So you guys recommend me torquing them to say 6ftlbs. The smallest torque wrench i have is 3/8's.

If you are worried about the cap bolts coming loose, drill and safety wire them.

Ok, but do you think i should torque them to 6ft.lbs instead of 7.2?I took another pic of the head, and cap. I still need to do a little work to the cap, and polish them both. What do you guys think?The scratch that you can see towards the bottom of the journal cant be felt with my fingernail.

I think I said that. See sunruh's post up a couple too.

You NEED a 1/4" wrench graduated in inch pounds that will run up to 100-120 or so.

:banana:I got it running. Ive heat cycled it about 6 times running it for 3 minutes each time.I also managed to get the cap and journal scratch free. It seems to be running just fine. Ill keep you guys posted as i put some hours on it.:moon::busted:

Also i ended up paying $32 for a headgasket. Does that seem like alot to you guys?

Thumperkid--Basically the only things that were damaged was the exhaust cam journal,exhaust cam, and the cam cap. I took 1500 grit sandpaper with bostitch tool oil, and started sanding very very carefully on the journal,cam, and cap.The cam was easy to clean up since its steel(i think). I kept measuring everything over and over to make sure i was keeping it in spec. I just kept sanding till everything was on the lower end of spec, and by the time it was, all the scratchs were gone(yay) I also kept putting the cam back in the head and torqing it to spec to check for rough or tight spots in its travel. Eventually it was all scratch free, and i polished all the pieces with my dremel. I am very very happy with my decision to do it on my own. Although if you ever try it proceed with EXTREME caution.

Mike dean--Thank you, i appreciate your kindness. I put 2 more hours on the bike today, and it runs just as it always has(great).:busted:

I am new here, but by not fixing it right the first time if you have a "catastrophic" engine failure it is going to cost you a lot and I mean a LOT more. Good luck I don't wish that to happen to anyone. I am just saying be prepared.

I totally understand why qwik did what he did.
We all do not have disposable amounts of cash we can throw at our bike constantly, I give the man :busted: :moon: , if this would have happend to me my bike would still be sitten in the shed broke. He did what he had to do to ride his bike..If this repair only last 3 months, well that is 3 months he got to ride, if it last one year I would call that success. Get off his ass!!!:p

Right on, glad it worked for you. I actually seized my 4cyl Honda and did a "ghetto" repair and it worked flawlessly for 15,000 miles until the tranny exploded (not related to seizure, chain snapped). and I repair commercial engines that do that on a regular basis.

Well. Im pleased to say that i have a total of 12hrs on the bike since the seizure, and it seems to be ok. I ran it really easy for the first 3 hours, and then i said screw it, and started runnin the piss out of it again. I changed the oil 4 times in the first hour of running it, and found some microscopic metal shavings. I checked the cam journals every 4 hours so far, and everything seems good. The oil is clean, and she runs strong. It's almost tax time so a rebuild is in order now:banana:
