Are you calling the 8rib pulley the SC pulley and going for 2.85”?I imagine the limiting factor when you get too small of a pulley there you can no longer achieve proper tension with the tensioner. And since people usually go to a smaller SC pulley with smaller idler instead, does that mean this stock pulley is already nearly at tension limit being as small as can without issue?
GMR was our 7am stomping ground, we were the longboarders there early morning before it got too busy/cops. Ventured over to baldy for a bit just to even attempt it and that’s about all i could do such a steep road into hairpins

Input shaft? Are you talking about the jackshaft on the sc side? If so, stock size is a 3.20. I got the 3.25 from 928 . The problem with changing the jackshaft pulley is that the stock one isn't a vortech style and has a different offset so if you put a vortech style (vortech or 928) then you need to add a spacer to the sc shaft in order to bring that pulley out far enough for the jackshaft and sc pulleys to line up. 928 makes a slotted spacer just for that purpose. The actual pulley on the sc I changed to a 2.85. I also had to change the idler pulley to a 3.00 in order to take up the belt slack.
That must have been a rush longboarding those roads. I couldn't even imagine doing Baldy Rd. though. It was a b!tch climbing it on my bike, there are some steep sections.
