Anyway, I was told by a GM service manager awhile back that you should ONLY run Shell, Chevron, or Quik Trip (one of the least expensive in our area) gas in your vehicles.
This is probably out of left field ,but this thread has me wondering -maybe it would be a good idea to set up a water injection
system for my 14 .You older mechanic -type guys might remember . Just a small water tank with a hose going to a tiny orifice
placed somewhere in an engine vacuum line . An adjustment can be placed on the hose to control water volume.
This may sound like backyard hocus pocus , but it works well for carbon removal from the combustion chamber. Small amount of water is harmless ,but shines the top of the piston like new. Of course , you have to fill the tank occasionally.
Even seen the more adventurous techs pour a small stream of water directly into the carb throat- - quick clean!
That is wrong and stupid and says little for anyone who believes.Fact is that gas is a commodity that is shared among stations and companies. I have personally witness gas tankers make a delivery to the local Chevron station, then drive down the road to the $.20 a gallon cheaper generic station. In my area most of the gas comes via pipe line and is made by Tosco, BP or Chevron. Go to a Chevron station and you'll get Tosco, BP or Chevron gas. Go to a Shell station and you'll get Tosco, BP or Chevron. Go to Abdullahs Discount Gas, you'll get Tosco, BP or Chevron. Catch a trend here?
As for the carbon, I bet there is a a clogged cat in the exhaust. Rich running will clog a cat. A clogged cat will cause richness. Almost sounds like chicken or egg. With the flies out and different fuel map, I am curious to hear if the dealer will honor the warranty.

Doh!!! I haven't yet checked the air cleaner. .......Dean

We used to do that in the "old days" when you could get to the intake and just hold the rpms up while misting or pouring water right in to the carbs or early throttle bodies. This worked really well on soft powdery carbon fouling. This stuff I'm seeing in my C14 has to be chipped or scraped off. I'm not sure it could be removed with the water injection method.

To the collective minds that reside here. ( I could not find this in a search).
The background first, please.
Just got home from a 3400 mile trip out west to Colorado. Bike ran great. Straight home on the slab in 100 degree temps and cruising at 80-90. Washed the beast and parked her. Next day, well:(
2008 C14 26,000 miles. Flies out. PC3. Premium gas from multiple locations. Regular oil changes. Ridden hard enough that I should not be being told what I am hearing.
Started the bike up next day and it made a noise (hiccup?) and quit. Tried to restart and nothing but crank. The electronic dash then acted up (zeroed both trip meters, lost the whole TPS screen (as in gone), imobilizer flashing fast). Cranked but no starting. OK, figured battery. 3 years old. Voltage drop when cranking (12.5 to 11.0 then 11.4). Ordered and received a Shorai and installed. Now it cranks for a while then starts. And sounds like a can of rocks being shaken. Whoa!.
To shorten this, I took it to a dealer (where I bought it and they know me). They now have the head off of it and are telling me that the combustion chambers are so carbon fouled that the pistons are hitting the fouling ( hence the banging, rattling noises) and that some of it may have broken off and gotten lodged under one of the exhaust valves and damaged it.
Now I've been around internal combustion engines since I was 12 years old and understand that carbon fouling can be a problem in many instances but..... a modern 4 stroke fuel injected engine used the way we use them??
Within 26,000 miles??
WTF??
Any ideas, no matter how radical, will sound sensible right about now.
Thanks, in advance, to the collective minds here for any input you might have.

Are you using Amsoil "scamsoil" by chance?
What were the results of the initial valve adjustment. .....
26k miles, PC3, flys out, I have to ask a few other questions...
did you ever do the valve adjust?
curious as to what dealer will say about that, combined with not checking the air filter in 26k miles also...yeah, i think that could cause quite a carbon problem.
Ugh... not to hijack this thread into an oil thread, but what's wrong with Amsoil?
I've been on this forum for three years now and I've never seen anyone report on a 08-09 reporting that kind of mileage except under very rare conditions. 38 is pretty normal from what I've seen people post for those year bikes.
