guys I'ma leave off the fork and shock upgrades until I feel the need for them.. I'm not experienced enough or pushing the bike enough yet.. no track days for me so riding on the street and going ramping hasn't really got me thinking about it for immediate upgrade but for the future list.

I DO however need some help with carb/jetting!

I have Aliexpress slip-on exhaust (Baffle was on.. but took it off for now)
K&N hiflow air filter (installed by one of the previous owners)

Today.. I finally took the bike to DIY shop to install DYNOJET stage 2 kit along with size 40 pilot jet. (Stock size at 38) Also changed out spark plug to NGK CR8EIX (iridium or whatever..)

Installation was huge pain in the rear and omg... that airbox...

Got rid of Snorkel as instructed.
Installed the provided needle along with 96 size dynojet main jet as I wanted to keep the baffle on the slip-on. (I believe size 96 was recommended for stock exhaust..)
Installed 40 pilot jet.
drilled out mixture screw cap and seated at 3 turns out as instructed from the bottom.

Issue now is that it seems to be running too rich on the low end as it's slow on the pick up when I turn the throttle hard.

Should I go back to stock pilot jet or is there other way to fix the issue?
I feel it should be alot more responsive..
