picked up my new (for me) '05 FJR. 10,000 miles stock except for corbin seat and handwarmers.

very impressive torque curve (seems more like a line)

dumb question #1: how do I remove the Corbin seat? it looks like a single piece vs. 2 piece for stock.

dumb question #2: premium or regular gas recommended by yamaha?

thx in advance for any help.

Welcome to the world of feej ownership.

As for gas, I burn high octane. Believe that is what the manual calls for.

 
1) Put the key in the seat lock and unlock it. Its just ahead of the top of the passenger foot peg bracket.

Lift up the rear of the seat and it should pull away from the gas tank and come off.

2) The owners manual suggests regular (87 octane) covered in the '03-'05 Bin-O-Facts (Gen I): Linked Here

 
found the lock but it seems the rear rack must be removed to move the seat far enough back. can anyone confirm the rear rack removal is required to remove a corbin seat?

Please don't put premium gas in your bike. And the fastest answer that I can give you is that Yamaha says 87 octane and that's what the compression of our bikes are designed to run on.

Like I would tell the kids at school "Don't try to make the rule just follow the rule" 87 OCTANE

Paragraph 1, 2 & 3 https://auto.howstuffworks.com/question90.htm

 
The corbin seat will clear the rear rack. You just have to sort of push the seat forward and sort of pry it past the rear rack.

It will come with a little wiggling

My corbin would not clear the givi rack, had to gently pry the wings on either side of the tank apart, then lift up.

 
congrats on the bike !! I own the same year 87 octane ratinf and sorry no corbin seat yet Winter up here in calgary again let me know how you make out!!!! :rolleyes:

 
they love ethanol and other weird additives here in CA year round, and in winter they add even more of the stuff. To get a decent amount of gasoline, I need to go to 92 until the "summer blend" gets here. Chances are they might not make it anymore, or they'll make the current stuff the new "summer blend" and give us an even less potent brew in the fall/winter/spring months.

 
I run the lowest non-ethanol octane I can find. Locally it's 87, but I think I found 85 in the CO mountains on my trip last year. No additives (that I buy). I've had zero issues.

Seat- hopefully you get it figured out. I have a Russell :)

 
Unlock the seat.....

Lift the rear and push back as far as you can rearward.....

Persuade the front of the seat to come up......

cuss Corbin......

repeat, and the seat will finally come off.

It is a learned technique.

OH........and then you have to LEARN how to get it back on the bike.

The one-piece Corbin is not one of their better designs.......fine to ride on.....but a real pain in the ass to get on and off!

 
The gas tank will move just enough to make it impossible to get a corbin seat off. Loosen the two 10mm bolts at the front of the tank and it should slide a little. That will give you the clearacne you need.

And as far as gas goes, nobody can tell me to run anything except the highest octane I can find. I can hear and feel the difference when I run lower octane fuel. You should run what you like.

 
The manual says 87.

I get better mileage on 87 octane.

I can feel more heat on 92 octane.

I can't hear any difference or feel any difference in power, like I could on other bikes.

So I pretty much run regular, with an occasional shot of premium when I'm riding during mid-winter months.

By the way, you know there is no such thing as a stupid question...there are many other factors that don't appear on a label at the pump that affect how gas burns in your engine, starting with the source of the crude, and the vapor pressure of the mix, and the type of additives, etc. You can research it on the internet, or discuss it with a chemist or a CE over a couple of beers, but I think the octane rating is largely a marketing ploy with respect to modern engines.

Try running a very high-compression engine, or one using forced induction (supercharger/turbocharger), on low-octane fuel, and watch the vehicle's ECU retard the hell out of your timing so you don't get a ton of knock/predetonation. If your engine is tuned to run on high octane fuel, running lower octane is not very smart. The FJR is not tuned to run on premium, so it doesn't really matter what you gas you put in it as long as it's not a high percentage of ethanol and not full of water or other contaminants.

My Corbin seat must be removed by prying the front away from the tank. It won't clear my Givi rack at the rear. You'll get the hang of it.

As for fuel... 87 octane.

 
I don't have a rack in the back and still have to pull the seat by the front. I pull on both <wings> of the seat and take it out front first. There is no way it come out by the back first...
