Christian FoxParticipantFound one, thanks
Christian FoxParticipantWhat class were you in? They don’t use the times to “line up” for qualifying, they use them to split the biggest classes into fast and slow groups for qualifying. Last year that was only Jr and Sr. So, unless you are in a group large enough that they will be splitting it up, no need for new tires in the final practice.

Christian FoxParticipantSold, thank you everybody for the interest
Christian FoxParticipantMichael Schorn in Oregon does it. I don’t have his contact info handy, but he is active on Facebook and will respond to messages there.
Christian FoxParticipantIt’s all good Richard! Karting is an absolute blast. You are correct in that is expensive to run at the National level, but it’s important to remember there is really good racing to be had at the club level as well. There are loads of talented drivers that don’t have the budget to race all over the place, but they can still race locally against really good competition.
Christian FoxParticipantAll I was saying was that a race like SuperNats is the pinnacle of the sport (karting) in the US, a weekend school in a formula car is not the pinnacle of car racing. That’s why I don’t think it’s a fair comparison.
What something is “worth” is a very subjective thing. If you think a weekend in a car is “worth” more than a weekend in a kart, great, it’s an easy choice then. Totally cool.
And I wasn’t referring to anyone in particular, but I would bet my net worth a true rookie could not show up and win SuperNats, or any National race for that matter. Speaking of Schumacher, he raced SuperNats a number of times, and despite being a bad ass shifter kart driver and a 7 time F1 champ, he never won.
And yes, to be the best you have to run with the best, but you need a good bit of time racing at the club or regional level to be even remotely competitive at a National level kart race.
Christian FoxParticipantWhy would you compare SuperNats to a Bertil Roos weekend? A more fair comparison would be a club race. You can do an arrive-and-drive kart race in a competitive field at my home track for about $300, including race entry.
Why would anyone who is not a committed, competitive kart racer show up out of the blue to race SuperNats or a WKA event? SuperNats is the most competitive kart race on US soil. A Bertil Roos weekend is, um, not the most competitive car race.
Christian FoxParticipantOn paper the 98L should be quicker with its lower octane, but I’ve run both 98 and C12 in an X30 and I’ve never noticed any difference at all, even with identical carb settings. Both are fine with the motor, and both have higher octane than needed anyway. Just use whichever is easier to get.
Christian FoxParticipantMike and Tony are correct, and to Tony’s point, a thinner gasket/tighter squish will lower your exhaust port and retard timing a bit. Yes, you will get more compression, but with a lower exhaust port, you will be moving the engine’s peak hp to a lower rpm band. So, if anything, tightening the squish in the absence of any other adjustment will give you more bottom and mid and hurt your top end. You should be targeting 15k in a Rok, so you aren’t far off. Just add a tooth on the rear.
Christian FoxParticipantA cadet kart with a 60cc motor (Swift, Rok) weighs around 140lbs, so at 115lbs. you guys will be a fair bit overweight. You can run without kart graphics and save a couple of pounds, but other than that not much you can do.
Christian FoxParticipantDon’t get a shifter kart for your fist kart. You have a lot to learn before you throw shifting gears into the equation. Shifters aren’t the pinnacle, or logical end, to racing karts, they’re just a different discipline. They are really cool, but completely inappropriate for a beginner.

Christian FoxParticipantWhat Greg said. 01″ is double what you would want for an iron bore cylinder, let alone the Nikasil cylinder you have on your TM. The recommended clearance is .07 to .075mm for that motor, or about .0028″. Either way, if your motor stuck, you’ll want to have the cylinder honed before you fit a new piston, so don’t even bother measuring now. To do it right you need a good dial bore gauge and a nice micrometer, or preferably a calibration ring.
Christian FoxParticipantAs of now, the Rok GP is not a well supported engine. I had to prod Rok just to put a general Rok GP manual on their website, up until then, there had never been any documentation available. If you know what you want you can either have Chi Chi at OVRP order it for you, or call:
Jerry White at Kartworkz or Brandon Jenkins at Allison Racing Engines. Jerry’s website has all the relevant parts diagrams/numbers.
No one stocks parts for these things; they are still way too much of a niche engine for anyone to bother. But the above guys can get you the parts drop shipped from the importer. Rok is pushing pretty hard, so maybe parts availability will improve.

Christian FoxParticipantWell, so much for the Canadian trial balloon…Rotax claiming rule US for 2017 starting at US Open this summer.
Christian FoxParticipantRotax claiming is coming folks. ECKC (Canada) just announced a claiming rule for Rotax motors effective this season. I would expect the US to follow suit; Canada is typically used as a trial balloon for Rotax rule changes, and the US usually follows the following year. I believe Canada briefly had a claiming rule at one point back when Lance Stroll’s dad was going bananas on his motor program. It will be interesting to watch. I would expect every single PSL motor built by Dan Lambert to get claimed after the first round of ECKC.
Claiming rules aren’t designed to prevent cheating; that’s what tech is for. They are designed to discourage guys from part matching 20 motors to pick up .2 of a hp.
Christian FoxParticipantTom, the only changes that will have a performance difference are the cylinder and ecu. The current coil, battery box, coil/ecu bracket, and harness will all work with the new cylinder/ecu.
Christian FoxParticipantChris Black is the real deal. We have worked with him for 2 seasons. Builds Championship level motors, is responsive, honest, no BS. Highest recommendation.
Christian FoxParticipantI think there is a series in California that uses them. I love the idea of them. Simple, light, fast motors that will stall and end your race if you do something stupid. That said, I think they are too hardcore for the US. If a series were to bring them in, they’d have to do it differently than they do in Europe. To start, it would have to be one make (karting isn’t big enough in the US for a local shop to support 4 or 5 engine brands) and the motors would have to be “stock”. At the CIK level, the OK motors are open to development and actual engine building. That’s not going to fly on a large scale over here.
That said, it seems that the X30 has stabilized to TaG issue for a while now. SKUSA, WKA, USPKS, F Series have all moved to X30 and people seem quite happy with them.
