FM was the largest Mod class in 2005 and 2006 also. Missed it by 1
in 2004 when DM was the largest.

Unfortunately, you cannot disconnect the Solo interests from the GCR
very well since it is the basis for the Solo cars as well.
In any case, we would like to see you survive as a road racing class
and I am sure most of us on the solo side will do all that we can to help you.
No problem with solo participation, BTW.
In 2003, FM was finallly the largest of all SCCA Solo mod classes at
the Nationals in Topeka.
Larger than CM which is the FF1600 class.
Also, the SEB (on the MAC's recommendation) saw fit to NOT pass a
50# weight penalty for the 493 in solo as the CRB did on their
advisory board's advice.
I'm guessing that there were just as many overweight road race
drivers as Solo drivers hoping for the 50# penalty.
The MAC was able to read differently scaled dyno sheets correctly
and recognized the 493 deserved a chance as an alternate motor and
was close enough to the 494 to not require the penalty.
The SEB (on the MAC's recommendation) also acted much quicker than the CRB
on straightening out the balance pipe goofiness.

I agree there is a lot of debating that is going no where, we need
to all discuss the serious ideas and possibilities and get them
down on paper. we also need to discuss the separation of the road
racing rules vs. the autocross group. what we have here are 2
totally seperate groups using the same rules. So what we end up
with is one group wanting changes and the other group countering
it! Its hard enough to get any changes as it is without half of one
group saying yes and the other half saying no, I think a proposal
needs to be put in to split this up. The rules changes we need to
allow our class to live has absolutely nothing to do with the
autocross circuit and they should have no input on the rules or
equipment that we are allowed to use, as such i could care less
what they do in thier group. The proposed wheel change a while back
should have came into play, in the long run it opens the door to a
hell of a lot of choices for rims, rimstyles etc. obviosly there
are a lot of people with multiple sets of 10" rims but i think most
of the road racing class would like the bigger wheels, autocross
could be left at 10 " then we could all sell our spares to them :)
There are only a few things needing attention here, we should start
concentrating on what we need to get into the board. changes for
less maintenance and keeping the cost down.
I myself think the proposal should be worded something like this.
F500 series class engines shall be as follows:
Any 2 stroke 2 cylinder engine 500 cc's or lower is legal for
competition when assembled to fit the following specification.
Aftermarket parts may be used as long as they are designed to be
direct factory replacements.
all engines may use any "Y" pipe, maximum length of assembly from
factory mounting surface shall not exceed 8 " spacers between the
"Y" pipe and cylinder are prohibited
all engines shall use a single chambered exhaust pipe with no
restriction or separators, Separator defined as anything added to
inside of chamber to simulate dual type tunable exhaust.
Maximum compression of any engine not to exceed 138 lbs (tested
dynamically throttle open.)
bore and stroke not to exceed a total area of 499cc
Polishing or re-shaping of any porting is prohibited , with
exception to a re-sleeved cylinder and engines under 449cc's as defined below
A. Re-sleeved cylinders may have the porting matched up as long as
blend marks do not protrude more than .30 into casting of cylinder
and original volume of port is not increased more than .1cc
B. Engines originally under 449cc from the factory may expand ports
by x% total volume from original to compensate for overbored
cylinders. (measured with fluid)
Induction systems:
air shall not be inducted into the engine at any point other than
the inlet of the carburators or fuel injection inlet housing.
Carburators : round or flat slide may be used
a. Bores not to exceed 38mm
b. No part of the body or slide can be modified or reshaped from original.
c. The use of air flow improvement devices of any kind are
prohibited (with exception to factory style air box)
d. powered air breathers are forbidden.
e. any carb adapter or boot is acceptable as long as maximum length
does not exceed 2", angled boots are acceptable to facilitate
leveling of carburators.
Electonic fuel injection:
May only be used with engine models that came stock from the
factory with it.
Bodies of air flow and fuel injection unit may not be modified in any way.
Ignition sytems: Unrestricted
This would allow a lot of engines into the class
some of you may be against the efi thing but i have rode several
different machines with efi and they are a bit laggy and
unresponsive, i dont believe that this will give anyone an advantage.

Hey, Guys,
Please send your input right now. All these postings are nice but
the CRB/BOD need to see the best positive ideas that we have come
up with right away. They are seriously looking at MC motors for
our class so NOW is the time.
Put up or Shut up --- Please.
Jim
