It wouldn't lock up the rear wheel if the engine 'just stopped' unless you were in a very low gear. The momentum of the bike will easily keep the engine turning over. It would be no different from closing the throttle when travelling along, unless of course the engine had seized or locked up which isn't what we are dealing with here.

I had this happen to me during my first time touring on the 900 GT with only a couple of hundred miles on it. It came to a stop at the side of the road and would only restart with the clutch engaged. Every time I released the clutch the engine cut out. After phoning the dealer ( who was not able to help other than suggesting the clutch switch or side stand switch may be faulty I removed the seat and wiggled some of the wires around. The bike then restarted ok (but with the engine check light on) and ran perfectly for a number of miles until I got to my overnight destination. On arrival I removed the seat again and experimented by wiggling the large connector near the battery and discovered that the engine would cut out as I did it. I have now applied electrical grease (dielectric grease) to the terminals in that connector block and the problem has never reoccurred in the last couple of years.

Many thanks to everyone who responded/contributed - just as a follow up, the OBD convertor cable arrived and I connected it to my car OBD reader. I was able to read and erase the code and thankfully the EML is no longer lit (happy days). I have cleaned the terminals on the large black relay and coated them with dielectric grease and all now seems to be 100%, Hopefully this now means I have avoided a trip to the Dealers!

Yes strangely the mechanic I spoke to at the dealers asked me the same question - I checked and they were fine as I suspected they would be. The starter was spinning over quite healthily and all the rest of the electrics worked ok but it just wouldn't keep running, so for that reason alone I didn't expect any issues with the battery connections. As skipperT above mentioned it was the large black relay that I unplugged and replugged (although I didnt know at the time what this relay did) which seemed to cure the problem. Now that I have returned home I am going to have a close look at the connections to this relay and clean them with contact cleaner and put some electrical grease on them, which I hope will prevent a reoccurrence of the problem.

What colours are you offered in the States?

Thanks, that is good news. It looks the same as the one I have ordered. 4Pin to OBD2 OBDII Diagnostic Cable Adapter Fault Code Reader fit for Yamaha New (4 Pin to OBD2 OBDII Diagnostic Cable Adapter fit for Yamaha. Item... Once it arrives and I get to try it I will post my results.

I hope I don't offend anyone here that has already purchased a new Tracer 9 GT, but I must say I was very disappointed at the 3 new colours that are offered. I had though I might trade mine in - a 2019 900 GT Model in Phantom Blue - but when I saw the new colours I decided not to do the deal as I loved the colour of mine. I had always wanted the Phantom Blue the first time I saw it and set out to find one in that colour. I do accept that colours are very subjective but I don't think I would ever warm to the Kamo Teck colour.

Thanks for that. I have ordered a OBDII convertor however after purchasing it I read somewhere that it does not work on Tracer Gt's after 2015. It remains to be seen though.

This is my first post so hopefully I am posting this in the correct place etc. I have a 2019 Tracer GT which I bought from new last November 2019. I have only covered approx 3000 miles on it due to the recent lockdowns. Last week when touring in the Scottish Highlands the engine cut out and I coasted to a stop. The engine would restart while the clutch was disengaged and in Neutral but would stop as soon as as I selected a gear or let the clutch out. It would appear that the problem was with the lock-out mechanism which prevents the bike starting when it is in gear. I removed the seat and wiggled some of the connectors under there and it started as normal. Obviously there was a bad connection somewhere. When I got to my destination I again removed the seat with the engine idling and when I wiggled some of the wires the engine cut out. The problem is I am unsure which connector/loom was to blame. I separated the large multi pin connector that is held in place with a rubber type clip near the battery and plugged it back in again. This seemed to cure the problem, but I still am not confident that it won't let me down again. I was wondering if anyone else has had a similar issue and how they have resolved it. There were no Yamaha Dealers for miles around so I phoned the dealer in England where I purchased the bike and spoke to the mechanic who seemed to think the side stand switch was to blame. However this did not seem to be the case as the engine only stopped when I let out the clutch or put it in gear. If it was the side stand switch I would have thought that the engine would still run while the bike is in Neutral. Unfortunately the MIL light is also now on which I think was caused by me running the bike in gear, on the main stand. when I finally got it to go. Any suggestions would be appreciated.
