Would like opinions, advise, and pros cons of aftermarket engines... Such as Ultima, rev tech and S&S engines... Basically for reliability and power differences.
Thanks,
Nate

 

All mine were evo but I had good results with the newer 100 inch revtech and flogged 2 127 ultimas. They dont put out the hp they state but have a truckload of tourque. I got 120 tq out of my 127 fxr

 

S&S.

Most reliable? S&S hands down.

 

S&S Without a doubt

S&S without a doubt

 

As a customer I have only bought one aftermarket engine and that is an S&S. It came with a 3-year warranty, which I haven't needed to use, what seems to me to be the best after-sales support (again haven't needed!) and once run in delivered slightly better performance on the dyno than S&S claimed for it. It took a while to run in but smoothed out and now runs like a dream. I changed from true-duals to a 2-into-1 which has made it a far smoother ride, as well as delivering increased low/mid range torque.
