Jay,
Thanks, but those are prices for buying a prepped motor.

The actual question in mind was what does it cost to maintain a prepped 4-stroke?

Cost of freshening vs number of race miles between them (without overrevs), in other words.

I was making a rough guess that the Ford motors would be a reference point lacking any GSXR600 data.

Dave may have some data from his friend with the minisprint-number of miles on the track between rebuilds and cost per rebuild. (no overrevs)

Might be nice to know what the cost of replacing 20 bent valves, egged out guides, and pistons and rings is also.

Please don't shoot me for mentioning this-but the Zetec hasn't done much of anything to help attendence.

Right now a top of the pine 1600cc Fford engine is $12K & a 2L Pinto is
$13K.  These prices are the result of the continued use & development of
engines that are no longer available and were build when tolerances were not
what they are today.  They also require a lot of maint & freshening.  A 2L
Zetec with FI is $7K & can run or 5K miles between rebuilds.

Thanks ... Jay Novak

Is a Pinto FF motor easy and cheap to keep going??? Like the wagon, it was
cheap and easy back in the day....

Yes Chris, that's right, but then a old wagon should be easier to work on
and prep.
It is a very conservative comparison for what it will cost for members to
have a front running stock 4-stroke-it shall probably be even more than that
since these are more complicated motors than Pinto motors.
