i just took it on the freeway for the first time and I noticed it won't go passed 75MPH
now Im wondering whats up...
maybe the oil is bunk???
im gonna open up the oil filter and see whats going on,
could a pinched O-ring be the cause of this??
Even if the vacuum port was not blocked off, (it for sure should be) that would not cause your lack of hi speed power.......
neither will the type of oil......
neither will an oil filter gasket......
and as you found out the hard....rather expensive way,...neither did the vac petcock,.....even tho it could have. Too bad you got caught up in the "vac petcock paranoia syndrome", but at least now you won't have to worry about the petcock starving the bike for fuel. And as long as you don't forget to turn it off, you won't ever see your carb overflowing into the oil in the crankcase either.
Lacking hi sp power ? Hard to say,.....but did you try choking it a click or 2 when under WOT ? It mite be running lean, but I would think it would be surging then too. If choking doesn't improve it, maybe its running too rich.
