You need a yard stick,zip ties,clear plasic tube,I use 2 stroke oil, and some guys have put a small valve at the bottom of the loop. I use one too.
How to page I use 2 stroke oil because if you are way out and suck some in the cyl. the 2 stroke oil will just burn off with no harm. The small valve at the bottom allows you to hook up the tool,start the bike and then slowly open the valve to eliminate sucking anything in the engine because you have control over the liquid.
