Mike, my dealer puts in 5 gallons of 99 octane race fuel with each new bike. Why? :dontknow: It what they do. :thumbup: Tom :spyder:
...... My personal blend is SeaFoam and Techron mixed 50/50 and dosed at 1 ounce per gallon.
Carbonation: Interesting Mix 50/50 Why?
The tranny shuddering at low RPM feels bloody awful but is quite common on these early machines, especially with a cold engine, and yet it isn't usually damaging in any way. It usually goes away as the bike/oil warms up... So that might not be as bad an issue as you might think.... once all the other stuff is sorted. :lecturef_smilie:
The vacuum hoses are a known problem and they can look perfect until you take them off & kink them double, when it becomes obvious that they've been Wallaby Ted's older brother Roo for a loooong time, leaking air like a sieve, and will probably have been causing all sorts of erratic idle issues for all that time too!Replace all three of them with silicone hoses & be done with it, & while you're at it in there, check & replace the throttle body boots at the same time! Save yourself from having to go back in later - you'll work out why this is important once you start replacing the vacuum hoses etc! And while it's all naked with the tupperware removed, check, clean, &/or replace everything/anything else that looks the slightest bit dodgy that you can get at too - MAF, air filter, fuel filter, purge valve, etc, etc - do anything & everything you can! :thumbup:
Additive type injector cleaners - they rarely work wonderfully once the offending injector is already gummed up - arguably, they'll work best if used from new as a preventative, and those that are successful at 'after the fact' cleaning generally take a looong time and quite a few tanks full of fuel with the appropriate level of additive mixed in to do anything, anything at all.... so if you want if fixed NOW, don't waste any more of your time &/or money on adding questionable additives anywhere in a likely futile attempt to clean them that way, just get the injector's out & have them ultrasonically cleaned.... or maybe replaced! :shocked:
Good Luck! :2thumbs:

It's very possible that the race fuel your dealer is putting in does not have ethanol.
Using fuel without ethanol will allow a dealer to set up a bike / trike and have it all prepped for delivery. Using non ethanol fuel gives them some security that they will not have to worry about the fuel system having an issue until the bike / trike sells.
I do not think it has anything to necessarily to do with the octane. The fuel they can get from a supplier without ethanol may just happen to be race fuel with a higher octane.
2012 RT-L SE5 . 3500 miles. Tranny Shudders at low Rpm s Erratic idle. Engine check light Code P-1171 cyl 1 lean. Had run perfect after purchase 2weeks ago. No mods. Checking vacuum hoses will replace off of MAP sensor. Will check throttle body boots.Possible #1 injector clog. Any way to direct injector cleaner ie seaform etc closer to throttle body/injector besides as an additive to gas tank ?Planning to add Air scoops per 2013 recall heat mgt .
My 2013 RT threw a throttle body code once. When I got back to my dealer he checked it out and then added Yamaha fuel injector cleaner to the gas. Since they used Yamaha branded FI cleaner I figured it must be a decent product to use. I've no idea how it compares to other brands.
I had one incident of the throttle body sticking in the fall of 2014 with a limp home failure and the engine would not drop back to idle. I'm not sure what I did but I got the error to clear up and the engine to drop to idle so I continued my travels. I stopped at a dealer in Eastern Idaho and they checked things out and cleared the code. They said to have it checked by my local dealer after I got back home.All I remember is the additive was Yamaha brand and they added it to the gas. I think they gave me the bottle and I used it in the gas until it was used up. The plan, which apparently worked, was to use the additive to clean the throttle body to prevent the throttle butterfly valve from sticking again. I believe this was the factory suggested fix before resorting to taking everything apart to clean the throttle body. I do remember having doubts about it since the fuel injection point is downstream of the butterfly valve. I didn't ride much more that fall and then sold the RT the next spring after I got my 2014 so have no idea what, if anything, has happened since.Did they use Yamaha Ring Free?
That rabbit hole is deep, but if you dive far enough into MSDS sheets, comments, anecdotal recommendations, and the opinions of a million internet experts, it is basically Sea Foam and Techron mixed together.
Where might you have heard that?
