well got the bike running. smooth and quiet. Ran it about 20 minutes in the garage to make sure there were no leaks and the cam chain was adjusted properly. So I took it for a ride, or at least that was my intention for the day. 2 miles from home the motor breaks. It is running on 1 cylinder. I heard something break and it just quit. I scratched my head as there was no warning and i hadn't even rev'd the motor yet, just cruising about 3k rpm. I tried starting it and it runs on 1 cylinder, so i limp home avoiding all the hills. Yes it will run on just one cylinder. It can even go 30 miles per hour. I took a compression test and two cylinders had zero, with 3 plugs all wet with fuel. Took the valve cover off and sure enough a broken exhaust cam in between the number 4 exhaust valves.
Only two possible reasons for this i can think of and that is either i did not tighten the cam holder bolts down properly, or the manual cam chain adjuster was too tight and loading the cams. I did it the way the instructions said to do it. This time i will do what i did when i put one in my bird, and that is to leave it a little loose and tighten it down till it gets quiet when i start it up.
so i wonder also if the valves hit the pistons and caused problems there.
anybody know if the valves will hit the pistons when the cam breaks?
