Ok, now you all have me asking why stay away from the TP top ends? I guess I could do a search? Hmmmmm......... Then again, additional personal insight is great too!It depends on your riding style and how you maintain your bike... my only recommendation is to stay away from the TP top ends on 2005 & 2006 117"ci motors.
In mostly 05 and 06 big Dog built some of the motors and instead of using a S&S top end/rocker boxes, The used TP (Total Performance) boxes, seems that there was some mis-alignment on some of the bikes causing valve guide wear and or damage. Also that being said there are bikes out there with over 50,000 on this set up. 05 was the first year with this and the heads had smaller valves, intake restricktors (sp) and the smaller E carb. This was done due to looming EPA requirments it also had a Comp Cams cam shaft as well. 06 had the same top end set up but I believe they then switched to the larger G carb. So you had a S&S motor with a few other manufactuers parts.Ok, now you all have me asking why stay away from the TP top ends? I guess I could do a search? Hmmmmm.........
