4 Stroke classification

[Race_blue60]

so im just wondering is if anyone else is just sick of listening to people b*!ch and b*!ch and complain about the FX Nytro racing in the 600 class, even though the ISR has its classification for a 4stroke and what specs it has to have to get into the 600 class and how on bigger circuits im competitive and losing.. On our smaller local curcuit you could walk people ...What i say is that in the stock class you have the line as far as rules go that you can go up to, as far as clutching, etc... and if they dont choose to go out and put in the time to get fast like or go as far up to that "line" as we do then theyre not as committed to the sport as much as they should be....but back to the fact, does anyonelse have a little more "tech" aspect of this and how a 4 stroke can be 1050cc 138HP and race in the 600 or how the new skidoo 1200 4tec is 1170cc and pumps out 135 ponies....besides ...(we gotta get a new one sayn "yamaha 4 strokes rule" now too)

I believe ISR is using HP for the classifications.
That said, some local clubs/races still want to base it off of displacement only. Which of course hurts the four strokes big time. I wouldn't want to race my Nytro in the 1000cc 2 stroke class, 138 hp to 170hp not much of a contest there!
There is a snow drag that I like to go to, last I heard they still hadn't updated they're rules to include 4 strokes. I hope they do this year, as I will have a Nytro and would like to race there.
With other brands coming out with 4 strokes also, it should help with getting the 4 strokes classed right at some of the local non-sanctioned events.

yeah thats what i mean.. last year my buddies and i went to a local grass drags with my Phazer obviously in the summer and between summer and winter i picked up my Nytro and went there for their sno drags and of course the people running it have no idea about how a 4 stroker works and besides the other Yamaha fans watching im the ONLY one there dressed in Blue. But yeah they try and want to base it off of displacement so i got kicked out of the 600 class and even though i had 3 guys in mine and my buddies faces lol literally they let me race the 700 and up classes. but thats mainly what people see are the smaller local races, then when i go there for practice and im clutched and w.e else to actually run circuits and theres two strokers there that the people just pull out of the corn crib and say im gonna race then when i walk away from them they dont take into consideration or think about the clutching, gearing, suspension setup asspect of it and just look at it as hes a 1050cc racing in the 600 class or 700 etc...i could go on this allday lol but like i said keyboard racing dont get my sled faster i just wanted to know if anyone else is bothered by this of had similar problems and could shed some light on it...

I think that as 4-strokes gain in popularity, they should only race against 4-strokes of comparable size.
Your not really comparing apples to apples if your racing a 4-stroke against 2-stroke, in my opinion.
Im not a big tech guru, but my understanding is that there is a big difference in the torque curve between the two, hence, apples to oranges!

This is just my opinion, dont hate me!!

Then make a 2 stroke have the same torque curve...... The 4 strokes also have the weight dis-advantage. I think they have them figured out what class they should be in. The F7 still wins in the 700 and most of the 8 classes. It's 5 years old. So does the F6..... No one else seems to dethrone them as of yet.....

How??
How about making your 1000cc 4 stroke have the same HP as a 1000cc 2 stroke?
The fact is, they're different!
If your 140 horse 4-stroker is beat'n up on 140 horse 2-strokers, why would you want to race against them. Do you really feel that your a clutching and tuning God? Or could you possibly entertain the thought that it has something to do with the inherrent differences between the two?
If I have an unfair advantage over someone, I really wouldn't be that proud of beatting them.
Im not trying to start a big bashing debate here, but Im open minded enough to understand why they complain.

everyone in say a stock calss has the same "line" as far as clutching and w.e magic you wanna do to your sled that you can go up to the point while still being stock, weather ur four stoke or two stoke you have the same rules ...if you choose to go say to a step 5 out of 10 under the rules and the other guy wants to put in the time and money and know how into his sled to go to the step 10 out of 10 still within the rules but hes actually taking his sled all the way to that "line" i talked about... thats his choice i mean like when i went out to haydays and got walked on in the 800 class di not even make the heat , the 700 class all these are trail stock by the way, didnt make it... 600 class took a 3rd and a 2nd...its all a game about putting the time, know how, money, and committment into the sled, but the people on 2 stokers dont look at that part of it like i said they just look at it as hey hes on a 1050cc yamaha racing against my 600cc t wo stroke sled

What!!!!! What are tring to say, because you make no sense. When did I mention I was a clutching god?

You want unfair... Try this... Go to a local drag event, only to find out that you are racing the same guys that just raced in the World series of ice drags and he and his winning sled is in the amatuer stock classes and they allow it. That's unfair....

Sorry, the "God" comment was more directed at the other posts not yours .
But the 4 stroke making the same HP as a 2 stroke was.

 

[SledFreak]

CC for CC, they sometimes can and sometimes don't make the same hp... A 1000 2 stroke makes more hp (F1000), then a 1000 4 stroke (Apex). A 600 can make the same hp as a 1000 4 stroke (Nytro). It all depends how they built them I guess. The Nytro is classified as 130hp. Most 600's are 128+hp. I guess if you compare strictly hp classification, then yes, the 4 stroke maybe quicker, but, it also has the weight disadvantage.

I'll make a comment as someone who has spent a lot of time and energy towards the development of a snowmobile drag race track facility and races.

We make every effort to assign sleds to the proper classes, based on what appears to be accepted practice in North America. We make every effort to ensure that sleds entering the stock sled classes conform to the rules. We also make every effort to ensure that the sleds entering the improved, and pro stock classes conform to the rules.

We have caught people trying to bend the rules, and no doubt have missed others who have been successful in not getting caught bending the rules. This is just the way things go in racing circuits.

I've noticed when it comes to the stock classes, from time to time a manufacturer comes out with a stock sled that dominates a class. You can't expect the four manufacturers to produce identical sleds.

I've also noticed that there is a small percentage of racers that you can not please no matter what the issue is.
