When you have a blow fuse, Will the engine crank?

[JeffD]

depends on which fuse.

Ok Here is the situation, fuel take of gas, riding to work this morning.  I was doing be between 55 and 60 mph when the bike just shut down.  It acted like I was running out of gas. I pulled over to the side of the rode, verified that I had plenty of gas,( only 30 miles on a full tank) I tried to start it, no joy.  It will turn over, but just wont start.  I switched it to prime and waited about 5 minutes and tried it again.  Still no luck!  It will crank good, but it just wont start.  I am going to go back and pick it up during my lunch hour.  Any idea???

If you blow the fuse on the starter relay you'll get nothing, no lights, no crank, no nuttin'.  Sounds like you have a fuel delivery problem or spark related problem

I'll grab a set of plugs on the way to get my bike

[luke1645]

you might have a  vaccuum leak too with the fuel lines. check that out too

I had a fuse blow one day and the bike wouldnt turn over, lights etc but would start on bump starting, and would keep trying to die, eventually wouldnt start with bump starting...

check the fuse.

Normally, bump-starting only needs to provide compression, but not spark.

Power from the battery runs through the fuse to get to the ignition switch.  But power from the R/R runs straight to the ignition (not through the fuse).  If you popped the fuse while riding, I suspect that you'd have power for a weak, intermittent spark coming from the R/R, and the bike would struggle.  If it killed, then there'd be no battery power to turn-over the engine.

But trying to bump-start with a blown fuse, you'd need the engine turning over fast enough to produce a fat spark, which sounds much harder than a regular bump-start.

ok, we couldnt get the bike to start with ne plugs. Loaded it up in the truck and took it home.
 We started troubleshooting the fuel flow problem.  After a couple of hours and a few cold ones
Here is what we found:
It looks like the petcock is the culprit.
when we ran a straight line from the tank to the carb,  she starts and runns great.  If we put the old petcock back on, it goes back to having the same problem.

Does anyone know a a resonably priced pet chicken that can be used to replace the OEM one?  The want like $70 for it at the local bike shop, and 55 for it a bike bandit.

It I just run it straight line with a filter, what else do I need to do other that plugging the vaccun line on the left carb?? :dunno:

not to change the subject, but what is bump starting?

[The Buddha]

Push it and get it in gear and drop the clutch... 2nd gear works best.
Cool.

[sanityfree]

why don't you just call it push starting?

Did you try running it on prime? It may be a simple vacuum problem.
