Hi, Finished running in a couple of weeks ago, found out what happens after 5200 revs, not bad !!! . My wife has used it all this week and put super unleaded instead of optimax , took it out for a spin last night and after warming it up , took it past 5200 revs , when the vvt kicked in it blew out a lot of white smoke , took several thrashings for it to stop doing it, has anyone else noticed the same, PS my wife wont have took it past 4000 rpm all week
