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.

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.

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...

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)

That's not a lack of air cleaner issue. It'll be a big air leak or the throttle slider is being held open (either not sitting in the slot right or a bunch of shit holding it open.... or a sticky throttle cable). 

They need an air box/filter, but you'll only notice it when under load. It will start to cut out under load from being lean. All you need to do is grab some air filter foam from a bike shop and make up a new element (the bike shop made one for Rahn's FZ in about 10 minutes). 

Come at me if you want any tips on making Suzuki F's go OK.

Those have “49cc” cast into the cylinder and no one will ever know it’s 60cc anyway. It still won’t be fast, but at least it won’t be so slow :P .

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

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?

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

Mine is a 4 port tap. Not sure if one of the ports is not totally necessary.

Yeah fourth is just vacuum so it will only flow when running (IMO just another thing to fail, handy if you forget to turn the tap off tho)
