Put her back together, new head gasket, retainers and keepers on the valves, checked the gap again with the springs installed, A-OK.
I had one new plug so I saved it to get a reading.
Fired her up with an older plug, took quite a few pulls to get her going, 10 or so, I used starting fluid to coax her along.
Wondred if I clocked the cam wrong, then VAROOM!
Off the bat she sounded better, idling at 1800 RPM, I adjusted the Mikuni to 800 RPM and tweaked the carb while letting the motor warm up.
I brought the Rs up but never went over 5100 .... she sounded nice ... there is a SLIGHT miss that at this point I'm gonna say is carb jetting or running with no load.
It was not spitting ANY gas out the back of the carb.
I am 100% sure it was bent valves "maybe just the intake (?)" and I had made the problem worse when I repeatedly tried to reach 7000 RPM.
I am also convinced the valves that came in that motor while correct for the motor are not capable of 7000 RPM.
I put in a new plug, brought it to 4500/5000 RPM and held it there for 2 mins or so ...
The plug looks just a tick rich with a 125 main jet. Should I go smaller?
I want to personally thank every one listed below here (and any I missed!) for sticking it out and getting to the bottom of this.
I cant speak for everyone but this was real learning experience for me.
Thanks!!
