Here’s a really good practice. I coat the brake pipe (right above the flare) with a good amount of anti- seize, then run the flare nut down and spin it. You’ll be glad you did the next time you want to remove it. The threads on the nut get a coating too.

I put this together +5 years ago and it came apart easily…….

I put another very thin coat of the Bosch brake grease on the steel backing plate for the new pad, where it runs in the bore too.

All back together and bleeding in fresh DOT 3 fluid is next.

Note my “helper” sleeping in the back of the golf cart. That’s how she ensures I don’t go anywhere without her!

 Bled the brakes today with my new Mity-Vac (the old one fell apart last time I used it). Great tool, improved over the old one with lots of nice hose end adapters. Done in a few minutes…..

Adjusted drive chain tension and almost done.

Took the bike up and down the lane and it ran a treat. Ready to cover it up when I spotted a bit of dampness around one of the fuel lines to the petcock. Drained the tank via the other spigot and sure enough, as soon as I touched the suspect, it popped out of the petcock.

Tank off and a drop of JB Weld to the rescue, will put it back together tomorrow.

I also installed the little drag shoe that goes under the knurled (and spring loaded) knob that screws into the underside of the throttle switch control housing. It’s used to add tension to the throttle tube and can be handy when warming up the bike or as a cruise control. I usually leave them out as they seem a bit “iffy” as an engineered solution. The owner wants to try it, so there you go. We’ll see. Easy to remove.

Is any project ever really done?

No, never!   And that's why guys who dont like to turn wrenches buy modern bikes and cars, just turn the key and go.

[MauiK3]

I don't have the drag shoe, anyone have a photo?
No, these projects always have a thing that needs to be done. I suppose many of us like it that way if we are honest.

   Truer words could not have been spoken. Don't get me wrong but to own anything "vintage" (whatever that means these days) is an endeavor of enduring maintenance. So many want to own these bikes but simply haven't the skill set or the patience, let alone the time required to learn and do it. If it can't be done on your cell phone, it simply isn't going to happen. We grew up with wrenches and desire and time, many today just don't have the attention span let alone the desire or time, it takes to develop the skill set needed. When my last employer needed to hire new employees, we actually had to have a class on how to use and read measuring devices, like a tape measure, we constantly reminded new hires that what they needed to learn, wasn't on their cellphone.

Steve(s) and Mark…… That’s why I like to share with you guys. Most of my friends (other than the guys I race with), don’t get it!

Steve….. These are only on the early bikes with a single, “pull” throttle cable that then splits into 4 cables that pull directly on the carb slides. Horrible arrangement to set up and tune, so Honda quickly went to the mechanical “bridge” that opens the slides.

In this early parts drawing the drags shoe is part #13. It fits inside the housing, in a recess, under the throttle tube. It’s a LOT smaller than in the drawing. #15 is a knurled knob that screws into the housing, directly under the shoe. As you screw it in, it jams the throttle tube in place. #16 is the external spring that stops the knob from self adjusting. The theory behind the design (and shape of the shoe) is that you can always shut the throttle down with the grip……

I never liked it and usually don’t install the shoe. I polished this one up nicely and applied some lubricant. It certainly was very handy this morning, when warming up the bike!

Put the gas tank and seat back on, after repairing the petcock spigot yesterday. Seems to be “all done” (for now). The Yamiya “body set” is truly stunning work.

That throttle screw and shoe appeared on bikes at least through K2.  I hate 'em too and always discard on any bike I will be riding.  It seems most all they do is cause extra corrosion that inevitably gums up an already too heavy throttle.  And cruise control?  Anywhere it would be safe to use cruise control on a motorcycle is not somewhere I want to ride one.

Agreed. Will wait to see how this one works for the owner.

Going though Kansas trying to get to Colorado sounds like a good place for cruise control, although I haven't found one that feels safe enough to use on a CB. I do like those palm paddle things, that seems like the best option for a CB, for me personally.

Nice bikes Benelli.

The throttle tube tensioner/cruise were on 1969-1974 K models.

I stand corrected. Have a safe trip!

Funny, my 1970 K0 had one. My current K3 has the knurled screw but no shoe (repro parts).
On one of my coast to coast US trips back in the day I used it in the desert a lot. I always liked cruising in the desert, especially at night.

Thank you John.
We are going to Grand Canyon today, in the cage....

[BenelliSEI]

Never done! Loose “jewels” in speedo and tach! Covers came off too easily. Some good adhesive and careful application should do it…..

[BenelliSEI]

Finished it up this afternoon. JP should be back for it next week.
