i have done 3000kms on my wr450 2005 model and thinking of a rebuild piston and rings. the dealer says it should be done every 2500kms is this right?

seems premature but i don't want to blow her up.
a rebuild will cost around $1000 Aus

i mainly use it off road on fire trails.

what do you guys think? :lol:

Change oil, clean air filter, check valves and ride it. It's not a crf, that motor should still be fresh!

over 5,250k's on my '05 and purrs like a kitten (on steroids)
oil change every 300k's (filter every second oil change)
air filter every ride
95 premium unleaded with valve saver fluid
valves checked every 800k's (haven't moved since first service at 300k's)
and as you know Anthony, it gets ridden reasonably hard and often - i make sure that it earns its keep !!
see you on a ride again one day at Dissa and you'll get a chance to give yours a good caning !
cheers ..

Thanks Guys,

i thought the dealer was talking bull but after owning a CRF i am weary of maintainance interval and preventative maintainance (the crf cost me a fortune to rebuild). the bike starts easy and runs great, i will put the rebuild to rest for another 3000kms!

Your help here is really appreciated!

re disa (pcof) i can't wait till winter so i can try telecom hill !!! in the meantime keep in touch brother :lol:

FYI you could do the re-piston/re-ring by yourself when the time comes. No maintenance on a bike is worth $1000 IMO, particularly such a relatively easy one as this.

Buy a Haynes/Clymer manual and you'll seriously be all set. Grab a buddy who knows what he's doing but there really is nothing to fear about the swap.
