I’m new to the page and also new to the karting world I have a predator 212 box stock (non hemi) on a late 80’s early 90’s margay chassi and I’m trying to get my speed up Iv been running on a 1/6th mile I ran a 16/62 Saturday night and as soon as we all took off fell back almost immediately broke the chain right after the flag dropped and when I looked at the tach it read 4600 rpm. Don’t know if my gearing was way off or if it was somthing else in my heat race I had a 16/68 ran decent just didn’t seem to have as much power as everyone else thank you in advance
