There is technical and practical applications.
When using a fork, the practical instruction is to make sure the tine end is opposite your hand, and not to stick the tines in your lips or gums. That's it.
On the technical end, I'm sure someone can write a 400 page technical manual on a forks length, balance, tine spacing, number of tines, material, corrosion resistance, and a 100 other things. Which in the end, is really unneeded/useless information, in actually using a fork.
As far as practical use, float height/fuel level, only has 2 purposes, 1. To regulate the fuel amount to feed the engine at all throttle positions/RPM. 2. To make jetting consistent, as fuel height differences changes the fuel weight, which in turn effect jetting. That's it.
It seems Mikuni (and other carb manufactures) have a "range". that allows changes without having to change the jetting. And if the floats are set upside down, on their side or by fuel level, if you actually use that range, they will be in spec.
I would also say few and I mean few motorcycle dealers reset float height on hundreds of thousands of new bikes. They wouldn't take on the shop cost. And if it was so bad, no new bike would run worth a crap, and we know that wasn't the truth. I
The only thing one really has to look at is not changing the float level radically, as that will change the jetting. Other than that if you are in factory range, any method works the same.
And Rod, the BFD wasn't directed at anyone, it was directed at why over-complicate a super simple, quick, and accurate process? 2 minutes and you are done with the upside-down adjustment.
And the fact is, when a motor is running and the bikes is being ridden, the fuel in the bowls is all over the place anyway. Vibration, fuel being used/added and the bike leaned, accelerating and stopping. Any minor difference in adjustment is not going to cause any problems..........
