Sounds great!

I thought I’d make one more video before tearing the bike apart. This one deals with carb syncing with a manometer.



This manometer has a relatively large body of water, and the vacuum lines are fitted with a .6mm jet. This has the effect of slowing down the movement of water stabilising the readings and making the device extremely accurate. Just a miniscule turn of either idle screw or throttle adjustment screw greatly effects the fluid levels.



I have great trouble with my fingers, so you'll notice me changing hands frequently trying to turn the adjustment screws. I also turned the adjustment screws the wrong way a few times, putting the levels out.

You sure do know what you're doing...

This is a new brake divider I machined up to replace the original. The original hoses were rotted, so I replaced them and did away with the two steel tubes that connect the hose to the calliper and the hose from the master cylinder to the divider. Unfortunately, the new hoses have the banjos on the same plain requiring the lower hose to be twisted through 90degrees to connect to the original divider, so I machined a new divider to get around the problem. The lower hose connects at the rear of the divider, as does the brake light switch. The top hose connects to the side of the divider.

A few hours is all it took - it's just a pile of bits that once was an almost complete bike now, just needed tyres and the seat covered. Going to be a big job polishing all those bits again, any volunteers???

A couple of mods on the frame to do: Remove the coil and flasher mounts then repaint along with tank, guards, seat, trees and a few other bits. Not sure what paint to use this time. I used acrylic lacquer last time, but spilt some petrol on the tank and it stained it. Painted heaps of tanks with acrylic lacquer before but never had this problem, either the paint is different or the petrol is. Don't really want to repeat the exercise.

Could it be alcohol in the fuel?

Not from a service station.

Applied the final coats of acrylic lacquer to the tinwork and some ancillaries this afternoon, didn't come out as clear or as good as I hoped, but acceptable I guess. I'll give it a few more days then sand the tank and spray over with 2k clear. Not the done thing, technically, but plenty do it, so we'll see how it goes.

From what little I still remember about painting with lacquers was there was a lot of rubbing to ever get the shine to really pop.

Depends on your technique. The tinware in the picture is straight off the gun. This was my first paint job on the tank, again, straight off the gun.
