I ride an 04 CRF250r on trails and sands. Use NoToil products. They're alright but in high temps (>90F) the air filter oil seems to melt away so i have to clean and re-oil the filter all the time, once a week for me. I got lazy once and left my oiled air filter on my bike during winter months. This was a bad choice. When I got my bike out to do maintenance a couple of months later, I found that NoToil ate up my filter. It easily tore in my hands like an old shirt. Won't do that again. Cleaning and changing the air filter all the time as I do is a pain but on the bright side my air filter is performing at top level and I know its always clean. I have 2 air filters that I alternate, while I'm using one, the other is clean and sitting on my shelf ready for action. I'm not a big fan of the NoToil air filters though, they are too thin. I buy the stock Honda ones. Don't use a filter sock. I like the Maxx Chain dry lube. As far as engine and trans oils I just use the Honda pro stuff. I change those oils all the time too. Never had any problems.
