Z needs a rebuild...
Alright, she finally went. Just died when I was loading her up, glad it happen then and not in the trails. Wouldn't start back up, plug was ok, checked compression... what compression? So basically what I'm asking is what's the best way to go for a budget, but wanting to make this rebuild worthwhile. The three options I was looking at were the Athena kit (like $450ish), Wiseco big bore ($250 plus $200 cylinder work), or JE HC +2mm ($140 plus about $150 labor). The only benefit I see with the Athena kit is saving on labor, and that comes to about the same as the Wiseco after labor. I'd save some on the JE but would it be worth doing? Whichever I do I'm putting in an intake HC. Any other suggestions? Also getting a DID cam chain and new tensioners. I want to do this once! Thanks for any help guys.

What specs should I know for porting the head if I get Int and Exh Hotcams? Or should the shop know what to do by the info with the cams? I was originally only planning on an Int cam and no porting but if it's worth it... might as well I suppose. How about the Kibblewhite valves with DRZE springs? Anyone have any opinions on the JE 453 kit? It comes with a sleeve. If I'm going to spend this much money (didn't really plan on it...) might as well make sure I get everything. What about jetting and ignition? Will the Mikuni carb be fine? And what about the cams, will they fit fine or is the shim kit really needed? Think that's all the Q's I have...

a good shop will know how much to port the head, drz springs would work great, if you do the intake cam only, its for low end power.
any kit that comes with a sleeve you still have to pay a machine shop to install it, your carb should work fine but you will have to rejet it and yes you will have to reshim the cams for the valve lash no matter what valves or cams you use

Athena kit (like $450ish)
From what I read porting is only good for a couple hp if done right. If not done right it can easily cost a couple hp.

Yeah I was definitely wrong on the Athena kit price. $600 is average. Well, I'd prob just have the shop install cams and valves/springs if I get the head ported and have them get the shims needed. But then maybe I should just get a +2mm JE high compression piston and bore my cylinder to save some money. I know I'll get more out of the Athena kit, but I didn't have a problem with power before, and adding an intake cam (still uncertain about porting the head and exh cam), with stronger valves and springs should already be better. I don't know, I just don't have $1200 to go all out and hate not to ride for like 2 months... undecided.
