Most modern karts will have a third axle bearing, this bearing is located on the inside rail where the motor mounts and can be used to adjust rear grip on the kart. Kid Karts and Cadet Karts will not have this bearing, some older frames may not have it either.
Setup Tip: My kart lacks rear grip
On a track that has low grip or in low grip conditions, loosening this center bearing can help you recover some of that grip. It is advisable to remove these bolts instead of just leaving them loose, this will help prevent a bolt from backing out and striking the sprocket hub. Take tie wraps and insert them through the holes, secure them lightly so they will not break as the chassis tweaks in a corner.
At HCKC this may help you regain some grip in colder conditions.
If you would like a close seat on the racing action, and a free one as well, we welcome anyone who wishes to volunteer. Corner Workers have the best seat in the house, on race day HCKC can use up to three in the outfield. Pit-passes are free for volunteer corner workers, and you do not need to be a member to help out, anyone who is willing to help is welcome. Please show up around an hour early and ask for the Race Director, so we can show you some of the basics - flags, radio operation, etc.
