Took my opposed. I have a valve compressor thank god. Had a diagrinder and a multicarb bit. Grounded the ports of intake and exhaust. Made it smooth and polished it. Polished the head. Carb is polished intake it grounded out and polished. Runs like a beast. With regular gas and methanol mix. Doing this to your motor does improve torque alot

Me and my buddy did this to a 14.5 hp OHV briggs motor I had sitting around and it starts easier and runs smoothly still haven't ridden it yet because we need a rear end, it also is a lot quieter
