daily 4-stroke Maintenance

[bpositive]

Just made the switch from 2 to 4 stroke(cr250 to crf-450) -Wow what a difference... i ride all weekend usually practice one day race the next or reverse..so my bike works hard 2 days a week..
i use a fresh airfilter every ride.

As for a maintenace goes how often do i change:

1.Engine oil
2.Oil Filter
3.Trans Fluid
4. check the chain

Am i missing anything that i should do weekly to keep this beast in line?? Drop some knowlege on me please ...

weekly - not that I can think of.

I'd focus on the same things you are - chain, tires, air filter, oil/filter plus check spokes, and not quite weekly, but at some point - keep up on the valves....make sure they are within spec
