Seized throttle cable assy

[EddieMello]

My poor 175 has not been run in 30 years. It appears to in pretty good shape in many respects but the obvious problem I have is the throttle cable assembly does not want to move when I turn the handle bar throttle grip. I don't know if the grip is the problem or if the slide is stuck in the carburetor or maybe the cable in between. Anyone have ideas as to the best methods to lubricate these components? I know the manual says to lubricate the cables frequently but I am not sure how that is accomplished. I did squirt some WD-40 into the 1 into 2 cable housing and I could squirt some 'carburetor slide and linkage cleaner' into the carburetor. Not sure about the grip, I hate to take it off if I don't need to. Thanks!

You can remove the two screws in the throttle housing on the handlebar, lift off the top and get some lube into the upper end of the cable without actually having to remove the cable.

For a thorough lube with any cable unhooked at the upper end, use one of these: http://www.motorcycle-superstore.com/4838/i/motion-pro-cable-luber?suggest=1&term=cable%20luber

Thanks guys, that is very helpful... now I wonder if Richard has some screws that I need?

              If you need 6 or 8mm screws, you can buy current ISO screws from anywhere and they will fit.            BS used JIS pitch screws for all other sizes so you will need to source from Richard or elsewhere. Standard ISO pitch screws do not fit.  Here's a link to the definitive guide to BS screw threads, see post by Disc Valve at the top :-
