Scott, my rear brace was welded in when the chassis was built so unbolting not an option for me. Good suggestion on the throttle springs, I'll look into that. If I understand you right, you replaced 4 throttle springs with a single spring, which for me would be on the common central linkage pulley on the block.
I believe a big problem for me could be the throttle cable as it is the standard supply that has a stainless steel inner cable with a steel wound outer spiral (a standard Bowden cable). I am going to replace this with new cable that I bought today. It has a Teflon composite inner liner between the inner cable and the outlet sheath and apparently offers very little friction on the inner cable even with tight bends in it. I will probably also look at relocating the foot pedal cable location as Keith has done, but I may need to modify the throttle end as they will be less travel at the foot pedal end. There are two connecting points on the pedal already so that should be an easy change.
