LOL.

I would leave the porting to the Pros. Use RHC, Alba or any other reputable machine shop.

I bought Kibblewhite valves and springs off of Amazon. I went +1 on the intake. I am sending the head the valves to Alba for their porting and valve job. Just waiting for the tax return.

what are you guys paying for this work, and are you really seeing that much of a pay off?

Just saying if you have the time to do it yourself one could save several hundred dollars.

it does help tp clean-up the intake port " For every 1 CFM of increase in intake flow, you'll gain .43 horsepower. "
but,... hard to know how much you have really done/helped with out a flow bench.... mixxer was a great one for dong a big bit more than should of been done .

I guess you were mistaken on the jug being fine! I scrolled back through this thread today on cell phone, and all four of those pictures appeared fine. Idk where your ordering parts from, but partzilla.com is cheap, just don't be in a hurry. And best to call and dbl check they have the parts in stock. Also wondering what part of the world your located. There are lots of builder's on the west coast. And you can always ship motor to them. Or if your east side there's Ehs racing. On the honda atv forum there's a sponsor called.

Man, seems like thereís a lot to think about when it comes to the head.
How would I go about hardening the rocker arms anyway?
I live in the east side at Miami, Florida. I have a friend that knows a guy that can help us with porting it since heís thinking of porting his head as well.
What if I just port it and not do the Valve job, would it make any sense to go with the +1 mm? And if I donít do +1 mm should I go with kibblewhite or OEM?
Iím thinking theyíll replace my valve guides too right? All 4 of mine are cracked. Managed to get 1 out by drilling it through but havenít tried putting it in the oven yet, donít wanna drill the other ones through if the oven truck works and itís a pain to drill them out. I know itís a lot of questions guys, I really appreciate all the knowledge.
