AJ,
What Greg said. The reason the throttle should snap back is because
there is a spring in the carb "tower" between the top cover and the
slide. So another thing to check is that these exist and that they are
not slammed, worn out, stuck, or whatever.
Good luck,
Rob

Hi AJ,

If you have the single cable Tomaselli throttle, check these things
(probably in this order):

1. There is a spring-loaded adjustment screw on the bottom of the
throttle. You can set it to lock the throttle in place, etc.
2. Lube all of the cables and be sure they aren't frayed, etc. You'll
probably need to remove the tank and check the 1-into-2 cable splitter.
Best to take it apart, clean, relube and assemble. They do tend to get
full of hard grease after 30 some-odd years.
3. Check to be sure that the end of your hand grip isn't on so tight as
to be rubbing up against the end of the handle bar.
4. Disassemble, clean, lube, and reassemble the throttle itself. It's
not complicated.

Somewhere along the line you should see it moving easily back and forth.

Hi guys,

I had my first riders safety course last night. Wanted to get my
confidence
up before setting out with my bike. I might have a bunch of questions
coming from this class. Only two of us in the class have 70's vintage
bikes. Everyone else has a 2002-2005 crotch rocket or Harley. Depending
on
age. Go figure.

Any way. Told to check to throttle before heading out. Sounds like good
advice. Said it is supposed to snap back when released. Got home checked


mine and no way does it snap back. It pretty much stays where I put it.
Checked both my owners manual (handy little book) and Guzziology but did


not see anything about adjustment. So my question is, does it not snap
back
because that is an nuance of this 30+ year old bike, it never did, or is


there a way to adjust it?

Thanks for your help. Off to day 2.

-AJ
