    Craig, with TAG classes disappearing, if u have a Max you are placed in a Max class  if there is no TAG.  Most of the tracks in my area that run Max classes run current Max Challenge rules, even at local level.

    I guess my post wasn’t clear…there is a group of guys here LOCALLY that have the old version Max, quite a few in fact.  Many of these guys are pretty bummed out about the upgrades and the new motor release as they wont be competitive (even with the upgrades) when up against the new evo….and most of these guys like their old Max motors, they’re rock solid and easy to work on….remember, I talking local racing, not strict RMAX rules, so no sealed motors here.

    For a few years we’ve always talked about how the Max had more to give, but the restrictions built in by rotax and their rules made those extra horses illegal….ya know, “run a 28mm slide Mikuni and Nox Box”, or a “30mm VHSH shifter carb with an open filter”, or “run the dd2 cylinder with the dd2 pipe and this size jet and MAN!”, or “…I know a guy that can reprogram the coil with a different ignition curve..”, or “ya know, if you raised the compression, lowered the ports and ran the dd2 coil, you can easy get 31-32 horsepower out of that engine…..” whatever, we’ve all heard it.

    We’ve all heard the talk, but it’s always been illegal and expensive due to the cost of Max parts…well now that there’s a new engine that has new internals along iwth new everything else, the parts for the old Max are going to be worthless if they arent already…I have several Max motors…I have dyno tuned, built max that I paid a bunch for this time last year, I cant get $1500 for it now as a complete package….another guy haggled with me over an micromax package for $700 that had the new style clutch and cylinder and a passport…check out ebay, its loaded with rotax parts…sure MaxSpeed says “run your old engine, it’ll still be legal”, but we all know that wont last.  Their goal is to move units, and ultimately they want all of us to go out and buy a new Evo.

    So, once again, people who want to participate will not be allowed to because they cant or wont buy the new “correct” engine.  My thought was to say ok fine, if you want to race your new evo there’s places to do that….if you have an old max and now with parts being cheap, why not try that 30mm carb with the other filter, or whatever.  The idea was to have a place for people who cant go and run RMAX races anymore, that’s it, not start a new money pit class.

    WHAT IF —

    since Rotax says that the old version Max will continue to be legal to race (for now), what if the old engine is better suited for one circuit compared to another?

    For instance, what if the Evo dominates on horsepower tracks and the old Max looks to have an edge on shorter “parking lot style”, “driver” tracks?  Similar to what SKUSA went thru with the Leopard and the Rotax a couple of years ago which lead to death of rotax in SKUSA..so now, if this were to hold true, would it mean that teams and serious racers would need two rotax engines, the old version Max and the new Evo, to be competitive on all circuits…seeing as how we have seen no on track testing data for the new Evo, we really have no idea how this engine will perform or what gremlins may be lurking in a brand new product…it seems that no one in the World of Karting has a handle on what this new package brings to the grid considering the reactions of the New Zealand and Australian regulating bodies…it’ll be interesting to see how it all shakes out

    you need to figure all that out before you spend a dime on parts…otherwise it’ll most likely happen again and you’ll have wasted your money

    swedetech prepped cylinder @ fastech for around $470 less 10% for the Supernats sale makes that about the best deal I’ve seen…if you want just bare cylinder, no plugs, try partzilla.com for parts, I’ve ordered many times from them with no complaints…99 cylinder is $271.95 from them…that Fastech deal is the best, make sure you mention the 10% off supernats sale to get the discount…its posted at the top of his homepage

    Thanks Eric, Dan and Mr Towles for your interest and replies, we appreciate all of your input.

    Mr Towles — thanks for making the tire issue clear as day for us, I think you are pointing to the same variable that Dan has pointed out in his post, that tires can possibly cause flawed results unless we were to test new tires every session which is not an option for us.  I think you are correct about the only way to truly prove the hypothesis is to run it on a dyno with no values input for weather adjustments, which may be an option depending on schedule and timing.  We could use that dyno run as a control result for the experiment, and at the same time introduce Matthew to what a dyno is and what it does….Thanks Mr T!  See you guys around soon…planning on driving any this weekend?  Bring Corey out, I could use a good humbling experience! ;-)

    Fortunately for me/us, this a 6th grade science project and not a senior engineering thesis, and we’re not testing to prepare for racing, so the research will be what it will be, regardless of whether we see changes or not.  After we’ve gathered the results, if we cannot see noticeable differences in our data collection due to weather conditions, then we can “turn the table” on our hypothesis and question why we didn’t find what we thought we’d find and why we think we were not able to prove our hypothesis, thus bringing about new hypothesis — How much does tire wear effect peak engine rpm and rpm increase?  or more clearly, How does tire temperature effect engine performance?…and on, and on…I guess its more about an introduction to using the traditional scientific method model and seeing what arises from following that lead.

    I realize there are countless variables that could possibly effect our research, however I think that bringing too many variables into the experiment for his first research project might be overwhelming and confusing for him right now.  That’s why we chose weather as the variable — easy information to collect and weather does effect performance in one way or another, or so it’s been written.

    We’re still open to other ideas that may produce a larger range of results, however we’ve got to keep it simple to understand for an 11 yr old.  Again, all comments and responses are welcomed and appreciated.

    And thanks Dan for the kind words of support, I’ll update this thread as we move through our research.  Please share with your wife as you stated, I’d be intreested to know her thoughts and if she has anything additional to suggest that may help us along during the project.

    Thanks again everyone for taking time to comment, much appreciated.

    I agree that the 162 main will suffice for us most of the time without much notice here in FL….fortunately for us we are having somewhat of a cool Fall which can give us an opportunity to test in all kinds of conditions…for example, this saturday it was about 50 degrees in the morning with about 80% humidity–cold and damp for us Floridians.  By Saturday afternoon, the front had past by and the humidity had dropped into the 50% range and the temperature was high 70s – low 80s.  And yes, we’d ultimately like to use the aim software to do just as you suggest — compare peak rpm and rate of rpm increase at different weather conditions….honestly can’t say if track conditions that change with the weather would effect engine performance, maybe someone can chime in on that.

    Dont want to get too complicated or consider too many variables, so as not to confuse him and loose his interest.  My goal is to come up with something that is fun for him and allows him to learn something about two stroke engines in the process.  I may call the guys at AIM after Vegas and see if they have any good ideas.

    I hear ya on the science teacher thing…this is a 10 week research project and he’s 11 years old…I didnt  have the academic disipline at 20 to complete something like this!  School sure has changed since the 70’s.

    classic example of too many chiefs and not enough Indians…the whole shake up with IAME didnt help either, which caught long time IAME distributor and dealer TS Racing in FL off guard and scrambling…seems like there’s a united front now to shut out IAME and stock moto from FL, hence MaxSpeed buying FWT and killing both those birds with the same stone, and then turning around and buying Rok Cup USA to fill the now extinct Formula weekends of the FWT, the weekends that Leopards, X30s and stock motos ran….still seems strange to me that MaxSpeed would buy a series that would promote a competitor’s engine package……all just food for thought…who knows what’s really going on…I’ve heard so many “in the know” rumors lately I dont know what to believe and at this point I really dont care anymore….we’ll just have to wait and see how it all plays out…my opinion — focus on increasing the #s at the local level first, then move on the regional development.

    here’s something that I’ve been wondering out loud about for the past few months, but havent found a solid answer to yet…consider this…..

    motocross, especially amongst youngsters (12 and under), is BOOMING in the state of FL and has been for a number of years.  One track near Tampa regularly draws 500+ entrants for it monthly local series races, most being kids under the age of 15.

    I’ve been wondering, why does MX, with all its known dangers draw so many while karting struggles to keep its head above water in the same state/area.  Would be interested to hear some thoughts on this.

    OGP is right down the road, Alex has worked with my son a few times…problem is they’re so buried in racing right now they wont have time to come up for air until next month…they’re gonna dial it in, just have to wait until next month when some of this racing craziness calms down around here.

    TJ — you have any experience with the OTK 1020mm jrs chassis?  I acquired one for my son and have been looking for a good base set up as you described above.  Appreciate it.

    You can see the rules with pics at gorotax.com, it shows the casting # location in a pic….and it is right behind the oil fill/vent.

    can someone post the RMax rule that requires the newer style (`09+) cylinders…all I can find with regard to “legal” cylinders in the rules speaks to casting #s, cant find anything that addresses year of production….maybe it was an update that I can’t find.  Here’s what I did find in the RMC Rules 2013 Bulletin 1….

    “9.1.5) Cylinder:
    a) Light-alloy-cylinder with GILNISIL-plating. Any re-plating of cylinder is not allowed.
    b) Cylinder with one main exhaust port.
    c) Maximum bore of cylinder = 54,035 mm (measured 10 mm above the exhaust port).
    d) Cylinder has to be marked with the “ROTAX” logo (see pictures below).
    e) 125 Junior MAX: Cylinder without pneumatic timed exhaust valve. Cylinder has to be marked either with identification code 223 999, 223 998 or 223 994

    f) 125 MAX: Cylinder with pneumatic timed exhaust valve. Cylinder has to be marked either identification code 223 997, 223 996 or 223 993

    Awesome  Joe, ya’ll come on!  I heard there’s a track similar to 103rd in Jackson, MS, city owned and free to the public.  Brian you left out Monticello, that’s the one I really want to check out.  I saw FKCS is running there the first week of March, too bad because I’m pretty sure that’s the end of bike week and the Speedway races are the same days….doh!

    some people like going to the same place every time — thats fine…some like to venture out and try as many as possible — thats good too.  Bottom line is anywhere gets “boring” if you frequent it too often.  As a parent, 103rd particularly nice to have in town, easy on the wallet.  we can decide at the spur of the moment on a sunday afternoon to go make some laps, and, if someone breaks, well at least we didnt spend $100 for track time that we didnt get to use.

    I’d like to see the City take a more active role in the maintenance of the track itsself, as it needs some work and its nearly impossible for the club to keep it in top shape with the budget constraints they have.  All that said, they do a good enough job with what they can do and the facility is very user friendly.

    I watched the FKCS racing this past August at 103rd, particularly the shifter class.  The racing was great.  in the final, I got to see two of the best gearbox drivers in the country (Neri and Askew) battle it out at super high speeds with Nick showing the younger Askew “the move” in turn one on the last lap, had everyone on the edge of their seat.  Speed, horsepower, Balls and a drafting partner — thats what 103rd is all about from a racing point of view.

    Used to be back in the 80s and 90s 103rd was a regular stop on all the big karting tours — STARS of Karting, SKUSA, WKA even the CIK World Finals were held there in `86.  I took my son to the Rolex last year and he had on a karting shirt.  There were a few drivers that asked him if he drove, when he told them he was a 103rd local, all of them lit up and talked about racing there in years past.  Best story Ive heard was Danika going thru turn one (end of the 1000′ straight) on the gas, never lifted, lost control and literally launched off the top  of turn one, flew about 40′ through the air, landed and kept going towards the road, the only thing that stopped her was the fence caught her steering wheel as she was going under it.  I’ve seen and done similar, but not that crazy…

     

    Another great 103rd story is the legend of Scott $peed…it was either a SKUSA or STARS race, and he was turning sub :30 lap times.  Thats the track record that has never been even approached, he was driving a heavily modifyed CR125, more like an RS125 his brother says.  Just for reference, Neri and Askew were turning 32s in the stock moto final of the FKCS….

    All that pom pom shaking for the place and we havent been out there in months.   Just got the kid a new chassis and went in on a lease at OKC so hopefully we’ll be inspired to go get some more track time soon…
