The Airsal Xtrem kit is designed to comply with cubic restrictions for various racing cups abroad, by making the kit fit the standard stroke of 40mm. This means that you have a wide selection of cranks to choose from at the same time as you get a kit with lots of power and profit. However, the 50mm bore means that you have to mill the crankcase up to make room for the putty and the piston. ATTENTION If you want to mount the kit on Euro4 models, you must use this adapter for the temperature sensor.
It is recommended that you drive at least with a 21mm carburettor together with the cylinder kit. All necessary gaskets, cylinder head, piston and piston ring, snap rings, exhaust bolts, etc., as shown in the picture, as well as assembly instructions are included.
Note: Because the bore on the cylinder is 50mm, you must mill the crankcase larger to make room for the kit.
