● 145CC (54MM /12MM PISTON PIN) LOW COMPRESSION LIGHT BORE KIT (2021 GROM125 - 2021 Z125 MONKEY - 2021 W110i/125i...)
● This 12103-K26-G54C 145cc Light Bore Kit is a low compression kit we have released and comes complete with the 54mm cylinder, a dish style low compression 54mm light bore piston & piston rings, 12mm piston pin, 12mm piston clips, and the 145cc gasket set (LINK), which includes the black cylinder base gasket and the 54mm premium grade single copper head gasket to ensure you the perfect seal on your engine.
● The compression of this kit is will be higher compared to stock compression ratio because of the 54mm piston size, even if you install a high degree camshaft, but you can be ensured that you won't be overdoing things, which could lead to blowing the piston up, broken rings lands on the piston etc, so this kit is perfect for anyone who wants to have a reliable kit, with a larger piston installed to suck more air into the engine, but isn't looking to raise the compression ratio by a lot...
※ 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 145cc 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, if you live close to the beach (sea level) then the 8-holes 170cc/min injector might be a better choice for you LINK)...
※ The 5-speed 2020 GROM125 and 5-speed 2021 Z125 Monkey models are called "the 2022 model" in the USA...
※ 145cc displacement 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))
