Ace, We're not putting new rings on my piston, right? (Less than 1,000 miles).
Nope. No new rings.We are confining our piston work to valve reliefs on the crown, only. And only minimal ones that won't be deeper than necessary.I'll be going to Mondello's tomorrow, so I'll see how it's going.
Tooseevee,My 2006 AVL did not come with hardened washers under the head nuts in the rocker boxes too. The nuts outside of the boxes do. I have run it this way for 35,000 miles with no ill affects that I can see. Maybe they are not needed in there. The head nuts on my AVL have flanges on them. Can someone shed some light on if hardened washers are needed or not under the nuts in the rocker boxes on a AVL engine?Royal Enfield people are good peopleCheers,Bill
They are working on the combustion chamber re-shaping right now.
Here's how happy THAT makes me: Do you think you could send me a picture when the seats are in & finished & beFORE you install the valves? I'd like to be able to document things to a new owner (which must happen some day no matter how much I don't want to think about it).
Okay, the custom valves came in, and the chamber and port work is commencing.It is looking like a couple of weeks to completion now. Maybe less.It appears that the head gasket is thick enough to provide enough piston to valve clearance, so I think we won't need to cut recesses into the piston crown.Will update when we have some more info.
Happy Dance Happy Dance Be really sure about the valve clearance (I know you will). It would be horrendous to jam a valve first trip down the road. Here's what I did a few weeks ago. I was bored:
Looks good! How did you do that?
