Maintenance and Servicing / Re: TC, ABS and engine stalling during random downshifting« Last post by MotoJB on Yesterday at 11:23 pm »Will be interesting to see if we can find a consistent pattern in the information about other bikes that have had the problem.
Good work Joe.  2

We are beginning to build a useful information base that could determine the cause of this abnormal behaviour. I suppose your 2022 bike has been updated with the most recent software version at its annual service. I hope other members how have experienced the problem will provide similar reports. Please keep us posted.  Mine has not had any of the software updates, as I have performed all maintenance myself so far. 3

Although, I have always found that with a forward lean, the weight of my head and the weight of the helmet causes a sharp pain in the middle of the spine after an hour or so. That was one reason I chose the TS660: for its more upright riding position.I use the same type of ear protectors but the noise is still too loud for my comfort. The Bell Star helmet might not be the quietest but I'm sure the noise is a lot less when riding the naked Yamaha. I'm going to test the noise issue with the TS screen removed completely.  5

Remove the coolant reservoir, then unfasten the bracket which holds the MAP sensor, held on by a torx bolt. I was able to get the tube off of the exhaust manifold by gently pulling straight down in line with the nipple. Reinstallation was a struggle. Warming up the tube to soften the rubber helped. Those with bigger hands might need to do some more disassembly. Originally Posted by MotoJB That's really interesting and good evidence to help explain the problem. Please let us know how you find the engine runs on the road and if and when it stalls again in the manner we've been seeing. How old is your bike and how many miles on the odometer? What fuel have you been using? Mine is a 2022 purchased in July of 2022 with just over 9000 miles on the odometer. I use regular 87 octane unleaded (E10). I've filled up with ethanol free a couple times but did not notice any change in character. I will see how she behaves and report here if I notice any other changes. 6

Maintenance and Servicing / Re: TC, ABS and engine stalling during random downshifting« Last post by joebwebb on Yesterday at 09:22 pm »Today I finally had the time to pull the MAP sensor tube. I found that it did have a good amount of dark oil in it, conceivably enough to collect in the lower bend of the tube and interfere or block air flow to the sensor. I cleared the oil out by blowing air through it and then running some brake parts cleaner through a few times to remove any oil residue.
I have not ridden it since, but after I put it all back together I noticed that the engine now fires up immediately (cold) when I push the starter switch. Normally it will not start on the first crank but starts ok on the second. 9
Maintenance and Servicing / Re: TC, ABS and engine stalling during random downshifting« Last post by MotoJB on Yesterday at 04:38 pm »I met a person last week who has owned and ridden motorcycles for over 50 years. He is retired from his life's work as a builder of racing cars. He has never owned a Triumph motorcycle but when I described the stalling engine on closing the throttle problem and the potential causes cited in this thread, he immediately responded to the effect of the change in fuel composition from E5 to E10.
There is an ongoing debate about the matter so no firm conclusion as far as I know. I respect this person's experience and opinion. I would like to know if this issue has been thoroughly researched and reported on either in academia or by the industry. What are the conclusions? Meanwhile, I have always used E5 fuel and will continue to do so until proven I can do otherwise. 10
