Is there any doubt re the engine starting??? We have faith in the good Doctor
Getting it together.
It is now ridable but I have a bit of paintwork and fairing repairs to fix.
Have a look at this cluster f*ck of repairs to the mirror mounts of the top fairing.
Didn't look any better when I got the fiberglass off (didn't have to try very hard) and had been glued with some crap as well.
I bought one of these hot air plastic welders from fleabay, but it blows too much air volume and when I get the plastic melted the wind pushes it out of the join. I tried squeezing up the outlet (just made the wind blow stronger out a smaller hole), restricting the air intake (motor got too hot) and even put a T piece in the line to divert 50% of the volume to atmosphere, still no good. I got my trusty soldering iron, fitted the flat blade and went back to how I have been doing it since the 1970's.
Is strong and should clean up with the sander nicely. Maybe get some paint when the weather clears.
Where do you buy the plastic fill from Murdo? Bunnings?
I did buy some of those rods from Bunning's, but I have an old Honda fairing (from my 1993 ST1100) that I cut up into strips about 3mm wide that I mainly use.
I've tried that with an old CB250 fairing and I find when it's melted it becomes really brittle. Do you have that issue too?
Is your hot air gun temp adjustable ?
If not you might be able to use something like this to tune it to what you need, or a better quality one.
Make sure it is rated to the maximum wattage of the temp gun and mount it inside a jiffy box too so you can't electrocute yourself
Some old sewing machine's have a similar circuit in them too, just make sure it's ac output as well.
No brittleness so far.
The temp is adjustable, but even on the lowest heat setting the wind speed is still the same. Will have to try one of those on the fan motor.
Got it all together and running now and polished up for the street show. Still waiting on a new seat cover and the 'zzr' stickers.
At the street show.
they look great Murdo
Nice job Doc, as per usual your bikes look awesome.
Got the stickers and the new seat cover on (still needs to shrink a bit) and borrowed a plate and took for an early morning ride. These don't go too bad at all.
Nice job, the orange & black work great . Very smooth to ride they are Indeed.
They are a good thing, trust it returns better economy than it's big brother. Looks good mate

Took it for a blue slip (registration inspection) today, bought a plate and insurance, and ready to ride.
Nostalgia has me wishing I could ride yours.
Well you could buy this one or my spare if you really want one.
Thanks for the offer but I'll pass, would love to ride one again for the heck of it but unless it was a 600 or 1100 I don't think I'd own one again
Took the little ZZR for a 120Km run today and am impressed with how well it sits on the road. It's a bit busy at 100Km/h (8,000 rpm) but seemed to climb hills ok. Only a small bit of vibration through the right handgrip. Think I will go a grade heavier on the fork oil, although the springs seem ok, to give a bit less dive under brakes and suit me better. Didn't even hurt my back too much.
They ride really well don't they ? I had one years ago, it was super steady through the corners
I miss Nix. I think I'll have to find another ZZR-250 once the current round of projects are finished!
