I have been addressing this issue in the Like 50 area, but want to know if anyone else might have a thought on this.
I ride a Like 50 2t and recently installed a Jasil/Top Racing variator. An issue I had had was yesterday after installation (and an initial startup that went well) incurring a grinding sound with no start. This morning I went into the case and discovered that the ramp plate was 'stuck' on the shaft. It's inner diameter was slightly thinner than the OEM (about the thickness of paint, which I scraped off). After making sure of good fitment, I reinstalled the vari and my fasteners are all attached well, but on start-up, there was a grinding sound still (though the engine does turn over and it appears that the cvt is turning). From what I can tell, the bendix is not disengaging once the engine starts. I am assuming this because that is the location of the sound, the kickstart shaft has some movement after startup, and there are some fine metal flakes under the bendix. The washer has been in place each time I return the cover. I did start the engine yesterday with the cover off (and without making sure the bendix was retained), but at that time, the engined turned over well and CVT pulleys turned freely.
Any thoughts or experiences are greatly appreciated.
