I stored my 88 Phazer outside 5 plus years ago, so needless to say it’s a little rough lol. Fan side cylinder must of got water in it because when I pulled the plug it was completely rusted. I’m completely up for rebuilding the motor but outta curiosity I was wondering if anyone has used different model of Yamaha engines in those years to replace the original 485cc. If so was it a fairly easy or over complicated? Curious to hear what you guys have to say? Thanks in advance Kyle.
