Vented externally but what about carbon deposits now?
2022 RKS with 10k miles here.
I recently did external AC venting to avoid any junk in my combustion chamber as it was getting my AC wet after about 3000 miles and I got tired of cleaning my engine cases as oil was dripping from AC over time.
I am sure my bike have some carbon build up as this is usual with this type of stock venting via heads. Here I wonder if I should try to remove some of this carbon build up with Chevron Techron (or some other additive) or rather let gasoline do its job and don't worry about this.
Wonder if gasoline will clean things up over time if I vent externally or some kind of extra cleaning is necessary.
Please share your opinions.
Thank you in advance,

I would venture to guess that unless you see a significant power loss, there's really not much to worry about. Every engine is going to have some carbon build up. Amsoil, Chevron, SeaFoam....all are good at removing deposits, if you're so inclined to fret about such things.
On a side note, you can buy a digital inspection camera like this one, for example:

take a look inside the cylinder, and see for you self if there's anything worth worrying about.
In the mean time, ride it like you stole it and enjoy the good weather.

w/ 10K mileage, I would not be too concerned.
I vote that there is nothing wrong with adding some Techron for a few tank-fulls.
After those thanks fulls, do an engine oil change
PS if you want to go a step further, remove your air cleaner assembly and inspect (then clean) the throttle body blade and intake track for carbon/ oil buildup.

As a teenage lad, I had a buddy whose brother was very capable mechanic.
He had an engine analyzer (SUN?) and would get people's cars running at their peak.
I would sometimes see him get a V8 on the boil, then dribble water right down its throat.
Anybody remember this method of steam de-carbonizing?

Based on replies received so far seems like with such low mileage I shouldn't be concern much and maybe adding some additives before next oil change for piece of mind. I guess this always depends on how much oil is getting in as if it is a lot even with low mileage carbon deposit can be issue if oil amount getting there was significant but I never experienced any white smoke or anything so seems this is not a case
Yes borescope will be ideal here but I might do that during winter maintenance to see what's up there. And yes I heard about water to clean it but this is something one have to be really careful with and I am not willing to try that as personally I never did it and seems this is delicate procedure to do it correctly so I guess ChevronTechron would be my approach.
P.S. I wonder if I voided my warranty by venting externally? I would guess probably???
