LOL.are you sure you want to go there ?
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.
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.Jug seems fine, I was wot when it happened. But prior to it, it was working fine. No signs of it having issues. And about 1900$ is definitely tempting.
I'll take the 1st. question. You have to have them hard welded. Lot's of places do this, they require a core charge or old usable rockers & cost anywhere from $200 and up for all 3. This is a good idea, but only required for use with aggressive cams or any web cam.How would I go about hardening the rocker arms anyway?
