Very easy install

I would give a 4 star due to the fact it didn’t come with installation instructions but if you are doing it yourself anyways you should know a little mechanics. Super easy install I didn’t have any questions or concerns to even need instructions. Was even able to do install with motor still in frame. New carb and the bike came to life.
