I'm going to have to do that. Is there a trick for doing the oil seals as well or are they fairly simple?
Thanks for the added note  :)) I'm sure she would find a reason to get made at me for it.

Also what is jerry's screen name so I can get in contact with him?

Alright so I got in contact with Jerry and the cases and crank are going for a road trip tomorrow, to get checked over, fingers crossed  (Y)

I cant help but wonder if I should take the power valve out of the cylinder and some how inspect that as well?

Also what kind of fixes is there for my head since its all chewed up?

I would have it oring and squish set on it. Will help it start alot easier. Better performance.  Runs around 100 $ or some more. But worth it.

would that take care out the dome being all chipped up? or should I have that ground out and the head shaved so I do not lose and compression? along with the oring and squish? and is Carl (iceracer) the guy to go to for the squish and oring as well as porting probably?

and when you say easier to start do you mean it wont kick back as much? I've got a gnarly hole in the bottom of my boot from that kicker already.

I mean kicking easy, like starting on primer kick. That kick back is from timming  or few other things.   All those dips should come out when you have have squish set. Dont grind or shave on the head. If worse comes you might have to get a different head. Yes Iceracer is excellent choice to do the work to your topend. My cylinder and head is setup by Iceracer. Its runs really well and im really happy with it.

ah ok, now its all starting to make sense. well, fantastic after I get the lower end back from being worked on I can ship out the top end to get worked over as well, I'm thinking a hone and bore if needed, some mild all around port work, then squish and oring. Then pick up the RM bearing and billet thrust washers for my Wiseco piston kit.

Anything else I should be looking into?
