I don't mind the questions at all, actually appreciate the interest. I managed to get info about the felt seals from the tech section. I got all, accept one, out without DAMAGE. I broke one, which I hope a small dob of glue might fix. If I rate how I feel about the paint job on the carbs 1 being very disappointed and 5 being very happy, I'd give it a 3 satisfied ( just). I have to remind myself that I'm a novice and quality of work that I'd like is beyond my current experience and abilities. I made some noob errors in the painting process, got some runs and shouldn't have heat cured between coats, as I put the second coat onto a heated surface and stuffed up the finish. I could have tried another coat, but felt that the way I've been going, I'd probably make them worse. I used VHT high temp paint which is chemical, oil and gas resistant, hopefully that covers fuel. My plans with the engine is basically black with polished side covers, breather cover, valve tappet covers and head side covers. I may look at taking the paint off the fin edges as well. I've got the chrome starter motor cover and points cover also. I'll run the 4into4 original pipes to start with, but hope to make some of my own down the track.

Just thought I'd show how I removed 6 broken bolts from an aluminium fork top bridge(not off a sohc4)
After getting 2 out I thought I'd take some photos of the steps I took to remove.

Build up, by spoting with the mig.

Place on a nut

Weld nuts

Give nut a tap with hammer while red hot.(No need to be too heavy handed)

Heat aluminium with propane torch.

I didn't get a photo of the ring spanner. As I undo, I'm careful not to put too much weight on the spanner in either direction. A little each way, back and forth. Light hammer at end of each direction.

Sometimes they come out first go(rarely in aluminium), but more often than not. Second was the best on this one. One took me up to four attempts

This next one couldn't be removed by unscrewing, so I had to screw it all the way though.

Thread didn't like it at all. 2 options are to fill it with weld and redrill and tap or larger thread

Hi all,
I'm just in the process of reassembling these carbies.
Can anyone give me some tips on installing the mainjet holder. When I removed them, they required some pressure to get them out. What's a good way to push them in? I've put some pressure on this first one, but I've been reluctant to put more pressure.

Any thoughts would be much appreciated.

Mainjet holder installed,with a gentle tap home. Checked float height, 26mm. The service manual states 22mm as standard. Do I need to adjust mine to suit, if so how?
Just spent 30 min trying to fit a new o-ring bowl seal, I can see they'll be aheap of fun. I'll have to search for some tips on installing them, I've seen some tips in the past, using Vaseline or grease.

I'd say leave the float height at factory spec to keep them from leaking.

I think at 26mm, you're actually keeping less fuel in the float bowl than recommended. pretty sure that the higher they sit while upside down, the quicker they'll trigger the fuel cut-off (do i have that right? it's monday....). might not be a problem, but it could cause some issues when going heavy on the throttle.

Hey guys, can anyone tell me if and how I can remove the throttle lever shaft from the carby mounting bracket?

kghost · « **Reply #56 on:** July 19, 2013, 12:47:44 AM »

Dunno,

I broke the last one I tried......

Damage Inc · « **Reply #57 on:** July 20, 2013, 11:17:43 PM »

Thx kghost,
I'm all for "learning from others mistakes" if I can.
As there is little feed back, I'll err on the side of caution.

My work neighbour brought his trumpy in today, hadn't seen it for quite a few years. This is the bike that inspired me many years ago, to one day do a café build.

I like this bike, wish I had spare coin as he is going to give it a polish and hock it.

Damage Inc · « **Reply #59 on:** September 27, 2013, 03:42:33 AM »

A bit of frame work.

Triple tree top bracket is ready for paint.

That Trumpet is lovely.

Damage Inc · « **Reply #62 on:** October 09, 2013, 02:14:12 AM »

Yeh Lester, it's up for sale now. He's got it advertised for $15,000 AUD. Some have said that it's too much. He's had a couple of offers at $8,000. I think he'll get around $12,000 if he's willing to sit. I'd buy it for fifteen, accept I've got about a dozen other things that I'd spend that coin on first.

Finished fabricating my bike carrier, just needs a paint now

Started on the seat mould today.

Thx guys, I appreciate the compliments.

Damage Inc · « **Reply #68 on:** October 20, 2013, 03:30:52 PM »

Mould shaping just about there.

Damage Inc · « **Reply #69 on:** October 27, 2013, 11:21:01 PM »

Put a wax coating on mould

Glass goes on next.
Taped up some parts ready to paint

Damage Inc · « **Reply #70 on:** November 07, 2013, 10:32:22 PM »

Other than a repair job on an old Canadian canoe, this is my first attempt at fibre glassing.
I'm happy with the progress, so far. 5 layers of glass.

Would love a fairing like this one.

For something as large as a fairing, I'd go with Air-Tech Streamling.

I hearing you! I would consider having a go at a cowling which goes under the frame and around the pipes and perhaps a little bikini fairing( if that's what they're called)

Removed the seat cowling from off the mould and started shaping it
Still plenty of layers required.

Hey guys, can anyone tell me if and how I can remove the throttle lever shaft from the carby mounting bracket?

It is keyed. The keyed section is hidden behind some seals. The seals were little metal cups with a felt washer. If you just beat it out, the key will rotate a little and "cut" right through the thin seal. The shaft pivots on bronze bearings.

Hard to explain, but I hope that helps.

Thx, that does help. I think I'll leave it best alone. I had been thinking of re-chroming the shaft, plating the steel components and polishing the aluminium. Found it very difficult polishing the aluminium, with all the ridges in it. I'll probably paint most of it now.
