“Choke your transfers down for your next heat you will love it” …..New Gpx Green has 7 PORT liner plus a special extra liner from aluminium fixed inside The crankcase to adjust fuel flow in transfer ports. The aluminium liner must not be removed it is fixed in and the new motors have smaller cooling jackets.
So, CMB's offering a standalone 91 GPX now, or just the GPX kit?....New CMB 91 GPX 7 port M line replacment and RS.3 Evo replacment

Ok, now it all makes sense...last looked at CMB's site a couple of weeks ago and didn't see anything about the M-Line/GPX connection.As far as I know the GPX TUNING KIT fits the M line case. The new GPX 91 Engine has a different diameter Brass liner. To fit the new case.
I will check with Mauro for a definitive answer
The GPX kit fits older Evo Motors and the new RS.3 cases.
The latest GPX liner in the green motor has a smaller diameter of to match the pressed in aluminium liner
I got excited for a second, but looking closely looks like there is a pretty bad mismatch between the case and the aluminum liner. Look at the transfer port below the exhaust side eyebrow. Do you know of the aluminum sleeve can be removed?The GPX kit fits older Evo Motors and the new RS.3 cases.
