Gooch, great to hear you got it figured out, it gives me some hope right now. Any updates on how the bike runs today? I am having a very similar problem with my 78, and I went up 1 on the pilot and 2 up then back down to 1 up on the mains (UNI pod filters and some aftermarket straight mufflers)...and it will not idle with the choke off. This was after cam chain adjust, valve adjust, and ignition check.
Just wondering if you've been fouling plugs or riding just fine since upping your pilot jets...thanks!! Or for anyone else reading this, did you really have have to up your jets that much? While I realize every bike is different, it seems a bit extreme compared to most people's setup.
