My next project is to elongate the oil holes on the rockers this weekend. I'll take pics.

All Right , Now I am getting somewhere. Um, I am sure I am not the first on to forget to take out 19-20 bolts on the inside next to the camchain and try and pull off the head wondering why the hell its not budging. Duh.

So my no. 2 exhaust valve seat is not looking good. Unfortunately I cant do anything about it at the moment. Everything else is looking pretty good. Question, Will lapping with the original valve do anything ? Because at the moment its about all I can do. ?? Will a leak down test show me after ?

lapping will only smooth out the mating surface. if there are any big imperfections, more work will be involved.
get some sort of oil pen(see black in pic), or engineers blue marker, and color the mating surface on the head. drop in a valve and spin it with a small amount of fine compound. wipe it off and take a look. the color will remain on any uneven surface.
once you have it lapped well. reassemble the head, prop on one side and fill intake or exh ports with kerosene or minerals spirits, and watch the valve mating surface for moisture.

did those brass shims arrive?

Hope you give'em a heads up that a parcel is coming. Yellow puffy manila envelope.
If you haven't already, get your photobucket acct/app done. Pics will upload automatically. Makes it easy to post them here.

I am sure it came, My mom in law doesn't check the mail very often. I brought my head in and am getting all my valve seats recut and valves refaced. I dont know if 180 bucks is a lot , but the guy's are good and reputable. They will match the valves to the seats and make sure they seal. My wife's gonna kill me but what the hell, its either my bike or a shrink.

Got the head back. WOLF WHISTLE!!! Sweet! It's like brand new. I am psyched. Now only if I can figure out this phone..

bikerbart · « **Reply #60 on:** June 05, 2014, 05:45:45 PM »

I know the order is all wrong , sorry

bikerbart · « **Reply #61 on:** June 05, 2014, 06:30:24 PM »

I think I have an earlier K3 head , as it only has the 2 o rings , 2 dowels and the gasket. My kit has 8 elongated rubber cylinder like seals that I dont think I can use unless I machine the head ?? I know the cycle x kit comes with extra stuff to cover all the years , I just want to be sure.

$180 IS CHEAP!

If you had any resurfacing done, and those knock pins(dowels)....check the depth they sit compared to the surface. If they are too high, they will prevent good mating and compression of the gasket.
brandens leak free top end thread has a great picture of this...

bikerbart · « **Reply #63 on:** June 06, 2014, 09:58:56 AM »

no resurfacing , just a good clean.

bikerbart · « **Reply #64 on:** June 06, 2014, 10:00:46 AM »

total of everything, head and valves came to 220 . Worth it.

bikerbart · « **Reply #65 on:** June 06, 2014, 03:09:48 PM »

Got the shims flybox

, thanks again

Its going real sloooooooow. My arm is real bad still so I can only do a little bit each day. Sigh. I haven't felt this sh*tty since I had full blown sarcoidosis. Carbs are all done. Just need to get a few things like high temp thread sealer and copper gasket spray.

iron_worker · « **Reply #67 on:** June 08, 2014, 11:40:01 AM »

I don't think I would want to leave that head gasket surface as a blasted surface. Should be surfaced properly and be quite smooth for a proper seal.

Yes. I watched a dude do it on a piece of glass with a lapping compound once. (It was 20 yrs ago, so , I think it was lapping stuff ??) I have nothing but time as I cant ride anyway. Its my next step.

I am a little confused about the valve adjustment and cam sprocket. One manual says to turn 360 degrees and another says turn 180 . I put on my cam with 1-4 at TDC with the keyed notch at about 12 o clock, I should be able to do 4 adjustments at this point then turn 360 and do another 4. This does not work. Another manual says do the tappets that the lobes are closed turn 180 do the others and continue til done. This makes more sense to me and this way works. What am I doing wrong ? Or am I ? Do I turn at 180 intervals and do 2 valves at a time 4 times or 360 degree intervals and do 4 at a time

?? does this make sense ?

Yes, this was the easiest for me. Adjuster screws all the way out. 4 at a time, then rotate 360. Hondaman's book outlines this very well.

I dont know why this got the best of me. Duh .

bikerbart · « **Reply #72 on:** June 25, 2014, 09:05:56 PM »

So after all my questions and worrying. I just went out to my bike, checked the valves , and, they were all spot on. I think my problem is i double and triple check my work, and after a coupla beers, well , you know. I got confused , er , stupid.

bikerbart · « **Reply #73 on:** July 17, 2014, 07:28:54 AM »

Its been a while . I finally put it together , and , It runs fantastic. fired right up on first kick . Runs like a sewing machine , after rebuilding the carbs and syncing them with gauges , holy crap , its almost like new. No chatter, sputter, or anything. Now its time to ride it. I put the 4-2 's on it , nice and mellow. The small peashooters are too loud so I put the megaphones bck on. I dont like the straight look of the peashooters , so I am getting upturned adapters for em.
