My transmission started feeling a bit strange, vibration and loss of power in the low rev range when taking off, so I decided to jump in and see what was up. It turns out my belt was in bad shape. A solid 10cm of the lower/inner corrugation was completely gone. I was somewhat surprised as the belt only had 8,000km on it. It was an Kymco OEM Mitsubishi belt too. Luckily I had a spare, previously used belt, and I've put that on while I wait for a new belt I ordered online to arrive.
While cleaning out the variator I noticed the back plate seems to get stuck easily when pushed right in. I think the 4 plastic glides on that back plate must be worn, so I've gone and ordered a new set of them as well. I'm assuming they are a wear and tare part? The bike does have 41,000 km on it at the moment so it can't hurt to change them.
Did a quick oil and filter chance at the same time. Overall the bike is still running really well. I honestly enjoy my commute to and from work each day on it.
