I posted about the idling issue in the Technical forum but since I posted i have noticed the headlight issue and am hoping the title might attract the attention of someone who has had the same issues before i pull my hair out!!
The bike:
2007 1098s with 12000 miles, just had belts, oil and filter, plugs etc. full termi exhaust system with ECU and filter
The symptoms:
Bike will start as normal and idle Ok for a minute or 2 and then will stall, it is then hard started for a few seconds before starting again when given throttle, it can run fine again for a minute and repeat this again. It also seems to always stall at lights or when coming to a stop in neutral unless revved.
At the same time I have noticed the headlight (only the headlight, parking lights, dash lights, rear light etc. stay on) will switch off for a second before coming back on, it usually goes off when revving the bike from idle, I have had a multimeter on the battery when this happens and voltage appears stable, around 14.1 volts
What I have done:
Measured the voltage which seems fine, 14.1 v at idle and no more than 14.6 v when revved which would suggest the RR is fine and charging system is healthy, battery never fails to crank the engine but I swapped it for another known good one to be sure, didn't make any difference
I cleaned all connectors around RR and checked for corrosion and sprayed WD40 contact cleaner on all connections behind headlight and under tank, all connections so far looked fine. Jiggled all connections to headlight and relay for loose connections - nothing!
So I am at a loss, next stop is bring it to a dealer but nearest one is over 2 hours away and i need the bike this weekend, any suggestions and i would be grateful?
