well ive come to find out jetting this thing is no where near easy as my honda was its currently jetted with a 182 main 50 pilot and i think the need is 2nd maybe 3rd from the bottom, running the rossi exhaust open lid pro design adapter and foam filter running 110 cammed and 13:1 piston getting alot of popping when i let out of gas at high rpm, any help would be greatly appreciated

Since your fuel airscrew is the easiest thing to get to (provided you have the ziptie) see where it is. Should be 2-3 turns out from closed. I would think she's running alil rich on decel. Also, you may want to go down on your pilot. Do you have any portwork done? I'm only running a 45 pilot and look at the bottom of my motorwork. Hope this helps

i had mine at 48 pilot, fuel screw i think it was 2 turns out, and the stockmain i think it was a 158. when i put my esr pipe on there, i had to go all the way down to the stock 42, fuel screw 1 turn out, needle in the 4th clip and a 172 main, and it is rich still. so gonna drop the needle another clip and try a 170-168 and see how it does. a rule of thumb is if you are more than 3 turns out on the pilot the jet is too small, and if you are no more than 1/2 out it is too big.

I get ALOT of popping too, its mainly becasue my air filter is dirty! when i put a clean k&n in, the popping/backfireing goes away completely.....
