Glen,
The consensus on the US sites is that the stroker taxes the bottom end too much. The mean piston speed is increased with a stroker.
Dont know how suzuki have dealt with that on the new motor.
1397 is by far the most widely accepted and cost effective, if setup correctly is very relaible. Terry McClure over here recorded a very reliable 215hp at the back wheel on Wayne Patterson's dyno using 1397/cams and mild head work. This motor ran several seasons with little or no problems pulling consistent 9.2-4's on stock wheelbase. Mind you he can surely ride and does consistant 1.4 to 1.5 60'-0.
