    New to karting we got a kart with a rotax 125 and need to know what a good gear ratio for njmp. Looking for tire pressures I have 5in rims on the kart. Any info would be very helpful. Thanks Jessica

    Also where can we get this oil for the fuel mix that njmp wants us to run

    What tire brand/compound?

    Sorry, can’t help with gearing.

    Just put the wheels as wide as they will go, set all for 12 psi and try not to make any sudden moves your first track session. I’d suggest you run RedLine kart oil at 32:1 as you won’t have to worry about going through the tech tent for a while. Don’t know what gear you have on the front but an 85 rear gear would be a start. You sure jumped into the deep end with a Rotax as your first kart. Are you local to Millville? Sometimes I help people at the track, let me know when you’re going. Below are some vendors I have used for Rotax and general kart stuff.

    Thanks gif! Why do you say that I jumped into the deep end? Haha

    i have a 12 front and 76 on the back the highest gear we have is a 83.

    We are trying to get to the track soon! I can’t wait to test it.  We also still have that other kart with the Parilla motor I think all we need is a new betters for the starter for that.

    You’ll find the answer when you hit that sandy patch going into turn one at 90 mph.
