      Hi,

      I just bought my first kart this last weekend from my local shop after driving rentals for 10 years. This was a pristine used top kart chassis with a rotax engine. The shop mostly deals with CRG, DR kart, gp racing chassis and they are very good at tuning those. However, top kart is new to them.

      So we were looking for a top kart specific tuning guide. Couldnt find it on the web or in the forums here. Anyone have any details?

       

      thanks

      You tune it like any other kart just use the CRG guide.

      Its nice to have one from the manufacture to get a starting point especially. Also to understand how the axles are coded by color etc. Call grand products or top kart USA. One of them will have an answer for you or be able to answer any set up questions you have

      Definitely contact the guys at Grand/Top Kart USA as Mike T. has noted above me, but as a side note those KRacer videos are super good learning tools and explain a ton about chassis setup so those are worth a watch as well.

      The KRacer ideos are great, but currently the links to the videos are inactive.

      I think I have the KRacer videos archived somewhere. Might ask Col if he’ll let me share them.

      I can see the videos fine from the vimeo link in my post. Probably someone fixed it..?

      Caster Top: IN (dot towards front)

      Caster Bottom: 0 eccentric

      Front ride height: big spacer on bottom with the other 3 on top

      Spindle Spacers: 1Big (10mm) 2Small(5mm) inside of Front Wheel Hub

      Axle: Blue

      Rear Hubs: 98mm

      Rear width: 45.5-55 inches

      It would be good to know your weight and height, plus the tires you plan to use.

      LOL, that’s like a 10″ difference, anywhere in there would be good?

      I thought maybe he mis-typed and should be 54.5-55″?  Seems right with Yellows.

      Hi again,

      I got a response from Mike from topkartparts.com link posted above:

       

      START OF RESPONSE ======

      As far as I know, there is not a chassis manual provided by Top Kart and I am pretty sure I would know if there was one. There really isn’t much difference in how you tune a kart regardless of the manufacturer. The difference lies in the fact that different chassis like different rates of lift depending upon the weight, track and track condition. Even different Top Kart chassis like different setups.

       

      What I have found to be most useful is a series of videos done by KRacers in Australia. They can be found at http://vimeo.com/kracer/videos and I suggest starting with the rate of lift video. It may not make total sense to you right away but as you look at the other videos, it will begin to do so.

      ============ END RESPONSE
