1981 CB 125s cam sprocket bolts

[LukeDelRocco]

Hello DTT,
This is my first post here so I'm not positive that this is the right place for this thread but here we go.
I'm in the process of changing my head valves, and I can't for the life figure out how to get the bolts that hold the cam chain sprocket on off.
Any body have some tips or tricks?

So is the issue that the engine is rotating while you're trying to take them out?

Yes,
I took a break from wrenching for a bit..
But, just thinking about it holding the crankshaft will probably do the trick...
I also can't get the crank shaft bolt off...

Put it in gear and ratchet strap the tire so it cant move.
Or get a buddy to hold the tire.

Or put it in gear and stick a hammer handle or dowel through the spokes so that it catches on the swingarm. If you use enough torque to break a spoke, they need to be replaced anyways.

I used a penny in between the crank and primary gears.

Penny's softer

Although I'm told gold works too for the super loaded mechanics out there.

Got the cam sprockets bolts off,
and I didn't have to use any of my gold, which is always a plus.

Not anymore..dime is only silver plated. Coin cores are all the same. Quarter is same as dime too...

FWIW, though, silver is a soft metal too....wouldn't hurt the gears. They used the penny because you don't want to ruin a quarter.
