Reply To: Identifying Jet needle for my 2005 comet 250
Unless you have the “numbers” of clearances per valve, you won’t know if that’s causing heat issues on the bike or premature cam wear. 15,000 is a lot of rides, so i’ll leave it there. I usually do them at every 4-5,000 miles.
Yes the manual is correct not to tamper with the mixture screws, as then you’re in the abyss. I know what they are but will try to keep this comment short so i’m not quoted incase the bike doesn’t like what i said (modding or stock bikes are not the same, too many variables, hence we leave the stock carb alone and just do jets). Around 3 to 4 is normal on each pot, what the Koreans do factory wise. Your new spark plugs will let you know when they leave a trail color. That’s my comments.
