One has a number of options to carry out this mod. One is the BDX option, the small bottle with oil only going to the pump drive void option, the hose to the bottom line option, the grease to the bottom line option, the oil delete cap grease fitting option (D&D) and the case drilling with a line attached between the PTO side and the bottom line fitting option. I actually did the BDX with the case drilling and greased the BDX before I installed. My option choice was based on a number of reasons...first twisted turbo uses the case drilled option for their install with very good results, in fact our local dealer has been installing twisted turbo for years with no failures...the BDX delete has a good bushing in it....the grease well just a good added bonus. Wet weight loss is about 11 lbs, better mixture control, get rid of the crappy pumps, lighter throttle, a good place to put a torque stop which only cost about $8.00 to build.....Cheapest 2 mods one can do to their sled......
