What a day swopped oil lines
then put me boot on lots of flames but one side then other couple of bangs
3 hours same injected some fuel in cylinders nothing got a massize spark nearly gave me cardiac arrest so fuel flames spark has to be timing?
but spent some time thinking i was a ok or 180 out
only other thing is i spent yesterday injecting oil all around wrong way but shouldn't be problem? breather dripping a little?

Pretty sure i found the problem
i set up points at 38 at the end of the cam portion on ring not at start(must have been late in the day!) points would break another half a revolution around
thats why i had flames out the carb?
Recheck all again today.

yep, getting everything dialled in is a chore. I would say don't make the mistake i've made of running the motor too long if it's running lean, it gets dang unhealthy hot even without pinking.

I really like what you've done . Dont let the dialing in part get in your head sometimes I have to step back and get a new perspective on the situation and in my case take the beer goggles off .

I have established bike is running to lean on pilot jet circuit ,bike has difficulty idling, mixture screw nearly all way out,and cupping hands over carbs can get a steady idle,but went on the road a few times and once past 1/4 throttle accelerates away so maybe main jet is fine (but that is later)
I was amazed at how loose everything got on this engine cylinder base nuts got a full turn on them(but some of this is due to paint settling ) Head gasket started to blow studs had about 9lb on them
torqued it all up again and is good to go (this didn't help jetting process )
today i go up a size on pilot if i can find one.

Spent most the morning riding around to find keihin pilot jets.Did all motocross shops and Vespa/piaggio(polini bore kits run pwk carbs) got 2 40s up from 38s now bike is a lot better but mixture screw is 3/4 turn out at optimum fast idle, so tomorrow i go to 42 (i borrowed jets from ktm dealer and said id be back to pay or swop he said 'Prego'!translation;your welcome) I'm aiming for 1 1/2 turns out with correct idle and no surging etc then its throttle chops etc.
Crankcase Breather still spitting gearbox pissing oil (probably seal on drive side) so plenty of little jobs to do

Im sure you re adjusted the valve lash after retorquing everything.

Can the needle in the slide be adjusted up and down? That seems to have a big affect on low speed operation as well.

I do that all the time . I remember while I'm doing it I'm on the wrong lobe and then next time I start doing it again! Really great build inspires me on mine.

Yes adjusted valves, needle will go up and down but stay in centre clip for the moment .Pilot 42 today but now 1 turn out so 44 next if i can find(otherwise is order off internet or Keihin Napoli but thats a little epic) still if i cup hands over stacks i can bring down to steady idle, so we need more fuel less air

dialing in is such a pain. Jetting aside, trying not to annoy your neighbors and finding an open spot to wide open throttle can be difficult.
