Today I am installing MikesXS Non-vacuum petcocks on my single-petcock '83 and '80 Specials.
Forgive me if this is all repetitive, but I thought that at least some aspects of the install might be helpful to somebody.
So, here is the unit on my '80, which works fine, but I'd rather go Non-vacuum for the obvious reasons.
As you can see, the ideal is to aim the gas with a 90 degree fitting towards the center of the bike. The new petcock comes with straight and 90 degree fittings.
However, when I tightened one of the 90 fittings all the way in, it was angled at about 2:00, not at all ideal:
This angle is best, but some sort of modification would need to be done:
The other Mikes' petcock tightened to an angle that was worse, 7:00. (not pictured)
However, adding extra filtration is a good thing, and a 90 degree filter attached to the straight petcock fitting (provided) will fit into the chassis fairly well:
For accessible connections, I use stainless safety wire, which gives me peace of mind.
No need to drain the gas if you have 1/3 of a tank or less, just prop it up with a gallon oil bottle:
Clean the tank connection surface,
and use new sealing washers and screws. Dirt cheap at Mikes:
The sealing washers go onto the screws VERY tight. I grab them with my fingers:
No need to use any sealing goop, in my experience.
Installed:
The filter tucks in fairly well. As you can see, I wrap the safety wire 3 times, and twist. Not too tight, tho.
Hope this is useful to someone.
