I was reading on here about how much you guys recommend oil changes. Sounds like 3-10 hrs? Well I have been considering buying a yz450 to use as a adventure bike to do multiple day rides on dirt roads and single track. I could see doing 3 or 4 days of ridding with around 8 hrs a day of ride time. So maybe around 32 hrs or so between changes. Will this kill this engine? I would not be ridding the bike anywhere near its potential. I know this is not really the bike for this, but I want a really light bike for the single track stuff. I have a yz250 now and love it, but the 2 stroke is not much fun on long open fast roads. I was thinking about people doing Baja 1000 and Vegas to Reno race. Are peoples engines toast after something like that? Also, How do people pull off ridding these bikes around on the street as a supermoto? It seems like the miles and hrs would add up way to fast to stay on oil changes. If the engine is not in the upper rpm,s much will that have a big effect on how long I could go between oil changes without abusing the engine?
