Even with the heavier engine, I don't think it'd even be close. The magazines put he new KLR at 37HP 32 Ft llbs of torque.

From the web..
Model Yamaha XS 650 F 1979
Power 54.8 hp (408.6 kW) @ 7000 rpm, Torque 58 Nm (42.8 ft. lbs) @ 5500 rpm
And that's box stock which it wouldn't be when I got through with it.. Damm it would be a fun bike to build...
