Tools for valve adjustment

Night #1

I had a few hours to get started on some stuff tonight. Removing the gas tank consumed most of that time

I had to syphon a good bit of gas out of the tank... my burps taste like premium

The other bit went all over me and the floor... Stupid fuel lines took forever to get off

Not a good start

I'm also pretty pissed at how bad the paint is on the engine cases. It's pathetic and annoys me in the worst way possible.

Night #2

Had even less time tonight but still managed to get some stuff done.

Removed the airbox and battery and all things around it.

Still haven't touched the TBs.

Sure as hell a tight fit to the vertical exhaust valves with the suspension linkage right there.

How do you guys do it?

... Stupid fuel lines took forever to get off...

Cut both the feed- and return fuel lines and insert brass quick disconnects (I got mine from Omega.com -- a search will turn up the part numbers).

Here they are (metal with shut-off valves on both halves):
FT-LCD170-05: $24 (5/16" ID hose barb, In-line, 2.00" Length, Shutoff, Coupling body 1/4" flow);
FT-LCD220-05: $15 (5/16" ID, Hose barb, Straights, 1.85" LCD Length, Shutoff, Insert 1/4" flow).

Insert the quick disconnects in opposite directions so you don't mix up the two lines.

Who can tell me what this is?

There wasn't a fuel line attached to the rear barber outlet when I removed the tank.

Better yet... does it need a line and where should I run it?

That is the fuel pressure regulator.  The empty port references local atmospheric pressure.  No need to connect it anywhere.

Molto bene!

Update

Clearances are as follows.....

Horizontal Intake

LO- .0035     LC- .0065
RO- .005      RC- .006

Horizontal Exhaust

LO- .003      LC- .008
RO- .004      RC- .008

So.... what do you more experienced people say? I was gonna shoot for the LT Snyder specs but I will gladly listen to anyone else's arguments.

LT Specs

Intake

Opener .004
Closer  .004

Exhaust

Opener .006
Closer  .004

I pulled an opening rocker pin tonight just to get a feel for it. When I put it back in for the night, air got trapped behind it. Is this bad or will it not effect anything? LT Snyder manual says to scribe a line down the pin to allow the air to run out. All is fine and dandy but hot damn I'd have a hard time taking a dye grinder to my rocker pins.

I'm also getting a little anxious now. Bikes been apart for a while and I'm hoping that my pictures will get it back together. Otherwise, I'm going to be posting a lot more pictures and asking a lot more questions.

IO .004-.006
EO .006-.007

IC .002-.004
EC .002-.004

Don't worry about the air behind the rocker pin.

A few observations....

Horizontal rocker pin cover on the right side has some gouging. Looks like a closer pin backed it's way out and is doing a number on the plate.

Oh and I seem to have discovered 5 flaking rockers... I'm pretty pissed 



Would that have effected my measurements in any way when I was checking my clearances?

I'm so make the beast with two backsing pissed that I have to yank 2 closing rockers. Those springs look like a pregnant dog to get back in with the heads still on the bike.

Sorry to see your flaking rocker, and hearing it's got partners. 

Clearance measurement associated with a flaked rocker is FUBAR.
IE, the opener clearance you measured on the valve with *that* rocker is worthless, other than the practice you got...
Doesn't really matter in the long run, as you'll have to re-do the measurement with the replacement/reconditioned rockers anyway.

Were the flaked closers paired up with flaking openers?

Yes, the springs are a pregnant dog to get back in.
Which closers are you replacing?
If they're intakes, you have to undo the exhaust closer spring on the same side, as it sits on the post inboard.

Mmmm...vertical exhaust closer.
That one's fun.


Don't despair.

[lazylightnin717]

Mmmm...vertical exhaust closer.
That one's fun.

I guess I will see soon enough

Tomorrow is going to be a good day

[Speeddog]

That green bin full'o'shims will come in handy.   

I like the paint brush too. 

So.... you pulled the head off.
