Aussie 79 xs400 Build

So I havent actually don alot to the bike the last few weeks, I've ordered a bunch of new parts that should be getting shipped in the next 2 weeks like a new lithium battery, combo regulator/rectifier, new VM30 carbs new uni filters and mikuni dual throttle cable. Got new indicators and a massive front lamp from dimecity. So once its all delivered I've got plenty to keep me busy, good timing with 6 weeks of Uni holidays coming up.

Also I bought some new tyres on my spending spree, picked up Some Pirelli MT90 at/t's 120/80 18 rear and 110/80 18 front, i wasnt super keen on chunky enduro tyres but after seeing them on this xs750 I really liked them

This is also the kind of direction i hope to head in with the bike, clear frame, clip ons, fat tyres, hidden electrics etc. I should have all the parts soon so just a matter of doing the work to get it done
 
Still waiting on parts order, partzilla is taking forever to get my Mikuni Vm30's in stock, they've delayed shipment twice and pushed it back another month. In the meantime my new lithium battery and combo regulator rectifier got delivered. Currently in the process off tidying up my wiring and removing the battery box.

I'm thinking of mounting the battery on the underside of the fuel tank mount. It is pretty much a perfect fit up under there and should clear my uni filters. Also made up a new mini blade fuse box to replace the stock box.

Im using the stock loom and keeping electric start so there is a tonne of wiring to hide under the seat pan, I'm thinking of welding or bolting a steel pan underneath the seat rails and trying to hide as much wiring as possible in there and possibly mount the fuse box and Regulator/rectifier on the underside. Still need to make a frame loop and seat pan so its hard to visualize at the moment.

Sorry about the crappy pics my phones camera is slightly completely smashed. Also here's a pic of the new battery, its got 220 cold cranking amps, cant remember the a/h rating but it was definitely up to the task. I think they are supposed to be a little less sensitive to overcharging compared to anti-gravity and ballistics. Also they can only be charged with a 12v car charger. Absolutely no fancy lithium type chargers allowed

Gave the wiring a tidy up today, shortened the loom and recrimped and heat shrunk some connections. All wiring will fit between the seat pan and the aluminium sheet beneath, have the combo reg/mounted underneath the pan in the open. Thinking of nounting the new blade fuse box under there too for ease of access

Finished with the rest of the wiring. Replaced and heat shrunk most connections, wired in my new 7.5 inch headlight, new billet aluminium turn signals and mini speedo with LED indicator lights from dimecity. Ill chuck some photos up later. Had to hook in some diodes to get the single indicator light on the speedo to work.
 
New mikuni VM30 carburetors got delivered today. Also got new downswept uni filters that clear my hidden battery perfectly. Just need to sort a few little things before I start tuning them

Little update, getting tires mounted today. Going to rebuild the front forks and lower them this weekend before the wheels are back on.

After cleaning up the stock wiring i've decided to get rid of the electric start. I got a 2.5aH AGM battery that will sit in a slim battery box under the seat pan so I sold off my larger Lithium battery. I drew up a very basic plan (in ms paint haha) and got a mate to bend the box up for me, just have to weld it up

Make sure there is plenty of air flow around the battery. These need to be in a breathable area or they will overheat and fail. Also make sure the battery has a charge rate of 14.5 or more or you will fry it.

I was thinking of cutting some slots into the bottom of the pan to hopefully direct some air flow to the battery. I have an upgraded reg/rec but i havent had the bike running long enough to check the stator output, haha hoping that everything is healthy.
 
Went through the front end the other day, cut 3cm off the front for springs and added a 3.5cm spacer to the damping rod. Also changed fork seals and fluid. Used 15w and filled the forks 6 inches from the top.

Replaced the loose bearings in the headstem with tapered rollers from pyramid parts then bolted all the front end back up.

Started getting into my seat pan wiring, its all stock really but I've deleted the electric start and shortened wires for about the 10th time to neaten things up. Got the battery, blade fuse box and combo reg/rectifier mounted in my battery pan. Also moved the kill switch to a toggle switch under the battery pan. Still a bit to tidy as I dont want too many wires running around the heat sink but as of now it all fits

It would be good to still have a kill switch on the handle bars. If you needed to kill the motor quick it's a lot easier to flick a finger than to take a hand off the bars and reach up under you and feel for it:wink2:
