If the slave was leaking you would see fluid in or around the bell housing. I'm guessing there is still air in the mc. I always bled mine by hand out of the car. It's a pain in the ass but youd be surprised how many little air bubbles still come out even when the peddle gets firm. Have you tried bleeding it on the transmission? If you drive the car hard a new clutch setup may be in order to.
I don't know what your budget is but check out either of the go-ped super go quads. I had the 42cc street one and it did about 30 with me in it. Their off-road one is legit. I think they're about $1500. Parts are cheap too.
I'm sure the tick piece is nice. I never had issues with mine and beat the shit out of it with no issues. Before I drilled it my clutch would stick to the floor. Pretty sure gm designed the mc that way so people would break their shit.
Do they all do them or is there a specific one? Their website doesn't show anything other than the form and that I need to have it done. Colorados dmv was a one stop shop, seems like the Ohio dmv system is much more over complicated.
