The Suzuki Stinger

Man, that's cool! Now you've got me wanting to turn it into a full on vintage racer.
 
while interweb browsing i found this.. i'm in NZ too, and i've just been restoring/turning my T125 into a racer. on the home stretch now, i can definitely say it's worth it! great little bike. awesome to see someone else has one, and in New Zealand too

Hi, Jaquesy.

I would love to see some pics of your Stinger. I also have a question. I'm just wondering if it is safe to run these bikes on premix, without modification. Or do they require the posiforce lubrication system to stay in place?

Oh, and for anyone following this build, it may be a couple of months before I get back into it. I'm just getting the NSR running sweet first.
 
I can understand the focus on the NSR!
After the sorting comes the riding, but don't forget the Stinger waiting in the workshop.

Crazy
 
sure - pm'd you.
not sure about the premix question, my posiforce system worked fine so i've never looked into it.
to be on the safe side i wouldn't, but then it's quite hard to find any parts if the system has broken on yours...

I don't think my system is broken, though I haven't had the bike running yet to check. Was just curious really, as you have turned yours into a racer, I thought you might have gone to premix.
 
My sister had a Stinger for years, my brother has it now plus another for spares.
Good find on the ad for 'Wolf' the only difference I can remember is Stinger had black exhaust with chrome tips, Wolf had chrome exhaust with black tips (I'm sure I already posted this?)
 
Looking like a real challenge!
Hey, I saw the dealer sticker on the back, not sure who they were then, but I work for City Motorcycles (The Pacific Motorcycle Co.) in Vanguard Street, Nelson!!
 
Just noticed the 'pre-mix' question
It's NOT a good idea without some mods to crank and crankcase
the pics you posted of failed main bearings show the 'cup' that feeds oil to big ends, it works by using oil that was fed to main bearings which gets centrifuged outwards,collects in lip then fed through a tubular section direct to big end,
It works incredibly well (Honda use an almost identical system on various motors, CB350~360, CB125~250T,etc)
Main reason for bearing failure is running pre-maix without removing oilcollectors then grooving crankcase to allow oil in

Excellent! yeah I can't quite make out the whole label, but it's ' ??? B. Motor Cycles '.

Interesting, I had no idea there was a tube running internally to the big ends. I'll have to dissect the old crank and have a look.
 
Crankpin is drilled like on a four stroke, the 'slinger tube' is probably 5~6mm long (it's a long time since I did one)
 
Still chipping away at this project. Assembled the bottom end this afternoon. I ended up getting some new cases to replace my damaged ones, and cleaned them up with a water blaster.


 
Right, I'm seriously getting back into this project now. I've spend half the day stripping the rest of the bike down to a bare frame. Here it is partway through stripdown:



I was also keen to try rust stripping with hydrochloric acid. Man that stuff is nasty, but it sure removes rust. Here's the chain before and after a brief soak in the strong acid.


 
HCl works a treat on rust, but as you say nasty.

If you aren't in a hurry a better rust remover is molasses and water in a 1:8 or 1:10 mix or thereabouts. Brodie (on this forum) was going to give it a try but I haven't heard how how went.

I've used it a few time myself and can vouch for it!

Crazy
 
Yeah I still have to give it a go. A friend swears by it and I can say I have seen the results and it does work.
