Haha, did the same thing a few years back.. def not hard, just time consuming. Mine was way more filthy than yours appears to be. While you have it out might as well get into your plugs and even your cam chain tensioner if you think it needs swapped. Once its back on the frame it is a pain.

 

Hey bro post some pics of your bike..... looks like you pulled all the wiring with it. Ill probably end up doing the cct. No issues with mine yet but probably will do it for longevity. Plugs are like a year old so ill just do an inspection on those.

 

Good luck with your build man. Patience is the key. I spent 8 months on mine.
