WKA 2005 Unlimited Rules

[Randy Domikis]

Michael,

After Laguna and the WSK ICE title, Andys head must be more like 100#'s.......


Randy

[Clark Gaynor Jr]

I don't want Andy or anyone else to have a weight disadvantage when Dad and I get this thing figured out. I want to race on an even playing field. I want to feel like I out drove the competition.

[Clark Gaynor Jr]

I'm with Andy @ 490 lbs

[michael beamer]

I don't want to wear this weight issue out but when you start stating numbers you have to consider their relevance.Most of the nationals you reffered to Randy reflected decimated fields .At VIR for instance Slayor ran the last half of the race alone .This means that most of the shifters were weighing with 1/2 full tanks.This year has not been a good year for this class as most of the races suffered similar occurances,with very few of the 250s still running past 1/2 way.If we are going to look at the weights they need to reflect empty karts without 20LBS of fuel still in the tanks.The 460Lbs is intended to reflect the kart and driver at the end of the race with near empty tanks.The most unfair weight in the unlimited class is requiring the twin 125 clutch karts to weigh 490Lbs when they have shown that they are already at a disadvantage to the 250s.Since I will be running both types next year this weight issue hits me from both directions.

[Andy Kiker]

Michael I am sure you can make 460 with your 250. but if your running twin 125s at 490 wouldn't it make them more competitive if the 250s are at 490 as well?

The weight is 460 for this year (I think), so lets just run the season. collect the data and see what happens. If I start jogging now and don't stop till the start of the season maybe I can get down to Jason's weight.

[Gary Slahor]

Yes......FORTUNATELY the weights are set at 460# for the 2005 season. If they ever go much above this point, I'll honestly have to either buy Jason one of those "lead sled" Anderson Mavericks, or make him quit. I already have 45# of lead pucks bolted to his kart, and much more will become dangerous.

If weight data is taken at the scales this coming season, it will be important to try and get accurate data on the weight of the kart alone.

If they weigh Jason's kart after a race, it will weigh 320#.....BUT 45# of that will be bolted on lead. We need to make sure we're getting a true kart weight, NOT including the balast.

[Andy Kiker]

Gary easy on your choice of words they my be a bit heavier than your karts but led sled. I do see your point thou. There must be a happy medium for everyone. Maybe we should switch drivers put Jason in my kart and me in his.

[Gary Slahor]

Andy,
"Lead sled" migh have been a bit harsh, but it was starting to sound like the Maverick drivers were trying to get the weights raised just because they choose to run a heavy kart. The weight doesn't seem to hurt you too much. BTW- congratulations on the Laguna win, and the WSK championship.

I'm up for a trade. Jason's 1995 worn out, old, non adjustable Anderson, for your brand new Maverick ? Even up ?

As an aside....I'm not sure the weight affects the lap times of the IC/E karts all that much. I've practiced Jason with NO lead bolted on - That would be a racing weight of 415 - 420 #, and couldn't see much (if any) difference on the watch. I know there should be SOME difference, but we've done it several times, I've not seen it.

Based upon may of your suggestions, editorial and clarification changes have been made.

1. 450's will be allowed to be used on an ICE or Laydown style kart.

2. You are allowed to use an axle clutch on a shifty. This was added to the slipper clutch and sprag section.

3. The 250's were always "Stock Appearing", but some had engines that were a mix of different year parts. The intent - is a 250, that is available to everyone, mass produced OEM items. So a Honda 1988 bottom end with a NEW 2004 cylinder is acceptable. So the wording of: Engine is to be stock appearing, interchange of parts between model years allowed - was added.

4. Clarification: For dual engine karts, we allowed 125cc Air or water cooled engines (usually Parillas). We also allowed the older 135cc engines. To make it real simple, they are now ALL classified as 135cc Dual engine. All Stock Appearing, all Open Fuel.

5. ICE karts can be used for 250 single, 450 single - OR dual engine applications; added to be allowed; Any IC/E legal kart (i.e. Anderson/Zip/Swift/Stratos) is eligible for competition in Unlimited 1 & 2 with the appropriate engines. Engine is now EngineS - ie; you can use dual engines, per the chart.

6. 39mm Carb - Size, tech and intent. For the 250's, the intent was always to allow a max size 39mm carb. A problem arose when the tech procedure used by WKA, did not take into consideration non-round or oval carbs that we were using. After some measuring, we decided that the Kehin, DelOrto and Mihuni 39mm MODEL carbs, did not exceed 42mm at any measured point, so we set that for 2004. This was not meant as an opening to modify the venturi of the mass produced 39mm carbs. wording is now: Approved slide valve carbs are Keihin, Mikuni, and Dell'Orto 39mm model carburetors. Carburetor venturi must remain stock. The intent is still the same. You can still use a carb modified for a pump around system. You can add a power jet. You can polish the carb venturi.

As the season progress, you may have a question regarding a part legality, or a new carb becomes available etc - you can ask myself or a NRRC member for clarification. For new parts, engines, componets - this may take some time to get an approval or rejection. So ask before you move forward so we/I can have enough time to take action. Showing up at the track and asking in tech will become YOUR problem. In general, rules for 2005 are now set and generally only safety items are addresed for rule changes. However, this is a class where people like to experiment. We will try to accomodate if possible.

Randy D. has taken upon the task of the weight issue. I am sure we will have more.

If anyone needs a text version or a ms word version, please send me a private e-mail. (or if someone can tell me how to insert an MS WORD doc - that would be fine.)

One last note. For a bunch of guys that seem to have the idea of lets run what you brung that attitude of keeping it a "friendly class" seems to get a bit lost in some of these notes ans their replies. Just an observation.

Regardless of weather or not I want the weights raised, or you want the weights lowered, just look at the averages. Most people are on average about 20 higher than the minimum weight in both single and twins. Some are much lower, and some are alot heavier. This much I can say for sure though, it's alot eaiser to add weight than it is to take it off. Ask J.R. what he had to do to get down to the 462 limit on his car. Anyways, I hope it goes up. Can't wait to see what actually happens

Sorry for the bad spelling and grammer folks, I really gotta start checking those things before I send em.

[CHRIS TAYLOR]

Ok, guys. I am on my third ICE kart in less than five years. My brand new one weighs 305 pounds, there is nothing extra on the kart, the nose and side pods are fiberglass, the wing is carbon and weighs next to nothing. I have a 2003 Yamaha TZ 250 on it. I am 5'9 and weigh anwhere from 180 in the summer to 185 in the winter. so that means with about two gallons of gas in the tank I weigh in at 485-490 and that is the lightest kart I have ever had. All the others were 500 plus. Just my info, not that it makes any difference. The great weight debate has been going on for about two years now....?

[Scott Loewenstine]

There was weight data taken at the WSK race at Road America to the best of my knowledge there wasn't 1 kart that came close to 460...hhmm doesn't that make it obvious the weight is to much...

[Chris Reinhardt]

John, from your posting, is it that the 250's and 450's have to use approved 39mm carbs? I know I'm discussing this to death, and I apologize but I want to be clear and my intent is to see an allowance for a 42mm carb on the 450's.
