Went to get this project started today....
Carbs a mess and points way off. Not proper workspace so setting points innthe dark wasnt fun. I think ingot 1-4 right got to try 2-3 tomorrow.
Also i set all the carbs at 1.5 turns out. If i remember cofrect that is the air control screw?

Posted for help here on the forum. Was told most likely bad condenser on 2-3. Got that in the mail yesterday just waiting to have time to put it on. Working over a bunch (voluntold) amd about to have a new baby so time is limited.
Also got my extended cables pod filters (didnt get a airbox with this bike) came in.

It lives!
Replaced condenser on the 2-3 side and out new plug in.
It started 3rd kick
After the intial kick it fired on first with the choke shut.
On 3 cylinders. No fuel to #2.

Next thing to mess with. Carbs.
I'll try to remember to post pics of the pligs i pulled out tomorrow. They where gapped to .45!

I understand if you want higher bars for a chopper (to come) but those look pretty rough (like they are cut off a wrought-iron fence) and the spikes are dated in a 90s way.  Maybe something either more modern or more oldschool, but either way more refined??  Just my $0.02 for what it's worth.

Honestly the biggest reason im running those bars isnthatbthey were made my my freind who taught me to work on bikes. So i figured as tribute to him I'd run the set he made for a really low budget chop he did.
Originally i was going to run some CZ bars

Got it firing on all 4 tonight. Carb wasnt getting gas through the needle valve. Still not firing right but smoothed outbthe idle enough to listen to it sound decent. Tomorrow after my 12 I'll try to see what its not firing as hot as the others.
Also found out the PO installed new jets 100 mains and 40 pilots.

How about the front forks?

Maybe front braking system too?

You planning on selling these items?

If it sounds like I know what I'm talking about, it's because I cut and pasted from someone else.

Figured out my clutch today. PO had the bolts way too tight and mismatched clutch springs. Ready to add oil and test ride now.

Went to start the 500 th other day and the finicky ignition went out and after i wired a switch in it quit firing. Old harness has its gremlins. So looks like a re wire in store. Basic harness HondaChopper style.
Baby was born week amd a half ago amd started moving a week ago.  Beem a busy week just getting a workspace set up and settled in.
Workspaceos a 8×14 building with a 200amp service box already there and hot. I've got some 4ft T8 fluorescent light assemblies and LED bulbs to like the place up to be wired in this week.
