Title: K1100LT Throttle Screw - Cruise Control
Post by: mcvicar on August 31, 2013, 04:42:52 PM
Just curious as to whether I should be worried or not?

I was out on a great ride today and used the throttle screw on a long section of motorway as a cruise control.

As I came off the motorway I slackened off the screw to regain control of the throttle, as I normally do, and the throttle completely cut off.  I ended up coasting to a halt, luckily on to the slip road by then!

The throttle seemed completely disconnected, and I assumed the cable had snapped, however I had a fiddle, unscrewed the adjuster at the handlebar end, put it back together again and hey presto, all worked fine!

I am now nervous of using the throttle screw again, in case this recurs.  Has anybody come across this before? I rode the remaining 50 miles home with no problems but don't know if I should be worrying about the throttle cable giving out the next time I go for a ride...

I would also like to thank the two young lads on 125's who made the effort  to stop and make sure I was OK, still on L Plates but obviously showing the right spirit!

greetings mcvicar...

you talking the throttle lock thumb screw on the right handlebar perch...

i use the screw to put enough pressure on the throttle tube to hold the throttle tube in place butts can still rotate the throttle closed by hand... thats how i do it... close the throttle then loosen the screw...

so you are saying you had lotts o pressure on the throttle tube... and when you unscrewed it to releive the pressure the throttle snapped closed... butts your throttle cable came off inside the perch... is that right...

if it didnt come off and you simply adjusted it with the cable lock nut under the rubber sleeve under the perch... well... thats what that adjuster is for after all... to adjust the metal throttle cable inside the rubber jacket...

Yes, that's the one.  I have heard it described as a poor man's cruise control...
