and machinery, if I can I make the parts myself............... in the dipstick itself sits a one way valve.

Others have also probably suggested you offer these vented dipsticks for a price. You can add my voice to those who have.
If some of our bikes are puking oil due to too much pressure being created in the engine case, and your dipstick mitigates that to the point where it all balances out, and thereby reducing the blow-by to the point where it becomes air only as it was probably intended to be, then some venting should be applied by the factory. But if it's a breather issue and/or seal leak that causes excessive oil emission through the breathers as some have experienced then the stick may or may not completely fix it. But I for one am more than willing to try other things, first, in order to avoid taking it to the dealer to perhaps experience no effort on their part to either recognize it for what it is or competently attempt to fix it.
Either way, excellent work!

A vented dipstick with a one-way valve is fine and will not cause trouble. Without the one-way valve, the engine breather system will not work properly.

The EPA doesn't realistically understand the effects of large displacement VTwins with tiny crank cases and a single crankpin. They regulate them the same way as small displacement huge block car engines, with multiple crank pins.
This is something that they really need to pull their nose out of because destroyed engines and engine repairs cause more environmental damage over time than minute filtered mists of oil.
Thankfully rectifying this issue on our own is pretty accessible.

They unfortunately can't offer such a thing from the factory because of EPA regulations. Venting to the Atmosphere even with a filter is consider excessive pollution.

I'm pretty sure the EPA requires emission of unburned gas and/or oil only from the combustion side of the engine to be routed back into the intake. I am not sure that they would have any requirements for ventilation from the oil tank side of things. That is what I was referring to in respect to a vented dipstick possibly balancing out the pressures within the engine. If they do concern themselves with such a thing I'll stand corrected.

Except that what I believe the EPA is after are unburnt gasses created during combustion. Do those gasses also end up in the oil pan? If so then I'm most likely wrong, and the EPA would see the dipstick vent as an infraction.

They also dont want oil sputtered into the environment. That's why the breather tubes from the breather bolts on EPA compliant aircleaners spit the oil back into the throttle body intake.

True they don't. But a vented dipstick almost guarantees it would not be given the way the hose is routed, coupled with a catch can. Besides, if that was their concern then any motor that leaks oil would be out of compliance with EPA rules. And the owner and/or the manufacturer could face fines.
Isn't the mist/oil coming through the breather bolts created by, or a by-product of combustion? Opposite end of the system, and what I think is the specific target of the EPA. Again though, I could be wrong.
