My FXDWG has a 95 now (No headwork). I suspect a 103 is not a lot different without heads. The torque/Hp curves from HD show minimal differences. I am going 103 with ported heads, pistons, 45mm Carb, etc. The package I have picked out is reported to have 120 hp & 115 Tq at rear wheel, mostly because of the Heads, etc. I was considering going with the 95 & heads, but knew in a years time, I would never be satisfied. Anyway, I will give you the "seat of the pants" report in the spring!bulldog2 said:Traded my 03 night train in on a new street glide, vivid black with tour pack and 103cu" won't be in untill march, going to be a long winter!! anybody have any opinions on the differents between the 95cu" and the 103cu", iv riden the 95" but not the 103" iv heard there is a big difference between the 88" and the 95" but not a big difference between the 95" and the 103" any truth to this ??
