I have had my kart for a few months now and have a run a good amount of practice laps at this point. Been really focusing on the basics, using all the track, minimizing sliding, maximize braking, etc. Still probably not super consistent but feeling much more capable. I have noticed I’m usually able to keep up with other guys in the turns.
But I am left dumbfounded as to why I am losing so much speed on the straights. My lap times are about 2 whole seconds off the pace. At first I thought it was just me driving improperly. So I focused on getting on the gas sooner, assuming I wasn’t getting enough momentum off the corners. This didn’t seem to help much. It also feels like I just have less grip than other guys (had my rear tires around 9-10psi). I have two seat struts, HH axle (I was told this is the best axle for the track), and I am running the neutral setup up front.
The other thing is that I am around 5800-5900 RPM at the end of the straight. I didn’t want to immediately change gearing, as I thought I might just be driving wrong. A radar gun showed my speed at 54 mph and everyone else at 52 mph at the end of the straight. Also note I was told the kart was all setup for the track (the track sold me the kart, so here I am thinking this is just hop in and go fast). Last owner seemed to always win with it (believe he is/was with the RPG team).
So all that said, any ideas to get me more up to speed? Will a gear change make up 2 seconds? Do I need a carb adjustment? Where can I find more grip? Just a little frustrating having a great kart but everything seems off.
Thanks for any thoughts/input.
