Hyosungs and ethanol>>>NO GO

Rubber and Ethanol are a no-go.

That would explain exactly why my car has been running like shit. GREAT. Fuel lines, injectors, corrosion...what a wonderful list.

It says it is ok in Suzuki's, but still I will not be using it in the bike. Bugger that.

Not at the temperatures your bike lives in. Well... not for a long time.

Rubber ain't a proper word dudes, it's generally held to mean "sorta soft an' squishy". "Rubber" components on vehicules might be one of a small number of synthetics, neoprene, nitrile etc. Replace the existing "rubber" with one compatible with the newfangled gas and you won't have a problem.

'Course, you might have to tweak the tuning too...

Its the same story all over again..... Remember a few jears ago when they introduced the new unleaded fuel and caused a few people problems with old cars. I had to re fuel line and do a pump and carb rubber parts overhaul on my old MG Midget. Well the old MG will run fine on 5% Methanol now but was a bit of a pain at the time. I guess I was kind of lucky that I could get the parts in synethetic rubber for the fuel system. I bet that the owners of older jap cars won't be so lucky.

Alcohol is hygroscopic. Tipping a litre of methylated spirits into the gas tank used to be a way of absorbing any water that may have been lurking in a crevice at the bottom, thereby stopping the dreaded pinhole leak happening when it finally rusted out. Years later the same thing now "causes" corrosion in tanks. Interesting. The methylated spirits with the fuel absorbed into it was burnt in the usual way by the engine.

Also those lists of vehicles were made after consulting importers and agents here in NZ. If no definitive documents were available from the manufacturer then most likely whoever they asked would not approve the blended fuel in their vehicles. It's called "butt covering". It doesn't neccessarily mean your vehicle will have a problem with the fuel, just that noone they asked is willing to say it won't.

Fuel lines I've been told may be either petrol(tolulene/toluol) proof or alcohol proof, not both. However in low concentrations methanol will have indiscernable effects on normal flexible fuel system components. The unleaded fuel we are now stuck with has high concentrations of toluol which is an industrial solvent and pretty nasty stuff. It was this stuff that dissolved fuel lines and caused all the problems when unleaded was introduced.

I normally run 100 octane in my bucket and my boys KX80. I have some jugs and things I use for mixing the fuel. The other day I mixed a batch of pump gas for the KX and dissolved one mixing container in about 5 seconds.

Yeah did that ages ago, found all i have to do now is adjust idle between caltex vs Gull say.
Engines are awesome at telling you they don't feel good. Exup valve deals with the vapor pretty well to.

lol i could show about a 1000 youtube videos of why too

Still i ran about 10-20% cut into the RG back when i had balls and the oil pump failed way before the fuel lines.

Bugger So Kawasakis cant use it then.

I see Mobil in Johnsonville finally has some decent stickers on the pumps and flags on the hoses warning people they are now all an ethanol mix, took them long enough.
