I haven't fitted the belt yet. Waiting to hear back from Malossi why it's so much thinner than the specs. I'll let you know what they say, and then if I do fit it, how the bike performs.
In the meantime, I did go ahead and fit some Dr Pully sliders (15grams) that I ordered along with the belt. I have to say I'm massively impressed with the result. I haven't been able to get out on the open road yet, due to the entire country being in virus lockdown, but I can ride around the local roads and the bike is so much smoother now, especially in the low revs. I used to get a nasty vibration / shudder from the transmission in the low revs when taking off, or even driving slowly. It would happen around 3,500 -4,500 rpm, and it made riding the bike in that range quite unpleasant. Now it's buttery smooth from the moment the clutch starts to engage all the way up the rev range. I'm shocked at how good the bike feels now. It's like night and day. I just want to keep riding and riding. To be fair, I can't say 100% it's the sliders that fixed the issues. It may have been the variator was sticky, due to build up of belt dust ect as I give it a really good clean before putting it all back together. During disassembly, once I had the variator off, I couldn't simply lift the sliding back plate out of the variator. It was stuck in there tight. I had to flip it over and tap with a steel rod and hammer down through the center hole to fee up the back plate. After a good clean and putting the sliders in it was moving feely.
