If you want hotter fuel, Sunoco GTX is 98 and the AMA Pro spec fuel. I buy it in 5 gallon pails for an R6. You have to contact Sunoco Race Fuels to learn their distribution. I buy mine trackside or from a gas station about 30 miles away. Sunoco GT is 100, but oxygenated. Prolly don't want that in your trailbike.

What's the price per gallon for the GTX? I don't really need a super high performance fuel, just a non-ethanol premium would suit my needs. Of course, that sweet smell of 100LL when it burns is worth a few cents per gallon!

Mind you we don't use race fuels in street bikes, but the 5 gallon pails of GTX cost $65 and trackside is generally about $10/gal out of a pump.

I might add that our race bikes are mapped for the 98. Not sure it means much, though. A stock R6 makes about 100hp at the rear wheel. The fuel and pipe brings it up to about 107 for ours. The motor build and related kit electronics pops that number to about 120hp for us. The top teams get another 10hp above that or more (or so they say).

Seems sort of futile on a 250cc commuter motor...

Agreed...I'll keep paying $5.30/gal until some non-ethanol premium is available locally. I'm just glad the little WR gets 50+ mpg

There's a guy in the Crowsnest Pass with a WRR. Blairmore, I think. You'll find him over on the WRR forum; don't know if he hangs here. And a couple of people just inside the BC border.

Must be a few WRR's around Calgary/Lethbridge/Edmonton.

I have been hemming and hawing on getting something like this. For 2 reasons I've not: 1- I've been on the GSA for most all of my trips to date (has a center stand), and 2- I've always figured I'd get lucky and just have a tree stump/rock/whatever to prop the bike up.

Now that I'm planning a bit more with the little bike especially when we get back to the states, I should probably do it.

This thread is ridiculous, there've been like 3 pages of posts in the past 2 days!

I'm still back in the 900s getting caught up...

Just a thought about using Av gas 100 LL. It has way more lead in it than any leaded auto fuel you could buy in the past. I know its says 100LL (low lead) but it is not.
I use it in my plane but its because that engine requires it. If you have not done specific research on the potential problems using leaded gas it would be a good idea.

+1 Wouldn't recommend running 100LL (Avgas) in the WRR. Significant lead content....I know, cause I used to make it as a refinery engineer. This 4-stroke WRR motor is designed for unleaded fuel.

Its ok in a pinch. I mean, if it will burn, it will run....whether its methane, ethane, propane, butane, naptha, alcohol, or whiskey. The question becomes how well, for how long, with what consequences? Stick with unleaded fuel.

ok, great responses from all.

Thanks for the info everybody.

I think I'll stick with the standard Premium fuel, and just loose some weight by working out more often.... Less overall weight should help with keeping up the speed......

(I get a 10% commission from Yamaha Japan for every 'damn service manual' sold.)
Can someone tell me which model number to use when ordering from this site? I don't see a simple WR250R listed nor do I see WR25RX(C) which is the other number on my Owner's Manual.

Yeah, that list is a mouthful of letters and numbers. Looks like you have an '08? The service manual is the same part number for all models and years 2008-2011, WR250R and WR250X, California and 49-state: LIT-11616-21-66

I like to play "figure out the code" on these things...normally Yamaha uses a letter suffix to designate model year, so the "X" in your model number indicates 2008; Y is 2009, Z is 2010 and they rolled over to A for 2011 (the model number Chadx gave you is for a 2011, it'll still work for the service manual...)

I'm pretty sure the "(C)" in your model number means it's a California-legal model. Does is (or did it) have a charcoal canister bolted in front of the engine? The other way to tell is on the right side swingarm, should have a sticker saying it meets California emissions standards somewhere in all the fine print...

They've stuck an "L" in the model numbers on the ordering page...have no idea what that signifies.

So, back to your question Under 2008 year, you'd select "WR25RXLC" and you'd be offered a Service Manual LIT-11616-21-66.
