Sounds like you have the vacuum pipe incorrectly connected - you are able to run for a while on the fuel in the flat bowl and lines, but then it runs out.
check the vacuum line to fuel tank vacuum switch and make sure it is working.
The other thing to check is the fuel tank breather - run with the tank cap cracked open and see if the problem goes away - if it does, the breather pipe is snagged.

What is the sizes on new & worn rings on Bajaj RE205 Piston

the size of the ring will be determined by the bore size
so if it is a 3"(75mm) bore the ring will be that size if placed in the bore separate to the piston and pushed square and to the bottom of the bore the ring gap will denote if standard , worn or oversize to standard
new rings in new bores will have a ring gap of around .010"
worn rings will have a larger gap up to .040" and will have sharp edges where the ring lands wear the rings
over size rings in standard bore probably won't even fit in the bore to start with
ring sets are bought in standard size , .010" over size,.020" oversize,.030" oversize,.040" oversize with the oversize equalling the final hone of a machine bore
so if the machine shop bores the cylinder out to .020" oversize then you need .020" oversize rings to maintain the correct ring gap
from experience I have found that if I follow that rule , on measuring the ring gap at the bottom of the bore the ring gap is about .015" or half worn out
I counter this by getting the next size ring .030" and filing the ends of the rings at the gap to obtain the .010" gap This has produced better longer lasting repairs

How do i no if i need my pisyon cylinder re-board or just cleaned as there is some light scratching in it ,and if i do need to grt it re-board what size will i re-boar it too. thanks for your help

The bore has to be measured at a number of places to see if it is out of round 0.01mm or tapered 0.05mm
You will need to take it to an engineering shop that can do the boring, they can measure the piston and bore to determine what oversize it will need.
with only light scratches probably 1 oversize 0.25mm, if it has been bored before the oversize is stamped on the top of the piston. 0.25, 0.50, 0.75
A rough measurement can be done with a feeler gauge, between the piston skirt and bore.
piston clearance for a 125 is about 0.055-0.060mm with a limit of 0.1mm

Dear Sir, can a gl1000 be re,bored & fitted with

Yes it can be bored, .050 over is fairly common on this bike. Before boring the cylinders, the new pistons should always be matched to the old ones. You always find problems with aftermarket parts. Have the cylinders bored to match the new pistons. Don't bore the cylinders and expect the new pistons to be a perfect match. I hope this helps.

I want to know how big i can bore out my 125cc 4 stroke motorbike

I believe the pistons only range from stock to 1st oversize. Boring to first oversize will not make a noticeable change in performance. If you want a real change what you need is a race cam. You will be able to wax any other 125cc and many 150cc bikes. Below is a source.

My cylinder got gouged by the piston. Can I bore

It depends on how deep the gouge is. Having it bored and a new oversized piston may set you back more than a new stock piston and cylinder.
