After wanting an FJR for years I finally picked one up about 4 weeks ago. It's a 2007 model with 42k miles and has the auto clutch.
All was well for the first two weeks and then out of the blue the bike cut out on me at a junction. I had a few other issues show up on this journey which resulted in the warning light flashing and the ABS light flashing. I later found out this was due to the rear foot brake lever pivot sticking and holding the back brake on. The pivit was cleaned and regreased and all was well.
About a week later the bike cut out on me at a junction again, it did this several times on that journey but would always start straight back up when put into neutral, it would sometimes cut out as soon as 1st gear was enaged though. It also coughed a few times while I was riding at 70mph on the motorway but didn't cut out. I managed to get it home convinced the issues was the side stand switch and sure enough I found if I wiggled the blue connector for the side stand switch (it's behind the fairing on the L/H side of the bike) I could make the bike cut out when it was in gear. I cut this connector off and attached new spade terminals and some heat shrink and the issue seemed to go away, I can pull and twist this connection and the bike stays running.
Cut to today and I took the bike out and all was well for the first 5 miles or so but after it had properly warmed up the bike coughed again while doing around 30mph and whilst pulling upto a stop in traffic the engine cut out. The engine started straight away again but there were several occasions where it was coughing and stutterting at low speed and it did manage to cut out a few more times when coming to a stop but as soon as it is restarted it idles perfectly.
With the bike having an auto clutch i'm not able to pull the clutch in and rev the engine to keep it going when it stutters so this issue for me is fairly dangerous as I just end up stranded in the middle of junctions while I try and get going again.
The bike always starts, the idle speed is rock solid, the bike has had all the recall work completed and has been well looked after.
I'm really rearing my hair out with this. The guy I bought it off did say he'd had issues with the side stand switch which casued the engine to cut while it was being ridden but that this had been sorted by his Yamaha dealer and he'd had no issues since it was fixed.
I plan to bypass the side stand switch altogether and see if the issue persists but if this doesnt work can people suggest what else I could look at? I'm thinking possibly the Throttle Position sensor as I know these can cause intermittent cutting out and the fact that it only seems to happen when the bike is hot could also point to that. I've currently got all the panels off the bike and am going over all the wiring and connectors but so far they all look OK.
Any suggestions are very greatfully received.
