksgiving in University parking lot working on that. Coooold night!
So, your post is really appreciated! Hope you are right!

If it happens again and your bike stalls/stops. quickly open the fuel cap. If there is a venting/pressure problem, you'll hear a "pop" when you open the cap, as the ambient air pressure equalizes with the pressure in the tank.

It can get so bad that the pressure can implode the tank!

-2c The other night going home from work, never missed a beat!

Think she might just be upset

Might be the case. I filled the tank up the day before and there was a pop as the pressure equalized. Seemed funny at the time, especially in light of the cool weather. Will check the vent tube. But, as Stu said, I think she is just upset and I feel this will get worse as she gets relegated to second fiddle!! What should I do to keep her happy?

Don't let happen to you what happened to me :-)

I woke up one morning to find my tank had imploded. I had no idea what could have possibly caused it. Eventual concensus was a clogged vent hose.

I hope you get it sorted soon though. Good luck.

I'll add that to my weekend check!
