check out the new LO206 specific chassis by TB Kart…they just hit the track here in FL and from the looks and feedback from the new owners, they got it right with this chassis for this engine package, and that came from dyed in the wool 4 stroke guys. Give Miguel a call, they have several new chassis for sale at a very good deal…here’s there FB page, great family of folks tooAugust 26, 2015 at 5:42 pm #53450
Tim’s right, its incredibly expensive to produce anything in Europe due to how much control the labor unions have. That video Tim mentioned — notice how few humans are in the factory, it’s all robots….expensive? Hell yes!! But, OTK Group aren’t stupid, they did the fisability study and saw that human labor is more expensive than machine labor…thats a huge statement in my opinion, and means less jobs and more expense for he consumer…the economic situation in the EU doesn’t help us either, the tariffs paid for each unit exported is ridiculous…..So, if you want a new chassis, get out the check book and get ready to stroke a good one….FYI — Average cost of an mx bike (4 stroke) is nearing $10k these days….its motorsports, its costly, and if you want to be up front, that check book better be real fat!July 22, 2015 at 5:25 am #51706
Rok GP, not Rok TT….otk chassis will get you lots of tuning advice in FL, CRG, not so much…rotax is in a very turbulent transitional period right now transitioning from the 15+ yr old Max engine to the new EVO motor, and the x30, although its been around for a number of years now, it still hasnt seemed to really grab hold of any market share in FL……as far as TAG racing, I hope you’re not too far from OGP, they’re about the only ones left that allow all brands to run together, everything else is exclusive spec engine classes and series….Good luck….July 13, 2015 at 12:34 pm #51352
thanks TJ….I’d really like to put him in a 30mm chassis, but I’m trying to work with what I have (a 32mm krypton) and considering he’ll be learning to drive a gearbox kart <not competing> with this set up, I figured we’d give it a try…ya know, you’re the second person to mention seat struts, however I dont run any on my evrr with a T9.5 seat and the thing handles unreal, must have to do with driver weight I suppose….I know shifters should be stiffer than tag set ups, I have the struts, I guess we could mount them and test attached and unattached to see what works better…if he takes a liking to the gearbox, we’ll sell the TAG chassis and this 32mm and get him a newer (
14 or15) 30mm chassis….or at least thats my thinking….I think seat position is going to be crucial hereJune 15, 2015 at 3:05 pm #49894

yes you’re right, the seat strut is definitely not gonna work after looking closer…I’d bet it mounts to that chassis rail under that runs under the axle….as I understand, the chassis was never homologated and was only available in Canada…but I promise ya, the guy was flyin around Orlando circuit on it.April 24, 2015 at 5:12 am #46747
This is the CRG 4 stroke specific chassis…notice the frame design and seat strut. I saw a PSL backed driver pilot this chassis with the 206 at the FWT 2014 at Orlando, known as a “drivers track”. Howd he do? he lapped the field in every race.April 23, 2015 at 8:00 am #46684
do I hear $450?……April 23, 2015 at 7:30 am #46678
Steen — they use the same gasket and PV housing, so the hole is still there..we put one on as an upgrade, so I assumed it still had some pressure activation, but you’re right, the new PV is controled by an electronic solenoid, so not really sure…April 23, 2015 at 5:45 am #46669
there are several issues that cause the ecu to limit at 12500…see if you can download the manual and it will guide you through a bunch of trouble shooting…I’d almost bet money that you have the gasket between the cylinder and powervalve housing on upside down…theres a hole in the gasket that has to align with the hole in the housing and the cylinder, that’s the pressure feed for the power valve…if its blocked off, the power valve wont work and you’ll limit at 12500…the new power valve has a ground wire thats attached or unattached to change the rpms at where it opens, might want to chase that also…easy to check the PV gasket though and rule that out hopefullyApril 22, 2015 at 11:14 am #46612
seems the birels work well…they’re in the promo video on the briggs site racing
I know of someone here in FL that runs the one of the newer kosmics
from what I’ve heard and seen, the CRG 4 stroke chassis is very good and the arrow AX9 4S is also a good one
Victory Kart also makes a good chassis for the 206April 22, 2015 at 10:28 am #46603
Thanks Mr T, I was really hoping you’d see this post….I’ll pm you my phone # and you can call me about where you’re at over at the Beach. …always wondered why there were not many if any 4 stroke sprint chassis at the track….think I found out why….and true, if anybody knows kosmics and Briggs, its you….how’s Corey’s wrists coming along?
And appreciate the offer once again Gary, I’ll pm you with some details of what I’ve got and where I’m at….I think you hear the frustration, and it’s an ego killer to just quit a project for me…but like you said, might be where I’m at, so quit the whine and cheese party and move on.April 22, 2015 at 8:03 am #46583
Exactly Steve, how much will that chassis be worth after you’ve cut on it? Right now the kosmic I have has some value, albeit not a bunch, but it would be worthless if I started cutting and grinding on it…dont want to do that, and damn sure don’t want to put more $ into an almost 10 yr old chassis.April 22, 2015 at 7:51 am #46581
actually Jimbo, we did talk at length when I was considering getting into this ;-)…as for the mount, again, according to the article on this website about the 16 things LO206 owners need to know, it clearly says more than 3/4″ offset motor is no good…how do you just blow off the manufacturer’s warnings?
As for the chassis, you’re right, we’re not “striving for the best of the best.” If we were, I wouldn’t be posting this, I wouldve just bought a chassis built for this type of power plant, but I dont have that kind of expendable budget and have other family needs that are higher on the priority list than a 4 stroke specific chassis. We’re just chasing some good memories not championships and trophies, and trying to use what we have…..I thought that’s what this program was all about — getting those old karts out of mothballs and back to the track, not being, “the best of the best.”….guess I was wrong….April 22, 2015 at 7:28 am #46579
Gary, I appreciate you’re willingness to help, however between the 4 motor mounts I have — a burris, a mega mount, an expensive odenthal and a cheap aluminum one off of ebay — and the three clutches I have — a Noram, a Max Torque and a Premier– nothing will align properly….with the clutch inboard the third bearing carrier is in the way and I dont want to start cutting off chassis pieces. With the clutch outboard the chain rubs the drivers right seat strut, BAD….damned no matter what I try…..I’ve thrown too much $$$ at this project already, I think it’s just time to retire it and move on….let it be some else’s headache….anybody looking for a 206?April 22, 2015 at 6:26 am #46570
and hey Jimbo — I have one of your motors I was hoping to run, I’ve heard you do a nice job of setting them up and getting them competitiveApril 22, 2015 at 5:54 am #46567
Ha, really? So you think I’m an industry insider who’s posted this as an attempt to throw a wrench in a nationally growing program….wow…..Well, I’m not, in fact I’m far from it. Matter of fact, Jimbo, you and I talked at length when I was first considering getting into the 4 stroke thing.
We’re not chasing any championships, in fact we’ve (my son and I) never entered an event. We’re just some regular people who got into karting a few years ago when I decided I couldnt ride mx anymore and was looking for something to fill the speed fix that mx provided me…..with a public park/sprint track in our home town, we thought it made sense so we decided to give it a try.
The first kart I bought was an old CRG cadet with a 2002 mini max on it for my son, so we stepped in using the 2 stroke engine that was available to us, and it served us well…now he’s too big for cadet chassis at 12 and needs a full sized roller. I picked up a friends old chassis (the kosmic mentioned in the first post) about 18 months ago thinking I could use it for my son when he was ready, hoping that he’d still be interested and we’d still be going driving by that time.
We never have been able to dedicate enough time to driving, so its strictly been a hobby for both of us over the past few years, and I thought the 206 would be a good transition for him moving from mini max into a full sized chassis. I’m not downing the program, I’m pointing out that I made the mistake of believing that it (putting one of these engines on a sprint chassis) was just “that” easy, and it’s definitely not, and it takes some serious research or it will cost you, just like anything in karting….a few of you have mentioned cutting and removing or replacing certain parts of the chassis….that’s would ruin any value the chassis has, and I’m not gonna throw money at modifying a nearly 10 yr old chassis, that makes no sense.
I’ve spoken with a few chassis tuners who have worked with these engines on sprint chassis and they’ve all told me the same thing — “…Sprint kart chassis were never designed to carry those types of engines. If you start cutting and moving things, you’ll change the handling characteristics of the kart. If you want to run a 206, its best to buy a chassis that is designed for it, that way the balance of weight from right to left will be more consistent. And I can assure you(as one tuner told me), there’s no chassis designer/engineer at OTK that’s thinking about a Briggs 206 on the chassis they’re designing.” That comes straight from the mouths of respected tuners who’s names I’ll leave out of this since they need not be dragged into it. And thinking about it, I recall watching the FWT last year at Orlando and seeing a PSL backed CRG kart walking away from the field in Briggs 206 class, looked like he had the entire field out gunned…turned out he was running a CRG chassis made specifically for the 206…that’s a drivers track, and the chassis really shined against the field there.
As for offset, Briggs states that if the engine is offset more than 3/4″, it increases vibration in the head by as much or more than 20%, putting excessive, premature wear on the engine. That’s straight from Briggs, not me. Had a guy from KartSport in Mooresville tell me that they use the burris jackshaft mount on the arrow sprint chassis, but they really try to steer customers towards the arrow 4s chassis that’s designed for a 4 stroke engine…I’m pretty sure they know their stuff when it comes to the LO206 program, and I’m not about to buy a new chassis to make this “work.”
I hold no grudges, just hate that I’m this deeply invested and have realistically made no progress. I was ready to throw wrenches the other night, turned around to take a deep breath and calm down, looked up, and there was that mini max sitting on the shelf staring at me. Then I realized — I could have that thing on this chassis and ready to go in Jr form in about 30 minutes, what am I doing here?!….true storyApril 21, 2015 at 12:38 pm #46516
I was beginning to think I was the only one, Dan. Thanks for the response, lots of adversity in 2 stroke racing right now, but we’ll be sticking with what we’ve got rather than getting in too deep with this B&S thing….somewhere, Rube Goldberg is smiling…March 26, 2015 at 7:18 am #44872
No one is mentioning lap times from their testing….are you any faster with the upgrades?March 20, 2015 at 5:16 pm #44521
Would also consider trades for shifter chassis.March 12, 2015 at 12:12 pm #43927
thanks guys….been looking for a video of a bump start, pretty sure I know what that is, just not sure if he’s physically strong enough to pull in the clutch, run and jump in while dumping the clutch….and yeah, $650 for a starter is a chunk…but then again Dr bills can add up to that quickly…February 26, 2015 at 6:40 am #43058
Jim, whats this crazy otk talk coming from a CRG guy?!January 23, 2015 at 5:12 am #40926
sorry, it is soldDecember 19, 2014 at 2:20 pm #39165
yes. I sent you a PMDecember 18, 2014 at 3:21 am #39084
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.
