I stopped at Town and Country Suzuki in Gilbert AZ today and talked to both
the parts guys and the service guys. This is a very large dealership with
Internet sales.
They very rarely replace an entire motor (they repair instead) and do not
stock complete motors.
New motors are around $5500. That was a VERY rough estimate the parts guy
gave me w/out looking it up.
They say that the most popular expensive motor problem is that someone
over-revs and bends the valves and sometimes destroys the head.
They sometimes replace the entire top end (head and valves) Sometimes just
the runined valves
If one blows up the lower end-they fix it and use the top end on it again if
they can.
They ocassionally just replace all the lower end bearings where someone has
probably set the idle too low-the Service guy says that he thinks the over
12:1 compression motors don't like low oil pressure from low RPM's and
pound out the bearings.
They have discount Internet pricing and a GSXR600 crank is $607, rods are
$300 a set of 4. Bearings, gaskets, and shims are extra-forgot to get their
prices.
Labor is $84.50 an hour. Very rough estimate of 25 hours to do a lower end
replacement. ($2112 labor only)
Forgot to get a price for a case. Might not always need one.
Other Rebuild parts using their Internet site prices:
Factory Piston and rings $101 per hole, 4 sets is $404-they recommend forged
aftermarket pistons-they say they last twice as long and cost about the same
as factory parts.
Valves, about $30 each average. Set of 16=$480
CR said he got a price of $16 and $24 each for valves, that would be $320 a
set of 16. Don't know if that was a GSXR600 or just something similar.
Guides: $6 and $8 each.
Labor to adjust valves on a typical good 16 valve motor not needing any
parts, 3 hours at 84.50/hr or $253
Finally, the Suzuki service guy I spoke with said that his own opinion was
that Honda motors last twice as long as Suzuki and that the order of
preference for durability was Honda, Suzuki, Yamaha, and then Kawasaki.
Oddly, Honda also makes the most HP in the 600cc class.
He says that salvage yard (Internet or otherwise) motors can be very good
deals since many people who crash them do it early in the Bike's life.
Also said that recent model street bikes are usuallly short shifted and in
pretty good condition when they are crashed. Very few people can ride flat
out on the street.
However, we do have some illegal canyon racing on the East end of the valley
on the Apache trail.
I have also heard from the guys that I work with that race that there are
plenty of people out doing track days with their street motorcycles. But I
reckon that the sessions are probably not very long compared to a real road
race.
Finally, Phoenix may be unusual as an area for racing street bikes-we have
3 major race facilities across the valley, each with several race courses.
(FIR, PIR, and AMP which will reopen this fall)
