How many miles can I expect from my bike.

Simple question for you old two smoke heads. How many miles @ roughly 5000
miles per year can I expect out of my low mileage (bought with 5700 miles
and the top end rebuilt shortly there after). I know the top end goes out
at about two or three times the rate of the needle and ball bearing low end
which I figure might go as much as much as 40K miles. I'm past the "babying
it" stage with freeway average speeds around 80-90 and the tach gets pushed
close to redline quite a bit in the canyon. I usually get it up past 100 in
spurts on the weekend too.

I had those new carbon fiber reed valves put in and the front brakes bled
last week, plus a burned out tail light fixed. The brakes are way better
now and the low end is snappier with the new reeds (more power wheelie
prone like the old RD's now). The reeds that were in there were weird; a
two piece Teflon material with holes on the outer set and no stops. The guy
doing the work had to find some stock Banshee stops to use with the carbon
fiber reeds.Also, on another ride the week before I was informed that the
oil pump only works off the throttle so at steady speeds I make sure I let
off the throttle and goose it at least every mile. I had three RD's back in
the 70's and put at least 20K on them without any problems so I'm figuring
the at least the bottom end is similar on the water cooled RZ's.

Krusty, Tim, what do you think from a non racing perspective, what sort of
mileage I can expect from my bike.
