22mm intake, 20mm exhaustSiKfIdDy said:i will be putting the tb cam in a e22 head with tak heavy duty vavle springs after some sik head work(machining bigger intake and xhust ports and custom vavle and port job) with a xr70 tb 88cc kit for the domed pistom with a 22mm carb and intake. i think it will run pretty decent. any one know the sizes of the tb intake and xhust ports.
