With 11.000 "soft" Km´s on my 2008 wr450 I’m planning a top end rebuild.
Oil changed every 500km, air filter once each other ride. Valve clearance needed adjustment only once (at 10.000km)
Decided to do a top end because of the sound (not too loud anyway). No sensible power loss, little oil consumption, it´s more "preemptive" than other thing.
Already bought piston, rings, pin and gasket. Also a new cam chain. We will see about the valves when we open, but I was told not to expect them to be wrong-
The moto dealer told me (knowing what most of you think about moto dealer´s advice) "You should do the bottom end too, because once the top end is up and compressing high again, the rod, bearing, etc will be exposed"
What do you think about that? Should I go for the bottom end ,too? How many more "average" km´s should i expect it to do without intervention?
I can afford the parts, just don´t want to waste time making my mechanic open the crank and changing parts just because....
