Hi I have a 1916 oztrike and have recently had twin 42 kadrons installed
as well as a new custom made turbo exhaust system, trouble is now iam constantly fowling plugs but only on the one side, i am putting high burning NGK
plugs in but not getting long out of them.
Check your jet sizes and fuel pressure,you will most likely have to change the jetting as it must be running too rich.
The jets have been reduced to the lowest size as i was having more problems flat spots and stalling before they were reduced
needle and seat stuck??
according to my carbie mech Apparently not 
Were the kads torn down, inspected and cleaned before being bolted up ???
Is the fuel pressure OK ??? (you only want like 3 PSI, and yes a standard VW mechanical pump can exceed this)

Was going to suggest you chook them away, and get hotter ones......but I chickened out.
Which NGK's are you running?
kads are only 1.5 -2 psi max
Check the needle and seat isn't blocked! A lot of later model kads are stuck even from new from the factory they aren't right even when they should
be.

As Marcus said, what heat range plug are you using?

The carbs are new and the plugs are NGK- B4H.
