Senior/Heavy Shifter
Pro125Kid Kart, 50 Comer per WKA rules, no exceptions of any kind. Gearing and exhaust would be per WKA rule book. The reports of $1500 kid kart motors are urban myth. The top builders will blueprint them for $350 or less. And there is no need to blueprint them for the first year until the kid gets some driving experience. When you go to sell it, you can sell it anywhere in the country. I don?t see a down side here.
Junior 1. Briggs animal only per WKA rules including weight and restrictor. Its time to slow them down, lap times under 1 minute at IMI are TOO fast. For all practical purposes, this class last year was all animal so since the market has spoken, why not formalize it? By adopting the WKA rules across the board, the racer can buy a package from dozens of different builders and race any where in the country they wish. The engine package is relatively easy to tech as you have clearly defined rules and procedures for tech.
Tag Baby. This is where we dump the younger tag karts. I fully understand the attraction of karts like the Mini-max. One of the larger expenses in karting is all the other stuff you need to run a particular package like jets, clutch sprockets and the like. A package like the Mini-max greatly reduces these costs over the life span of the karter as the spares and stuff carry forward. Tag USA/SKUSA rules, no exceptions.
Tag Junior. Tag USA rules including restrictors, no exceptions. No more adult motors in Tag Junior.
Tag Senior and Tag Masters. Tag USA/SKUSA rules, no exceptions. Tech should honor the seal for those engine packages that are sealed. However, you can develop tech procedures that can check most of the performance enhancing parameters without breaking the seal. For example, you can check head volume, squish, reed cage and reed material, stroke and porting without breaking the seal. With a bore scope, dial indicator, solder, dial calipers and a burette, you can check all these items in less than 15 minutes. The only items that need to be removed are the spark plug, pipe and carburetor. Anything outside the seal is of course subject to full tech under Tag USA rules.
Senior 4 cycle. These guys did a great job of bringing a class back from the dead and deserve a place to play. Last years rules seemed to work, why change.
K3, Novice Shifter. This class is growing and deserves a place. As dad?s find that the costs are actually quite low, they are jumping into it. It has many of the same advantages as mini-Max. Your spares and tuning will carry forward as you move up. SKUSA rules
K2, Junior 80. A good strong class, minimal changes. SKUSA rules, no exceptions this year including ignitions. In other words, PI?s would be in.
Novice Shifter. A good class last year. Same rules this year, no changes at all. Top 5 in CSC points must move up to Pro.
Stock moto. SKUSA rules, open to any driver. Weight to be 385#. This class would be in place of S2. S2 was not well represented last year and does not deserve to continue. However, if a stock moto class were offered, there would be many experienced racers who would jump into it as the costs would be much lower than any shifter class. It just might be the class that saves shifter racing from itself.
Senior/Heavy shifter. Same rules as last year, no changes but might consider giving the motos a weight break.
Pro 125. Same as last year, no changes but might consider giving the motos a weight break.
Some thoughts on tech. If we are going to get serious about tech, we need a spec fuel. There is too much to be gained by juicing fuel. To cheat as much in the motor as to get what you can gain in the fuel would be so easy to catch, you wouldn?t even need to tear them down. Its low hanging fruit and in my opinion, engine tech is just punitive costs for winning if you?re not going to spec fuel. Run what ever fuel you want for club races, but CSC races should be run with spec fuel and procedures developed to check it.
Tires should not only be marked but also checked for correct compound. Last year, only once did tech check my tires for compound (Steamboat) and at no time did anyone check durometer. You can gain up to a full second at most tracks by doping tires. Let?s put a stop to it.
In these two areas, a person could cheat and gain seconds and we don?t tech them. Yet they are easy to catch and simple to tech. We tear apart motors which are difficult at times to tech and where gains are minimal and expensive to put back together. And even there, I?ve never seen us check head volume, bore and stroke and that is where the power is in the 2 cycles. We tear them apart, miss all the important stuff and then complain about the bearings, gaskets and seals that have minimal impact on performance.

You said it , I didn’t!!! 😀 😀
It is impossiple to tech a “stock” ICC from a built ICC in several cases. While most Pavesi and TM engines are not ported at the factory, most of the other ICC engines are ported. For example, we ran stock CRS ICC engines and they ran with the best of the built ICC engines. They were ported at the factory. No stock moto would come any where near running with them. For practical purposes, there is no such thing and no way to tech an ICC engine for stock. Stock moto, mild moto, or what ever you want to call it, can not run competitively with any stock ICC and should be run seperately.
The best and simplest thing to do would be to pick a set of rules, WKA, IKF, KART and tech per those rules.
Larry, many of your observations are very well founded. Karting has struggled with these issues since its inception. One of the biggest reasons is there is very little money to be made in karting and everyone is fighting and clawing for every dime they can get.
As far as where to start, I could type for hours and still not answer all your questions. I suggest that you call me at the shop when you have time and I would gladly answer any questions. I do not sell karts, I manufacture parts that fit in just about all karts. My sons have raced in Colorado for over 8 years and we have raced every class from Junior 1 Briggs flat head to Tag to Pro125 shifters.

I was talking today with a guy in CA who runs in the stock moto class. They let theirs open to any driver, not just novice. Their rules are basically the rules as posted on SKUSA’s web site. It is a rapidly growing class.
But one thing I have wondered as we are in this situation. Where does a good driver go if they can’t play in the top class? We can’t afford to play in the Pro 125 class but both boys could clearly run there competitivly. If they want to run shifters, could they play in a stock or spec class? We could afford that. Is it Pro or nothing?
I have had some guys tell me we shouldn’t be in the Tag class, it’s a novice class. Where should we be? If you reach a certain skill level but can’t afford the level where others with your skill level are playing, are you supposed to quit?
If you run the stock #40 slide, run a 35 outer pilot and a 35 pilot emulsion tube. and either 155 or 158 main jet. If you run the #45 slide, then go to either 38/38 or 40/40 on the pilot jets. The #45 slide will greatly improve the bottom end power with no impact on top end power. You will run the same main jets with either slide.
I would get which ever set of pilot jets you need for the slide you have and 152, 155 and 158 main jets. We have only used the 155 and 158 mains so far this year.
Depends on how fast you roll the trailer. I have been using a different route the last few times there and its workd great. I taek I70 to Limon, then south on 287 through Lamar and Springfield, then straight across OK, then around OK city on the south west. It brings you in just south of the track and is about 2-3 hours less time on the road when compared to the taking the freeways through Kansas and a 100 miles shorter.
The roads are 2 lane but there’s no one out there and the roads are in very good shape. There’s cheap gas in Springfield. Don’t fill in either Limon or Lamar. The only traffic out there is heavy trucks and they are rollen! Don’t get in their way.
As you are coming into town, you will see an exit for Mt Werner road. Take that exit, turn right on Mt Werner Road. At the first light (less than a 1/4 mile), turn right and the track is on the left.
Angie, when they get “old”, they have a hard time remembering what they did and when but they know they did it better!
It will be the same basic schedule as last year with 3 rounds Saturday morn for practice, qualifying in the afternoon. Sunday starts with one 5 min. warm up with prifinals before lunch, mains after lunch. Hope to be done and out of there by 4:30/5:00. This way everyone gets home at a resonable hour.
