Not too much rain here in Anchorage. Plenty of snow, though it got nice and warm today. I think a high of 37*f
Tinkered around with a few items today since I can't finish the head. Put new bearings in the wheels. Took off my old rear sprocket and replaced it with a new one. The new swingarm requires a longer chain, so both sprockets are getting swapped.
I was running stock front and a 35T rear. New rear is back to the stock 34T. For the front I got a 17T and an 18T just to play with and see if it is too tame, or if it works well on the highway.
Anyhow, if you've ever wondered what the difference in diameter one tooth makes between the 34T and 35T at this size, its about 10mm
Spent a good couple of hours slowly opening up the exhaust ports and trying to get them roughly the same. I took more out of the sides, and shaved a lot of the excess off the guide protrusion, then quite a bit off the bottom curve opposite the guides (shortest pathway for the exhaust gases to take). Ran out of grinder stone bits so the one still needs to be cleaned up a wee bit.
Also took a fair amount out just behind the valve seat, but couldn't get a good angle for a photo.
Any feedback?
I've never ported a head before.
