Voted. I'm comin.

@SunnyCoupe you keen??

Fuck yeah fizzing! 

@Carsnz123 dropped a 6v bulb he had spare to me after work yesterday. Fitted and all works 100%.

One thing did bug me though, with the headlight on there was no tail light only brake would illuminate. Got home today to check bulb and looks someone in the past has jammed a 21w/12v bulb in there. Which was a single filament and double contact bulb lol. Will get the correct 6v bulb and then everything should work properly haha.

With it running much better it was time for a proper fang down the street! Borrowed a helmet and went round the block a few times. My fiancee loved it and she didn't want to give it back! I'll have to get another one now....

The electrics weren't 100% to start with. Indicators would illuminate but not flash. Figured out the front brake switch wasn't snug in the lever assembly. Got that sorted and indicators now flash. Now to sort the ignition switch. New switch from E-bay was 7 wire, 6 wire plug with a seperate blue and white wire. Old fucked switch from blue bike was 6 wire, 5 wires in plug with seperate black and white wire. Removed the black and white wire from the plug in new switch and connected to earth,  figured there was a black and white wire on old switch and no blue and white wire haha, disregarded the blue and white wire and everything seems to work alright and ignition is cut when switched off.

Pretty chuffed to have it pretty much all working propely!

I've been working on this a bit lately and have it running pretty well!

Took the exhaust off and went for a fang up the drive and went way better than before. Exhaust was suuuper clogged. Ended up snapping a bolt in the barrel as I was just going to put it back together.... Borrowed some left hand drill bits from work and ran my tap through the hole. The exhaust on the blue bike didn't feel as clogged so thought it was worth a try. Replaced exhaust flange gasket and started her up. Fuck yeah she goes good! 

As you can see the exhaust from the blue bike is a bit barry spec. Will sort that out at some stage but is doing the job just fine at the moment haha.

Couple more vids with it running much better now.

Couple videos.

 A few weeks back I scored this much more complete green FZ50. Main things missing were trans cover, kick start lever and ignition switch. I had all these things from the blue FZ so spent last weekend swapping them over. Kick start on blue bike was welded so had to cut that off so I could remove the trans cover. Got everything fitted up but needed a kick start lever. Took a punt on a cheap one on trade me and took me a while to realise  I had to use a smaller bolt to get it to work as the m8 bolt that came with it was too big for the slot in the kick start shaft. 

Filled tank with fresh fuel, kicked over and putted into life. Let it run for a wee bit and went for short blat up the driveway. Is woundingly slow but I don't think it's running all that great.

I have a battery for it just needs charging. Something funny is going on with the ignition switch, can start it with key in off position, won't  turn off when turned to off position, the headight turns on when though when key turned to that position. New switch had an extra wire that the plug on the bike didn't have, will have to take a better look.

Pretty chuffed that I had it running pretty easily. Just need to get it running better and go for a longer fang!

I've been fluffing around with this for a while. Got the fuel tank set back up with the new tap, filter and fuel lines. New ignition switch arrived from Ebay. All I had to do was reassemble the motor and try starting it again. But ended up breaking a piston ring which isn't a huge deal but I'm not going any further on this one.

Things have been a bit quiet on this as I've been working on my 180B (like I should be..) but things are starting to come together! A while back I gave my cylinder to @JustHarry to see if he could repair it. Dropped it off to me Tuesday night and I'm bloody chuffed with what he did! Going to hone cylinder and reassemble with the new gaskets I got a while back.

Fuel tap and filters from Aliexpress arrived today too. Will be a bit of fluffing around to mount tap to tank but won't be inpossible.

Get the 3 and write on your tank/key chain to remember to turn tap off. A failed tap will dump fuel into the engine and fill the sump (worst case, but happens, habit of turning it off is free)

Thanks for that, good idea! Just purchased that fuel tap and a couple fuel filters.

Oh sweet I may get that 3 port tap and see if it will work!

Thanks man I've got an FZ manual on my phone already but the others will come in handy too. Cheers.

That looks to be a fa50 tap, which are vacuum operated iirc. Fz are gravity fed taps, you should be able to find a chinga replacement for $10-20 shipped if you browse Ali or eBay 

You reckon? I've had a bit of a look but can only find spenny ones on ebay. I'll keep hunting... 

Another thing I will need to sort once the tank is finished is the fuel tap. The one that came with the bike was in pieces when I picked it up and my mate gave me another one that looks similar but is completely different... any ideas?

It does look woundingly slow. 
The last time I ever rode my NQ50, a lycra fag on a push bike passed me on my way to work. 
I retired that bike that day.

I'm not looking to go super fast. Just have some fun and learn more about 2strokes etc. 

Emptied the fuel tank to see how she's looking, and damn she's looking good!

I'm going to get more Metal Rescue and fill it again and seal the top up better so I can leave it upside down to better get rid of the rust that's still there. But stoked with how good it's looking.

Removed the plastic filters from the tank outlets. Anyone know where I might find some local? Seem quite pricey looking at ebay etc.

I've also removed the fuel gauge and float. The gauge had clear tape all around and over which wasn't very clear anymore. Will try and fix it so it's visible or find a new one if not too pricey

Get one of these up ya: https://www.treatland.tv/suzuki-FA50-45mm-cylinder-kit-p/suzuki-fa50-45mm-kit.htm 

60cc and should be ready to bolt on and go. 

Hahahaha yeah that is plan B. Although I'd want to get it road legal so standard to start with.

Thanks man! Currently have the issue of broken cylinder to deal with before I can start it again....

Just a thought.
was it running with no air cleaner in that vid?
Two smokes are jetting from the factory to have an air filter on. in my experience running without one they'll be a bag of dicks/not wanna go any good. (I had one that wouldnt start with the airbox off)

Yeah no air cleaner... have air box just need filter. 

Full of enthusiasm I was excited to get this up and running again. Got the bike raised up and sitting at a nice workable height to remove the cylinder so I could repair threads for the exhaust.

Got it apart super easy and attempted to drill and tap the bolt holes from m8x1.25 to m10x1.25.

Got one hole done and was looking pretty good. Drilled out second hole but my tap just didn't want to start cutting... I tried and I tried and nothing... even put the tap in my drill and went slowly to see if that would start it off but nope.... swapped to m10x1.5 tap to start the thread which appeared to work. Swapped back to the fine thread tap and attempted again. When disaster struck.... the casting cracked...

I was so gutted. It was all going so well!!

A mate is going to attempt a repair but we'll see how that goes...

A week later I had a look over it and my flatmate was adament we should try and start it. Removed fuel tank which was full of rusty shit, it had been quite sometime since this was last running... changed gear oil, cleaned up spark plug, topped up oil tank and fed some fuel to the carb. Kicked her over and fired up on the second go!  Here's a short vid, excuse the laughing....

As you can see very smoky... the exhaust was only secured by one bolt and previous owner had used some tie wire to hold the rest of it up.. attempted to fit a second bolt but hole was stripped... lame.

Here's the crap that I shook out of the fuel tank... have currently got it filled up with Metal Rescue to remove what's left of the rust. It's been sitting for about a week so will empty it soon and see what it looks like.

I had been looking for a 2 wheeled project for a while and this came up for sale cheap on Trademe. It was in Nelson but I was heading to Blenheim end of March/start of June. A fellow Datsun club member (and may be on OS too) picked up and stored for me before I was able to mish up to get it. Picked up over Queens birthday weekend and got it home.

Is missing quite a few bits but hopefully shouldn't be hard to track those down.

Hahaha excellent! I really need to update the thread. Not much has happened but I've been accumulating parts.

Haha yeah could do.

Yeah it’s the latter I’d be more concerned about if I was him, but as Luke said, I have to go hahaha. Setting my expectations low, doesn’t really bother me if it’s any good or not, not obliged to stay there for any certain time. If it’s lame I’ll just drive a whole 10 mins home haha. Just an excuse to get out of the house/chores for the morning.

Hmmmmmmm decisions decisions.
