The Iridium plug seemed as though it didn't unscrew, but it was just really tight. I had to assert my authority with wrench and pliers
YEA BABY!!!!! See that, scooterbob had them magic hands on my motor. Wait, that did not come out right?
O got a peek inside mine when the upgrade was done, it's a very impressive motor, I suspect it's over built.
I'm on 8000 miles and I swear it is still getting better, I'm super happy with my little red bike.
YOU got the thrust washers installed on both sides of the fourth gear on the mainshaft ..... if the thrust washer is M.I.A. from the right side of the gear, it'll fall into the engagement dogs of the next gear and rattle when the bike is leaned to the right ....
I always wondered what the rattle was on all the C5's I have ridden so far when you take a deep right turn. Could you please elaborate to what actually you did to eradicate the rattle. M.I.A ? Domestic C5 never had the gear problem which the initial export bikes had so we never got anything in the gear box fixed.
