Looking to get a WR to motard out and also do a little dirt before the conversion. My question is, the 400 was the early model, and is a bit cheaper than the 426. Should I hold out and spend the extra $500-1000 for the 426? I also was told buy a gentleman with a 400 already converted to motard that the 400 had steel valves rather than titanium in the 426, thus making it just a tad more reliable. So whats the gen opinion? 400 or 426?
