    785 Flat Top Jetting and Carb Settings

    Compression 170/170. Haven't pressure tested it. I have tried two different coils that I know work. Tried two stators Tried two flywheels Tried 2 cdi boxes Tried 3 different sets of carbs Tried 3 different ways of routing cooling Sent from my XT1650 using Tapatalk

    Has anyone ran a cooling line from the pump to the bottom of the headpipe? I just saw a diagram of it being routed that way. Sent from my XT1650 using Tapatalk

    Another dang FX1 pump thread......

    I have a thought about the drive shaft set up. Why not leave the yamaha housing in place along with the midshaft, remove the drive shaft from the fx1 pump. Cut it back and have it splined to match the 650 impeller. So you would have a drive shaft that is yamaha splined on one end to fit the...
