pm Godfrey(maybe spelled with two d's?)...member here...I cant think of his business name right now but I think he is in the site supporter section

the swirls will wear off in time, might take a long time and only where the pads contact

They can be turned on a lathe, but it requires carbide tooling and a proper lather with the torque necessary. I thinned and slotted mine on a mill.

Not a matter of torque. Rigigity and tool geometry is important, they really want to sing and vibrate.
very difficult to get a good finish, unless cutting both sides.
I think they maybe rough them on a lathe, then finish grind in some cases.
If you take the rivets out they may be easier to work with.

Too much chatter to get them right on a lathe, as mentioned grinding is the only correct option. How hard is it to replace the rivets?

754 · « **Reply #104 on:** April 28, 2016, 09:54:23 AM »

They change them to bolts.

Any ideas on someone in Canada, preferably BC, Vancouver Island, that could refinish them?

Shipping is a bit ugly on these due to the weight.

Got some more bits in today, chain guard, tank badges, swingarm, (really only wanted the double nipple guts, but it was a package deal) and a ribbed fender. Been really looking forward to the fender. Plan was to cut it into two smaller ones, but the lines are pretty spot on for the bike as-is. Might just keep it intact and mount it onto the stock integral brace. Shame to dismantle a perfectly good stocker, but I haven't come across a crappy one that I could cut up, or just the mounting brace already separated.

Still might just mount the fender to the underside of the lower triple for static clearance and run an aftermarket fork brace. We'll see as the mock-up goes along.

Here's the fender:

Well after two months of going round and round with the seat guy, I've finally got the thing. It's very pretty. It also doesn't have hinges and it looks like I'll have to at least partially remove the seat cover to install some. Anyone happen to have some hinges, (and maybe a keyed seat and steering lock while I'm at it) they'd be willing to part with?

I have learned my lesson. I will just pay my nice local upholstery guy the money from now on. Twice the price is worth it to not have to worry about some jerk-off in the land of Faraway taking his sweet-ass time and then finally providing me with something other than agreed upon. Could easily wind up paying the same amount if all doesn't go well and I have to bring this in for "adjusting". Kinda browns me off that he was getting so many good reviews over on DTT, really got sucked in on that one.

Like to get that frame kit installed this week, so I can hopefully run it up-island for powder next weekend before the swap meet in Campbell River.

I've always stayed away from cutting frames wanting the option to go back to stock configurations. If I'm finally going to do it, I'd like to do as clean a job as possible.

Can anyone suggest a pipe cutter that will do the job cleanly and relatively painlessly?

Killman · « **Reply #109 on:** May 06, 2016, 12:26:50 AM »

The PO's seem to have welded a tab over the original tank bolt hole. Anyone care to share a pic of their stock frame in this location so that I can use it as a guide as I try to cut off the added piece?

Stev-o · « **Reply #110 on:** May 06, 2016, 05:53:12 AM »

Tank bolt? You sure about that??

Killman · « **Reply #111 on:** May 06, 2016, 05:56:44 AM »

Nope, but it's dodgy looking welding, (matches the relocated hinges on the seat pan) and I'd like to get a look at an original frame to see what it should look like.

Stev-o · « **Reply #112 on:** May 06, 2016, 06:03:19 AM »

Post a pic of the area you at describing.

754 · « **Reply #113 on:** May 06, 2016, 04:02:08 PM »

When you were talking custom sidecover did you mean electrics side only, or oil bucket side as well ?

Killman · « **Reply #114 on:** May 06, 2016, 04:03:05 PM »

Just electric

Killman · « **Reply #115 on:** May 06, 2016, 09:14:16 PM »

Here's a few pics of the area of the frame that I was talking about.

seanbarney41 · « **Reply #116 on:** May 06, 2016, 11:09:19 PM »

the thing with the prongs is original, the thing with the bolt hole is definitely not

Killman · « **Reply #117 on:** May 06, 2016, 11:11:14 PM »

Thanks, that's what I figured. Anyone have a picture of a stock frame I can use as a guide when I take it off?

seanbarney41 · « **Reply #118 on:** May 06, 2016, 11:38:20 PM »

You are gonna need the rubber cushion that goes there. Get a new one from Honda. Once you have it on hand, its easy to see ho it works. Sorry, I don't have any pics.

Killman · « **Reply #119 on:** May 06, 2016, 11:40:08 PM »

I've got the rubbers. Just want to make sure I don't take too much off the top.

SOHC4 Cafe Racer Fan · « **Reply #120 on:** May 06, 2016, 11:59:57 PM »

Just grind off the weld attaching that tab to the piece with the prongs, which needs to stay.

Killman · « **Reply #121 on:** May 07, 2016, 12:06:08 AM »

Sounds like a plan. Just like to make sure before I start trimming bits

Killman · « **Reply #122 on:** May 07, 2016, 12:45:53 AM »

May as well post some pics of a little mock-up of some bits I did the other day to lift my spirits. Wanted to at least see what the new tank, seat, front fender and saddlebags would look like. Put on the place-holder stocker shocks I picked up for now, just to raise the ass up a bit. I'll be using the taller Konis for the real thing. Nothing's actually properly attached at this point, pulled them all off, except for the shocks, and re-crated them afterwards.
Been too busy with work to do much wrenching. Trying to clear some computer and bookkeeping stuff off my plate so I can get on with things. Hoping to run the frame, wheels and exhaust up-Island next weekend for some powder and ceramic.

The overcast really made that chrome look good in the pics. In person it's all pretty wretched. lol

Bootsey · « **Reply #123 on:** May 07, 2016, 12:58:11 AM »

I dig that seat, where's that from? Are you sticking with the ape style bars?

Killman · « **Reply #124 on:** May 07, 2016, 01:09:28 AM »

Thanks. Had the seat made custom by the Vietnamese guy in Socal on EBay. Looks pretty, but it took two months, and was a PITA the whole way. Looks like I'll be needing to peel back the cover and foam to mount hinges as well. Hoping it lays down as nice the second time.

Hopefully swapping out a set of 60's Tomasselli tracker style bars for the apes. There's a pic of them a few pages back in the thread, I think. If they don't work out, I've got a nice vintage set of Renthals I can throw a brace on.
