I have a new to me 06 with 4500 miles on it that I bought 3 months ago. First thing I did was have all the fluids and filters done as well as a TBS, no spark plugs or valve check. Last week about 5 minutes into my ride I was stopped at a light in neutral and the engine just died. Started it back up no problem and hoped that maybe it was me that killed it. Last night same thing, sitting at a light, either in 1st with the clutch in or in neutral, I don't remember, and the engine just died. This time when I went to fire it back up the bike sort of "paused" or "struggled" to start back up for a moment. Also of interest was the my odometer went from the trip computer to the odometer reading. The trip computer was not reset but I had to scroll back to the trip computer. Other than this issue the bike runs perfect. Rode it to work this morning (20 minute ride, stop and go traffic) and bike did fine. It just so happens that this weekend I plan on pulling the PAIR system and installing the Wynpro plates (which look awesome by the way and only took 3 days to get to me after I ordered them!), doing an unauthorized TBS, and installing new spark plugs. Anyone have some wisdom on what this may be? Plugs, battery, fuel pump? I am somewhat mechanically inclined but talk to me like i'm 5 and that would be helpful. Thanks guys.
). Other brands work to an extent, but this stuffs from Yamaha themselves. And at $26 for a small bottle verses $5 from autozone, it's good &*^%. And next, if your wanting to tackle it, clean your throttle bodies! I can't guarantee this is the issue, but I've seen it more than once. If the t-body becomes dirty, it can get between the blade and the housing restricting the airflow, thus not enough air and the engine will struggle to stay alive and even die, once warmed up of course. When it's cold, it controls its idle on it's own with the IAC valve(vise versa) so it doesn't come into play until it's warmed up. You can do this without removing them, unless you want to. Remove the tank and airbox so you have a straight shot at the t-bodies. Get the engine warmed up somewhat. Then use preferably t-body cleaner(aerosol can), and while regulating the throttle to keep the engine alive, spray it directly into the t-body/intake. Don't be bashful either, use a whole can on one if you have to. And repeat on all of them, reinstall airbox and tank, and see if the problems fixed. This is one if the first places to start if no other signs or symptoms are present. Good luck!
