The current jetting is what came in the bike with the fcr

carb and stock exhaust. I added the mid pipe and muff and didnt seem to have any problems, but I just installed the powerbomb head pipe and have not got to romp on it yet.

In the kit:

Main 128, 132, 136, 140, 144, Fuel Needle, E-clip, Adj Washer, Main jet adapter I read theat the kit is made by Dynojet for FMF

thats a dynojet kit for the fcr.you do have a fcr,but thats not the kit you want.you want a JD kit.

the F taper needle in the dynojet kit doesnt work.

What advantage would that be? I took out a 165 and OCD-VR needle it ran pretty good before, just back fired on deceleration and had a mild dead spot on accelertion. Remember I am a jetting tard...My other bike has fuel injection so plug the lap top into the port on the back of the bikes computer and adjust with the push of a button....This needle/jet thing is unfamiliar territory.

the 165 main jet is to rich.the 160 will make more power.

the dvr needle is really lean off idle.

did the bike idle ok previously?

Sounds like you may need to adjust the pilot circuit also. What Pilot air jet are you running and what pilot jet? How many turns out is the fuel screw?

Ok Ok jetting tard I get the point.... 😢

What did the carb come out of originally?

Try turning the fuel screw in 1/4 or 1/2 turn and see if the idle goes up and response improves.
