Its a generic choke plunger.. Search PWK choke. Ktm/Yamaha/Honda/... etc all use them.. shame on you for still having that cable attached!

2nd that! Go to Yamaha and get a choke assy. for a 07 yz250.

Thanks for the replies, none of my local shops have the plungers for even the Jap bikes, so I got one coming from Halls. X fingers that is my problem.

So I had 2 issues. I fixed my choke and then my throttle cable came loose on the carb and was sitting 1/2 cocked in the opening. Fixed both issues and fixed the free play. Turned air screw 1.5 turns out. Now the bike breaks up really bad after 1/4 throttle to redline. Power is good down low but signs off early and runs harsh. Would this be too rich? I had dropped a clip position in the winter as it was running lean from mid to top. Now it just breaks up and never smooths out.

Sounds rich on the needle. Burble burble. Make sure the new choke is closing properly too.
