Powerful Turbo XJ650 Build - Satisfying Custom Motorcycle Build

Video Description

Welcome everyone! In this video, we turn an old XJ650 into a fire breathing cafe racer! After much tinkering with the jetting, we switched back to the HSR42 and it now runs mint. The needle taper on the HSR42 is much to lean for a 4 cylinder; on Patreon, I made a video explaining step-by-step how I altered the needle taper so that this bike transitions smoothly from the needle to the main circuit. There's now over 11 exclusive How-To videos on our Patreon, our most popular video is "How-to Turbocharge your Carbureted Motorcycle From Scratch; Draw-thru, Blow-thru; a Complete Guide". In this video, I break down everything, right down to the nitty gritty details like Fuel Pressure Regulator Selection, Fuel Pump Selection, Pitot tubes, how to hook everything up, basic troubleshooting and more! www.patreon.com/DoctorMotorcycle www.doctor-motorcycle.com instagram - doctormotorcycle_az This is my 6th turbo build and my 5th draw-thru build. The reason I like draw-thru setups is the simplicity of the design; even though you give up some driveability and fuel economy, in my mind it's a worthy trade-off. I had a float stick on one of my blow-through builds and it flooded the top end of the motor and left me stranded; I was so mad about that I tore off the turbo setup and sold the bike, lol.
