HPD moving forward with the CRF250 kart motor

Good points Ken, but remember 4 strokes are are much more reliable, much quieter, and they will never need to be rebuilt. Especially at the track, it will be the perfect race engine and they will all be equal in performance. We will never need an engine builder and or tuner because they will tune themselves. Sort of sounds like ICC's, oh well.

I was just kidding, lighten up. Like I started with we all take this too serious. It just seems like the newest thing is promoted as the best option possible, bigger, better, faster and cheaper. No matter what it is.

No lift shift would be a cool feature if they included it. Will be interesting to see how "creative" people get with the PGM-EFI box even if HPD make it a spec one. My hunch is that the package from HPD is unlikely to come in under 6K, hopefully I'm completely wrong Very Happy

Maybe SKUSA will have a new class called F1 hehe.

Benn, I was kidding!

Chris, what makes you say they might not bother with no-lift shift? Just one more liability do you recon.
when I say "trickery" I'm talking about the maps themselves, not the process of programming the unit. Time will tell if it's better for karting than a carb setup. Maybe they'll spec it with a CRC check, but then there's ways around that too. Mike "Goldenhands Fancyhelmet" Goebel will be all over it I'm sure.

I've already said too much Surprised

Jim, it's been proven, fuel injection is better period. There's no "trickery" there's just man hours too create maps, just like there's man hours to get the jets right.... I would be more worried about traction control...

Just my 2 and 3 cents!

1: It's not something new. It's Been out for over 2 years.

2: It will only be able to run at one or 2 tracks .It is not IKF legal and most our tracks are in the NW.

3: It is not legal on many tracks were it has been in race situations as they caused some serious oiled up crashes,if so reliable why would 2.5 qt OF OIL HIT A CORNER AND TAKE OUT THE WHOLE FIELD. SEVERAL HOSPITOL BOUND. Maybe because it was made to go WAP WAP and not VRRRRRRROOOOM!!! VRRRRRRRRRROOOOM! like a 2 stroke does,well if that's not a problem we don't have any way of dumping that much oil from our 2 stroke, no rod to open up the bottom end.We are not cars,we can only cross a patch of oil about 1 inch wide and still save it,but the oil smear from the 250 was 3 ft wide and very long, no were to go but pile in.Take a look at the rep of this motor as a bike and it was high maintinence fast and competitive,again great for someone who wants a starter and not an ICC shifter with a starter.The only reason other then its got air conditioning, and power window's,so to speak Spencer 5: There is a lot of changes to be made for the class to take off,the funny part( Math)and I suck at spelling and math,But,we only have 100 racers,150, in the whole state,and we have a new ICC dealer and now a new 4 stroke dealer. Seams pretty thin to me,so we are fighting to keep our national class alive. SPEC HONDA CR 125 2 STROKE shifter. Hopefully exsplan's all the Jabber from the NW.

6: The Noise..HAHA. HAVE you ever seen a dirt bike 4 stroke hold his throttle wide open for 10 min.Strait?? that is what it sounds like ,its way louder ,and base carries way farther then high pitch .I have 15 teens in my trunk,I don't pimp my ride with tweeters..HA HA .and the bikes let off all through the corner with 1 inch contact patch,well we are pretty much on it compared to that ,more grip and all.
Ever stay in a motel with a club that keeps you up all night ,that is the base ,low tone ,low bellow that keeps you up all night.

7: Guys No lifts were done in 2 strokes and are not legal , keep it simple is why, It Is fun for the holiday rider for sure I love my air con in my car but don't add it to my race car. Spec Honda is as simple as a race motor gets,well if you stay away from outside pretty stuff you don't need.

8: 'O' sorry I had 8 cents to put in, See you guys in Vegas!!!! WOO Hoo, Over 500 spec Honda

Steve, what would be the difference between throwing a rod in a CRF250, and throwing one in a Briggs?

Briggs are legal on probably every track in the country.....

I think the difference is volume of oil.But thats not the only reason.The reason is they just have not been voted into IKF as a class.Till then the track and clubs cant run under there ins.The Briggs motors are all voted in as well,all of them in order to be covered.An ins co has to have a descripion of what they are going to ins.For instance your car,they want to know v8 or 4cylnder.they wont do all cars ,only us cars,untill you apply differently, they just need to know what is what.Like I said there are some ins that have them as an insured class.
