As someone with a Goldwing in his future, I was impressed with the resilience of the Wing. It endured a ton of abuse and kept going.
Which is typical of car/bikes/trucks made in Japan.

Watch This Honda Gold Wing Do Some Serious Hill Climbing And Tumbling
If Honda Gold Wings and off roading aren't usually things that go together, then Honda Gold Wings and hill climbs seem even more bonkers. Watch what happens.

I think he needed a extended swing arm like the 450 then it would have been a race! haha. Youthful exuberance you got to love that. I never had the money to throw bikes away like that but we used to do the same stuff on a old Harley sportster a Honda 650 and a Suzuki 450. We had to ride ours to get home though so we definitely tried to keep them from flipping down the hills. haha.
I'm tellin' y'all. . . . pay attention the feel, not the sound. She'll tell you how she feels.

I'm a big believer in high RPMs. I do it routinely, but was pretty surprised when I got my bike back from the valve check last week, and was told it had a "lot" of carbon build up. Actually I was shocked. I can't ride it at any higher RPMs. Talked to the tech, he told me it was due to today's fuels. I always run premium, but still not good enough. I need to find that Yamaha fuel treatment product and start running that in every few tanks I guess.

I use that fuel treatment every few months. Seems ok so far but im a ways from a valve check.

Hey “DirtDad”,
The following is from a previous comment I posted, which may help you;
“However (as a little background) shortly after I purchased the bike (at 32k miles) I had the cam chain tensioner replaced. While the mechanic was in there he scoped the engine and said the prior owner must have been using low grade fuel because the carbon build-up was extremely thick on the cylinder walls and on the valves. This mechanic was a Gold Certified Yamaha Service Technician at the Colorado Davis Service Center in Montrose, Colorado. He advised me to add Yamaha’s Engine Med-RX to every fill up. The part info is below.
Part # :ACC-ENGIN-RX-16
Part Description: ENGINE MED RX 16OZ
I have used this product on every fill up since then, and my bike runs like a Yamaha should, “like a bat out of hell”.
Good Luck and Keep the RPM’s Up!

As much as people may not think that, the biggest contributor to carbon buildup in your motorcycle engine has less to do with fuel and RPMs but more to do with the engine venting.
Have you ever noticed that in your air box oil will build up. This is due to the engine valve cover breather via a hose connected from valve cover to the air box that allows oil vapor to escape the engine block and enter the air box.
This oil build up is normal BUT at higher RPMs the oil vapors are amplified and this goes directly back into your engine where it is burned not as a fuel but as oil.
Thus carbon buildup, oil doesn't burn like fuel and generally will deposit on pistons and valves.
Unfortunately motorcycle have the most basic recirculating engine breather systems compared to the automotive systems, you want to help prevent so much carbon buildup in your engine, run good fuel and disconnect the block breather from the intake.

Thanks, guys. I have not noticed any oil levels dropping as a result of routine high RPMs.
It is the Yam MedRX stuff I remember seeing being purchased by the case by some. I may join in on that practice.
About 20 years ago my airplane mechanic told me (unofficially) to use Marvel Mystery Oil. I forget why it was his recommendation, but it wasn't for carbon.

On a healthy motor your oil level really won't change much between oil changes but it will, it has too, all internal combustion engine burn oil from new. In this case its a mist that once cooled falls into the air box, normally you may get about a table spoon in the box but some does get pulled into the intake. It doesn't take very much to start the process of carbonation, little at a time it will build up.
Fuel also causes carbon build up, generally the use of incorrect fuel will be worst but it is not the main reason.
Also will a cool running motor cause carbon build up, it is a more common issue then fuel. So is prolong idling and warmups.
The other thing is oil carbons are heavier and stickier then fuel carbons. In most cases fuel carbon will blow out the exhaust under a load but not so much oil carbon deposits.

I just got done looking in my intake this morning. The intake valves look like they only have a few miles on them even though it is 100000. Even the left cyclinder that seems to suck more crankcase oily vapor through it looks perfect. I have no idea what is on the exhaust valves though. I had a Honda XR that vented to open air and it would build up carbon on the valves with just a few hours riding. Not sure why because it didnt use oil to bad. I think the head on that bike ran super hot compaired to the other things we had.
