Just out of the blue my hot start seems to have froze.
The cable moves a little with the plastic nut on the carburetor removed.
Just I can't seem to remove the cable and plunger out of the carburetor.
I have a owners service manual all it says.


Any thoughts on how to get the plunger out of the carburetor with out busting it up?:applause:

This is a FCR2 carb maintenance issue. This will happen to any make of bike that uses this carb. I apply assembly lube to the hot start plunger about twice a year, since it can get oxidized. After 132 hours, I actually replaced the plunger and seal due to wear.
