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 moneyNovember 19, 2014 at 6:16 am #37327
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 homepageNovember 13, 2014 at 12:42 pm #37021
As a long timer in the sport told me not so long ago, “Hey now, stop making sense, remember this is karting!”November 13, 2014 at 5:47 am #37002
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.November 12, 2014 at 11:58 am #36966
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.November 7, 2014 at 11:12 am #36673
thanks for the info….we’ll try and make the december 13th race.

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.September 19, 2014 at 12:23 pm #34059

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.July 30, 2014 at 6:14 am #31158

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.March 4, 2014 at 6:17 am #23156
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.February 4, 2014 at 3:10 pm #20980
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.January 31, 2014 at 5:43 am #20711
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….
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 993January 4, 2014 at 6:54 am #18940
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!January 3, 2014 at 12:31 pm #18908
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…January 1, 2014 at 6:13 am #18718

your thoughts, Jim?December 31, 2013 at 8:02 am #18696
didnt look like they had the best turn out this year…..at least for the sprint racesDecember 23, 2013 at 6:09 pm #18349

there used to be an engine builder in FL years ago that built motorcycle racing engines. He sat me down one day a long time ago when I was racing MX and explained how jetting and premixed fuel work/burn. Basically, the more oil you run, the less gas there is to burn, so you may think you’re mixture is rich, but actually you’re lean due to less gas in the mix. Something to keep in mind, and we always ran our mx bikes somewhere between 40 and 50 to 1, and they ran really well. WKR, Woody Kyle Racing……December 15, 2013 at 5:39 am #17813
