Good morning all , just got this bike on a trade, was told it was an '07 yz450f, and under further checking the 10th digit shows more likely to be an '06 ?
as my 10 digit is a 6, but why are there 07 possibiilities, due to late year builds ?
There are 4 possible matches. Year Make Model VIN
2007 Yamaha YZ450FWL
TEAM YAMAHA BLUE/WHITE
2006 Yamaha YZ450FV TEAM YAMAHA BLUE/WHITE JYACJ10C36A000051
i know its not a yellow black...
concerned about the loudness, i pulled the valve cover this morning to check cam chain tension which was ok, so im going to change plug while in there, and i pulled out a 9 instead of an 8, which manual shows for an '06, what issue would a hotter plug cause ?? also is an iridium better , worth the extra $ or not ?
thanks in advance
