74 CB 750 Recent rebuild leads to frozen kickstart
« on: May 25, 2015, 01:11:32 PM »
Im very new here and managed to get by with a good friends help and Honda mans book. It all started with replacing second gear during the early winter. Previous owner must have loved to power shift and the lack of second was killing me as a novice rider. A good pal of mine helped me during the tear down and we replaced the piston rings, honed the cylinders, and tuned the valves on the top end. Replaced the shift drum and forks with a newer pair. After cleaning the carbs thoroughly and being patient with reinstalling the clutch we tried turning it over. Drained one battery and I dropped in a fresh new one the next day to have the same issue. My biggest concern is the starter seems fine and strong along with the battery and carbs. I cannot for the life of me understand why the kickstart is frozen unless i press the electric start in which the kickstart free's and can be kicked but only half way. After months of slow and steady work I am learning my lesson that these old bikes can surprise you every step of the way. When the case was split I made sure to leave the kickstarter and spring alone. Im now worried that this could be an issue with the transmission it-self. Any thoughts would really help cause im shooting in the dark now and really concerned that if the bike does start will the transmission be okay since the kickstart is locked and more importantly whats my next step besides going back and cracking the case again?

Moderators, any chance you could move this into the Tech/SOHC/4 Bikes, this is a CB750K4 not a Hondamatic. Figure it would get more traction if it's in the correct forum.
1972 CB750 K2
1997 XR600r (street legal)
1975 XL250
