To chop or not to chop..

[Jgspahn]

So with the mods in my sig, im running a 310 main, but i dont know my pilot.. i will know it tomorrow when I dig into the carbs. Heres my question(s). Ive been using the search bar and researching plug chops. There seem to be mixed reviews on whether to do them or not. My preference would be to not do one because i never have, and would rather watch someone else do it before i went in there thinking im the expert and try it myself. My bike seems to be running ok I GUESS?? This is my first banshee and ive only rode it for about an hour. The carbs are synced with a sync tool btw. There does seem to be a slight bog in first and second when you just start to press the throttle (like for just a split second). Are there any telltale signs that it may be running lean? What do you guys recommend?

 

Im in Mississippi @ about 100ft.

No need to do a plug chop. Have you done a wide open throttle plug check? That will tell you everything you need to know about your main jet. Just run the bike wide open in 4th or 5th gear and then shut the bike down. Roll to a stop and let it cool off for a minute. Pull the plugs and look at the strap. White = lean. Black = rich. Tan = just right. Adjust accordingly. Assuming you have aftermarket pipes, you should be at a 27.5 or 30 pilot.

Im gonna devote all day tomorrow to tuning it in right. I rode it around the shop today.. Didnt wanna idle, sounded fine but would just die after about 15 seconds of standing still.. also it bogged in first if you slowly or normally got on the throttle.. if got into the throttle early and hard, it seemed to run fine through the gears.. What do you guys think? Ive got 310s in it now, dunno what size pilots.
