Took the car out for its first serious gokart yesterday to bed / test the new brake set up.
After testing well on the blocks with no jammed pistons, a firm pedal and good retardation I sought out a quiet space and took it for a few 200 - 300 metre or so runs.
Brakes checked out fine, good balance, able to lock up the fronts with an intentionally heavy foot. It certainly drives like a light and very stiff car, was more nimble than expected.
My son was watching events from the sidelines... he asked me when he jumped back in the tow car why I kept leaving black marks on the road as it changed gears and swerving as I was taking off?
I told him I have no idea officer... it must have been somebody else..
