What should my Jetting be?

[Dinner]

Hey everyone...I have an 87 Banshee, and for a couple of weeks i have been taking that carbs apart because...the left side loads up so much (I Think) that as it is idling it will start to mis-fire, once it is warmed up and you give it gas, it stops firing and just shoots the gas/oil out the exhaust...and its not electrical cause i have switched the cables and nothing changed...when i first start it up it runs like the right, but then gets worse and worse....so my question is..is my left side jetting off so bad that its loading up so much it fouls the plugs as its running?...And what should my jetting be at (Roughly)?

 

Mods:

Main right now-270

Temperature around -5, -10

Not sure what clip the needle is on, or what size the pilot jet is

 

Be working on it hopefully tomorrow afternoon

Thanks for all help!

you might try a 27.5 pilot

needle 4th clip

 

310 mains with the cold you could bet for 310-340 have to do some plug chops

For the winter, I run 370 mains. FMF Fattys, K&N, lid off. Needle stays in 3rd clip position. If I put the lid on, it's stumbles at WOT with the 370s (rich). With the lid off it runs great, so I stuck with 370s.

 

You can also do the choke trick. Warm the engine up and pull the choke out half way (half choke position). If it runs better at WOT with the choke out, you're lean.
