Cheap cush drive option

2002 XR650L

So I was doing some research on gearing and found a couple of interesting (to me) tidbits.

1. Avoid installing smaller sprockets where practical. The more a chain has to bend, the more wear it puts on it. So if you gear down, increase the size of the rear sprocket. To gear up, increase the size of the front sprocket. Y'all XR650l riders running a 13t front may want to take note.

2. A larger rear sprocket acts like a cush drive in that it somehow softens the pulse from the engine. That's what I read, so I tried it last night - put a 48t on the back (stock is 45t). I did notice a big difference, although I also noticed a difference (but not as great) from gearing down on the front sprocket also. I can tell you that compared to stock my bike has WAY less of a juddery ride - how much of that is down to the gearing v. larger rear sprocket - I'm not sure.

That's all!

If you use synthetic oil your bike will gain 5 HP and the motor will last twice as long too!
