This is a set of the conventional high-performance Marossi 68cc bore-up cylinder kit with "manual deburring".

Due to the rise in import prices, we have revised the sales price. This is a set of the conventional high-performance Marossi 68cc bore-up cylinder kit with "manual deburring". Since the piston ring is already attached to the piston and fits in the cylinder, there is no chance that it will be broken or missing when the product arrives. If you remove the ring yourself or attach it to the cylinder without aligning the abutments, it will break. Do not remove the piston ring or force it into the cylinder without aligning the abutments. There are no guarantees or returns for damaged piston rings. If you break a piston ring, please purchase a [repair/spare piston ring] sold separately. The kit contents are as follows. 1, Cylinder 2, Piston 3, 2 piston rings (already attached to the piston) 4, 10mm piston pin 5, 2 piston pin clips 6, Exhaust gasket 7, Head gasket 8, Base gasket 9, Carbon reed valve 10, Stud 2 bolts 11, Main jet #85 (small round) Setting tips (The included main jet corresponds to one or two holes drilled in a normal air cleaner.) First, install the largest main jet. If you can't drive in that state, change to a larger main jet. Once you find a number where you can't run anymore, lower the number by 5. (Always check the condition of the plug. Problems with the plug may cause it to continue to fog.) If you find a number that allows you to run normally, do not lower the number. Set the detailed rotation speed using WR. Please be careful not to lower the main jet number and increase the rotation speed. *The quantity and design of stickers will vary depending on the lot. *Please note that if the stud bolts are installed in the opposite direction, the flange will crack. Note (Disclaimer) > Please read *If the stud bolts are installed in the opposite direction, the flange will break.
