Thanks. im about 2mm out on the disc side, looking for a washer to try!.
The gasser wheel is off a Pro 04. Tried a 3mm washer but that pushes the disc into the left hand side of the calliper. ( with original 4rt wheel spacers when the wheel is tightend, the disc touches the right hand side of calliper)
The gasser wheel is a spare we have. And it will save having to buy a new mont wheel if i can get it to fit, Im sick of changing tyres for practising.
P.S.
Anyone want to buy 250 Pro 04. Mint.
