Gearing for Sr champ Predator we have Tried a 18-61 turned only 4678 on both karts this past week we ran a 18-59 4707 and a 18-57 4768 tire pressure 9-10lb
Then your tires were just not in the track enough to generate forward drive to hit better rpms.Kart didnt feel tight it just felt like it was cruising around the track
If I had to pick one target rpm it would be 4850.I will try a 56 next Saturday we both have the Ducar 212cc motors one lap in my kart I turned 4823 but couldn't catch 2nd place kart in heat race went down two teeth and turned 4707 kart felt faster
Ok thank youIf I had to pick one target rpm it would be 4850.
