Claimer Rule

[brad42]

Last year when the clone class had yet to turn a wheel on a track, we discussed having all of the motors stored in a shed and numbered. At registration you pea pick a number and are handed the corresponding numbered motor. Another possibility is to have someone local stock the ARC clone, and put a tamper proof seal on it.

I am for sure anti-claimer. There HAS to be a better way.

Hi Brad, If you look back at the endless clone thread on the KKC forum, we discussed both those options as well. We also talked about having the track buy the motors and pea pick for each race. I think they are all valid options still.

If you have never read that thread, there is some great history on how we got to where we are now. One of the big misconceptions is that it was meant to be a novice class, that was never the case, for the most part is was a bunch of dads, most with prior racing experience, wanting to get out and have some fun without breaking the bank or taking valuable time away from our kids program. Low budget, low maintenance, high fun value.

The reason I came up with a challenge rule is because nasty pit rumors of claiming an honest person's engine is not fair and just kills the fun for someone just out to race like the rest of us.

I just got done with an NNKC club race and everyone was shocked at the lap times some of our karters pulled today. We saw 58 seconds during practice on a track config that we are used to seeing 1:00 to 1:01.

Immediately i heard cheat this cheat that. Then qualifying times came out and we saw more 58's and 59's from our front and mid pack drivers. One of our slower drivers managed to pull a 58.4 and still didn't finish better than mid pack.

All of a sudden finger pointing stopped and most everyone here today realized this IS a drivers class.

We had a seasoned TAG driver jump in one of my spare karts for the first time today and finish 3rd our of 17.

I'd hate to see any of your seasoned 4cycle drivers not come back to reno because someone keeps claiming his engine. Prove that it is legal and go home with $50 or so in your pocket, plus shut up the finger pointers.

Dan, That was so very well said, I wanted to asee it one more time, You said " wanting to get out and have some fun without breaking the bank or taking valuable time away from our kids program. Low budget, low maintenance, high fun value. " High Value FUN> Yes very well said, Duffy #48, "Coming back stronger for some High Value FUN"..

I'm a little late on this thread.....but, we're new to the Clones, so pls bare with me. I agree
that, for maintaining contol of this class, a "Claimer" rule is probably the best solution. However, I also agree with Rich H. in that the fee needs too be more than $150, but....no more than $200. My suggestion is too let the $150 fee stand for the remainder of this year and be prepared too amend the fee for 2011.

[tommy toro]

I know I'm just a Rookie Newb but it seems to me that theres a bit of a political statement being made here by some folks, As in, Oh theres a claimer rule here so why not claim an engine every race, I get a fast engine for $150 and you get to start all over with a $150 engine that the NFRA has been good enough to supply for you if you choose to do so, fast or turd, We all know its a crap shoot when it comes to clone engines, but why let one person claim all the fast ones? personally I think it's time for some rule modifications.

[brad42]

Agreed on the needed rule modifications. The rules are set in stone for this year, but next year we can change what we want.

My suggested wording is "anyone who elects to claim a motor from a competitor that finished behind him, or has already claimed a motor within the last 5 races shall forever be referred to as "azzhole" or "retard" or any combination of the two words.
