Took my bud's engine apart and found that the intake valves are pretty loose. Im thinking they might need to be replaced, would it be ok to replace them with OEM valves? Also, my dealer has them for $19ea., anyone know where I can get them cheaper? We are also thinking about polishing the exhaust runners since we dont want to mess with the intakes or air/fuel mixtures. Any advice?

 

I got a set of intake valves for 17 each from my local dealer, and it wont hurt to polish all your runners
