Jay, there is definitely ecomony to be had with the mass production and
poularity of the Japanese motors.
But perhaps that just points out fact that the class probably should have
looked at Japanese rather than Austrian 2-strokes in recent years.
The latest japanese 600cc snowmobile motors are popular also and much more
simple than a 4-stroke to rebuild.
Why shouldn't a Suzuki snowmobile engine be even cheaper than a Suzuki MC
motor to buy and maintain? They may not make as many of them-but they sure
have a ton less moving parts to assemble and adjust.

Chuck, I know you are opposed to this direction. I have also been
concerned
about costs but I am now convinced that there are multiple sources for
engines & rebuilds that are very much in line with the numbers I have
posted. I have found multiple sources that will do complete 600cc rebuilds
with all new pistons, rings, bearings & valves for $1500. This is
extremely
reasonable IMHO.
Additionally there are multiple mini sprint santioning bodies that have
bone
stock classes & they do not seem to have problems keeping things legal.
F1000 has a stock engine rule. I have spoken to George Dean who is one of
the most respected engine tuners in the business & he says that if you use
the stock ECU & aftermarket exhaust you can get an additional 5 hp on the
1000 & about 3 hp on the 600 engines. Much more hp is available with
significant engine modifications and aftermarket ECUs. These will not be
legal if the 600cc engines are ever approved.
I suggest that you let this play out to see what happens.
Thanks ... Jay Novak

The prices that we have so far for GSXR600's do NOT appear to be factory or
factory dealer list prices.
Those are salvage yard prices. See Jay's post on the Eformula site.
If we want to play that game, the price on a low mileage Suzuki 600
2-stroke
with EFI and ECU is a in the $1000 category. I checked this AM with a
dealer in Thief River Falls where the factory salvage yard is.
Rebuild prices have not been compared properly yet either.
2-stroke rebuild parts have to be cheaper then MC parts since the 2-strokes
mainly only need 2 sets of rings and 2 pistons/pins, not 4 ring sets and
piston/pins+ 20 valves and valve seats plus cam parts and many more seals
and bearings. 4 throw crank and 4 rods isn't cheap either if you need go
that far.
Freshening up a 20 valve MC motor has to always include doing 20 valves and
seats also. Then setting valve lash on all valves and retiming both cams. +
new timing chain/belt.
