Sweet thanks Awk08 , if your ever in North Georgia give me a shout, I will buy you a drink.
Cases are lapped, ended up using a sharpie to mark my progress.
main bearings, and piston are on the way. I still have to get a good base gasket.
Now that the motor is out , some other much needed TLC is taking place swingarm, came pivot bearings were cleaned and greased pins as well, shock bushings were greased under the spacers.
I have new axle bearings to take care of a little slack on the sprocket end, got to pick up a bigger wrench for that task.
I need to do the upper A-arm bushings at least, really should do the whole set.
I am seriously considering painting the frame and all the silver tubing If for nothing but longevity reasons.
I already repacked the front bearings when I put on new shoes
As far as the motor goes, a few more cans of brake or carb cleaner, and some replacement parts (bearings,clutch kit, gaskets, etc.) and the entire bottom end can go together all the way to the covers
The head is ready for Some KOR TLC in the form of a pumpgas rechamber.
The cylinder is close to ready as well.
The exhaust port window has been raised 1.2mm (gives low 180's duration iirc) widened by 2mm total the top radius has been increased slightly as well, as for the tunnel it was opened to the edge of where the exhaust gasket ends and smoothed along the length.
The transfer windows have not been changed (yet) plans include raising only the primaries by .5 or .6mm to take advantage of the earlier and/or more complete blowdown while maintaining the direction as much as possible, the tunnels themselves were cleaned up and opened slightly from the bottom , center divider is shaped like a kind of rounded V.
The intake windows were squared slightly and the casting smoothed out and given a tapered "mouth", the center ridge here is also a fat curved V shape. The area leading Into the boost port got about the same treatment, the AL was opened up a little toward the mains, the rest has a somewhat short bell shape, boyesen ports were added and directed as flat as possible into the transfers, directing them up into the transfers wasn't really an option, although I did direct the mouth to hopefully give a low pressure area toward the top of the transfers, when the charge is flowing. If i loose too much low mid power due to short comings in other areas I may well putty in the intake a bit to help lower rpm flow.
Reed cage, since I run dual stage Boyesen reeds and plan to continue to run them as long as I have the stock cage, and since the lower one is a solid reed that stretches all the way across the cage I see no reason to keep the divider in the cage, this may be the biggest benefit other than smoother throttle response.
The above will be run with an open airbox, mikuni vm28, and Toomey B1 handling the music.
When I go down in a minute to cut the center supports out I will get a couple pictures of my cylinder, one side is not yet a mirror image of the other, and many areas (particularly in the intake area) still need smoothing and a final finish be it glassy smooth or 80 grit rough. Constructive criticism is welcome.
