I'm trying to get the o-ring into the rocker arm cover and it's a tight so it slips out one side, fix that, comes out the other side. That went on for half an hour before I had enough. Any suggestions to get this to work? Boil it to heat it up and have a little more stretch? glue it in? Any suggestions welcomed.

Got the read flag for not posting in 30 days, lol.

No pics but finally after a couple of wiring issues and other time constraining setbacks. (aka other builds), I've got her to almost running  condition.

Tried to ignite her for the first time since a complete tear down and rebuild. A little cursing and swearing, some quick start and she kicked off into life. Wouldn't run without quick start at first because I didn't have the airbox or filter on, but as soon as I cover inlet for the intake manifold with my hand she stayed alive and running. Now the heads have been ported and polished and the bike is running a 4-1 exhaust, my question is if it's only runs with air restriction does this mean I need to adjust the jets for bigger?

2nd problem - as soon as I turn the key in the ignition is seems to drain the battery and doesn't have enough juice to crank the starter. Any info would be greatly appreciated.

I want to say yes, you'll need bigger jets.

As far as the battery goes, is the battery on it's last leg? Or maybe there's a short somewhere that is sucking up all the juice.

Either way, glad to hear you're back at it.

cool Rich, thanks for the backup, sometimes when you've been working on something for a long time it's nice to know your thinking is on track.

As for the battery it isn't 100% so a new battery is in the works.

I'll post some pics soon.

so just a bit of an update carbs have been off-on-off-on-off-on. I'm a master at getting those bastard bank of carbs off and on that bike. 

Carbs were leaking, had the floats adjusted wrong, back on and now only one bowl is still leaking out the overflow. But I'm suspecting a sticky float. so it'll be back off again. 2 days ago the bike was running on its own, albiet still with the choke on halfway, make the adjustment to the floats to stop fuel from overflowing and yesterday no running starts but dies  >:( . Four carbs are a bitch to work on. Anyhoo, we're making progress. Slowly.

Here's a quick pictoral tutorial on how I did my cables.

Cold chisel worked the best for a sharp clean edge on the cables. I used it on the housing as well. I removed a section of the plastic  outer wrap on the housing then at split in the metal, that's where I put the chisel. No pic of that sorry.



A view through the end. I pushed an awl to spread the wire open so the solder will flow through everything.



Fluxed the hell out of it.



The solder I used. Bought from Canadian Tire




The finished ends. The larger end is actually brass wire wound around the smooth end of a drill bit that gave me the correct diameter that was needed. A little filling and tada instant cable end.




I need focus, seems my stable is full of steeds that need my attention.

Nice, we have a 425L we're turning into a military-themed little town bobber. Let me know if you ever get tired of looking at it. :)

It's my pet project, I'm just getting it ready to sell. I'm located near Toronto if you're interested.
