Yuminashi SS241 Camshaft for Honda MSX - GROM125 JC92 - Monkey125 JB03 - ST Dax125 JB04 - Super Cub125 (JA14E)
● The YUMINASHI 241 degree SS241 camshaft has been designed for use in stock and large bore/large valve engines to bring your 110cc or 125cc Euro-5 engine to life. Once installed, you'll get the extra oxygen your engine needs to make powerful pulls from mid to top revs.
● The lobe angles and duration have been carefully designed to be a Super Sport camshaft, not a track racing camshaft which would typically have 250 degrees or more, so you have the perfect compromise between making power / good pulls from mid to high revs without suffering from good torque at lower revs, and without any problems either starting the engine, or running perfectly at idle.
● The SS241 camshaft can also be fitted perfectly in the standard 110 and 125cc cylinder heads without the risk of the valve spring coil jamming and without the risk of hitting the valve guide/valve seal with the retainer.
● If you have fitted a 140/145cc big bore kit, we have also covered you with the SS241 camshaft, as the 2 small holes you can see in the camshaft are used to remove the decompression system from your stock camshaft to reinstall it on these 2 small holes in the YUMINASHI SS241 Super Sports camshaft, easily solving starting problems on high compression engines.
