i'd like to fit a vernier pulley to my kent gs2, so i can make sure it's set optimally. can anyone recommend a good make of dial gauge to do this? don't want to go mad but i'm happy to spend up on something accurate that'll last. prices around 50-75 ish? neds to have a magnetic or clamp stand too. was going to get a kent pulley to match the camshaft, unless there are any better ones out there? kent's hard to beat pricewise at about 110 delivered. thanks all edit: what sort of range would i be looking for to do this job? think i'm going to be using the lift on overlap approach.
