‡ S&S does not recommend compression ratios higher than 10:1 for Tri Glide® or other three wheel models (including conversions) due to extra loads caused by the lugging nature of these bikes Detonation and subsequent engine damage may result Twin-Cooled applications will require separate purchase of 900-0609 head gaskets The 117" cylinder kit will reduce the engine height ~ 060", this may require the stock manifold be shortened by sanding some material off each side of the intake runner Cylinder w/piston kits included in this Hot Set Up Kit are pre-fit and ready to install 2008-up touring models with electronic throttle control recommends S&S Throttle Hog 58mm or 66mm Throttle body and Harley-Davidson® race tuner This kit will require that the case be bored to accept the larger cylinders 030" MLS head gaskets optional: Part #900-0217 S&S recommends retrofitting a Timken bearing (31-4013) into 2003–'16 model crankcases with the use of a Timken sleeve, Screamin' Eagle #34822-08 or Jim's #956 A charging system spacer for 1999–'02 model year is also required S&S p/n 310-0761 Requires recalibration
