barry.. that is exactly what i was looking for.. so the sa 125 is pretty equal to the ys 1.10. I wouldl likely need to throw on a cline reg or perry pump neither of which I have ever needed to used with the ys 1.10. I always had trouble tuning the ys and was thinking maybe the sa 125 would be easier to tune with either the cline or perry. Anybody have any experience in the comparison as far as tuning in this situation?
