Short run out on the 961 SF this afternoon must have done about 400 miles on it since buying it Nice long straight out of a junction and pinned it open up to 80 or so then shut off except it didn’t —- throttle jammed full open, Kill button and cruise to a stop . Calm down a bit and can see the throttle spindle is jammed open. Get home and strip it down to find a shop rag sucked into the left side throttle tube jamming the butterfly full open, easily fixed but careless from whoever was last in that engine ( not me), funnily enough feels a bit quicker now also Spike
 
Spike that's a bit how's your mother, bet pulse rate got going a bit :oops:, shame on the mechanic!
In young days I made up an ES2 in a Aerial Huntmaster frame, hot cam bigger ported head with a Monobloc, anyway wound her out along a good stretch of highway, backed off and had the same response, no kill switch only way to stop was turn the fuel off and wait, it did wake me up, the thread on the carby had stripped and the slide came out.

Wow, that's frightening. Thank god for kill switches. Perhaps you should feed that back to somebody ?

Huge pucker factor.
 
Seem to remember a race possibly the Ramsey sprint on the Isle of Man where a bike trashed itself and very almost its rider in the same circumstances. Well done that you had presence of mind to hit the kill switch.

Suggest you remove the repair shop from your Christmas card list immediately. Harsh but fair.
