Hi All,
I purchased a 2003 Honda BF 50 with 85 hours that had a broken cam pulley for a really good deal. My intention was to use it as a spare parts motor for my 1997 BF 50. I was suspecting the broken cam pulley caused damage to the vales, heads, and piston. But after taking the heads off, everything seems to be in order - the valves are not bent, the heads are not scored, the pistons look fine. There is no warping of the block or heads, the fly wheel turns smoothly in fwd/reverse/neutral. I am guessing when the cam pulley broke, it did so at perfect timing and all valves shut and did not reopen. I am now thinking it makes sense to replace my 1997 and fix this one. Other than all the gaskets, the only true parts needed to get this running are the Cam Pulley (Pulser Rotor) and the pulser coil underneath. (I will replace a lot of other things as well if I got this route - spark plugs, anodes, impeller, thermostat etc).
Does anyone have any ideas on what would have caused the cam pulley to break? I have never seen or heard of this before and am stumped.
Am I overlooking something that should be checked?
Thanks in advanced.
