Hi I want to change the carb jet on my sons bike, is there any drawings showing the jets location and do I need to take the carb off ?

You  will need to drain the gas from the float bowl, remove the carb,, and remove the float bowl from the carb to access the jets.  Why do you want to change a jet?

Same reply whether it's a 2T or a 4T : You  will need to drain the gas from the float bowl, remove the carb,, and remove the float bowl from the carb to access the jets.  Why do you want to change a jet?

to get some more power.  I have changed the variator rollers to 7g ones, that has improved things (the ones removed also had massive flat spots!)

Thinking of a Leovince TT exhaust unless  you can recommend anything else.

Hejust wants to go faster!

Just get the new exhaust , that sh** will spike the Super 8's performance Heavy , like double the torque from stock exhaust  - and jet it to about 86-88 with the new exhaust.   Exhaust and jetting is huge ,,, maybe throw some  gram Sliders in their.   

For jetting , just unscrew and remove airbox first -- then take off Throttle carb cap , gas line , and unbolt the carb. Once unbolted disconnect the e choke --- Flip carb upside down - unbolt bowl.. Maine jet is the one sitting higher  , closer to your face , unscrew it and put in a fatter one. 86-88 for expansion exhaust -- Keep air filter on bike.     JEts to use are 4mm keihin round jets .... stock part # 99101-116 - Jets size # .
