    We had are frist club race in grand jct and the racing was great but the gears for the comers was not not the right gear. That gear was the 78 gear i still belive that each track should have there owen gear.Maybe we can have a vote on this in Grand jct this coming weekend.
    Happy Racing.


    Why do you think it was not the right gear?


    I,m glad to hear that you had a great race. A few questions however regarding what you said about gearing.

    You said that the 78 gear it is not the right gear for GJ, I sincerely want to understand this; by what method are you coming to this conclusion? I fully accept your position and with more information, who knows… maybe I’ll be of the same opinion? So help us out here… by what method have you come to this conclusion?

    Questions: 1. Were you on the big track or the small track? The reason this is important is that it has not been decided which track will be used for the CSC. Sinse the total “track time” for the Kids Karts will be adjusted this year to be more in line with other classes, I personally would rather see 16 laps on a shorter track withen an allotted, (just an example)12 min. time period than 5 laps in 12 min. I think the racing would be better for everybody, driver and spectator. And if we’re on the small track, how would this affect your feelings about the gear?
    2. Do you have reliable mph data from your experience last weekend, if so what is it? We have already determined that our goal is to hold the top speed to 35mph. The mph is the “control” factor not the track, not the length of the track, not the lap times, not the total track time and not even the gear. The gear is one of the methods by which we reach our objective, maximum 35mph. So, what was the data?
    3. You said it was a great race, that’s great! How was the event damaged by the use of the 78 gear, and/or how could the event be enhanced on behalf of the kids if we were to change the gear and what would be the method used to determine the correct gear. Also, how would our “Purpose of Class” as stated at the top of our CSC rules and guidelines be more fulfilled by the change?

    I think if we had more information about what happened we could better appreciate and contimplate your concerns. Thank you in advance for your additional information.

    I still want to know who is driving this gear issue? I think we should vote like we did at I.M.I . regarding this matter for the C.S.C . P.S Scott I don?t know why you have so much animosity towards me personally. All I have tried to do is assist anybody who has needed a helping hand at the track. Please give me a call and lets resolve our issues so we can have a good racing season. 303-961-4301.

    If you are looking for a bad guy I guess I am it.
    There is no conspiracy or anything sinister going on.
    You and I just have different ideas about the purpose of this class.
    I am more concerned about the kids learning to be better drivers than about how fast they can out pace the pack. There is nothing learned when the flag is dropped and by the time the karts get to the end of the first straight away on a long track they are spaced so far apart it looks like 30 minutes into a road race.
    We will evaluate the input from everyone after the race and if there is a more optimum choice I will certainly be open to revising it.

    The spec gear for Grand Junction is 78.

    We will run the short track configuration.
    Time on track will remain the same.

    I don’t have a kid in the battle. But I do think that if you are teching a set gear ratio, it better go along with a max and min. tire roll out too.
    1/2 an inch in circumfrence is a little more than 1 tooth on the rear.
    Just a rim width rule wont prevent some people from growing or shrinking their tires for that little advantage that only their kid needs.
    You also should mention no skip tooth sprockets along with an inspection of the front sprocket for the number and condition of it’s teeth.


    The rules that have been posted for use in the Kid kart class does already include a circumference rule.

    24.4 Tires :The maximum circumference is 33.75″

    Cool, is there a minimum?


    No minimum is listed. However, that would obviously lower your gear ratio and reduce top speed. It’s sort of understood that the spec gear is the smallest sprocket you can run. While the intent is for everyone to run the same gear and thats the scenario here. In reality if someone wanted to run a bigger gear there may not be a real problem. Its unlikely, but not impossible, that with a gear spec’d that a larger gear would produce faster lap times. But, there could be the occasion that parents may want thier children running even slower.

    But, if the child racer is still not ready to run at the speed of others in the class, consideration by parents needs to be made if they are ready for regional level competition. Possibly more practice or local level racing is in order.
