Hi guys. I've been wanting to put together a 4 stroke since around Thanksgiving. I've already bought a bike (Micargi Stealth), a really nice Whizzer tank, wide cranks, a three piece crank conversion kit, motor mount, Throttle setup, and a manic mechanic hub adapter with a 40T sprocket. I also have a nice set of ape hanger handlebars with a 13" rise D bend. Now it's time to get to business: I'm debating on either getting the Dax Super Titan and the 3.25:1 gearbox, or going with the hometown favorite, the EZM box with the Standard Hua SHeng engine. I'm getting really impatient and tired of looking at a bunch of parts in boxes. Any input would be greatly appreciated as my trigger finger is itching. That 40T sprocket will probably have to be replaced with something larger, either way. Thanks for your input.
