Newbie 1963 dream troubleshoot

[se7enGt0147]

Hello I am new to this forum and is desperately seeking for advice from fellow Dream owners. Thought this forum would be the best place to help me find answer. I bought a really beat up dream about 2 months ago for 100 bucks. A father and son project. My dad having previously worked on the honda benly CA95 and other bikes, ripped the Dream apart, gave it a new paint job, and engine clean up. We put the bike together, started it and we found out that only the right side of the engine runs. Smoke comes out from both of the exhaust pipe, but...Only the right pipe is hot, while the left pipe is cold. Same goes for the exhaust header. When the bike starts, only the right side gets hot and the left remains cool. We tried everything we could think of, the timing is right, we even tested the coil...Right now my dad is thinking the problem has to do with the valves and the clearance. Any help will be greatly appreciated! Please advice.

Hey there,
I'm assuming you pulled the plug on the bad side and checked that the plug IS firing?

did the bike run before you took it apart? thats what i usually check before i tear a bike down. Once you know if it runs or not then while you have it apart you can decide to rebuild the engine. I assume you put new plugs in it, set the timing and adjusted the valves before you started it?
