Since it's cold and I can't ride I'd like to do Dr. Pulley sliders but I don't know what weight to choose. Stock rollers are 21.5g, correct?
1) What weight should I pick to keep RPM near stock for highway cruising speeds but gain some acceleration from a stop? I plan on doing a lot of highway riding this coming summer and don't want my RPM to go up from too light of sliders. 19g seems like the lightest I'd want to go. What about 20g or even 21g, would that keep my RPM down at cruising speeds yet help down low?
2) Do I need 4 new variator slides since my MP3 has low miles and the stock slides should be in good shape?
3 Can I get the variator off and on without a special variator tool? I've got an impact and a strap wrench, will that work?
