Hello everyone, I recently picked up a moped.
Yesterday I changed my belt and after one ride of 30 miles the belt snapped. This isn't the first time it happened. I've snapped 3 belts in the past month. So it seems as if there is a evident problem somewhere in the CVT lol.
Parts that have been upgraded after I owned the moped are 50-100CC BBK, Stock Head, Stock Exhaust, Performance Clutch 2000 RPM Springs all around, 6.5 Gram Rollers, Geared 49/17t, Carb Upjetted 88, Spark Plug, Oil Change, Transmission Oil Change.
The bike runs good now but I noticed it doesn't really like drive belts. I drive the moped pretty aggressively so to speak lol. I hear after the first install of the drive belt you must also break in the belt. I haven't really been doing that I just romp on it once I install it lol. I noticed on my moped the belt doesn't actually sit real flush onto the variator shaft. When you install the variator there is a long cylinder piece. I make sure to push my variator all the way back to the back wall where it should be sitting. After doing so I notice not much room on the variator cylinder piece where the belt sits. I also push the cylinder piece back into the variator all the way to ensure its sitting correctly. Should I push that variator cylinder piece out a little more so my belt can sit on it? My belt doesn't fall off of the variator cylinder piece by much it just falls of by maybe 2/5 of an inch. Since my belts been shredding so drastically I could only think of small stuff like that.
Also the bushing inside the case is still solid no wiggle room. Talking about pulling the variator cylinder piece out I could only imagine that would cause issues and regardless when you install the variator fan on that will push that cylinder piece back? I notice the belt doesn't quite sit flush onto the cylinder piece and I feel like that could be a potential problem. Is there supposed to be a washer/spacer in between the variator cylinder piece and variator fan? This is where the variator cylinder piece touches the backing plate of the variator fan plate. I'm wondering if I should put a washer/spacer there? Wondering what everyone else bike runs?
My moped is a 50cc longcase GY6 12' wheels. I run a 729 / 17.5 / 30 belt. The belts I have been using are non kevlar. They are rubber chinese aftermarket cheap belts. What do you guys think? I'm going to upgrade to a kevlar one today and see what she does. Any help is appreciated! Thankyou.
