150cc GY6 scooter lost top speed

Slightly off subject. I had a Suzuki Burgman 200. It started to slowly suffer a speed loss and would get a bit wonky on the top end. I pulled it apart and found noticeable wear on the variator faces at around 3000 miles, both fixed and the side that contains the rollers. Suzuki wanted mad dollars for a new assembly so I found a used assembly on ebay. Gently used ebay variator suffered the same fate at around 3000 miles as the original one. Turns out the variator faces were not hardened correctly. We have a metals lab at my job and I compared the drive face hardness (or rockwell rating) to a found technical spec from Yamaha. I luckily found a Malossi variator that worked great, I just had to replace the fixed face at every 3000 miles. Thankfully Suzuki lowed the price of that wear item part. Maybe they knew of the problem? That scooter made me hate Suzuki and I'll never buy one of their products again. Impress me with the base/entry level model before I buy a high end model.

I honestly suspect something transmission related as mentioned above. So if everything looks good then you may wan't to consider a performance variator.
