I believe they're all the same . are you having a fitment problems or just notice the bolt looks different. when they're tweaked or aftermarket radiators, there's a sequence to install it that helps. I forget what it is.. start at the bottom left or something like that... maybe somebody will chime in Sent from my SM-A505U using Tapatalk
You can get 100+ hp outa a stock cylinder. How you get there and what its good for are 2 different things. Going off a video doesn't make much sense... but to each their own

Up Compression, better air filter / airbox mods, bump timing to 4゚, pipes, good tires, sprocket change to your liking... after that , you'll need to get port work done Sent from my SM-A505U using Tapatalk
There is no set idol turns, did you sync carbs after? Intake gaskets tend to leak, might want to do a leakdown test too. Sent from my SM-A505U using Tapatalk
