hi last week i started my bike fz1s , all ok got to my mates house about a mile stoped outside and the bike was reving at about 2000, on a closed throttle. so my mate without asking adjusted the little silver knob on the near side just under the tank. ticked over ok, had a little run out all ok. today went to start the bike had to open the throttle to start it & would not tick over unless throttle was opend a little. i know that its because he adjusted the tick over speed.what i dont know is why it could have revved fast in the first place. has this happened to anyone else.

At a guess on the day your mate adjusted it, you inadvertantly had the choke opened slightly, this would increase throttle opening. So the next time youre out on the bike you use the choke to start, only this time you take the choke off properly and the engine stalls because it was adjusted when the choke was slightly on...a possibility?

sounds like you may need to choke your mate

you can try if you want but i wont.

sorry but the choke is automatic.and it was revving fast when i stopped at his house.
