Jetting For 24mm Oko On 320

Featured Replies

All

I see a few of you have been trying the 24mm oko on the 320 , hows things going , i ditched mine in favour of the sps carb last autumn , bike starts a lot better and runs well . But i still believe the 24mm will give a softer bottom end when set up right , and hopefully set up will improve on the starting issues i had. So i intend to keep experimenting with it.

Can any of you give me a basic guide as to what jets you have been using in the oko 24mm to get it running right , also float hieght and do you blank off the power jet or keep it functional .

I see trial tech in australia are having a bit of sucess with an oko24mm on a 320 , i asked if they could advise me which jets to start off with but i never got an answer.

cheers

greg

hey,

i run on pilot jet 35-38

main jet 100

air screw you have to try (mine is 13/4 out)

float hight standard (19 mm like on a keihin) this is important the bike is very sensitive to this!

check float needle it must be clean

Thanks Bob

Did you ever look into the added flywheel mass , or have you managed to get a shot on a 320 with this mod done yet ?

cheers

greg

jep i have been looking to do this mod to, i have not ridden a bike like this but i'm told by people who know that the 320 with heavy flywheel and 24 oko

is the bike to have if you like 4stroke power.
