My buddy with an 08 SE Ultra was quoted $11k for parts and labor to do a 120R swap...That was at Gulfcoast HD in New Port Richey Florida...So I told him that was like close to 4 grand in labor! Told him I want that job! Won't cost no 4 g's for labor either....unreal..

I would like to know if anyone here has installed the 120ST, their thoughts and what are some of my other options besides the stage 5 tire shredder. I do some long distance riding, about 8-12 hours in a day, but do most of my riding around town, bar hopping. I want to go fast, but I also want reliability. I understand that the two do not go hand in hand, but would like a happy balance.

After hearing what 1BMF went through, I do plan on sticking with what "they" want to keep a warranty, but I usually do my own work and have done many of minor upgrades such as air/exhaust/cams to both my Evos and Twin Cams. It will still be a few months before I move forward with my venture and plan on starting a thread to document it.

I didn't want to high jack the thread, but it has been dead for quite some time and wanted to get people back to talking about the 120ST.

Thanks,
SWLAMedic
The 120st sounds good with 1 year warranty but I would be worried about the crank... It is a shame they don't run a similar crank set up as S&S. I am not sure if they have the same runout tolerance as the 103cu but 12 thou is brutal! I think 2 thou is max for gear driven cams.

Sorry to hear. It's always a risk to warranty if you use parts or tuner or tuning away from the warranty provider. I would get a calibration of the tune and compare it to a tune the dealer would have supplied or loaded if possible. This may assist in determining if your external tune was relevant to the engine failure or not. Ie if both tunes are similar it may have failed even if you used the se tune
