Yuminash S238 camshaft

Something strange going on. I've read plenty about CT125 being fitted with this camshaft with good results and Yuminashi sell it as being suitable but the damn thing is too long in my 2021.

The bearing isnt pressed on all the way

Big socket and a vice?

happened to me on my s238 as well. just find a socket that fits over the inner bearing race and tap it down with a hamma

Thanks that's what I did the cam makes quite a big difference it feels like a bigger bike for sure and somehow it's quietened down the exhaust popping and general noise which is a bonus. I've fitted it with the Yuminashi adjustable cam sprocket.

What else do you have done, Selly?

I've done the Yuminashi 143cc, efie, Takegawa exhaust, PCX 150 injector, opened out the air filter and the s238 cam. It runs great, just came back from a 700 mile ride around Wales in the UK with the standard cam and it ran great, now with the cam fitted the torque is really on.
