I hate the waiting game.  I have a 3 day holiday weekend starting today, and my bike sits, with parts in boxes, as I wait for other parts to arrive.    :(   With any luck, maybe they'll show up Tuesday and I can at least get the bike back together to ride on Wednesday.

No, unfortunately they did not ship with tracking.  I do know that all I ordered was head gaskets, 2 sets of intake gaskets, 4 head bolts, a few nuts and washers and the exhaust tie rod (the 2 right nuts ((that sounds like a punk rock band lol)) seized on mine and it snapped during dis assembly).   So it can't be in too big of a package and can't weigh much.  Although that doesn't mean anything when you're talking over seas shipping.

I'm just bummed that I almost had the bike dialed in, then BAM!  I have to be honest, it scared the shit out of me when that gasket blew because I was on the throttle hard.  My immediate thought was "Shit!  I just spun a bearing!" but then I realized that it wasn't a "clanking" sound but a "popping".  So I pulled over and looked and was relieved to see the smoke coming out of the head/cylinder seam, because that's an easy fix.  Just would've been nice to get out for a ride on the holiday.  You know, to enjoy myself.  And smile ear to ear every time I make a Hardley Ableson owner jealous.    ;D

Not too excited at the moment, even a little leery.  FINALLY got my parts from Hitchcocks and the head bolts do NOT match what I pulled off the bike.  It appears someone has replaced the stock 5/16" head bolts with what appears to be 3/8" diameter of a different style stud.  The head bolts I pulled off have a short section of course threads that screw into the block and then the entire length of the rest of the bolt has fine threads.  I'm about to run down to Ace Hardware and see if the threads happen to be metric or SAE.    :(

The later Interceptor studs were 3/8" and sometimes people will go to the bigger stud for strength. They may have used them. Tough part is they're a British thread. ERC

Got the bike put back together.  Turns out the head bolts are SAE 3/8".  I'm guessing they are probably for a Harley, but who knows.  It's running really good but seems pretty noisy at the top of the motor.   Not really sure what the deal is, but it did quiet down some after I ran it around the block.  Anyways, took it down the road and it definitely has a little more torque with the new head gaskets and is firing on the first kick.  Definitely a little more compression noticed in the kicker.

How much valve noise do these old twins make?  I noticed chatter before, perhaps it just stuck out more noticeably until the oil got back to the valves?

You probably should take it pretty easy until the engine has gone thru a few thermal cycles and the head is retorqued.

I was taking it easy.  I only got on it once and that was rolling from 4th at about 45mph.  I'm thinking it was just so noisy at first because it was starving for oil.  I'm going to ride it.  At this point, if I have to tear it down again I'm tearing it ALL the way down.  I just need the damn thing to get me thru the summer/fall.  And come to think about it, I almost always wear a helmet, and the few times that I haven't worn a helmet I remember thinking it was noisy then too.

The valve 'clearences' for these machines is supposed to be 'nil', but I usually go for a tiny clearance - say 0.002", just to be safe. More than this will result in more top end noise, also, if the timing chain is too slack, the engine will clatter like a bag of spanners. Excessive end float on the camshafts will also cause noise.

I set the valve lash at .012 which is what the repair manual says the specs are supposed to be.  I thought it seemed a little on the fat side, but .002 seems like it would be too tight.

ERC - What are you seeing your valve lash at?

Scottie, I set them at no clearance with the engine cold. Definitely no more than .002. Also if you've gotten it hot retighten the head bolts while your doing it.  ERC

That must be all the chatter I hear then.  The lifters are too sloppy and slapping around.  I'll readjust them today sometime.  Thanks guys.
