Update #2

Well, my impatience and curiosity got the better of me and after checking the wiring diagram I felt confident to proceed without damaging anything.

-I jumped the wires on the connector and turned on the ignition - pump came on, I could hear and feel it
-I then re connected the relay and cranked the bike over , it fired right up - I could again feel and hear the pump working


Just have to do a flow test now, I think it looks easier to pull the hose off the pump and add a new hose there for the testing.

I did "feel" the pump rate speed up and slow down when I turned the fuel pet valve off/on, so its definitely responding properly to fuel pressure. it slows right down to a plulse every second or two at idle and speeds up as the bike uses more fuel or if I turn the fuel valve off.

So seems the relay is fine, despite the manual assuming otherwise

 

Update #3

Fuel flow is GREAT, way beyond the specified minimum

Im gonna call this one Done, my fuel delivery system is good.

 

The next thing I would do is see if you can induce the condition and try this instead of containing to get to start, pen the drain screw on the fuel bowls. Fuel should flow freely from each of them. If this has a positive result, you've confirmed your issue likely isn't fuel delivery related. If little or no fuel comes out, the next thing to do is figure out what is causing this after the bike is at operating temps.

 

Cheers, I cant get it to do the long crank symptom anymore, it starts like a dream even after a week or two sitting. My suspicion is, because it was a year since I last started it (when I had the long cranking issue), I had stale fuel in the carbs (even though it was ethanol free and had stabilizer in it), and it took time to cycle some decent fuel into it.

As far as any other issues, ill have to wait until I get her out for a road test and see how she goes then

Here's the Vid I just did on testing the pump etc. Thanks for all the replies guys, I appreciate the help.

 

is it possible that the points on the fuel pump can stick from time to time causing intermittent pump failure to function?

after I tested the pump (fine). I put the fuel line back on and re jumped the connector and got nothing. I ram the bike for a minute and then hear the pump . Seems like the pump should have had low pressure if the fuel line was off (?). I’m gonna test it again today.

 

The points can stick from time to time but it’s a sign they are becoming to fail. There a guy on here, @IDoDirt in his signature block there is a link to a how to on rebuilding the pump. It’s pretty informative. Its worth a read.

Jumpering the black/blue black wires works until sufficient pressure in has been reached.

 

I think he has link to upgrading pump contact points to solid state version that doesn't burn and stick. Kinda like upgrading from points ignition to electronic.

 

cheers. So far it’s working fine. Starting and running well. I’ve tested the pump a few times and it reacts properly to high and low pressure while running

thanks for the help
