I'm in the process of getting my machine to return a charge to the battery

I have had a slight setback on my machine,   I noticed a slight oil weep on the front left cyl. head
 so I undid all bolts (in sequence) and went to re torque the head to 25 ft. lbs.
upon torqueing up the top left exs.bolt I stripped the threads "ouch"
 so head & barrel off I discover a 3mm gouge at least 1 mm deep & about an inch long this was below the rings so I did not see this when the head was off
so I have now bit the bullet and purchased a new cylinder/piston kit as this was very close in price to having a time sert  and 2X new liners + pistons
I am not sure how to stagger the rings when I re fit the new pistons, I read in the manual (not Haynes) just space the rings 120 deg. apart where do I start with the ring gap from the top ( compression ring)  ?

I had left the oil poured down the rockers (exhaust./inlet) overnight,   so this morning I removed the return pipe and placed it as low as I could & gave it "50+ prime kicks" ign. off

upon start up I placed my thumb over the end of the return pipe and felt a bit of pressure removing my thumb I get an eyeful of 20/50 but even better a steady hiccup of oil from the engine

reconnected the return pipe and starting up I now have a constant hic hic hic of return oil to the tank

thank you all for your input "very relived of Criccieth"

thanks for the reply mini me I will do the rocker tip this morning, am I right in thinking that if I'm getting no oil return then the oil is not circulating around the engine at all ? I just don't want to risk any damage to it .

I have just started my T 100 after a 5 month lay off repainting frame new rims/spokes etc

 it went second kick no problem but I cannot see the oil returning to the tank,

I removed the return pipe and forced oil down it till it was coming out of the end another quick start and still no oil return ?

engine wise before the strip down it ran fine ,I have changed both oil feed pipes and rocker feed pipe for new items with fresh new oil

 and replaced the valve springs nothing else was touched engine wise I hope someone can help me out with this serious problem

thanks for the input Mark there is no choke fitted , the carb is a very new looking (shiny) Wassel I have removed it and blown it through very thoroughly all is very new looking inside and no debris was found
I checked the points gap (using dial gauge) and the setting was spot on points opening at 38* BTDC and a gap of 15 thou. at highest cam point
I started to check the electrics starting with battery pos. to main loom and could not get a reading
  from pos. to neg. via the battery which has a fuse inline on the pos.
 side still no reading from pos .earth to the battery neg. terminal nothing I could see the fuse strip was intact however when I took the fuse out of its holder it just disintegrated in my hand although it seemed brand new
so a new fuse fitted and it started with no hesitation
I have yet to try the bike on the road so I will post my findings.

Does anyone own or have experience of the above bike as I have just bought one, it starts fine and runs very smoothly at low revs when accelerating 15mph + the motor seems to die and not respond to throttle position
 when I shut off and come down to under 15 mph it all feels normal ? could I have an electrical breakdown or short maybe  ?
