h igh i am a new member i bought a 2010 tw200 from a lady it only had 500km on it i dont know how to post pictures yet i was just woundering what grade of gas is every one using my bike seems to have a rattling noise when cruising at higher speeds or is that normal i have over 2000km on it now and had the valves adjusted and oil changed at 1200km at the dealer it dosnt seem to make a difference what grade of gas i use thanks

The manual says to use regular unleaded. At first I was using premium then switched to mid grade for a bit. But now I just

Use regular unleaded. I have not noticed any difference in performance as to when I first ran the higher grade gas. I haven't experienced the rattling noise on my bike that you mention. What speeds are you going , higher than 100 km/hr ? Also I am

Running with amsoil synthetic in mine.

I strictly run R90 Non-Ethanol fuel, no problems and no noises.

All I can get is regular grade. Never have had any issue with it.

thanks i only travel at 80km per hour i think that is where it starts to red line it did that from the time i first got it maybe im just parienoid

Use regular gas. Higher compression engines need a higher grade gas. Using higher octane will do nothing but cost more money with no advantages to regular unleaded in the TW. If you can find non-ethanol 87 that is the money ticket!

My bike runs fine in the Florida heat with 87 non-ethanol.However if I do have to run ethanol then I switch to 89 octane. No pinging then.

Thanks Guys!



I have been running non-ethanol premium but will switch to the regular and remember to get premium when getting "corny" gas.

"Premium" is in name only - it has pre-ignition inhibitors in it, is meant for high compression engines, has less energy in it than regular gas, and will actually deteriorate performance and gas mileage in a low compression engine like in the TW. It is totally unnecessary for these bikes to use premium fuel, unless you want to go faster from a lighter wallet. "Premium" does not mean it is "better" than regular, only that it's formulated for high compression high performance engines that may knock with regular gas.

Well put. A properly jetted TW will run fine on 87 octane (R+M)/2 method. If it pings, either your carb is not jetted properly, your engine is really hot, or your rpm is too low.

Haha , I like the way you put that. Ive only ran regular gas in mine and always. The only pinging I hear is the extra change rattling in my pocket. lol...

Just thought I would add some additional info on grades of fuel according to Shell's gas here in Canada

Regular grade gas contains 10% ethanol

Mid grade 5% ethanol

Premium grade contains 0% ethanol

If that is true, I'd run the premium grade.

 

[losttourist]

That info I got was from the gas pumps the last time I fueled up. I tried researching Shell and the other companies here in Canada. What I found was only Shell's Premium grade is ethanol free for the moment. Though I did read somewhere that all grades of fuel sold here will at some point contain ethanol.

 

[retmotor]

^ That's the same fuel situation here. I would have to buy premium to get non-ethanol gas.



Welcome to the forum ridgeline.

 

[srs713]

A small problem with choosing grades of fuel comes from the physical structure of most fuel pumps.

One hose dispensing multiple grades of fuel using a selector valve inside the pump housing.



Standard 3/4" hose, at least 16 foot long from the selector valve to the nozzle means that you are getting...

(pi X (3/8"^2)) X (16' X 12) cubic inches of whatever the last guy chose.

That's about 85 cubic inches of fuel. A little over one third of a gallon you have no control over.

I remember back in the day when I used to read those Mad magazines and those funny fold in covers. One I remember was of a gas station with 3 different gas pumps of different grade gas. Fold the cover and the picture showed the pumps all connected to the same tank underground.

Lol. I read that same one and that image pops into my head anytime I purchase any grade other than 87.
