Ok well not to be opposite from everyone. Because yes a port job would be great for you. But i recently traded some parts from my yz to a guy and he gave me a brand new Athena 392cc kit. I really like it, not only does it have get up and go on trails but it runs badass when its wide open. But i ran them bc the parts i traded i didnt need, if i were looking for more power, i would have went with a port job. But overall these get a thumbs up!
