something to consider
the quick throttle mod causes the throttle cable to make a sharp bend right at the barrel.
I have been broken down beside the road, twice because of a quick throttle
I think I have had 4 broken throttle cables in over 30 years of riding (street and dirt), and two of those were within 2 1/2 years of each other. Both with different throttle assemblies, but both with a quick throttle mod.
I would hazard a guess that 65% of the broken cables I see in the shop have this mod
If you decide to do this, add throttle assembly inspection to your regular maintenance regiment
