Default Re: 4 stroking at 0 throttle-1/4 throttle

Also make shure your running a correct mix of 32:1 to 50:1 oil to gas

then once you have a good mix of say 32:1 in the tank and running then tune the carb

first make marks on the twist throttle for
half throttle

Once you mark those trottle positions make an arrow on the throttle so it points to the positions wile deiving so you can see where your throttle is and how mutch its open wile riding

if your 4stroking at 0 to 1/4 then its on the idle jet and your air idle screw need to be adjisted , try 2 1/2 turns oit from closed if it stil fourstrokes after more than 2 1/2 turns oit you need a smaller idle jet
Closed to 1/4 is the iair idle screw
1/4 to 1/2 throttle is the idle jet
1/2 to 3-4 is the slide needle and slide cutaway
3/4 to wot is the main jet

thats an easy way to see what jet your on wile rideing and how it needs to be tunned
here to stay and compleatly insane ! deal with it lol
