Hi all,
 
Can anyone please tell me the function of the 2 screws on the underside of the throttle?  They look designed to be adjusted by hand and one of them has a spring under its head.
 
I could take i apart but its working nicely and don't want to disturb it, especially as there are Italian electrical switches & contacts involved!!
 
Thank sin advance
 
Regards
 
Mark

On the Tommaselli throttle on my little Ducati, the one with the spring is to adjust the friction. There isn't a second one, but maybe sets the max. travel?

If it's like the V50 one, the other screw is indeed a maximum travel stop. It saves stretching the cable when looking for that extra 0.5 mph (or 5 mph in the case of a LM)......

If you do take it apart (and it is the same) remember the tiny screw that's buried in the bottom half and bears against the handlebar. It's essential to slacken this off when removing / replacing the twistgrip. Its function is to stop the grip from rotating.

The twistgrip itself is quite a nice design but let down by being made of cheap plastic. I particularly like the clip that holds the throttle cables.

What he said, one is maximum travel stop, the other adds friction so you can take you hand off to do hand signals without the throttle slamming shut. At least so it was in the old days before indicators. Big smile

I took mine off and slung it in the spares box cos it was tearing up the interior plastic rotating thingy.

The one that invariably goes AWOL on a long, wet French autoroute? On the plus side, when it does that it can be safely replaced by black masking tape. Had to do this to a friend's Le Mans in 1986. This was one bodge I couldn't complain about when I bought the bike a couple of years ago!

Ah we mustn't get confused which type we're talking about. Big smile

There's the all plastic one, which includes switches, and there's the Tomoselli one which is diecast metal body. The internal 'pulley' is still plastic tho. Looks like off-white nylon.

I have three of these throttle assemblies, and in each and every one that tiny screw has absented itself.
