After waiting a long time for SYM to get their act together with parts, I gave up. Now Billie, my Symba, has an O-ring chain and brand new SunStar sprockets . The O-ring chain is no doubt overkill since I have a covered chain and now know how to take care of it. I don't care. Overkill sounds just fine by me.
I've been very pleased with the difference the new sprockets and chain make. It is almost like having a different bike. It is much more responsive off the line and cruises at 45mph+ easily. I am very happy. Because the chain was pretty well cooked, I've been staying close to home this summer. I haven't even been riding Billie over to see granddaughter. Now, I not only suspect this will change, but that there may be some longer adventures on tap. We shall see.
Since riding a 101cc motorbike puts me somewhere between a touring bicycle and a motorcycle I decided to add a flag to increase my "being seen" factor. It's not a traditional orange triangle, but the dots are reflective and the green is hi-vis. I figure what can it hurt? And, besides I think it looks almost cool.
