No I didn't remove the chain guide, just 1 bolt and used it to bolt the bash guard on over that part of the chain guide. It's clears the chain and sprocket, I was worried it might rub. Use loctite. Will field test this weekend with a ride, but think it will be fine. My old shock pump seal gave out after pumping up my son's Moro, we have 3, so I upgraded to the Rockshox 600lb pump for ~$30? It's a high capacity pump that raises pressure faster per pump. My old Pump I was pumping a long time to get up to pressure, once. Next bike, it lost pressure each stroke. Rear travel is 150mm and don't forget to select ebike and Lbs instead of KG, and don't exceed max pressure.
