88cc cylinder for you, although this is not a bolt-on item for most QMB 139 bikes. Most of the time, engine cases need to be cut. Order part number 1400-1001, Engine Boring Tool if there is no access to a machine shop. It is also recommended to get part number 1100-1239, along with the 50mm valve head, as some stock heads will not fit. Take a look at our decompression tube assembly which replaces your gauge and allows excess pressure to be released from the crankcase. Good idea to install one of these alongside a cylinder kit upgrade.
