Is there any thing wrong with just routing the breather hose down along the shock with the carb hoses if your not concerned with water. Newbe to 4-stroke.
Nope, but you may as well just leave it stock because you aren't any less likely to suck dirt or water from either spot.
SureBlue- I had forgot about the beer, thanks for reminding me! Definitely do the carb breathers if you ride in water at all... I'm not sure what the 450 carb looks like (I will before too long though!) but I just routed the upper 2 into the airbox on my 00 426 and never had any more problems with the bike dying in deep water.
