 Product Description

buying-2-discount-300pxl-.png● 140CC (53MM /12MM PISTON PIN) LOW COMPRESSION LIGHT BORE KIT (2021 GROM125 - 2021 Z125 MONKEY - 2021 W110i/125i...)

● YUMINASHI was the first tuning brand on the planet to be able in giving a positive reply to the global demand for a plug & play 140cc Light Bore Kit which includes the 53mm K1M piston with 12mm piston pin for the stock 110cc & 125cc crankshaft and cylinder head.

(Stroker parts also available (LINK)).

● This 12103-K26-G53C 140cc Light Bore Kit is the low compression version kit we have released and comes complete with the 53mm cylinder, a dish style low compression 53mm light bore piston & piston rings (LINK), 12mm piston pin, 12mm piston clips, and the 140cc gasket set (LINK), which includes the black cylinder base gasket and the 53mm premium grade single copper head gasket to ensure you the perfect seal on your engine.

● The compression of this kit is comparable with the stock compression ratio if you install a high degree camshaft, and only slightly more than stock if you install the stock camshaft, so this kit is perfect for anyone who wants to have a larger piston installed to suck more air into the engine, but doesn't want to raise the compression ratio...

※ If you want a big bore kit to raise the compression ratio, then we have you covered because we have the high compression 140cc Light Bore Kit also available with this (LINK), which allows you to make a choice concerning the bore size and the compression you would like to see on your engine tune....

※ We strongly recommending to install our SS241 camshaft (LINK) with this cylinder kit, if you install a higher lift camshaft, then it could be that the valve pockets in the piston need to be modified based on the lift of your camshaft (This will be fine with 95% of the camshafts available, but it's always worth to check this to avoid damage).
※ This 140cc Light Bore Kit needs to be installed with minimum a 140cc/min B-type injector (LINK) (flow rate of the injector to be used will be based on your location in the world)...
※ The 5-speed 2020 GROM125 and 5-speed 2021 Z125 Monkey models are called "the 2022 model" in the USA...
※ 140cc is only achieved on the 125 models in combination with the stock 125 crankshaft and not with the C110 or Wave110i 110cc crankshaft.
※ We recommend to install a 14T front sprocket (LINK), because the 5th gear ratio is way way way too heavy, and you will never be able to make a good top speed if you shift to 5th gear with the stock 15T front sprocket installed (if you are a person with a +100Kg (220 Ponds (lb) then we recommend to install a 13T sprocket (LINK))
