welcome to BF Phil !
whats your plans for rebuilding the topend ?
Yea. It's a few things I wish I done ahead of time, but cylinder is still at machine shop and I can check for a few things before I put it all back together.
As far as top end rebuild Im just gonna get "jug?" bore out abit because it has a few deep scratches and a new namura piston and rings to match new jug. I would like to look to look into porting but dont know where to start. My local yamaha dealer sends off for porting.. and is it a different route for more power instead of porting?
KenOconnor racing on here does a excellent job of porting
Looks like your doing a good job for not being much of a mechanic. You can do anything You want, if you want it enough. A good port job will really wake it up. Are you familiar with carbs and jetting? Thats crucial to good sound bike.
All that stuff can be found on here, just search for it.

Carbs and jetting... I kno what they do but not very sure on which 1 to take out and replace and what size to go by.
