Set Up Advice

 

Rotax Max Light:

17 tooth front sprocket, selection of rear sprockets from 73 to 76 teeth.

Jetting:

Non evo rotax engine -98 needle

Evo rotax engine - 57 needle.

160-168 main jet with heavy floats. Expect to see speeds of 150km/hr.

 Rotax Max Heavy:

17 tooth front sprocket, selection of rear sprockets from 74 to 78 teeth.

Jetting:

Non evo rotax engine -98 needle

Evo rotax engine - 57 needle.

160-168 main jet with heavy floats. Expect to see speeds of 150km/hr.

 KZ2:

1.10 ratio gearing will get you in the ballpark. Jet up richer than you use on a sprint track. You want to be providing the engine with plenty of fuel when you come off the throttle at the end of the straights. Go richer on the pilot and idle circuits. Expect to see speeds of around 180km/hr.

Some driver feedback:

Julian Osborne 19front, 21 rear. I tried 19front 20 rear but it was definitely too tall. Main jet depends on needle tip. I run 158-165 with a k8 needle (1.5mm tip) if you're going to run k98, k22, k21 etc you will need much bigger main jets. Also make sure you have a 300 needle valve, this is essential. If you have a 250 it will lean out down the straights and seize

Darren Maguire If your mid island John Wallace from karts and parts Ltd, other wise Danny from paffoni had 21 rears and I guess he can sort you for fronts. With jetting as Julian said it sorta depends but with Peter dicks , Cameron dance, Julian showing kzs work on the road . Just be sensible with your jetting. I think the k23 and 98 needles will be in that 175- 185 ranges ( after talking to Cameron and peter) I personally have used the k8/3 needles with no issues at around the 155-165 range but you definatley need a good size needle valve, 300 + or it won't matter what size main you run
 
Darren Maguire And possibly to be safe run a good oil at 5%. some may say that is to much but it's cheap insurance. Seems to work if you want to look after you gear
