Absolutely. An easier method is to spray down the whole engine/frame of the dirt bike with WD-40. I know a lot of guys who live in wetter climates who do this. Works well, but in a dusty environment, either method tends to pick up some dust. Rinse and repeat. My KTM has a nice coat of WD-40 on it right now.sevenboarder said:I had asked my dad for tips for salt/rust prevention. He mentioned that he knew some bikers (the louder type) that used to wipe down their bikes with a rag that had a little bit of motor oil (i.e. 5W-30) on it. I guess this would prevent the moisture and salt from getting to the paint. Has anyone ever tried this? Or heard of it being done?
