I measured the width of the E model 17" wheel & the L model 16" wheel. Measuring points were from the inner surface of the brake rotor to the CL of the sprocket. I find that the 16" wheel is more than .5cm wider. Now that may not seem like a lot. But it is rather significant.
Sprocket alignment is pretty critical. And a .5cm can result in premature wear and shortened chain life. I would never have given it much thought if not for this situation. Bill, I wonder if your sprockets are truely in alignment?
In order to ensure proper alignment Suzuki engineers designed this reversable front sprocket with different faces on each side. For the installation on the L model the sprocket rests flush with the inner spacer plus a flat washer. On the E model the oposite side of the sprocket slides OVER the spacer. This places the sprocket slightly closer to the engine case. How much would you want to bet this difference is .5cm? I haven't measured yet, but I'm pretty sure of what it will be.
Still I'm surprised at the poor design to prevent the L model sprocket nut from loosening. I'll feel better when I can install that bendable washer over the nut. A much better solution.
