Apollo 250RX db-36 front and/or rear sprocket changes for torque & part selection

[Kawboy]

I have installed a 52 tooth sprocket on the rear, I’ve cut back the lower chain guide to where the sprocket doesn’t run against it. My question in relation to this is that when rotating the wheel I feel the degree the chain runs off of it and into the teeth of the rear sprocket is causing excessive vibration(significant bounce when chain leaves the lower guide). Will this be fine or should I remove the guide all together.
