I started with 98" revperf, and last year went back to bored 95". When I first built mine 96" bored was hottly debated. 98" nikalsil was the other option, I would not do nikal sil again, due to the cost to resleave and new pistons was close to new S&S cast iron kit. I am not sure if you can bore S&S .010 over. Some people may not care about any of this.
For me after 50k the nikal sil had marks on the thrust side.
Tearing my 98 down in the fall and riding again next summer, I don't notice a difference. If I got off 98" and jumped on 95" maybe I would. 95" is a tried and true set up. But I realize now there are more options.

98" is the limit unless the crank is changed and once you pull the motor for a stroker kit there are many options for a variety of larger displacment motors which is a simple function of how much money the OP has/wants to spend.
It is possible to build a pretty strong 98" motor (I would not stop at 95") but it takes planning and parts the play well together. I built a 98" motor year before last shooting for 120/120 numbers but missed the mark; had to settle for 115/115. Not saying 120/120 is not possible but if the OP wants more than 115/115 a crank is in his future.
I don't know what the gearing is in the trikes but in addition to increasing displacement, perhaps a gearing change might be worth looking at.
