No flow?

[Guest]

I'm new to fuel delivery...
So this is a rookie question, like most of mine.

Just did a valve lash on the 1100. This was the first time I had actually disconnected the tank (had only moved it back/up before).

Got everything put back together, and I'm 99% confident it went back together correctly. Now it won't fire.

Ran beautifully before.

Yes, I have the dreaded 1980 petcock.

Yes, I tried prime.

Should I just wait for some fuel to flow on prime?

HELP!!! 1400 mile trip in 6 days...

You have to suck on the vacuum line to start the prime flowing. Once itstarts it will flow forever.

Ok - I'll try it.

It backfired into the airbox something fierce - is that normal?

[tkent02]

No .

Is yout timing 180 out or somethng like that? Wires going to the wrong plugs?

I don't know. Could that happen during a by-the-book valve adjustment?

I spun the crank on the right side of the bike (rider's view). Only spun it enough to align cam notches as necessary.

From my work on old crappy cars, it does smell like a timing issue.

Spark plug wires crossed?

Wires on correct plugs. They're twice labeled, and confirmed.

It's crazy. I just replaced the valve cover gasket a month or so back - basically the same procedure, except the valve adjustment. I followed the procedure on Basscliff's site to the letter (I think).

Bike started instantly and ran great before - was only adjusting the valves because everyone says to do it.

Ugh.

Someone else said maybe it was flooded. So I pulled the plugs. #1 & #2 were soaked - #3 & #4 less so. Torched the gas off, and turned the engine over 25 times or so without the tank hooked up.

Waited 15 minutes or so, put it back together, and same result. 1&2 wet, 3&4 pretty dry.



(yes, I checked spark)

Can spinning the crank to line up the cam notches screw up the timing?

check fire...don't catch on fire if fuel is around.
and no to the above question you asked.
it is easy to pull harness/coil feed wires loose..lose the orange/white connection and you have no spark.
when dragging the VC out things can move around or come loose.
hopefully you rally cranked down those little nuts...they take some force to not come loose after a few miles.

ok just seen you added that you checked spark...on all 4 i assume?
did you remove you plugs to adjust your valves?
i ask because you can damage the advancer when turning the 19mm nut if there is much force involved.
if damaged this could have your timing off.
just a thought...

I did not remove plugs to turn crank. I didn't meet much resistance.

So what's the fix for what I could've done?

Plan B is in place.
