Bike Stalling Out

[Kabish]

So this has happen to me two times recently and its a bit unnerving... I know there have been a few post about this issue, but I've not been able to go through them all to see if there is a possible solution. I'll be taking my bike in next week for the 12,000 service so I was hoping to gather some info before hand.

Twice in the past week or so my bike has died when merging onto the freeway from an on ramp. I'm coming off the Coronado bridge here in San Diego and merging on to the 5 South, its a bit of a blind curve and the traffic is known to be backed up frequently. Friday I was coming around the on ramp and had pulled in my clutch to down shift, traffic was surprisingly light so I decited to keep the bike in the gear I had it in. During the time I had the clutch pulled in and making the decision to stay in gear the bike died. I was going a good 45mph so I just let out the clutch and of course the bike fired back up. This happend about a week prior in the exact same spot, except that time I did down shift and had to break to about 20mph when I noticed the bike full out died. This time however traffic was stopping so I had to push the starter.

As mentioned, the bike is due for 12,000 maint, it has had all the maint done on time and at a dealer. Any suggestions on possible solutions that I could pass along to the dealer next week would be appreciated.

Maybe the side stand switch is shorting out momentarily?

Mine did the same a few times before it reached 100 miles.
between the 100 miles and to 5000 miles, no problem what so ever..
But in the last 100 miles it suddenly did it once again. Don't know why, and don't think to much about it at the moment.
But of course, if it get worse I wil contact the Yamaha dealer.

(so now at 5100 miles)

There is no 12 k service. That's an oil change interval. You need to check and see that your throttle bodies are sync'd. Some bikes are set so lean from the factory that the paint marked screw needs to be adjusted out more before balancing the other throttle body to it.

Agreed. Refer to these threads for a start:

Sometimes backed flow oil mist gets into these air screw passages and you see the air screw barbs being greasy black. A squirt of TB cleaner to remove the grime and the sync the TB, with the reference screw turn out between 1/2 to 3/4 turns.

My 15 did the same thing at 10,000 sync the TB's and all is well .

Thanks guys, for some reason I thought the last time I was in for service the dealer told me the 12k service was the synch. I just remember him saying that at 12,000 the service was going to be a lot more expensive because it is the first "Service" to the bike. Guess I'll try and find my manual and see what the service intervals are as I honestly don't remember off the top of my head.

I did read those two forum posts before hand, but to be honest its all a tad over my head. I'm an IT guy, can do computers all day long, but when it gets to messing with my bike.. well I just don't trust myself given I only got 2 wheels I know I could do it if I had a little guidance. I worked on my girlfriends car once (now my wife). Her alternator went bad, so I went to be the hero and found it in the engine bay and went to work on getting it out. Took it to Auto Zone and asked them if they could test it, guy gave me a really weird look and said they couldn't test those. I was like WTF ya you can, "sir water pumps either work or they don't"................ Guy said that part was one of the hardest parts to get out of the car, and since I had it out I might as well put in a new one along with the alternator lol

Lost my man card that day

Are you blipping the throttle vigorously when between gears with the clutch pulled in? She doesn't seem the like that much I've noticed. More reserved blipping seems OK though.

 

[Kabish]

I used to blip a long time ago till I had it die on me lol Someone on this forum explained to me on why that is common to happen, so I just stopped doing it. So the bike has not been down shift blip for maybe 2yrs.

The times its died are just straight up pulling in the clutch anticipating having to down shift to a lower speed and it shutting off. It really is an uneasy feeling, that particular part of the freeway has traffic merging from 2 lanes to one, then another cross traffic merge including people full out driving down the emergency lane. Its a fairly dangerous merge area and having the bike doing stupid stuff there is no good ::26::

As others mentioned, this bike is sensitive to having the throttle bodies synced.

 

[mebgardner]

Since the OP is not performing a throttle blip during the anomaly, and since it occurs on a clutch pull: There's a switch in the clutch housing, and you should test it with a VOM.

I understand we're not talking about cruise control anomaly here, the OP did not discuss CC at all. What I am saying is, there's a switch in the clutch handle. Since the anomaly shows up during clutch handle pull, test the switch. That's all I'm saying.

Both my Tenere's stalled until I set up the CO. Way up. +45

I noticed she doesn't like her throttle pulled back to fast as well, it sort of a wast of gas.
you can almost sense it as it pulls ahead and no faster than if you rolled it easy..
Judging by gas millage when you get aggressively to highway speed, it's a touchy system.

I still blip, but just enough for smooth downshifting. I'm quick to re-engage the clutch though as there's not much point in doing the blip if you're not taking advantage of the rev-matching. I don't blip repeatedly with the clutch disengaged or in neutral which is pretty much pointless.
