Jet size??

Hi,
How do i find out the jet size of my runner without taking it all apart, and what size should i want it to be about?
Nice one guys

 

why do u want to upjet? what mods have you done etc

 

if it runs right then leave it alone.

 

well im not sure if it does run rite....
when i first turn the bike on if i rev it then it will cut out... i can only assume this is due to the engine being cold as if i leave it for a while it will be fine.
Cheers

 

it is indeed because it's cold.

 

is ther anything i can do to speed this up as it takes quite a while??
Cheers

 

not unless you want to bugger the motor. it should be at least 5 mins before the bike is fully ridable. try cleaning the carb and making sure the choke is working properly.
