Mutt, do you have any ideas where to look next. Engine rebuilt. New new seals throughout the engine and Crank. Leak down is fine at 6 psi.
all electrical is new in the ignition. Timing set by depth gauge and Fluke Meter. Runs fine at low to middle RPM. Just stalls after 3/4 throttle.
I am questioning Carb and exhaust right now. Very simple carb however I am beginning to question the needle. Also this is a straight exhaust. No expansion chamber like the one in the video.
Lastly I am questioning upper end in its entirety. I used the existing 10 over piston but installed new rings. Would the bike run a low to mid RPM if the rings got damaged during rebuild?
Thanks for jumping in. Back to the bike today for me. I have learned a lesson here and that is to stay in my wheelhouse. I refurbish 1960 to late 1970's enduros. I thought that this would be simple, my mistake!
