Unidentified port on 2021 GP1800R

[tman701]

Hey guys,

Just went for my first ride on my new 2021 GP. When I got home i took off the seats to clean the engine and surrounding areas and noticed this little do-hickey on the engine cover. There is a clear line attached to it underneath that goes to the intake elbow. Haven't noticed it on any other GP so not sure if its a 2021 thing or a dealer installed item. I'm guessing the latter because my GP came with cleats on both sides but no other GP that I have seen has them either. I figured it might be for fogging the engine when winterizing, but there is no such thing in Florida, lol.

Fogging port you paid extra for and didn't know it...

Lol, i don't doubt it.

Yup... Looks like a dealer installed fogging port.

I would expect the dealer would have included some customer instructions or paper describing what that is and how to use the fogging port(s).

Wow, interesting, did not know that was a thing. This also explains the pop-up cleats installed which was a nice surprise. To be fair to them, we ran into an issue with Yamaha that required some escalations up to corporate to get things cleared up. So what should have been a 30 min thing took us almost 4 hours. So i don't blame them for overlooking those minor details.

The limitation with spraying fogging oil down the spark plug holes is that the oil doesn’t mist onto the backsides of the exhaust valves. The engine is not running and even bumping the starter motor while spraying isn’t going to move much oily mist out the exhaust valves. By the time the spark plugs are reinstalled and the engine cranked a few turns that oil is a semi-sticky liquid on top of the piston, no longer a ‘spray’.

I have yet to see a tidy method of getting fogging oil spray directly into the throttle body intake on SVHO engines. The throttle body is downward facing and not easy to get a spray nozzle into, even if one was to wrestle the J tube out of the way.



I suppose the fuel injectors could be backed out and then spray the fogging oil into the (non-running) engine that way. Doable, but I would prefer to not mess with the fuel injectors and related stuff unnecessarily.

What is the ‘best practices’ method for fogging the SVHO engine?
Without also fogging the intercooler fins
