Little time, so little progress, but progress nonetheless.

Crank drain and oil galley plugs, I showed them the least love when it came to prep work as I didn't wan't them too shiny and guess what, I can't take a pic without them blinding the camera! The levers, I sanded off some deep pits then quick incremental wet sanding rounds, they came out alright.

I might suggest this on the levers: when I did that with mine, they kept turning my hands black when riding. It never got better until I "sealed" them (for lack of a better word?) with Simichrome polish. When I used that stuff, the rags came out black from it, but the levers quit doing it to my fingers.

After I finally wore out the levers (pivots) I got new ones, with the clear plastic coating on them. That works, too!

Mark!! I'm glad you're still subscribed. I've sealed ALL the pieces I've done so far with White Diamond Metal Polish per Ryan/73Nancy's recommendation, that stuff works great. Same thing, while it makes the final finish slightly dull, the rags come out black (excess polishing compund??) but the final buff cloth remains spotless.

Finally finished sanding the new dyno cover. Acid burn is a terrible thing. I sanded so much off due to how deep the burns were, its now a performance part, lightened and all

Replying to a post on the last page, I used Teflon paste on my head studs on my last build. No leaks after about 8000 miles.

And finally, here it is. Project Ice Cream, officially done with reconditioning every last bit. Now, moving on to slow assembly of little bits over the winter, then full throttle next spring.

Forgot to note, the oil based paint sharpie still hasn't showed up, that's what's I'm going to use to fill out the black background on the Honda logo and the rim around it.

So this happened

Need a K2 tach now, paged Bill already, anyone else have one?

On their ride home to me

just my rotten luck.

Still no luck with a replacement, anyone have a K1/K2 tach stashed away and willing to help? Even a parts one will do as long as the core is functional.

edwardmorris · « **Reply #787 on:** December 24, 2014, 05:54:00 PM »

Gauge issue sorted, ended up using a parts tach to fix it up, caused a little scuffing and scratching on the outer housing, will need some touch up paint.

In the meanwhile, started putting little stuff together, starting with this carb back plate. DIY zinc has been holding well, fingers crossed

edwardmorris · « **Reply #788 on:** January 17, 2015, 04:22:33 PM »

Ah, the one step forward another one back phase! Started putting the controls back together and had a nightmare getting those pesky springs and balls to stay in place. Thankfully, my beautiful wife who has much better dexterity helped me out and we got the left hand control done. Nice new sleeving from vintage connections, just need to dremel clean the bullet connectors before assembly. I ran the turn signal buzzer shut off in its own sleeve in case a future owner wants to get rid of it, should be able to do a tiny bit easier.

As for the one step back, began working on the RHS and stumbled at first step. After painstakingly installing that kill switch circlip back in place, something was off, the kill switch didn't feel right and sure enough, I have the wrong one

BILLL!!!!!!!!! HAALPPPPPPPPPP!

seanbarney41 · « **Reply #790 on:** January 17, 2015, 04:50:55 PM »

lol, that is just the sort of trick Honda loved to play! It seems like the correct switch has to be one or the other. You should be able to look at your housing and see which is correct. I am guessing the shiny new, or refinished one that you have is not the correct one.

edwardmorris · « **Reply #791 on:** January 17, 2015, 04:52:52 PM »

Indeed. The broken one on the right is the correct one, shame that it was damaged during shipping (2nd thing on the project hurt by shipping

) I didn't even think about it till I started putting them together. If anyone has one, I can trade my nicely finished one!

edwardmorris · « **Reply #792 on:** January 17, 2015, 05:57:51 PM »

Its nicely detailed in Mark's book, I should have paid attention, oh well live and learn..

edwardmorris · « **Reply #793 on:** January 26, 2015, 07:17:09 PM »

I was saving this for later but gotta keep up with DaveZ

edwardmorris · « **Reply #794 on:** January 26, 2015, 07:17:43 PM »

Got em from CMSNL last year after the fiasco that was my attempt to save the old set.

Way to go my man! Looking real good. Finishing up your box today, I'll be in touch, Bill

edwardmorris · « **Reply #797 on:** January 27, 2015, 08:52:12 AM »

Thanks! I felt like this build deserved it, considering how many NOS or near NOS items are going on it. Came at a costly price of non stop work for weeeeks!

tweakin · « **Reply #798 on:** January 27, 2015, 06:40:21 PM »

Great work here! That zinc plating looks really good. I decided to go with CRs for my K1 so my rebuilt stockers might be up for sale soon if the zinc plating doesn't hold...

edwardmorris · « **Reply #799 on:** January 27, 2015, 08:44:32 PM »

Thanks Tige! I'm all set for this one thanks to Bill, although my K3's carbs are a total mess. I might just take you up on that.
