I have 2,000 miles on my 2012 Street Glide with this kit. No problems so far, pulls great. I had mine installed at time of delivery, so the dealer is honoring the factory warranty. There is another Street Legal Stage IVthat maintained the warranty but it doesn't include the SE Race Tuner. I have heard others say that they have had mechanical issues with such kits once they get over 18,000 miles on them. I'm keeping my fingers crossed and enjoying the ride for now.

 

what mechanical issues are they having

 

i have pieced together stage 2 and mva heads 10.5;1 pistions. my original 255 cams produce way too much compression and have a ccp over 212. good number to be at is about 180. much smoother. new cam andrews 32 more suited fro 10.5 and higher cpmpression and can feel the difference in combustion already the pop feeling i feel every time it fires is gone.
dont trust the counter guys when looking at parts catalogs. the cams in the stage 4 will match st new heads . most of these counter guys have no idea, one suggested the 54 andrews just by reading the descriptiuon. get a good engine builder, not just a mechanic, a guy who builds drag racing engines that understands head cc volume, pistion cc dipslcedment ccp values.
the stage 4 kit is matched for parts u get but if u want to make changes u will be limited later to compression ratio. also keep in mind pinging, higher compression is more likely to pinging. friend of mine had this builder reworked heads and get a better flow and better flow velocity through the head than se heads. he buikd his 103 kept flat top pistons, reworked heads rework throttle body changed to andrews 54 cam exhaust and new filter and got 120 hp and torque
wish i woukld have gone to see this guy before i pieced 2 kits together.
i have done all the installation my self and just used the builder to modify all my parts

 

Why not just go with a 120r at that point?You may want to look at he price difference between the 2 options.just my 2 cents.

saw a post in here a while back where a guy did the 120 route it blew up after a cpl thousand mile they wouldnt warrenty it saying its a race motor
u can get 120 hp with builder going work for 5-6 grand youo will spend more than that on a 120.

 

I just installed and tuned this kit for a customer on a 2012 FLHTK and I also added the screamin' eagle heads to it as well. It ran smooth (like everything I tune ) but in my opinion, these cams come on much too late for a bagger. The exhaust used were V&H power duals with monster rounds and the AC was also a screamin' eagle (stage 1). You won't come onto cam until at least up around 32-3400 with the SE-259e's. Just way too much cams for me personally but they do pull pretty good after that. The final numbers on 4th gear pull at 100% throttle were 97 HP @ 5620 rpm and 109 TQ @ 3800 rpm. I can post a dyno sheet if anyone really wants to see it.

 

103 mva heads 10.5;1 pistons 255 cam ( out of bike now) vance hines power duels monster rounds got 98 hp 107 torque but ccp was way too high cams not suited for high compression just put andrews 32 in it havent tuned it yet .
