Wow! I can't believe he still has some. That's incredible. Before I pull the trigger, how well do they actually work? I have a clutch brake on the bike currently (which works well but I want to run a torque converter).
Does anyone have information on how to do a drum brake/sprocket set up like the cat r4002? Did they have different wheels? I don't see how a drum sprocket would line up properly on the current wheel
Did you use 1.3 ratio rockers for Honda/clone engines? Also what's the part number on the 5hp head? The only part number I've seen is 37474 but I'm not sure if that's the smaller one.

I was running Honda 18lb springs, the motor had 6 hours on it, and it broke at the retainer. It didn't appear to have any coil bind issues but apparently I was wrong�� the holes in the head make it seem that the valve actually went through the head, came back down into the cylinder, then went...
A friend of mine was riding my Dirt Bug with a modded Predator, not pushing it too hard (4600 rpm) when the was a pop then it locked up and had no compression. After tearing it down, the culprit was the intake valve had failed. Beware of this issue, i was running stock valves with 18lb springs...
