Valve Check/Valve Adustment

[Gprider]

Is there anyone here that lives in the DFW area that has a trusted mechanic that has done FJR valve checks. All of mine have disappeared into obscurity.

Valve checks are easy to do. Adjustments are a little more complicated, but FJR valves are usually in spec. I'd install blockoff plates while in there, makes your checks so much easier.

Without blockoff plates:



With:



Otherwise, Monkeywrench cycles in Arlington (I think) has been good for me and others in the past.

So all those hoses you eliminated arent necessary at all?

I've got 32,000 miles on my 2016 FJR. My 3 other FJR's were all in spec at the first valve check, so I'm not too worried about it. I've done a valve adjustment on my 95 vmax, but that is a different animal than the FJR.
Where would I find the block off plates?

Having just completed a valve check/adjustment on my V-Twin KTM, the FJR is much easier to get into than that, I'd imagine a V4 even more complicated. The only fiddly bit about the FJR is the water pipes on top and if you need to replace the O-Rings. Somewhere in the forums is the specs on them that you can pick them up at your local hardware store.

As for the blockoff plates, I don't think the guy who made mine is doing them anymore. A quick google shows that Revzilla has some from Driven, and there's a few other folks selling them out there. "Yamaha FJR 1300 AIS blockoff plates" is what I searched.

Do NOT even consider not replacing the o-rings on the coolant pipe. They get squared off and hard and will very likely leak.
Blockoff plates are available commercially but inmate @Festus was planning to make them and offer for sale. Don't know if he went any further with it or not...

+1 on replacing the o-rings.

One note on 2016-up, if you remove the PAIR solenoid, you'll get an error code (because it's missing). The cure is either leave it there and hooked up (no need for piping), or find a suitable resistor to put in the circuit.

The o-rings are 2-116 n70 Buna material.

This is the first I've heard of this. Don't even know what a PAIR solenoid is. I watched Two Wheel Obsesion's video of a valve check, but his is a 2014. No mention of the PAIR solenoid.

See gixxerjasen's post #2 above. First photo, all those hoses and the solenoid in the middle is the PAIR system. Passive air injection into the exhaust ports is designed to burn unburned gasses downstream in your exhaust system........ removing the solenoid had no consequences 2015 and prior, only after 2016 when the ECU needs to recognize it's there (or a resistor).

If you remove the hoses, there are 4 adapters on the valve cover which you remove and replace with block-off plates. HMFWIC might chime in and advise where you can get some.

Also, IIRC, there's a thing that needs cappped off somewhere. Airbox maybe?

Duh, right there at the bottom of my picture.

Do you guys know what size cap is needed for the airbox after PAIR removal? Need to get one before Intech Day at FYB's.

Look in this video description. I got an assorted set from the hardware store IIRC, but it's been a long time.

There is a hose with a cap in it. Cut the hose shorter and put it on the airbox.. done. If you don't replace the fittings on the valve cover with blockoff plates, then yes, have to plug them somehow.

I just used super 33.
