Being new to the MV hobby I've spent a couple of hours digging through the search archives and found some neat threads. But, nothing that have me what I was looking for. I know the CTIS can be bypassed by placing Schrader valves in the outboard side of the wheel? However the 923a2 I'm currently looking at does not have the CTIS provisions on the wheels and upon asking the seller about this he informed me that he wasn't sure why but that the wheels were swapped out with A1 wheels before he got it. So my question is. Is it easy enough to find the correct wheels or are they the same between the A1 and A2 and all I will need is the wheel parts for the system? Or will I need to check all the lines and valves from the hub inward?
