Thanks for the great feedback guys, your comments were very helpfull,

I checked the dipstick on the front dip & nothing showed, I've added 4 Litre's of TX oil & I now have movement. Just wondering how much oil the front diff holds.

Also.. how do I check the hydraulic fluid & what is the max fork height, as I have read comments that the CY50 lifts to 4Metres, but this one definately dosn't go that far.

It appears the chain is at full runout & the Ram is at or close to full extension ( unless there is another inner ram that is not extending due to low hydraulic oil.
