Kool.  I like the classes you are bringing in here. 

A few questions . . . . I notice that some of these new engine class rules specifically state that they are only for 4 strokes.  Is it intended that all the twin classes and all the classic classes be limited to 4 strokes only?  If not, will those allowing 2 strokes have a separate set or records for the 2 strokes and the 4 strokes as is done for the existing ECTA and LTA bike classes?   Are all the engine displacement levels open to these new classes (50cc up through 3001+)?

Good luck with this.  Wish I still had my old Honda CL175 . . .

TO clarify, these rulesa are preliminary and subject to change: Like forgetting to add that they are all 4-stroke classes.  (Sorry 2-stroke guys.) They are all open to all current engine sizes.

How would this effect engine designs that were produced prior to 86 but continued on past 86? I.E. the Evolution Harley motor.

Yes, really. Sorry I had a question.

More specifically I have a pretty nasty EVO sportster engine, that I would gladly give anyone a $5 bill to tell it apart from is 1986 EVO counterpart, all though it is newer

I could. Not to argue with anyone but cant all of these "new" class engines run in a current (pre these new classes) class?

Again, I really wasnt trying to start a pissing match. I will go back to my corner now

There are two things to keep people from breaking the 1986 rule.  Their conscience, and the S/N on the motor.  
I would hope that the former would be sufficient, but the latter would be easily verifiable.  

As for the point of classes that you can run in.  You would be able to run in Twin, Pushrod, or Classic if it wre pre-'86.
That is the "let those who ride decide" paradox.

First, I like the new classes....great ideas. I have some questions/points on this class, however.

Unlimited engine mods, but no enlarged oil cooler allowed (oil capacity)? And yet you can alter the cooling fin design, size, and placement??
"Modified oil system" is very vague. Some bikes have inherent oiling issues, as from the factory. And you will find that the 1986 Suzuki GSXR series had a huge oil cooler and oil spray jets from the factory....but older designs had no such advantage.
I guess I don't understand why you would limit cooling on an air-cooled bike (with the exception of making it water-cooled, of course). That seems like a great place for some old-fashioned racer ingenuity.
Anyway, as I say, I love the general idea. But I think there needs to be some clarifications, and perhaps some further considerations. Then I will start shopping.  :-D

Shane,
I don't think you need any clarification.  You appear to get the letter of the rule very well.   I think that the issue is that you don't necessarily agree with it, and that is a whole other matter.  
The reason we chose to write the rules as they are presented is to keep the class competitive for the vast majority of motorcycles that were built in  that era and keep the class affordable for anyone that wants to get their feet wet in LSR racing.  There are always anomalies that will happen and there are some instances of bikes that will have an advantage in certain classes. We can't stop that.  In fact, the bike you mention was brought up when we made the choice of what year to make the break because we have a '91 air/oil cooled that did 250 in September.

A lot of discussion took place with regard to what lengths would be taken by the open up the wallet crowd and we were given a great history lesson by Kevin and Scott about the lengths that drag racers went to  squeeze out every inch pound of power that essentially turned air cooled bikes into oil/nitrous/water cooled bikes that happened to have fins which would go against the spirit of the class.  It is the same reason that EFI is not allowed to be added.

If I were you, I 'd add an '86 GSXR to my christmas list.

AS for the vagueness of the modified oil system, We will present clarification.

Thanks and all the best

To further this point, I spoke with Bill Warner this morning. (He is recovering nicely and we will see him this summer.)  He did 311 on a bike that does not have a cooling system.......
