How many miles are on your fz10?

is your ecu flashed? i had the same problem awhile back, ecu flash fixed it for me. i think its a decel cut issue on the bike stock, just a guess. is this going to be your bikes first valve adjustment? im at 30k now and had valves done at 26k.

im almost positive your dealership cant do it as its a warranty issue. i had 2 wheel dynoworks do my ecu flash, sent it in to them via ups and got it back about 5 days later. you can do overnights if you want i just didnt feel like paying for the shipping on my end. I asked my dealership about the bike dying upon stopping when i had that issue and they thought it was my clutch and or clutch plates, still havent had that done yet, i will eventually but the issue is gone thanks to the ecu flash, which leads me to believe it was not the transmission in anyway or the valves. it was the decel cut killing the bike.

FYI if anyone's interested, valve adjustment revealed no clearance on exhaust side at all... After fixing, bike runs like new. Definitely recommend doing the valve adjustment on time or earlier if you start having unexplained stalling. And this is not FZ-10 specific, same issue is prevalent on other Yamaha forums, and my 2011 FZ6R had started having the same issue at ~26k before I traded it in for this bike.
