K1200S intermittent starting problem
I came back to biking in July after 25 Years and purchased a used K1200S and love the bike
Problems started about 2 weeks after purchase (1st week I rode it quite a lot and then went on holiday) On return of my weeks holiday it would not start. All seemed to be OK with pre-checks, it cranks but does not fire.
It was like this for 2 weeks until I had a local motorcycle repair shop collect the bike and took it back to their workshop
After a week he reported all was OK, they had cleaned up switch gear and interlocks. I did not think this was the reason for the fault as it was cranking but at least it was working.
All OK for a couple of weeks, did not use bike for a week and the problem came back.
Got motorcycle repair shop to collect again, they tried changing the tank with another K1200S they had in stock as thought it may be fuel pump, it still did not start but when they put my tank put on other bike it started that bike fine, so not fuel pump problem. IT was thought that the problem only arises when the bike has not been started for a few days
Still would not start so they took it to BMW motorRad, for one reason or another I had to wait 6 weeks for this, buy the time it went in, the fault had disappeared and was starting. BMW could not find the reason as they could not get it to go wrong including leaving it a few days before trying to start. Nothing showed up on the diagnostics. They recommended changing the battery which was done and got it back to me confident I would not have any further problems.
I have ridden it a couple of times a week for the last 6 weeks with no issues.
Last weekend I went for a ride in the rain and then washed the bike the day after. Straight after the wash I tried to start and same symptoms as before. Makes you think of a water in the electrics problem but this is the first time the bike had been washed since I purchased it and had not been ridden in the rain except for the the last ride. I have had the battery on trickle charge and still will not start.
Not a techie at all and do not have much tools. Just asking is there anything I can easily check before spending more money. I am hoping to take it to BMW Motorad soon as I can as I would like them to see it with the fault showing.
Any recommendations/advice will be gratefully received.
