Today I drained the oil out of the oil pan and I pulled the neutral safety switch.  I was lucky to find a new o-ring at the local Honda dealer.  Got it all back in place, but it's still leaking a little bit, not as bad though.  Hope the oil will make the o-ring swell up.  I guess I could coat the o-ring with a little three-bond.  What a crappy design.

I also checked and re-adjusted the valve tappets as needed now that the engine has been run a little bit.  Nothing major out of whack.  Seems to run a little quieter and smoother though....or I might just be imagining it.

I got about half the gas tank polished.  It'll have to wait to be finished.  I'm going to be on vacation next week and in two weeks I'll be riding around the Texas Hill country, but not on this CB750.  I'll still have fun, but I really want to finish this bike and ride it.

Oh yeah...I also got a good look at a new CB1000 at the Honda dealer.  Really nice looking bike.  Would love to take one for a ride.

Yes, I found the ignition screws at Davis Silver Spares. Once I knew the Honda part number it was easy, they're not very expensive.

I got the airbox parts back from the powder coater, but I can't remember what I did with the set screws.  Gotta get some more.

The safety switch is still leaking so I bought a brand new one and another new o-ring.  Hope it stops the leak.

I'll be heading out of town for a bike ride this weekend.  It'll all have to wait another week before I have everything ready for the first test ride.

I've had some billet clutch lifter plates made.  I'm giving away five of them.  Details in the Free Stuff forum in the Classifieds.

I thought today was going to be the day I made my first test ride.  Didn't happen.  I had some trouble syncing the carbs, but I eventually figured it out.  Helps if you read the manual.  The bike sounds good and has quick throttle response.

I got the front brake bled.  All good there.  I just need to finish polishing the gas and mount it on the bike, put some gas in it and I should be ready to go.

There's three clutch lifter plates left...

First ride today.  Just did five miles on her.  The biggest thing I noticed right away was that she's totally unlike my other bike.  Who would have thunk. All in all I'm pretty happy.  I still need to do some tuning, but she seems like she's pretty close.  Gotta get it insured, inspected and registered before I can do any serious breaking in.

Thanks, Mike.  Feels great to finally enjoy some of the fruit.  I just retarded the timing a little bit and took it for another spin.  Takes off smoother now.

I'm calling my insurance guy tomorrow.  Got a buddy who owns a bike shop who will inspect it for me.  Then off to the DPS.  I sure hope they let me register the vintage plate.

Ya that is cool.  I have been looking for a decent vintage cycle plate for mine.  That looks perfect.  :)

I found that plate on Craigslist.  Just kind of stumbled upon it.  It's NOS.  Was never installed.

Now that I've ridden it I've decided to call the bike, or at least refer to it as "The Café Tracer"...café racer with tracker handlebars.  Works for me.

Congrats Bud, looks great.   Register it as an antique - you won't need an inspection.  And you can use the cool plate....

Thanks Steve.  I'm going to register it as a Classic.  With my luck I'll get pulled over 100's of miles from my house and I don't want to try and explain that I was on my way to ride it in a parade.

I got the bike inspected today.  After work I rode it to my buddy's shop.  He's the guy that gave me the bike in basket case condition.  He wants to buy it now.  He knows that if/when I do decide to sell it, it ain't going to be cheap.  It was his first motorcycle.  I really want to put some miles on it before I even think about selling it.

After a painful experience at the tax office this afternoon they decided they're going to let me run the vintage plate.

Now that I've got about sixty miles on the bike the right fork seal started leaking.  The seals came with the Cycle X fork tubes.  The left one started leaking during the build so I replaced it months ago, way before I put any miles on the bike.  I remember reading a post where somebody else had problems with the Cycle X fork seals.

When I replaced the left one I bought a set.  Now I have to remember what I did with the other one.   I know what I'll be doing Saturday.

On the K4 , drain oil on the offending fork, block up bike, remove wheel fender and brake if needed.
 Then remove allen bolt from bottom to get slider off..dont need to mess with lights and triple trees.
 Wayyy faster..

I pulled the wheel already.  I'm going to let the fork drain until I can get back to it on Saturday.  I'm running aftermarket triple trees.  It's not a big deal to pull the fork.  I have to pull it any way to fill it back up with oil.  Easier to pull the fork than to pull the handlebars to get access to the fork caps.
