 The rest of the wheel/axle spacers were machined up.



 The top triple has been modified and the key switch hole machined off. Custom dust cover machined for top race.



  Top bridge drilled for bar risers (CB350 twin) and gauge mount attached.



 I hope to get it back this week. If I do, I can start on freshening up the forks and making stuff pretty.

Started working on some 400F pegs while I'm waiting to get back all the stuff I dropped off last week. Still need to modify the heim joint on the shifter and modify the brake lever.

Got the frame home yesterday. Wedged in the fender I hope to use, just to see if it would work. Looks like it'll be easy to make it fit.
 The bars clear the fork adjusters easily (those are not the bars I'll be using, though).

 Spent some time doing disassembly and working on the non-glorious stuff, like cleaning up random bits and pieces and hardware. Plenty of time with degreaser, Simple Green, EvapoRust, wire brushes, etc. Most people will never see this stuff again once the bike is put back together, but I'll know that every single bit has been touched, cleaned, polished or replaced.

I modified the brake pivot to work with the 400F brake lever. This gives you the proper ratio with the shorter foot pedal.

Got the head all cleaned up and installed the new valves. Decked .020 and 1.00mm over intakes, new exhaust valves.

Stripped the frame to get it ready for powder coating. Dropped off the swing arm to have the inner sleeve and shock mounts pressed out. New bushings will go in after powder coating.

 And here's a picture of the front Lester with FZR600 rotors and the spacers to make it all fit the R6 forks. Just because I think it's bad ass!  :)

Cleaned a few more batches of hardware. Also cleaned up the Lesters. I've painted/polished them before, and I had my Henry Abe's powder coated, but I decided to do more of a "sympathetic restoration" on these. I didn't want them too shiny...and I didn't want to deal with all the taping up for paint. They're in pretty good shape, with the rear being the worst. It has/had one spot of flaking paint and a few little spots of surface corrosion (no pits, just discoloration).
 I cleaned them with car wash soap, followed by a few passes with Purple Power and varying grades of SkotchBrite and fine steel wool. I'll go over the lips again with some 0000 steel wool and aluminum polish. The plan is to get a sheen to them like they would have had right out of the box.

 More "invisible" work while I wait for parts to get back.

 We replaced the shift shaft seal (say that 3X, fast). Also honed the cylinders...



 ...and modified a cam cover so that I'll be able to degree in the cam.

 And one thing that's often overlooked is servicing the starter. In the past, I've experienced sluggish starter operation, and cleaning the starter really makes a big difference.
 Here's the "before" from this bike:



 I neglected to get an "after", but here's some pics from a different build.

 Before (nowhere near as bad as the current build):



 After:

 Got the 400F shifter heim joints modified and installed dust boots on the set I'm going to use.
