Well its been a long time since last posting here. When i last posted i had a good old smoker (pics in a topic i made) I've now bought a brand new CRF450 2010 for a very nice price. Couple questions. 1. I'm running it it, I'm not doing it how Honda say but how most topics on these forums say. Is this right? Ride it like i stole it, but not letting it bounce on the limiter. 2 Manual says 15hours to replace piston??????? i got more than that out of my 2-stroke 250. Is the just the cautious approach and will i get more out of it? I'm not a pro or anything and don't thrash it around. 3. I have more but ill post when i think of them. Thanks ~3832always P.S.
