After about 6,000 miles, my PCX started making a light whooshing noise inside the CVT (Continuously Variable Transmission). By 10,000 miles it had become very loud, though it still did not seem to be affecting anything performance-wise. Just the same, prudence won out and I ordered a clutch bearing inner face assembly with the bearings pressed in (about $30, so not bad).
I had changed the belt around 9500 miles, and observed the drive plates were looking a bit worn, so I ordered a replacement for those too. These came in the form of NCY parts as it was only a mite more for performance parts than for the OEM equivalents. It seemed there was little wisdom in getting stock parts in this scenario, so I went for the NCY bits with 13 gram rollers.
Everything finally arrived this week, so I braved the heat and did the deed. It didn't take all that long, though I did have to run the clutch assembly to Lancaster Honda since I didn't have the tools to get it apart. Just the socket alone would have cost me more than the $9.00 I paid them to put it together.
With everything assembled, I went for a ride on rt. 283, and got it up to an indicated 74, which I guessed was probably 73. I'll admit, I chickened out at that point and let off the throttle. Riding a tiny little scooter that fast is just a bit nerve wracking.
I did go back after dark when the road was mostly deserted with a GPS running. It recorded a top speed of 71, which is still impressive from a 150. I'm sure if I had a perfectly flat stretch, or a bit of downhill, it could do better, but it's not something I really care to test. That was a bit fast for the little bitty PCX, and I'm fine with what I've learned so far thank you kindly.
So, my first impression of the NCY variator bits with 13 gram pulleys is complete happiness. The low end acceleration felt a bit weak at first, but once I'd ridden it around a bit, it seemed to loosen up.
The replacement clutch inner assembly was well worth it. I no longer hear the constant whoosh-whoosh-whoosh of the worn bearing, and my mind is eased.
