G'day yumzswm. Sounds like it could be time to put a mayday call out to Max Oradea . He's a very knowledgeable sort of bloke on the Venox ... if fact, hang about, I'll put the call out now for you right now mate.

I am sorry to respond so late!
How many miles on the bikes? the cylinders should last at least 100,000km+ with proper maintenance. are the plugs correct andnot fouled? it really sounds unlikely that 2 bikes have rear cylinder issues. are both bikes have sufficient coolant level?

[Hairy Bob]

Hey yumz ... I'm no expert, but I've got agree with Max, that it IS too coincidental that two bikes would be doing exactly the same thing ! As Max suggested .. try the basic stuff first like new plugs.

Yep agreed with max and bob check sparkies and also get someone to check your valves

[Hairy Bob]

Hey yumz ... any luck yet or what ?  Err .. with the bike I mean 😊

I was thinking check the valve adjustments. Comma is on the lower row of your keyboard just to the right of the M. (Hard to see with my rapidly aging eyes!)
