I did my first motorcycle carb rebuild today for my '06 Ninja 500R. Really wasn't that big of a deal. Having the rebuild kit really helped along with watching a couple YT vids and having the Haynes manual.
The Ninja wouldn't start so I felt it could've been the carbs and looks like I was right.
Also put in a new Motobatt battery and a new air filter.
I'm going to have a go at my '90 VFR750F when that kit arrives.
