Idle issues need help

[Gabrielmq23]

i’m trying to run my 223cc wildcat clone on 94 octane my bike struggles to start but when i put in 87 or 84 it starts first pull

I have the bike running on a 32 but the idle sounds funky it has a regular idle then goes down to about 810 rpm from 1300

pwk28
130 main
32 idle

I tried bigger idle jets but the engine wouldn’t even start up with them (40-50)

The stock wc223 has the piston way down in the cylinder at TDC, with the stock cam, you don't need to run higher octane fuel.
When you say 32, do you mean 32 degrees of ignition timing?

no i mean the idle jet is a 32 it’s tiny but it seems to work better than the bigger ones

Nevermind, I see 32 for low speed jet now.
