Fails to restart when hot

[wfooshee]

Well, I stand corrected. That's twice this month. ****.

At least on the cold bike, the pump ran every time I hit the key when I went out and tried it just now.

Takes a big man to accept the public humiliation of admitting a mistake, and I'm definitely a big man.

As for throttle while cranking: No throttle at all while cranking, unless you know it's flooded, at which time you apply wide open throttle while cranking.

And Mike's description of hot starting fits very closely to what I experienced with my starter two years ago.

Has it really been two years!!!

Damn, time flies when your getting old!

 

[wfooshee]

What the hell are you doing still up? It's Wednesday there already!

And yeah, I was surprised to see the time gap. 2 years this very month!

Just a further thought, do these bikes (MkI or MkII) suffer from fuel starvation/evaporation symptoms when they are hot? I'm assuming not as they are injected; but certainly old MG's do

Yeahbut, old MGs used tin cans for carburetors. That tin would get REAL hot and boil away the fuel inside the can. British Leyland products were not exactly known for temperature management under the bonnet.

You are certainly right there; even in a damp cold country like this. But they are a lot easier to fix, mostly a big hammer does the job quite nicely

Yeah, well with your oil consumption and now this news it is clear you have yourself one POS FJR. :lol:

Don't know what to tell you. I have had 3 2004 FJRs and ALWAYS here the fuel pump prime when the ignition is switched on. I would be freaked if I didn't hear that comforting, how did RH put it? "ku-klungggggggwooosssshhhhhhhbubblebubblebubble."

Ok you might be right on this one, I could not duplicate my previous thought that the pump did not always prime. We shall see now that I am paying more attention to it! The damn oil consuming bitch!

Thanks for all the advice; now it's back to the garage to dismantle a bit more (looking a bit like a Yamaha Mecarno kit in there).

I still have no idea what the problem is, but it seems that it isn't a common one which points the finger at a defective part; the interesting question is just which one?????

It seems like the biggest problem might be the improper starting technique, where you mentioned always giving the throttle a twist while cranking over the engine. I would start there and see if the problem reappears.

My scoot does the same thing. I really think it's the battery. My first battery that came with the bike lasted about 4 years and then started going down hill. Replaced it and it only took two years for it to start weakening on me. Me thinks me got a bad battery from stock...where ever I bought it. A couple of mornings ago I had to jump start it to get to work on time. Time for a new battery. :glare:

Check the fuel pump relays. Had the same thing happen on my Ducati and new relays fixed the problem. You should always hear the fuel pump run when you first turn on the ignition (unless the kill switch is on).

Always other variables....go figure.
