Hi all
1. Fuel tank rubber belt and motor died.
2. Replaced them and all filters. New injector filters and o rings
3. Checked bike shim timing. All great
4. Replaced all fuel hoses. Breather hoses etc
5. Clean healthy new petrol. 95 octane
6. Bike going great. Tried unsuccesfully a couple of weeks ago to balance the throttles with clear tube DIY manifold. Couldn't get it to work. Lost interest.
7. Took it to the local only bike shop to get them to balance the throttles.
8. Get a call from him
9. Bike balanced fine. Then had lunch and it wouldn't start. Put the fuel settings back to where the were but bike now won't start...
10. I went over thinking it could simply be the undertank fuel pump connector. It wasn't...
12. Fuel pump works. Pumps petrol through the filter in tank after the filter. Fuel return at injector rail pumps fuel.
13. Spark plugs fire. Tested with repair shop tester.
14. Fuel injectors pulse. Tested with shop tester.
15 Battery charged. All Fuses ok.
16. Checked fuel injection box for secure connection.
17. Checked speedo wiring loom to find two broken pins. Ascertained they are for choke and illumination - so assume insignificant...
18. When i asked about the re-setting of the balance of the throttles the shop owner said he "thought he had mucked up the settings as it wouldn't start. I screwed the four adjustment screws all the way in and then out 1 1/2 turns on all them".
19. His gun mechanic is away until tomorrow. I am also 2,200 kms from BMW in Perth and 1,900 kms from BMW in the other direction...
We have double checked everything and I am thinking it is the fuel balance settings.
Any ideas?
Thanks
