Re:Changing the Front Fork Oil 1 Year ago  
Yami doesn't recommend any interval, my Clymers manual suggests every year. Both are a little extreme.

I think a lot of it is by feel, but some things I noticed:
- front end was way spongy, especially on hard stops, and I could rock it at a standstill almost down to its stops
- bike became squirrely / wobbly on the highway
- bumps went from feeling firm to sharp and annoying
- front tire unevenly wearing/cupped
- the bike was no longer fun to ride
- mine became custom lowered - everytime I sat on it, the whole thing dropped.2 inches

Mine was an extreme example, as I'm pretty sure my springs were shot too. I plan on doing mine every other year with average riding.

I change mine when I change a front tire. They seem to last about 10-12K miles. It usually is dirty, shot to hell if it is the original oil. AI use Bel-Ray Synthetic in my forks, but you can use what you want. There is a huge variety of options at shops that do off-road.

The interval depends on how much the bike is ridden more than time. I change my fork oil about every 15,000 - 20,000 miles or every couple of years. If it is close to the time to clean and repack the steering head bearings (Yamaha recommends every 16K) then you can kill two birds with one stone.
