LSR Record Book Classes
Here's a table showing the records in the common classes that a Buell
owner might want to target. If there's nothing listed, it means it's an
open record. Although I did my best to track down and list all of the
numbers, please double check that the information of interest to you is
accurate before embarking on an effort to build a bike.

So what do all these class letters mean?
Well, to the left of the dash is the "frame" or more accurately,
it describes the chassis. To the right of the dash is the engine. You really
need to get a rule book to see all the particulars, but I'll give a brief
summary as I understand them.
Your options for the "frame" portion of the class are:
P (for "Production") - the bike has to look completely
stock, and the burden of proof is on you. Be sure to bring documentation.
Service manuals, owner's manuals, and parts books are good things to have
with you. There is a 500 unit homolgation rule as well.
M (for "Modified") - A modified frame means a normal
motorcycle chassis, with some modifications allowed. It no longer has
to appear stock. There are some restrictions on wheelbase, peg location,
fuel tank capacity, and so forth. No streamlining forward of the rider
is allowed. As that relates to Buells, it essentially means you need to
remove your fairing or flyscreen.
A (for "Altered", also known as "special construction")
- this is just about anything goes, including multiple engines. Again,
no streamlining forward of the rider is allowed. To get a Buell into one
of these classes, you MUST do something that makes it illegal in the modified
class. For the RR1000, we put on some rear sets that made the footpeg
position illegal in modified. One of the Sportster list guys went with
a small gas tank that was illegal in modified. There may be other ways
as well to easily cross into Altered.
MPS (Modified Partial Streamlined) - Same as modified, but streamlining
is allowed, within certain limits.
APS (Altered Partial Streamlined) - Same as altered, but streamlining
is allowed, within certain limits.
Your options for the "engine" portion of the class are:
PP (for "Production Pushrod) - the engine must appear identical
to the factory engine, must use the original carb with no boring allowed,
as well as original equipment cylinders and heads. All modifications must
be out of sight. This motor category is only available with a Production
frame, and that's also the only frame class it applies to.
PG (for "Pushrod Gasoline") - Anything goes, so long
as you still have pushrods and you run it on gasoline (by the way, you'll
have to use the gasoline available at the event, and the gas fella will
seal your tank).
PF (for "Pushrod Fuel") - Same as PG, except the fuel
is practically unrestricted. Nitrous, nitromethane, alcohol, or even your
own gasoline that you brought to the event will put you into PF.
PBG (for "Pushrod Boosted Gasoline") - this is a pushrod
gas motor that's also boosted, i.e. a turbo or a supercharger.
PBF (for "Pushrod Boosted Fuel") - this is a PBG motor
with unrestricted fuel.
In addition to the preparation allowances, there are certain safety requirements
that apply to motorcycles. See the rule book for details. You can get
a rule book from USFRA: http://www.saltflats.com
So, as you can see, there are lots of ways to build a bike, and there
are good records and vulnerable records and classes with no record at
all. I hope to see some more Buells going for records this year!
