Help needed on what class to enter

[Russianbirdman]

I have a couple questions on class options:

What class would I run if my 2012 1000cc bike has a 520 chain instead of a stock 525 chain?

What class would I run if my 2012 1000cc bike has a 520 chain instead of a stock 530 chain and a non-stock windshield?

Thank you

you need to supply a bit more information for help with the question

modified partially streamlined
so you just as well put a pipe on it...

Other than the modified items that I mentioned, the bike is store bought stock.
My decision to enter a particular class is based on an evaluation once I get the correct interpretation of what class I would belong in after any of the listed modifications from the stock configuration.
If you require any more information to provide me the right answer, please let me know.

I may have to do a little soul searching on how far I what to go with the mods. The bike is engineered pretty well to act on it's own, but I'm toying with a couple of minor mods. The addition of a pipe would run into other management systems. I put a Remus can on and "it" didn't like it at all.
Still open for advice.
Thank you!

With little other info on the bike - I would agree with Stainless -  MPS  Modified Partial Streamline, as a result of the windshield. Do you really need a windshield ?
maybe scrap the windshield and run  M -  Modified
1000cc what ?   Overhead cams ?  - pushrods with cams below cylinder deck ?  Need more info to finish classify.
Another maybe meaningful suggestion would be contact AMA and get a rule book, or simply down load the latest version from the BUB racing web site.
Treat it like your LSR bible. .  .  Read it a couple times a month during preparations.   Just a thought.   
Keep it fun -

My first years on the salt were in the 1000cc modified partial streamliner class when they allowed production engines.  It would be a tough class to set a record in.  It can be a lot of fun, though.  There is quite a bit freedom in the rules and it will give you a chance to try all sorts of interesting things.

Sorry... I don't mean to dole out a little information at a time. I should has stated the make and model. 2012 BMW S1000RR. I'm not sure of the engine configuration. Only that it is stock. I am not set on a  windshield change, just asking where the two mods would put me in a class with either combination.

How is it that you do not know that your bike is a dual overhead cam inline 4 cylinder.

It's new.... he doesn't work on it, he just wants to ride it fast... legally...

So just leave it completely stock, no changes, ride it to the races... enter it in production... go fast in steps, start around 125 and work your way faster staying comfortable with the speed.  Riding on the salt is a little different than pavement... you will learn throttle control or you will be looking for a ride to SLC to buy a new tire.
Be safe
have fun
then go fast

See ya on the salt

Yes, I understand it is an inline 4 and that the valve train geometry is modern day for a 14,200rpm motor. I understand cylinder quantity isn't a factor.

Thanks Stainless1. Yes, just looking for an easy answer to what turned out to be I guess a half question. My fault but that's okay.
I ran in the RWB in 2010 and 2011 with a BMW K1200S. Got that bike to the 160+ mark. Just looking to run the S1000RR on the other courses to hopefully get 200+.
Thanks again, looking forward to it!

Well, If you get your stock 1000rr to 200+ you'll have the record in PP.

I think your starting to get the order of things.......100% showroom stock = Production.......Any mods of any kind = Modified. If the stock bike has no streamlining.......OK.......but add a windshield and your in PS...Partial Streamlined.  If your going to actually enter a class, you should study what is allowed to be removed or altered.......ie, signals, lights, handlbars etc.  Also be aware that you have to have the correct or better 'speed-rated' tires for the existing class record.

Have some fun at 175 (maybe) on the Mountain Course..........then you can move to the 'Big-Boys' course.

Birdman, it would be very interesting to see one of those BMW's run with some genuine streamlining.  No one is doing that now.
