My friend just bought a 2002 YZ250 and he starts it, and then revs the crap out of it after only a few seconds of idle, then continues to rev it up and down for a minute or so to warm it up.
Him revving the engine like that when it is still cold makes me cringe when I hear it. I told him I think that is bad for the bike, but he says "all the guys do it at the track - it clears out the bike and keeps the plug from fouling". I figured who cares if the plug fouls once in a while - better the plug than ruinning the non warmed up clyinder, rings, piston, etc.
So what's the right answer? Do all the guys do it because they get a new bike every year anyway, and just don't care, or is revving the crap out of a cold bike the right thing to do?
On my 04 KDX220R I warm it up by givingg it just enough gas to idle smooth until it warms up. Seems like this is way easier on the bike, no?
Thanks a lot,
Phil
