Well, after looking at a finished Pro Port chamber, I guess Bruce's question/concern was legit, huh. The plug location has clearly been moved towards the center of the bore/biased towards EXH. Now, what effect this will have on a running engine has yet to be seen.
I know other brands use this design as well. What are some pros and cons to this update?
