We have at least four Jr1 Parents over here that are expressing interest in starting a steady Jr1 Clone Class next season. I'd like to hear from you guys and see what you have to say.
I was thinking 6.5hp clone on a cadet chassis with a restrictor plate(if neccessary).
The reason for going with a 6.5hp engine is because all the hard work and specs have been done already to govern what is legal and what isn't. We'd be able to easily cross utilize Box Stock Rules with the exception of a restrictor plate.

I am all for standardizing the rules for the Jr group. I know my oldest wants to run clones next year and I have been trying to get whatever the general consensus from the various tracks will be to make hin "legal". He would be a Jr 2 or 3 depending on what we are running. I heard Dixon is going to use a restrictor plate. I thought PC said it wasn't.
I know Duffy said his grandkids were interested and Rich thought Noah might want to run too. So it would be great to have everyone go to Reno to play and have the kids be able to do the same.

Our family has been having an ongoing conversation about erica running a jr1 clone next year, if theres a jr1 class she would be very happy.

I have a grandson that would like to race a JR 1 kart. How about just using a completely stock Blue Harbor Freight engine for this class?
I don't know, maybe the governor could be left as-is to keep the speeds reasonable. The gas tank might also need to be moved for safety reasons.
$100. engine sounds great to me.
Then, for JR 2, just remove the governor?

Out of the box HF with the governor removed is still too fast for Jr 1, maybe not for Junior 2.
Laptimes would easily be more than a second quicker than most of the adult clones are seeing now. I know because I have a Junior cadet "Cloner" set up that way and it flat hauls the mail!
It would also be impossible to see any kind of equality in performance running with the governor in place. I think the restrictor plate is going to be the way to go.

BTW - Gas tank relocated to the floorpan is a rule not an option.

Well my son runs a JR1 and an HPV1 and he already blows by the clone drivers. Usually 1.5 seconds faster than a clone on the JR1 Comer and 2.5 faster in the HPV1. I would think the Jr1 Clone with no restricter would be about the same, why use a restricter? The restricter would make it more like a kid kart.

You're forgetting about the difference in weight between Jr 1-2 and adults. A few of the kids who drove my Jr Cloner would regularly outrun both HP1 and Jr 1 Comers, and not with X head drivers either. I honestly don't know how much the restrictors will limit performance but I'm guessing it will not be as drastic as one would think. The folks who came up with sizes for the plates and manufacture them are no strangers to karting (2 or 4 cycle). I would think that their intent would have been to keep the 4 cycle Jr classes somewhere near the performance of their 2 cycle counterpart. I guess the only way to know for sure is to order a couple of plates and test them out. ~Karl

As I understand the rules, Jr1 is the 8-11 yr olds, Jr2 is the slower end of the 12-15yo and Jr3 is an unrestricted clone for the 12-15yo. There is mention of the stock exhaust but I think all the local tracks want to run the "weenie" pipe with whatever current muffler there is. I would love to have a Jr1 class for my 10yo and a Jr2 or 3 for my 12yo. Both fly faster than I do in my clone currently in HPV1 and it would simplify my world to no end to have one set of engine types to deal with (especially these less expensive ones ). Terry |

So the engine package WILL be the 6.5 hp. The restrictor will be dependant on testing against comer times.
NNKC will have a jr2 unrestricted and not a jr3 for the sake of simplicity.
I would like to test a jr1 clone before the end of Oct while the weather is good.
Could any one send me pictures of your jr1 clones? There has been some talk on our side regarding the misproportions of the 6.5 engine on the cadet chassis.
Id like to post pics on our forum to show people that it is fine.

My son raced Kid Kart last year. But moving to HPV1 has been a challenge given the speed differential. I was thinking of getting a clone for his cadet as a transition.
Are the clones, on the cadet chassis, the same times as the HPV1's?

My son Daniel, who has 4 years experience split between JR-1 crappy comer and HPV-1, had an afternoon with the unrestricted cadet kart Karl and Jason build last year and came back into the paddock grinning from ear to ear, mainly because it had much more bottom end grunt than the 2-cycles he had driven for the previous 3 years.
If a Jr-1 clone class is intended for novices, then a restrictor plate is the way to go.
Daniel ages out of JR-1 at the end of this year and I intend to slap a clone motor on his chassis right after the last gold rush to sell that kart, so if we want comparative lap times before I sell it, he's your man to collect data. He's consistent on the local tracks and knows the chassis.

I think I will put one together and see what we get. Is there a Sacramento local place I can pick all the extra parts needed to put the engine together. I am just going to get a Harbor Freight engine.
