Hi there, ladies and gents. I recently picked up my first kart, an '05 TK Krypton 125cc shifter. I know, I know… shoulda started in an LO206… but please hear me out here.
I’m not new to racing or driving extremely high performance vehicles in hill climbs, road courses and autocrosses, and I have enough experience to know to take it easy as I learn the machine. I have no delusions of going out and winning any races against any karters and fully understand that if I tried to hang with the fast guys, I may very well get hurt or hurt someone else in the process. Additionally, because the local racing org couldn’t manage to negotiate their contract with the only kart track in the state, it looks like wheel to wheel action is dead in the water until they figure something else out. And so, I turn to autocross.
I’ve had the kart out a few times in the parking lot at my work, which is pretty smooth and bump free, but still managed to grind the frame at the front and just behind the waist. I had an experienced karter look at it and he said it’s not a concern all things considered, but advised to gain clearance and/or add some skid plates so it doesn’t get worse. I have some skid plates on the way and moved both shims above the spindle. He also suggested possibly running more tire pressure or a slightly taller tire up front. The kart currently has MG HZ (not HZ-i) tires on it, and since a 40- 50 second autox course won’t give me any time to build heat in the tires, I have a set of MG YZs on the way.
But his comment about a taller tire got me thinking… What about running rears on the front as well? It’d give me an additional half inch of clearance up front. I test fit one of the spare rears I have and it does clear the caliper and produces a 53" width measured from the outside edge of the wheel (the rear is 55").
What are your thoughts on running rears up front? Keep in mind, I’m not bound by any club or sanctioning body rules regarding tires and my competition will not be wheel to wheel. I’m not even worried about getting FTD; I really just want to go out and have some fun without destroying the kart in the process. Can you think of any harm or grossly increased wear that’d be incurred with this setup? If not, is there any advice on caster/camber/Ackerman that I should take? I did google this subject with no luck prior to coming here and posting but if I missed something and this has already been covered, I would greatly appreciate a link pointing me in the right direction.
Thanks, and I look forward to learning from you all and being a part of this community.
