Gas Gas Cadet 80 / Rookie 80 Tuning (2005 - 2012)

Dellorto PHBG 21 Carby 

These bikes tend to foul plugs when used in Australian conditions with the standard jetting. We suggest the jet set should be as follows: 

 Needle position:

The needle clip should be in the leanest spot (Highest groove) 

Pilot jet:  (standard supplied is 50). 

45 jet is better, but still a tad rich 

42.5 is much better and gives a good plug colour with most riders 

40 is too lean  

Main Jet: 

Should be 100
