My letter to the SEB hasn't been written yet, because I don't really know if I am for it, or against it. I suppose that it wouldn't have to be an either/or letter to possibly be useful, but when lines form, I don't want to leave myself in no-mans land Confused

We've been sprintracing for about 7 or 8 years now, all over the southeast, and I've only seen one WF engine in our travels before attending Nationals this year. That WF was not at the sprint track though, a local Dad bought it to run unrestricted in FJB in hopes of keeping up with Jesse in his Comer80.

Another local Dad almost bought one, to replace the Clone so that they could attend the NT's in Dixie and Atlanta, but the closest one (other than the one already autocrossing) we could find, for sale or otherwise, was in South Carolina, having been part of a household move from California, and considered useless for sprint racing out here. Rather than spend the $750 on an engine that came without any support at all, he bought a Raptor from the local kart shop that was much cheaper, but is still being raced on dirt ovals in the area.

Requiring a spec engine is going to eliminate some FJ attendance at the Nationals events, even with a 4 or 5 year phase-in. Most of the current crop of participants are going to keep running what they have, and either graduate to F125/cars before the switch-over, or take a year or two off when it happens and play football instead. Buying a WF to run a couple events isn't going to be in most peoples FJ budget.

If there is an effort to make sure that all new FJ drivers get a WF, starting in 2012, a phase-in will work. But, that means making sure the WF is the overdog engine in both classes.

Having a spec engine will solve at lot of problems at the National level as well. This year in FJB, there was a hub-bub about a Raptor, and in FJA, there was a lot of consternation in the TownHall about our Rotax, and during the event from a few parents and an Op Steward. That could have all be avoided if everyone was running the spec engine, and there was a trained, non-participant, tech person who knew what the engines were supposed to look like inside and out.

I like the low maintenance clutch on the WF, the clutch was my big deterrent from running a KT at Nationals this year, I was a lot more comfortable with the Rotax. The WF clutch isn't the same as the Rotax, I'm not saying that, but it's not based on friction plates that self-destruct the first time you make a mistake in adjustment or power application.

Our local dad doesn't use the electric start on his WF, the cost and trouble of hooking it up is too much for him to be bothered with, but the engine doesn't stall on course either.

The JB version needs a different way to restrict the engine. B&S needs to make a new slide for the carb (assuming it is a slide carb, haven't been that close to one) that restricts the throttle, or put a spacer in the carb to restrict the throttle slide, like Rotax uses for it's MicroMax. Throttle stops outside the carb, bad idea, I've met FJB dads before. They mean well, and their kids can handle it... Laughing

I think that the biggest benefit of a spec engine, being able to significantly lower the minimum weight of both classes.

Most people in Solo are not like me (fortunately I suppose). We sprintrace, and have no problem buying or borrowing (Thanks Rick and Raceway Motorsports) the engines and chassis's that we agree are correct for the classes we race, and for Solo. Most people have one engine, and when they are told it is obsolete, give up on progress and the driver suffers for it.

That brings us back to my initial issue with a spec engine being brought to Solo, convincing new people to run a slower engine against the established teams with KT100's, and convincing the teams without WF engines to buy one for National events.

Anyone can list Pro's and Con's, argue minutia, and generally be negative, optimistic, a politician, or downright difficult for no apparent reason. Solutions are the tricky part.

If I were King of FJ, I would accept the proposal in FasTrack and possibly even be a little disappointed that the phase-in is not 2014 or 2015. But, that would be contingent on my negotiations with B&S Racing (Hey Adam) for them to help us with the proposed transition. Because we'd be spec'ing their engine, I would hope to convince them that it would be worth their investment to provide 10 JB and 10 JA config engines (WF or LO206) to the SCCA to loan to all competitors at National Events (first come, first serve) who do not already have their own WF to run.

A lot of Junior Karter parents aren't able to retrofit a 4cycle to their kart at an event, and that's where having eithe B&S support at the event, or a local kart shop there to provide services and parts (engine mounts, throttle cables, 35 sprockets and chain, etc) would be essential.

If that could be accomplished, it would encourage the "serious" Junior Karter parents to move to WF early, but because they had an opportunity to try it out at their local NT or Pro, they would be more likely to stay with the sport. The less likely to be able to buy a WF would not be excluded from National Events either.

At the end of the Phase-In process, the loaner engines could be sold or donated to the membership, low hours, only driven in a parking lot on Sundays.... Laughing

maybe I should have just written a letter...

Hi Dale, I think this is the perfect letter, could you please send it in so the committee and SEB can share this?

Thank you for the insights and suggestions. It was a pleasure to read. Smile

Feel free to copy/paste it into a letter, I tried twice and ended up submititng empty text boxes...
It would let me fill out my info, but the textboxt was off-limits

I just bought the chassis that Jesse Seeley ran at Nationals with a KT100 mounted to it. It "was" ready to run in FJB and I "had" plans to bring my two kids to Nationals next year. I had to fight with the wife to buy it. There's no way I'm going to be able to convince her that I now have to buy a new engine.

I'm not against a spec engine. However, I believe a future date of requirement would make it much easier to stomach. Say... 2013 or 2014 Nationals?

Why I chose a KT100 for my FJB kart:
1. What I was hearing about the WF and the restrictor in FJB.
2. It was less expensive.
3. 14 out of 23 FJ drivers at Nationals were running KT100s (4/23 for the WF)

Anyone wanna buy a KT100? Oh, yeah, wrong forum to sell it in, right?

Maybe I should write a letter as well.

Now I can't find the request for member feedback on a spec engine for FJ, so I'm going to claim a certain bit of ignorance and hearsay when responding to Robbie.

It's my understanding that the "spec engine" would not be required until 2016, I'm fairly certain that is correct for Regional/Divisional events, and there is also a grace period incorporated for National events. At least I hope I remember it correctly, or the field might only have 3 or 4 drivers next year.

It's not ANY year yet... We're looking for member feedback on the possibility of 2016. Most responses have said "yes" and want to make it happen sooner. As the only one on the KAC with kids involved, both with KT's, I'm in no hurry, but do see some of the value to it.
Write letters, and remember, everything you read is not necessarily brought about by the KAC...we're just a sub-committee.

To echo what Brian said: KAC is just a sub-committee of a "big committee". We cater to the karting related letters from the members, and we bring up what we see as a necessary to keep the competition fair and safe, and sometimes we are advised to look into the rule set by the SEB. I guess we are the House of Representatives, the letters are the constituents, SEB are the senators. We propose the rules based on the constituents and we are forced to modified by the law by the senators or the president. (Why do I feel slimy and corrupted all of a sudden? Rolling Eyes )

All kidding aside, the original proposal was to phase in the spec motor rule by 2016, which is 4-5 years away. (The world might ended up by then, who knows) There are letters and other proposals to move up the time frame earlier because it's so far out. Please remember your letters, whether is for, against, or a simple FYI, would not only help the KAC to propose the right solution, it would also help the SEB to approve or veto the decision. A letter like Dale's is perfect because it would educate the non-karting world folks on what we are really dealing with, rather than "I am not going to pay for another motor". I don't mean this in the negative way because I don't want to pay for something because somebody tells me I need do, I am just suggesting that proposing a solution like Dale's really shows we are working towards solving a problem, and not adding more headaches. JMHO.

Well I know you have my letter because Brian Harmer auto sent me a reply.

My vote was made.

Now waiting for a response so I can get in the right line of motor builders. EitherFJB WF which needs rebuild. orGas Raptor which will need all the tricks done.

Now that it is off season for Flat head oval karts there is a long line for the good builder. Getting a motor back before Dixie NT would be nice.

The link to the latest Fastrack is here:

It kind of looks as though the original topic line of this thread no longer applies to the content of most of the posts, other than the "Out for member comment" issue of a Spec motor for FJ.

About that, I have no real stong feelings one way or the other. All our family's experience in the FJ classes have been with 4-cycle power, not necessarily because of any aversion to the KT-100. It just worked out that way. I really think there should be strong arguments on both sides of the issue filed with the SEB's letter system, but AFAIK, there has been not much said yet in favor of maintaining the current multi-engine structure.

Dale wrote a lot on both sides of the issue, and identified one factor that is certainly notable: The motors used in Kart racing in different parts of the country vary greatly, and what is to be found locally at what many parents would consider a reasonable cost may not match up with what the SCCA feels is proper for National competition in FJ. There is one comment though:
Dale Seeley wrote:

.... That is unfortunately pure speculation. One subject that has indeed been the source of a relatively large number of member comments to the SEB/KAC has been weights in classes. There have been as many in favor of increasing those weights as in favor of reducing them. Kids are all sizes, and there is no easy answer to finding one magical weight that "fits all". Runing "JA Light" and "JA Heavy" classes just is not going to happen. (besides, that would put us back to three letters for the class Wink)

As far as the cost to run a WF motor....
I can't for the life of me understand why anyone would want to do anything other than buy a new one, in the Briggs & Stratton crate, get a motor mount and silencer, put it on a kart, and run it forever. Then, when the family is done with it, sell it to someone else and get a chunk of money back.

We got what turned out to be a Series II motor (new) via an eBay deal some 6 years ago, and put it on a new (also eBay) chassis. It was run one year in both A and B (SCCA restricted) configurations. After that, it was run only unrestricted. In 2009, the last year it was used regularly in the SCCA, it won the Toledo Pro against a KT-100. That year at Nationals it was fast enough for a trophy (2nd fastest raw time on West course) except for cones on best runs each day. And the primary driver was big by then. I forget the weight, but Colin scaled well over the class minimum.
Since I and others can fit in the last seat we put in, the kart has been through several sets of tires, and you know how long the YHC's last on a properly set up kart. The motor was run several times at Pt. Pelee in Ontario, (always with more than one driver) the last one being this past August. It has also been to Beaverun a couple of times. I have no idea how many autocrosses it has run, but I 'd not be surprised if it has well over 500 laps on tracks. Probably more like 600 or 700. A week ago it was run in an autocross style setting with a really long course (fastest run just under 85 seconds) by a dozen college student members of an FSAE team, and half a dozen adults. Driver Weight range 100 to 250#, and the quickest driver weighs around 175#. Total number of runs... 60 or 70? There was nothing left of the tires, but the motor.... No Problem.

Since buying the WF and putting it on the kart, this is the sum total of maintenance:
1. PVL ignition upgrade, to match the newer motors. I did not get the flywheel on tight enough at first, and the motor survived a severe ignition timing issue when it sheared the key at an autocross.
2. Briggs crank- case breather system, took care of a bit of blow-by which showed only on track days a couple of years ago.
3. Carb jet kit, mostly for the pilot jets, which plug up and keep the motor from idling and starting easily.
4. Clutch, an eBay buy so we could have one set up with a different drive gear. We use the stiffest (orange) springs.
5. Several intake to carburetor adaptors, (3?) they fail occasionally.
6. Spark plugs, probably two per year. If the motor misses at high rpm, a plug fixes it.
7. Valve adjustment, once per year, usually.
8. Oil changes, twice to 4 or 5 times per year, depending on use. At 20 oz. per change, cheap insurance.
9. Many, many gallons of premium pump gasoline, a few of 100 octane unleaded.

Gee, that does not seem like much, but that is it. Not bad for such a long-lived motor that has been run really hard every time it is used. I'd love to dyno it and see how much of the original spec'd power it still retains. I don't think it has lost much. We have never once energized the electric starter. The only time I regret not having an onboard battery is when a bad pilot jet makes starting difficult. Most of the time it fires with just a couple of pulls, even if not run for a winter. Frankly, if the motor blows sky high the next time I use it, I'll feel as though I have well gotten my money's worth. And I'll be in line for another one. "FUN to drive" kind of covers it. Great practice motor for the craziness of F125 autocross for me, and it was outstanding for the boys.

The attitude that this motor has to be "blueprinted" in order to be successfully used for SCCA autocross is one that I truly do not understand. Adding 50% to the initial outlay is... not just unneccessary, but pretty much a silly thing to do, good for not much more than a psychological benefit to the parent, not the kid.

For FJB... No one would be happier than me to see a different slide or a slide-based restrictor system developed for the motor. I have never been a fan of the intake device, although at least one person considers it to be "my" unit. Misguided revisionist history. There is an alternative now being investigated, and it cannot come too soon.

As always, YMMV, I'm sure others have had experiences with the WF which were not as good as mine. There are a few caveats to follow if you ever run one, the biggest of which is to avoid depending on or allowing the motor more than an occasionall hit on the rev limiter. At autocrosses, we geared to never limit. That worked. At Beaverun, that setup was painful on some inside corners, and the clutch did not like it. We geared to limit at the start/finish line and lifted when it hit. We were only lapping for fun, afterall. Very Happy
