As soon as I took off the lower half of airbox and saw the rats nest to get at the valves, I opted for leaving and capping hose. As I see, the minimal weight reduction is not worth removing.

Yes, as Aaron demonstrated in the first post (you can read the colour bands on the resistor in the picture to verify). 24R is also smack in the middle of the correct resistance range for the PAIR solenoid according to the service manual.

I see above mention of capping hoses (plural). I just capped the one hose that connects to the airbox. Am I missing something? Should I have capped two? I don't see any difference in doing so.

Nothing has been noted that the top of the 650r engine is any different around the exhaust area.

You'll need the resistor to trick the ecu. Unless you're not removing the pipework.

Will be removing pipeworks, no need for it, so will be looking for the resistor, pretty sure it was mentioned earlier what kind i need.
will take the chance and order the block off plates :stop:

From the service manual, is this info useful?

STANDARD: 23 – 27 Ω (20°C/68°F)

It's sounds much nicer with them blanked off - but only do that if you have removed the stock exhaust and replaced with one that does NOT have a catalytic converter in it.

Block off plates from smart moto - Greece, arriving in a few days.

Will be getting the akra later on, maybe not until next season.

Is it a no go to install the block off plates with stock exhaust on my cb650r 2019 ?? Does hurt something ?

Get a set of JIS Screw drivers. Do NOT strip the air box intake funnels screws!

Will be having JIS screw drivers ready.

The point of my last post was really about stock exhaust and pair valve block off plates, why is this combo a bad idea ? Does it mess up the cat or something ?

Edit: removed stupid question on JIS screw drivers vs phillips.... :]
Thanks

Yes! It will ruin the stock exhaust. The pair protects the catalytic converter. Having said that do u care about hurting the cat ?

Oh wow, i will just have patience and wait for the akrapovic exhaust before applying the block off plates mod.

Dont want to ruin the stock exhaust cat, who knows - might sell the akrapovic seperatly one day, in that case it would be nice to have a fully working exhaust to put back on.

Thanks guys
