O'rings for throttle shaft

I only loaded one spring. Idiot. Slow down.

 

I have everything back together. Still won't start. Might my needles be bad? Seems like it isn't getting gas.

 

It's not likely to be a problem with the needles.
Take a break for a few days and come back to her with fresh eyes. Don't even think about the bike while you're on that break.

 

I'm on vacation right now and I want to ride! How can I not think about it. Still going to keep trying. Seems to try to start when it's not on the center stand.

 

Revisit fuel flow and confirm your wet float levels.

 

Pretty sure I have them in spec. Can someone look at the attachment and let me know.

 

Looks to be about 2 mm below seam. What bike do you have? Looks like Hitachi carbs and probably should be +/- 1 mm.

 

650 Maxim 1982

 

NOTE: all of the following models used HSC32 carbs:
XJ650 Maxim, Midnight Maxim, XJ650RJ Seca (non-turbo), XJ650 Euro all use HSC32 carbs (various versions)
XJ750 all USA 1981-83 models use HSC32 version 5G200 (Seca) and 15R00 (Maxim and Midnight Maxim)
XJ750 all Canadian 1981-83 models use HSC32 version 5H200 (Seca) and 15T00 (Maxim and Midnight Maxim)
XJ750 UK/Europe 11M models, XJ750 Police models 24L and 37H use HSC32 version 5N100

-Fuel level measured via the clear-tube gauge: 3mm +/- 1mm (.12 +/- .04 inches)

Looks like you should be ok in this case.

 

That's what I thought. Just not sure why it won't start.

 

Have you primed the carbs and ensured that fuel is flowing to them?
The first fill after being dry can cause an air bubble to block flow into the bowls.
Crack the drain screws to be sure each bowl is getting fuel.

 

I'm using an auxiliary tank right now because I know I will need to make some adjustments. Would I have to crack the screws if I just checked the levels? I did that with the carbs off the bike. I didn't drain them before reinstalling them.

 

with drain screw open do what you did then lower the tube to recheck. tube will refill to fuel level and yes you need a fuel supply hooked up when you wet set test.

 

Rechecked again. Filled the bowls and let it sit for a few minutes. With the auxiliary tank connected, open the drain screws to make sure fuel was flowing, closed the screws. Connected the clear hose and opened the screws and checked levels. All sit as in the picture. Going to reconnect the carbs and see what happens.

 

How does that song go, can't start a fire without a spark? Decided to check the spark off the plugs, and nothing on 2 and 3. Coil? Recently changed the plug caps, and they are tightly on.

 

ohm out coil to see if the caps are making connection to the wires

 

Nothing going to caps on either side, which is strange because I had spark on 1&4 the other night. At coil 1&4 2.9, 2&3 2.6

 

what reading do you get from plug wire 1 and 4 , then plug wire 2 and 3?

 

Nothing from either 1&4 and 2&3. Should I take the caps off and check? They are brand new.

 

don't know if this should be a cable tv comedy or a docudrama

 

Learning as I go

 

with caps installed you are looking for 21K ohms make sure meter is in correct range .

if above fails unscrew caps and re test.

 

With caps installed, no reading. With caps off, no reading. I did cut the wire back a bit again, just to make sure I had good connection. Noticed that the 1 wire had a bit of corrosion (blue) inside. But I did have spark from that wire the other night.

 

corrosion is the issue , it will keep caps from making contact when you screw them on. use a little silicon on the insulation

 

Is it possible to replace the wires from the coils to the caps?

 

I did, but still nothing.

 

Yes, but not so easily.

You can cut them short and splice in new (NGK has splices)
ignition-wires.112190
or...
Spark plug wires

Or new coils from Chacal.

 

Or fit Honda CB 750 coils.

 

Just confused as to how I was using a color tune last week, and now I have bad coils or wires. I guess my option is to splice wires on a 38 year old coil, or replace the coils.

 

Coils work right up until they don't.

One thing to do before jumping to replace them is to try and start the bike in the dark. Have a spray bottle of water handy too.
Look for sparks jumping to ground, which is an indication of insulation that has failed (this can happen at the coil body or at the wires).
A mist of water before the test will make it easier for the pixies to find ground.

Also double check that the primary side of each coil is plugged in with a clean connection, and that there is continuity to the TCI.

 

I decided to check the spark on all 4 again after trimming back the wires last night. Tried a spare plug on all 4, and they all had spark. Took out plug 2, and it was all carboned up. Changed it out and cleaned it and moved to 3. Did the same thing because the plug was the same. Moved to 4 and tested the cleaned plug and the bike almost started. Changed the plug, turned it over and it started right away. WTF?

 

Even new plugs can be bad. I'd still check the insulation. You may have moved a wire just enough that it can't jump a spark to ground until it hits the plug.

 

ebay has ngk type splices comes with plug wire working well for me

not what i got but look like the same thing 2 splices and 3 feet of wire per kit

if i were blessed with your luck, i'd just buy some honda 750 coils and a set of plugs and be done with it

 

Thanks for the words of encouragement. Lmao.

 

From someone who has given me so much advice, would you splice or replace?

 

I would splice first leave enough plug wire to be able to splice a few more times. then consider new coils

 

While I'm waiting for the splice kit to arrive, is it of any use to try and sync or color tune?
