maintenance intervals??

5 posts in this topic

i've got an 08 yz 450 i picked up in january. i put an hour meter on it before ever lighting it up and i'm up to 32 some odd hrs. what should i be planning to do here shortly? i haven't bothered to do anything other than oil changes every 3-4 hrs. haven't even checked the valves yet because it still starts easily. when should i check/shim the valves, do the top end, replace the valves? also any info or estimations on the clutch, and suspension service intervals would be killer. if it helps/matters, i ride quite a bit and race (off road A) twice a month. thanks.

I'd rebuild the suspension at somewhere around 10hrs initially due to the parts breaking in and contaminating the oil and then again every 30hrs or so. So bushings seals and fluids at the very least for the suspension. Might check the clutch plates. I also go through the bike and grease all of the bearings every 15hrs just to keep it fresh.

If I only use my 02 426 for enduro (not racing, just going around in the woods), how much can I extend the service intervals? Racing/MX puts a lot more of stress on every part of the bike...

I ride woods and change my oil in my 01 426 every 3 ride days. And a filter every 5-6. Filter is always still clean, but better safe than sorry. Id rather spend $9.00 on an oil change than $1800 on a rebuild.

I don't see the need for that. The bushings were fine on my oldest '06 when I did the seals 6 months ago, and the seals lasted over a year. But it is a good idea to dump the OEM fluid early.

Re-grease the steering head and linkage immediately with a water resistant, moly bearing EP grease. Your dealer might have done this ( I know a couple that do ), but don't count on it, and the factory grease is sparingly applied, to be polite.

As far as valves go, check them now for reference, then again at 10 and 20 to see if any of them settle into the seats, then after that, every 10 ride days, give or take. Shim them when they need it, which may or may not happen as long as you own it.
