• full alloy pullstart
• genuine Zocchi exhaust
• Carbon Fibre reeds
• Zhongya slicks (2 front tyres one on the rear)
• full alloy brake levers
• 2 piece head kit
• Heck of alot of compression

Tubeless tyres need a big rush of air to push the bead on to the rim. You won't get that without an air compressor.

if they are tubless tyres u need to seal the bead (around the edge) of the tyre to the rim

a compressor should do it no probs if not you can punch the top of the tyre a few times it may help them seal, a little soap & water around the inner edge might help it seal & slip on better

if its a tubless valve it may be leaking u will need to replace it
or the bead of the tyre may be damaged this will cause a leak.

another thing tubless tyres dont alwayse work on chinese rims, the casting may be pourous or just rough as guts & will leak,
.. a easy fix is to paint the inside of the rim with rubber or a latex sealant , or a few coats of paint

if they have tubes the valve may have moved if you rode the bike when it was almost flat & tore the valve from the tube

ok i will do it a dads on the week end so around 60 psi? so fiil it to 60 psi than leave it or deflate it straight away than do it again?
