Headache

Didn't get a ton done last night, but I am moving in the right direction. The tv in the garage hinders my productivity.

Stamped to identify the proper parts.

New seals 

I like to pre-oil everything before installing  

new seals in place

Installing the valve springs. A little assembly lube on everything that has metal to metal contact isn't a bad idea, and it helps hold the little retainers in place. They're still a hell of a pain to place though. Also note back on the table that the tighter coil of the springs are at the bottom, remember this when installing them.

Old head on the right, it's interesting how much the casting has changed I don't know the build year for either but I would guess that the one on the left is newer. They're both from the same model of bike.

And this is why the old head's being replaced

 new head:

New on the left. By the way when I say new I don't actually mean new, it's off the motor for one of my other bikes and almost as old but it's "new" to Loudbike. 

Again, I've stayed up too late, and this is where I end.

Lapping it up

This is after a real good cleaning. This head is from a motor that wasn't supposed to go on this bike, so I had been doing a bunch of cosmetic work to it which left it full of metal. Lots of carb cleaner, brake cleaner, WD40 and a full disassembly (minus the valve guides) later and I've got this:

 Not nearly 100 percent, but it's better than it was and for this bike I wasn't planning on modding the motor all out like my other bike. Also with gas at $3.29 and a full size van to drive I want this thing back on the road now.

Before and after (intake)

After cleaning each valve I lapped them all in by hand, I'll have to get one of those little suction cup sticks for the next job... but how will I hang it on the wall?! The intake seat pictured is not in good shape, you can see the pitting that could lead to loss of compression, I'll have to remember this when she's running so I can test it.

 ... and exhaust. This took a while with them chucked lightly into a cordless drill and a couple different grits of Scothbrite.

When I got done with this I was shocked to discover that it was almost midnight so I had to call it a day. With a little luck by the weekend (two days) I'll be able to test ride.
