I currently have an early 1975 850 commando of my own in need of a replacement cylinder head. It is not electric start and it has front disc only and right hand shifter. Will a head stamped RH4 work on this bike?? Are the rockers and spindles interchangeable with the original head I have if needed??---------- Thanks to all who helped with my friends bike that was kicking back. I did all the suggested repairs and it seems that there were many contributing issues. The bike seems to be running fine now. I have kickstarted it about 10 times with no problems. I am hoping my luck will hold out. It had bad wiring connections in all the usual places, bad battery, low voltage and I had the timing slightly too far advanced at 5000RPM, I replaced the Boyer, ignition switch, battery and bypasssed the kill switch. I also replace the trigger wires. I will never forget the good advise and I will use it now on the two 850s I am building up for myself. I will be sure to follow your advise before I give mine it's first kick in 17 years. Thanks guys!!
