Screw Between Throttle Cables

(1/2) > >>

Does anyone know the part number for the small screw between the throttle cables ( bar end ) on the underside of the body - I had a real job getting this out as the head was chewed up - I have looked at the Honda drawing/parts list but cant see this on the drawing- I have found the part numbers for the longer screws that hold the body together  - but this screw has got me stumped - its only about 8mm in length - not even sure what purpose it serves ?- locks the throttle tube in place ?

Just a random thought, millions of years ago I owned a CB750, which as we know, uses the same/similar switchgear and twistgrip.  In the location of your mystery screw was a thumbscrew which you could tighten/loosen by hand to increase/lessen the amount of friction on the twistgrip. You could set it to become virtually a form of cruise control and ease the strain on the wrist. Probably worked well in places like the USA where you could ride for miles without having to change your speed. I can only imagine that the screw you are looking at is just a blanking screw used in the casting, which probably has not changed.

The same for the 500,

I use it to set a fast idol to warm up while I put my hat on.

Thanks for the comments - Does sound like it is just a blanking screw - It was only once I got both the longer screws out holding the body together that I realised I probably didn't need to extract it at all  - all the screws were really badly chewed - I suspect from non JIS screwdriver being used in the past - I had to cut a slot across this little one - and when i finally got it out and saw how short it was assumed it had snapped off - but there was nothing left in the housing - so I expect its just a blank and is not long enough to reach into the throttle tube - as an aside - fitted new throttle cables (after the 'pull' cable snapped ) - and the difference in how the throttle is working is massive - the old cable must have been causing massive drag before it let go and snapped the nipple off ! - a real eye opener as to how much influence the cables have on the feel of the bike -

Imagine a large fossil of a SOHC in the science museum in centuries to come! ;D
