Ultima 113" Twin Cam Replacement in Blackout Finish
Pevely, Missouri based Ultima Products has added another option to its 113" Ultima Competition Series hydraulic chain tensioner replacement Twin Cam engines with availability in the popular Blackout finish, rounding out a complete range of four finish options, with polished, silver and black also available.
A direct bolt-in engine for '99-'06 "A" motor Twin Cam bikes, "just like our EVO style engines, this engine features high quality components at an affordable price.
"These cases utilize Timken sprocket shaft bearings, and the crankshaft assembly is the same one that Ultima has been building for years - dynamically balanced and featuring forged H-beam rods for a rock solid foundation.
"We use late model cam bearings and pinion bearing, counterbored stainless Allen head case bolts and manufacture to close and precise machining tolerances in prime C356-T6 aluminum that is superior in strength to A356.
"The pistons are forged aluminum from Mahle Motorsports and the heads feature conical valve springs, chromoly retainers, manganese bronze guides, compression releases and stainless steel valves. Valvetrain components include an Andrews 67H set of cams and Ultima’s 4140 steel adjustable pushrods - topped off with 4140 forged steel roller rockers.
"The cam chest components include a billet oil pump and billet cam support plate with late model hydraulic chain tensioners - with plenty of power, these engines make a great replacement for a tired stock motor or a custom build.
"Our state-of-the-art designed crankshaft incorporates a massive 1.670 diameter pin that is pressed into the one-piece heat treated 4140 steel flywheel halves, making these crankshafts some of the strongest available on the market today. Crank pins are installed with .008" press fit. These crankshafts feature lightweight 7.67" long H-beam rods with 0.927 diameter wrist pins and are balanced using our exclusive methods, making these some of the smoothest engines in the industry.
"The cylinder (and head) is a C356-T6 casting with cast-in liners that will just not move. All the fins are machined for an excellent cosmetic appearance. The head has 2.100" stainless intake valves and 1.700" stainless exhaust valves."
