749r running rough and dying - can you work it out
 

OK, my 749 was being a bitch this morning. I've cured it now, but, can you work out what was wrong.

Yesterday I had the side fairings off, fixed the contact on the left fairing panel for the alarm. Played around with the neutral switch connector on the back of the engine as it was loose. Had the tank and seat unit off. Set my mirrors up. Set my rear sets up. Fitted an ally pressure plate. All body work back on and basically gave the bike a good all over clean and polish ... no water used.

This morning I start the bike, ride it up the drive and leave it out front ... all OK. Turn the engine off and go to fetch my jacket and lid. Start the bike up and it ticks over nicely.

Get on the bike, flick the stand up, blip the engine and it dies :mad: now will not start for anything.

Get off, leave it for 2 mins and it starts first touch. Get back on, flick the stand up, blip the throttle and the bike just dies :mad:

Get off, leave it 2 mins and it starts. Get back on and hold the throttle at 3,000rpm, pull the clutch in and it dies :mad: :mad:

This carries on for about another 3 or 4 attempts, various combinations of clutch in, stand up, in gear and out of gear. No matter what I do the bike will start and tick over OK, but, dies as soon as I want to pull away.

Can you guess what it was :confused:

neutral switch...............something you did with the connector.........

Partial fuel blockage, or blocked tank breather?

I thought that, but, No.

Very close :D

neutral light wire /connector !

or fogot to wire fuel pump back up!

Nope, bike would start and tick over.

Here's a hint.

Bike would start up and tick over fine when I stood at the side of it. I then get on and stand it upright ready to pull off and it dies.

connector block under seat unit?

does sond like a dicky side stand switch

Turns out that when I'd put the tank and seat back on I had got the fuel pump connector block on top of one of the fuel lines.

It pinched the fuel line, but, on the side stand it allowed enough fuel through to start and run. Sit on the bike and it just pinched the fuel line another couple of mm and starved the engine of fuel.

There was just enough fuel in the line to stand the bike up, blip the throttle and flick the stand up :mad:

Made me think I'd done something to the neutral switch or alarm or similar.

Pig to spot, but, 5 mins to put right and no money needed :D

Nice one!
 

there you go boy!
