Aaron/Dan,

Can the new Buell Uly oil pump be used in the XR-1000 engine? Or, do I have to go with one of the Zippers pumps.

I have replaced the flywheels/rods with S&S pieces and added windage trays. The cases have also been modified in the case bearing area as well.

I don't plan on doing a LSR with it but, having a nice reliable 100HP motor is the goal.

I know you were getting 150 +/- HP out of your XR motor, but is 100 HP possible with reworked round port heads, 11-1 pistons and the Andrews XR-1 (560 lift) cam?

Thanks again for all your help on this.:clap
