Can anyone let me know which slot the clip should be fitted onto on the needle valve of a 1980 XT250G?

Thanks Nick

Hi Nick,

Don't know exactly what set up your've got on your bike but as a rule of thumb for a standard airbox and pipe

the clip usually goes on the middle slot then its just a case of tuning the carb to get the best results for your bike if you have standard jets in your carb?

hope this helps

Thanks Bill - bike is completely standard with it being just rebuild for new cam chain/bearing, and I fitted a Keyster carb refurb kit when stripped the engine.

It coughs and misfires when the throttle is opened and will not rev, so wanted to make sure I had put the circlip in the right place.

I am going to check the float height as it feels like fuel starvation but wanted to be sure I hadn't got the needle setting miles off.

Thanks for your advice Nick

According to the Yamaha service data book i have the XT250 needle clip position should be in the 3rd groove down from the top. Main jet #165. Air screw 2 and 1/2 turns out. Hope this is of some help .Tony.
