As a follow up to September’s article on Quick Change Caster, hopefully you have put the Quick Change Caster Set Up on your kart and are now wondering when and why you would use it.  If your kart has adjustable caster pills and for some reason you have not have put this set-up on, I highly recommend doing so, it will change the way you tune with caster.  To be more specific, since the base caster for any given chassis is set at the factory and changing it in the traditional sense was always a big time consuming task, I never experimented with caster.  Now I try a caster change almost everywhere I go. So let’s break down what caster does and why you would use it…

This may be my most controversial article.  Why?  Because if you go to any kart shop, go online, or talk to people at the track, they will have conflicting views on how to tune with axles.  Some will tell you that if you want to reduce rear grip, you have to soften the axle.  Others will tell you, quite categorically, that the only way to reduce rear grip is to stiffen the axle.  So who is right? Funnily enough, depending on which chassis you run, they could both be right.

I will give you a perfect example of how this is possible.  In the Tony Kart chassis lineup, they have two chassis that share the exact same frame geometry but have different tube thicknesses.  The Racer EVR uses 30mm tube thickness while the Krypton KRX uses 32mm tubing.  I have attached their homologation photos below.  (For those skeptics in the audience, print them up on thin paper, hold them over each other, and yes, it’ the exact same geometry.)  Anyway, if you want to reduce rear grip with the 32mm Krypton chassis, you need to soften the axle.  If you want to reduce the grip with the 30mm Racer chassis, you need to stiffen the axle.

Great, you say, that doesn’t help me at all.  You’re right, it doesn’t, and this is where the websites, shop owners, and fellow drivers end the conversation.  It’s their way or the highway.  So how do you tell which direction to go on the axle, I’ll tell you and the answer is simpler than you would ever imagine…

TonyKart Racer EVR (30mm Chassis) Homologation Drawing.  Same geometry as the chassis below but uses exactly opposite axle change to achieve the same goal!

TonyKart Krypton KRX (32mm Chassis) Homologation Drawing.  Same geometry as the chassis above but uses exactly opposite axle change to achieve the same goal!

While FKI is written primarily for the Sprint Kart racer, I know that some of you may also catch the occasional road race.  I will admit that when I first got into karting I swore that I would only kart on kart tracks.  I used to constantly say that “If you want to race on big car tracks, get a big car.”  Then in 2010, the ProKart series stopped at the Streets of Willow, a 1.6 mile road course with over 100 feet of elevation change.  The “Streets” features a 270 degree “Bowl Turn” with 20 degrees of banking (you could watch karts go through there like they were driving on a wall as you approached the turn), two 100 mph straights, a double right hander that perfectly emulated the long, double right hander (Turn 2) at Magny Cours (one of the best corners in all of Europe) and a blind, flat-out 90 mph kink.  Needless to say, I instantly became a huge fan and immediately erased my stupid “big car, big track” saying from my vocabulary.  But the big question I had going into the weekend was – how do I set my kart up for a road race?  Well, luckily one of my friends road races all the time and gave me the perfect (race winning) set-up which I will now impart to you…

If you have been reading your FKI’s and testing diligently, eventually you will notice certain tuning patterns emerge from your go kart chassis.  Pay attention to these patterns as every go kart has what I will term “tuning relationships” and once you see the pattern, you will dial yourself into any given track condition so much quicker.  Mastering tuning relationships can be the deciding factor between having a top-five go kart or a winning kart.  The quicker you get close to your ideal set-up, the quicker you can experiment with the smaller things to find that last tenth to push you much farther up the grid.  So what exactly am I talking about?  Well let me run you through a couple of examples which should help you determine your kart’s tuning relationships regardless of your chassis type…

Why are there circles drawn on this seat? Read on to find out…

If you have been in go karting long enough, you have definitely heard the claim that you need to use the factory seat in order for your go kart chassis to work properly and be at its optimum.  Most likely you will hear this from a kart shop owner which is interesting because there is no extra financial incentive for him to say this since the seat is usually included in the price of the go kart.  The shop owner could actually make a little more money by convincing you to buy an aftermarket seat.  So why do they claim this?  Is it true?  And what if, like me, you don’t fit properly in the factory seat.  Are you giving up time by installing a more comfortable aftermarket seat in your go kart?  Let’s find out…

If this month’s issue had a theme, it would be “The Great Debates in Karting.”  Thus far we have tackled aftermarket vs. factory wheels and braking or rolling off the throttle for fast corners.  Now we will address one of the oldest debates in karting – using air vs. nitrogen in your tires.  Using Nitrogen in the tires is a tuning trick passed down from big car racing.  The theory is pretty simple, since nitrogen heats up and expands less than air, using nitrogen will decrease the amount of pressure build up in your tires providing you with a more consistent grip level and feel over the course of a long run.  In theory nitrogen should also allow you to start with higher “cold” pressures to attain the same “hot” pressures as you would using air once again helping the consistency of the tire.  But kart tires are much smaller than their big car brethren and kart races are much shorter in duration.  So can you still see a benefit using nitrogen in your kart tires?  Let’s test it and find out…

Can Douglas Low Volume Wheels (left) take on Zanardi’s Factory wheels? Read on to find out…

Wheels matter.  Simple statement I know but if you think that your wheels are simply there to hold your tires in place you are missing a huge tuning opportunity.  I have used aftermarket wheels to change the balance on my karts for years.  But when I borrowed a set of TonyKart’s top-of-the-line cast magnesium rear wheels at the SuperNats a couple of years ago to solve a handling problem, it planted the seed to write about the following question – can an aftermarket wheel compete against the top-of-the-line factory wheel?  Let’s find out…

The Floorpan.  Many of you may look at the floorpan as just a means to keep your feet and gas tank off the tarmac.  As long as all the bolts are snug and it hasn’t been dented from a big off, all is well.  Then, upon closer examination, you may think, “Wait, this is one of the only components tying the left side of the kart to the right.  The middle of the kart has chassis tubing, the rear of the kart has the axle, a bumper, and bumper bar (possibly).  Can I use the floorpan to tune the kart?”  The answer is yes.  How?  I’ll show you…

At the end of the What Does A Good Handling Kart Feel Like article (FKI – March 2012), I cautioned against tuning your kart to handle too well.  What do I mean by that?  Can a kart really be handling too well?  The answer is definitely yes.  In the pursuit of the perfect handling kart it is possible to over-stick the kart to the track.  You hear about this all the time in oval racing when drivers talk about finding speed by removing downforce to “trim” the car at Indy.  The same principle applies, albeit mechanically, to karts.  So what exactly are you looking for to get an indication that you may have over-stuck your kart?  Well, there are a couple of things and maybe the best way to explain them is to site a personal example from a race last year that was actually the impetus for this article…

Continuing on last month’s FKI theme of subtle yet often overlooked tuning tools, I wanted to turn our focus to your kart’s bumpers.  While we have dedicated an entire article to tuning with the new CIK style rear bumpers, I realize there are still a lot of you with older style rear bumpers and their days may be numbered as more clubs mandate CIK bumpers in their rules.  Subsequently, I better get this article out before the old style rear bumper becomes obsolete.  This would also be a good time to incorporate tuning with the front bumper so let’s start there…
