If you mean the position of the lever, yes. Adjustment is by loosening the locknuts and rotating the shaft.Is there an adjustment to control the swing arc of the lever to shift? Don't have manual on me at the moment. Trying to download an online version :-/
lus1: Preloading isn't good idea IMO. It'll start wearing forks and drum because you're making contact while load is still on them. Stick an airshifter with autoshift on there. I have mine set on 65ms right now but it's still stock Blackbird tranny. When I go in to do piston kit, I'm sending it to R&D tranny's and letting them do nitrous/turbo cut on it. Then kill time is dropping into the 50s.But are very likely to bend the shift forks eventually.
There's no need to load it.
