Yes the rear tail light illuminates
Hi Dylan,
yeah, that accursed "park" position just one small hardly noticeable click to the left of the "lock" position.
(It's there because some jurisdictions require that vehicles parked on the street after dark must display a rear light)
It'll get you and run your battery flat if you don't know it's there.
And despite what peanut sez about how complicated the carbs are
(compared to the single Amal on my BSA, yeah. Compared to the 4 Mikunis on my XS11, not so much.)
you gotta learn sometime, eh?
Read the carb guide until you can quote it from memory.
Strip 'em in a big tray so as not to lose the parts.
Work on them one at a time so the other is a reference.
Grind up special screwdrivers to an exact fit on the soft-as-shit brass the jets are made from.
Trashcan every crosspoint screw you come across and replace it with an Allen head screw.
One last little trick.
The float pivot posts are frail and can snap off like a carrot if you ain't careful removing the float pivot pins.
Mr Hammer is NOT your friend here.
Some use a dykes (AKA sidecutter) behind the pin's head to start it moving.
I prefer using a spring loaded automatic centerpunch (good one ~$20 at a proper tool store) on the pin's tail end to pop them loose.
After the pin is out sand it down so it don't jam in there no more. It can't get out anyway once the bowl is back on.
