Restored and Upgraded Throttle Bodies for K1 / K75 / K100 / K1100 / K1200

Each throttle body has been disassembled, degreased, and acetone dipped to prepare for media blasting.

All parts are blasted with aluminum oxide to remove years of oxidation, "resetting" the metal. Then, followed up with glass bead blasting to bring out a "better than new" brilliance.

All bracketry is clear coated in a semi-gloss finish, protecting from the elements that encourage rust.

Hardware has been switched out to A2 (304) stainless steel. The throttle advance "choke" roller has been upgraded to a nylon, low friction replacement to allow for continual, smooth operation.

All seals (butterfly shaft, TPS, idle adjust, and vacuum caps) are replaced and coated with high vacuum, silicone grease to prevent vacuum leaks and degradation (critical for 2V bikes).

Butterfly sync grub screws switched to a black oxide hex for easier adjustments, locked in place with a nylock nut to keep it from working loose over time.

Butterflies polished, then cinched down with screws that receive Loctite, preventing them from backing out. All are benched sync'd to allow for easier tuning (balancing) when bike is operating.

Bracing bars are replaced for NEW stainless steel ones and polished to a mirror finish. 

Along with the standard K75 / K100 throttle bodies available, there is the additional (limited) option to have the larger 4V throttle body bores already converted for 2V bikes, allowing for more air. This includes throttle bodies sourced from K1100's, TPS converted for 2V, throttle pull/stop converted, and rear balance ports filled with epoxy, as it's not used for 2V operation. Recommend upgraded injectors to compliment the additional air allowed by the larger bore size. (Recommended on standard bikes as well). Recommend replacing fuel pressure regulator if original.

TPS, balance, and idle adjusted for initial start, further adjustments may be needed for your application.

Don't forget a fresh Inlet kit for your K75 / K100-8V
