After being pleasantly surprised at the dyno I decided to pull the trigger on a lightweight crank pulley. In my online searches I stumbled upon one from the Malaysian brand Works Engineering multiple times. Having lost a couple of auctions on Japanese branded pulleys I decided to give the Works pulley a try.
I havent installed it yet but will do so together with the lightweight Monster Sport waterpump pulley. Lets see if this improves the power delivery and hopefully frees up a couple more horses.
Below the unboxing video of the crank pulley, as you can see it looks very decently made. To be continued!
