      Definitely using sandpaper on a flat surface is the best way. Also, make sure to clean off the pads after sanding by using some aerosol “brake clean”. If you don’t, the brake pads will immediately glaze over again. Don’t ask me how I know…. :)

      Dennis, I have the same clearance issues as many CR-125 drivers do when using the stock 15 deg intake manifold. I’ve found that the oval shaped K & N RU-1380 (6″ long) works very well for me. Mike LaGrone saw it installed on my kart at the most recent ProKart Challenge race held at Sonoma. In fact, he raced and pitted with me for that race too :)

      I like the RU-1380 best because it’s a “straight” oval shape, not tapered like the SN-2550. I find that the “straight” oval shape tends to fit the Hegar air filter support that I use the best.

      I also use the Sharkshifter engine mount that allows side-to-side adjustment. I understand that other engine mounts also allow side-to-side adjustment. This allows the engine to be moved to the driver’s right to provide more clearance. Beware though…the engine mount can move the engine to the right side enough to potentially cause clearance issues between the axle sprocket/chain and the center axle bearing support and/or center axle bearing/support hardware. Don’t ask me how I know…. :) I had to change to the Sharkshifter engine mount due to the Sonoma kart track requiring the use of airboxes, which are large and cause even more clearance issues… :(

      Please note that I don’t use the offset engine sprockets shown here which would help:

      Todd,

      Currently the S4 Super Master class (S4 SM) is only a “local option” meaning that it’s being offered at the ProKart Challenge SoCal & Texas series’ as well as LAKC held at CalSpeed kart track in Fontana, CA. I’m not sure if it’s being offered at the Can-Am Challenge/ProKart Challenge in the Pacific Northwest. It is not being offered at the Pro Tour level at this time. Hopefully the class continues to grow and gets large enough to be offered at the Pro Tour, perhaps even the SuperNats. The only way for that to happen is to support it at the local level :)

      The SKUSA spec pipe is required but you can run either a ’99 or ’01 cylinder.

      Here’s the latest SKUSA rulebook:

      Jack,

       

      Thank you for the kind thoughts. I’m fine and fully recovered :)

      The spectator video is the best to see what actually happened. You need to watch it a number of times, in slow motion, by quickly clicking on the play/pause button. You’ll see that #58c got really loose going over the “hump” in the road caused by the cross street crown in the road right at the painted cross walk on the street. He veered right then veered left directly in front of me (basically a “tank slapper”). No one’s fault, simply bad luck with all three of us being in the positions that we were in. My teammate #888z had already drafted past #58c and I was following him through to make the pass going into the 90 degree left hander at the end of the straight.

      Tom,

      Chris is referring to “moto” engines and not KZ’s because he’s referring to dirtbikes.

      Please take your KZ comments to another thread.

      However, to address your comment, KZ’s have dry clutches (except for Pavesi which are primarily used in road racing) so the gearbox doesn’t share fluid with the clutch like a moto engine. In a moto engine, the clutch during its operation wears away the friction plates, however slightly, and that further contaminates the oil. Due to this, the moto oil gets more contaminants vs a KZ thus my, and SwedeTech’s, recommendation to use a proper transmission oil in a moto engine (like Motul Transoil). Also, ATF is more slippery than transmission oils and will change the clutch activation.

      I change mine after every race event. For me this includes one practice day & the race day itself. I use Motul Transoil 10W30. I believe that changing it that frequently is “cheap insurance”…

      I’ve heard the ATF is a little too thin and doesn’t have enough or the right kind of high pressure lubricants to withstand the transmission and clutch.

      My engine builder, SwedeTech, highly recommends the Motul Transoil but doesn’t recommend ATF. They rebuild these engines every day and see the gearbox & clutch internals so I trust their judgement.

      I would highly recommend both a RibTect seat & rib vest as they are designed to work together.

      My personal experience: I totally agree with the above comments about staying out of the kart until you TOTALLY heal.

      I used to use another brand of rib vest and seat and I bruised and cracked ribs constantly and almost quit karting. Once I switched to the RibTect seat & rib vest I no longer have ANY pain or discomfort whatsoever (I sprint race with SKUSA SoCal in S4 shifter). The ONLY disadvantages I find with the RibTect seat is that I can’t adjust the brake bias while driving or push start myself because of how you have to turn your upper body sideways to get in/out of the seat…

      When I switched chassis brands late last year it was recommended that I use the IMAF seat (similar to Tillet), which I did, but continued to use the RibTect rib vest. I ran the IMAF seat at the SuperNats, the ProKart Challenge season through the SpringNats. During the SpringNats I injured my ribs which brought back many bad memories. For the next race I switched back to the RibTect seat and continue to enjoy it and I won’t switch again. Also, I found very little difference in chassis tuning between the two seats other than using one seat strut per side with the RibTect vs two with the IMAF.

      I’ve personally seen Paul Bonilla (a top National ranked TaG driver), Curtis Cooksey (a top National ranked S4 driver), and others etc… have success with the RibTect seat as well.

      The most important thing is to get the best and most comfortable rib vest and seat combination possible. Too loose is the worst, too tight almost as bad. You want to be snug in the seat with no slop.

      Regardless of the brand of seat or rib vest, make sure to use the RibTect seat mounting kit as it’s the best and lowest profile available and will eliminate pressure points, especially for the seat struts where they mount to the seat.

      Capped Entries:
      To provide maximum track time for every participant, we will be capping the amount of competitors per class at 40 or 80 as follows: 40 for S1, S2, S5, KZ2, TaG Master, Junior Max and DD2 Max; 80 for S4, TaG Cadet, TaG Junior and TaG Senior. SKUSA reserves the right to adjust the entry cap per class at any time, based on entry counts and class demand.  The format of limiting entries and classes provides 5 days of virtually non-stop racing action. To quote Steve McQueen, “Racing is life.  Anything that happens before or after is just waiting.” To ensure your spot in this year’s event, enter early or you may miss out.

      So, if David Cole is the “Keymaster”, Rob Howden must be the “Gatekeeper”… :-)

      Troy,

      The SKUSA pre-drilled studs, available only at the track (not the online store), are relatively tall with the seal wire hole at the top of them so the seal wire doesn’t go through the stud, only the nut, so orientation is not an issue.
