Hi:
I went to start my 1973 -850 ccCommando, and turned the throttle. It somehow lost its return resistence, like it may be stuck wide open.
Any suggestions on what this is and how to fix it- not much of a mechanic.
Thanks,
John
Hi by not much of a mechanic do you mean you do not know how the cable is made up if so ...It runs from the throttle grip (single cable) to a 1 to 2 connector under the tank (It is a small cylindrical piece about 2 to 3 inches long ) from the other end of this 2 cables run to the carburetors (I am assuming you have 2 carbs

)
1. If the carbs are stuck wide open you should be able to get hold of the cable going into the top of each carb and pull it up with no resistance. If there is resistance then when you let go it should snap back as the throttle slides are pushed back down by the springs.
2. If this is not the case then best bet is to remove the tank and check the complete cable it could have frayed or gummed up.
Depending on the length of your fuel hose you may not have to totally remove the tank but lift it up (after removing the tank bolts) and prop it off the frame with something soft.) This may enable you to get to the cable junction and carefully ease it out from under the tank to check it out.
One last thing to free it you may decide to use WD40 thats OK but after make sure you run some oil into the cable WD40 is not a lubricant .
