The ticky ... riding!!

Sounds like ........ I would like to see what you do about panniers. I bought a small cheap set that fit ok, don't hold a ton but I don't carry much so I think it will be ok. I carry most stuff in a 70L duffle on the back.

So here's an update on the pannier situation.

I got some old steel tubes out of a clothes hanger rack and some old parts from my old and now dead zzr, and bent them a bit to get them to where I wanted.

I drilled a small hole on one side near the pillion step/ muffler hanger. I think there was already a hole on one side.

Then i welded a nut to the red (looks rusty, but it's strong, mostly surface rust) pipe and attached it horizontal to the frame.

Then i took some mounts plate that i found online for second hand and made appropriate holes and bolted it to this pipe.

Some good (ingenious if i may be a allowed to brag) design on the way these are bolted. I made a hole, and slided a nut inside and then bolted the bolt to this nut.

The side pannier case mount plate is attached viab4 bolts as shown in green circles.

I made holes into the pillion grip and attached a carrier there.

The top case carrier is bolted to this carrier.

I bent the other two legs of the carrier so that it fits where the green circle is shown without any bolt currently attached. And where the indicators originally attach.

I shift the indicators shoddily to a horizontal pipe that attach to the two red pipes and made some extension wire to attach the indicators!!

It got dark as i was assembling.

A shoddy looking job but it seems to work. I'll take a photo of it all finished and cases attached soon.

UPDATE:
 
4500KM Twisty and Super fun tour to and fro and around Hokkaido (northern island of Japan) done!

Panniers workes great, no issues in storage and rain protection and strength overall, however, Cant leave the handlebars at 40 to 70 kph as they shake. This doesn't happen when the panniers are empty. Funny.

Also, one fine morning, the fuel pump stopped working .... in grizzly bear territory.. so had to take the hose and directly plug it into the filter instead of through the pump while being scared lol.

Now I either plan to keep the fuel pump removed and place an in line fuel cock to prevent flooding when I keep the bike parked for a while (as the under tank cock is hard to get to) or replace the fuel pump. I'm assuming any old fuel pump of a similar motorbike should work, as it's simply a cock replacement, correct me if I'm wrong though. A vaccum petcock may also work if I find one, though routing a vaccum line may be a bit of a pain


Others than the above issues it was pure pleasure on wheels for the past few days.

Got a fuel consumption of 19.3 km/L for the entire trip on an average (calculations full to full)

Nice tour! Kudos on the pannier mods. Good fix on the failed fuel pump. Many of us had to also do the same thing. We keep in our cubby's a brass barbed fitting to tie the fuel pump inlet/outlet fuel lines together.
 
When you get the replacement pump, resist buying the Chinese knock off pump. Ask me how I know.
Oem Yamaha pumps are the way to go.
The fuel pump set up is much more reliable than any aftermarket vacuum valve you could install
The 1984-'87 Yamaha FJ vacuum petcock won't fit your tank, it has a different base.
Access to get to the manual petcock is a problem, needing to cut an opening in your left side panel.
Now that you're home, just plug the fuel line until you get a replacement pump so you don't spill fuel on the floor of your garage. 
RPM has a great price on the Yamaha fuel pump: http://www.rpmracingca.com/proddetail.asp?prod=YamFPump&cat=39
