Agree. Nothing wrong with a bronze bush there.

Save a shit load of money to

Seat is all mounted with new brackets at the front, spent most of the day on the front wheel, I had to grind down all the spoke niplels and give the spoke holes in the rim a little grind as that rim is drilled for another hub, i highly recommend using the correctly drilled rim unless you want to waste time. 

When lockdown finishes i amm off to the brittish bike parts library where i can exchange stuff for more parts

Split the crank on the engine I am going to use because the big end felt rough, no wear at all but lots of moisture damage, in my experience they don't last long at all if you try to run them like this, so I had a back up crank pin I could use but under close inspection it has had some kind of failure like it was too soft or something. 

I give up.

Engine plan mk4, I got a Norton Big Four 630cc, its from the NZ army, they had 3 of them back in the day, it fits this frame but i will have to grind the bottom of the frame to fit the drain plug 

[SOHC]

Indian made 16H fuel tank, got it from my old work, this is %50 of the bike I reckon.

[GregT]

Engine plates from 6mm MDF - then copied in 5mm steel or 6mm alloy plate.

My own sequence is cardboard - MDF - alloy.

what did the nz army have them for, sidecar dispatch riders?

It was from a 2 wheel drive sidecar outfit that would carry alot of stuff and a brengun, nz army only had 3 of them, they have an odd frame for the rear axel witch would be impossible to find.

Yes I have some alloy Domi engines plates i will copy the rear half and get the holes marked for the frame witch will make it even easier, engine bottom crankcase though bolts line up perfectly with the frame holes

[SOHC]

I forgot i had that front guard and I found a rear, also found another frame that has had one of the rear engine mounting lugs hacked out to fit some  other engine that may be better to use as I may need to do that anyway.

[SOHC]

Had to cut the rear lower engine mounting lug and move it up, and cut the front lugs down. All the frame mods to fit the big4 engine are done, just need to make the engine and gearbox plates.

I got a roadholder front end, its an early one, stripped it down and with out fail its fucked, I had some commando staunchens but they are too short, so have ordered some longer ones, some new bushes and seals should see it working again.

[SOHC]

I got rid of the later alloy hub wheel I had for this ealy one.

Devcon - and sand it down. Not too bad a bodge for a old/slow road bike but I wouldn't use it for anything seeing a track.

A new pair is $250, I have ordered them and a fork rebuild kit, got some McIntosh steering head bearings to, front end is going to be very nice

[SOHC]

Started welding up the cracks in the rear guard.

[SOHC]

Rebult forks with new bushes and staunchens, way more work making things fit and work because of shitty reproduction parts.

[SOHC]

Fitted new custom made tool steel steering head bearings and the front end, I am not going to use this frame as its a but shit, I should have looked it more, I have another one that looks way better.
