For you guys that didnt know i was trying to get an 08 yz450 or an 07. first the deal on the 08 fell through. Then the 07. Well god was with me and I got my 08 for a really good deal. But anyway on my first ride I noticed the bike has some quirks to it. I had some problems when I had a Yfz450 quad so I hope it's nothing major. So does anyone know why this thing backfires on decel? I mean It is constant! My quad used to do the same thing but it was improperly jetted for the exhaust i was running. Could this be that bad from the factory? Also the bike seems to run really lean. Anyone else have this problem? And I noticed a loud rattling coming from the engine near the back. Is this normal? All the nuts are tight and its not the exhaust. Last thing, the front end does not feel really confidence inspiring. Im about 220 lbs and the forks seem stiff and yet soft at other times. Any suggestions?
