Ouch. Thanks. I was expecting to have to grind or replace the front alloy guide/saver, and possibly have to notch the nylon chain guide to install it, but having to grind some of the clutch slave, and pull the swingarm too is too much to be convenient so I could swap back the 13T for woods work. I'm also using a 50 or 52T rear (can't remember) and it made a huge difference for me from the stock 48 for extreme stuff. Guess the next idea would be to find a parted out rear wheel to put a smaller rear sprocket on with DOT rubber.
Thanks again.
