Completed prostreet project. 127 Ultima, 6 speed, electric shifter. Goes like a raped ape. I already posted a thread under softails but thought you guys would like to see it.
You have a good idea with the 127".Until I first tried out a 155" it was hard to imagine.Last year was mainly breakin and getting the bugs out,really looking forward to this season.Other than remembering the torque hit, in the first couple of gears,and staying on the seat,it is a white knuckle ride.My other bike has a 124",pushing 130+ lb ft,.The 155" makes 140 lb ft at 2500 rpm,you know what I'm saying.Dog

Actually I do. Surprisingly, myUltima 127 advertises similar numbers. They claim 140 HP and 145 torque at the wheel. One note they have in their claim is that these numbers were made with a Mikuni HSR48. Mine came with the slightly smaller HSR45 so I may have a little less, but I also have an unbaffled 2 into 1 and a velocity stack and I'm using slightly larger than stock jets, so, I may actually be close to those numbers. Although Ultima's are known for their high HP so I'm not that surprised. This thing pulls like a freight train.
