Thxs Billy, I used the wrong emoticon...

Which ring ( ...mm?) should I use for a regulier oil change?
Thxs

Filsurs,
Take the ring (it is called a crush washer) to the auto parts store and match it up to what they have. Crush washers are sold by the bag. Some are copper, some are aluminum.

E10 has up to 10% ethanol while E5 has up to 5% ethanol here in the UK.
Most of the lads over here use E5 over E10 because it doesn't mess with the carbs rubber parts as much.
It is a bit more expensive but why use E10 when it causes problems.
I've left E5 in my tanks and carbs all winter without any problems though i do regularly fire the bikes up to stop any crystallisation in the carbs.

Be careful of your terms. You are not running E95 95% ethanol in your bikes

You are using Euro 95 (E10), which is 95-octane gasoline with 10% ethanol added for standard petrol vehicles

Apples and oranges

17mm. What's so funny?

Quote from: Pat Conlon on March 18, 2026, 06:43:45 PMFor storage I run 87 ethanol free (clear) gas in my 1380 with 10.5-1 compression. It runs fine for short around town warm up rides. Long rides, hot weather I run 91 E10 gas, no problem....the E10 only plays havoc when I store my bike....I then drain the tank and go back to 87 clear gas if the bike sits for 2 weeks or more. 

With a stock FJ, the owners manual specifies using regular 87 gas. You should be fine.

Stock FJ factory jetting runs lean, when you get a chance remove the #37.5 pilot jets and put in #40 or #42.5 pilot jets and bump your mains from #110 to 115 or 117.5.
 Your bike will run cooler in the hot summer thin air high altitude Colorado locales.

Cheers

Pat

Quote from: RPM - Robert on February 24, 2026, 10:35:03 AMCorrect on the 86/87 model it should not flow any fuel until vacuum is applied. If it is flowing fuel the petcock is bad.

The 84-85 has a prime function which will flow fuel when the selector switch is in the prime position but in the on position it should not flow fuel until vacuum is applied.

Thank you Robert.

I recently had to get a rebuild kit from RPM for me 84 because my tank started marking its territory when I took it off the bike. Put on the rebuild kit and it seals it right back up.

I have to put a rebuild kit in my petcock, it only leaks when you move it to prime .. which I don't do that often.

But has anyone put a inline quick release connection for fuel line, I hate getting that hose off petcock, not sure where it would fit on an 84 model as the hose isn't that long though 

Paul,
I agree with Pat; stainless steel braided brake lines are a good investment there. Those old rubber lines are about done by time, and the braided lines will make the brakes more assertive. I would do the front lines, at least. It will be more complicated with an ABS, but I think we can find you good sources for braided lines here, if you wish. A very good local hydraulics shop *may* be able to duplicate your old lines in SS, so investigate locally, but don't give up if the locals can't help.
Hang tough.   

Quote from: Pat Conlon on March 27, 2026, 06:31:54 PMYour assessment sounds about right.
Stock FJ suspension is too soft, both front and back. Poor dampening.
The front anti dive system is ineffective, always has been.
The stock 16" tires and rims are narrow, heavy and outdated by today's 17" standards.
Stock FJ front Brakes are just ok, nothing special.

Old FJ's don't die....because we modify! 

Add Fork springs, fork valves, anti dive delete and a height adjustable aftermarket shock and the effect will be immediately noticeable. Night and day.
Add Modern, lighter 17x3.5" front and 17x5" or 17x5.5" back rims will allow better tires.
Add R-1 Yamaha monoblock calipers, HH pads, lighter rotors and 14mm m/c with SS lines and they will transform the brakes.

Yes, she's still a big girl by today's sport standards, no getting around that.....
...but now she is a better dancer, much better than the day she left Iwata, Japan... 41 years ago...

Thanks Pat.  Those all sound like nice improvements to make.  I'm just not sure I want to put that much time and $ into that bike.  If it was in pristine condition, that would make sense, but it isn't.  And there are other bikes I'm interested in buying and my wife is already giving me a hard time about keeping 3 bikes around (it's just 3 bikes Honey...)!
