oem rubber , from dennis kirk $12 a tire!!!
got a new piston, im in the process of modding it like someone who "knows" these told me to do to it.not telling what im doing, then everyone will have a faster little bugga too..
the zinger had a new piston in it when i bought it, BUT... the shop that assembelled it, put the piston in backwards and the rings caught the exhaust port and broke.theres an arrow on the top of the piston for a reason!!dumb butts!!
pistons are.25 over zinger, 70mm, tri-z , and 1.50mm over zilla!!![]()
new tires on the trike.
i have $150 in it now, and thats with the cost of the zinger!
