Personally I wouldn't use them for my kids bike.
For my self I would, but I would also be cautious.
But that is just because I am a cheap bugger.
Old tyres get hard and layers delaminate when they are heated up too much.

I know, and will likely replace them just for this reason. It just sucks to throw what look like perfectly good tires in the bin
 
First round of vinigar dump. Yuck.

Redneck ultrasonic. Big jug carb body and pinesol. Small jug all the brass and carb cleaner.

Float bowl final soak with carb cleaner to get the last of the varnish.

Brass all cleaned and compressed aired and copper wired these things were yuck yuck. May buy a carb rebuild we'll see but i got cleaner and ait through all the parts.
 
Jesus Murphy all that shit came out of the gas tank? Better out than in for sure. Carbs looking good man, seat cleaned up really nice too. And the redneck ultrasonic - is that a palm sander strapped to a coffee can? Marvellous.

No worries mate. It's safely stored and not going anywhere. If you decide to go that way we can just wait until the borders open up again and save $$ on shipping. :)
 
If only used in the dirt, I'd probably put new tubes and rim strips in the old tires. If used on the highway at all, new rubber would be a must.

Yep and there is a little glass pyrex wit a rubber lid with the brass. It really works. The tank is still solid but there is at least the same amount of rust to get put. Put a chain in it and been shaking it evey so often.

Yep, I looked again at them. They are hard as rocks so we will change them out.
 
My RD400c has rock hard tires old enough to have voted for Reagan. Thinking about Shinko 712s for it.
 
Those or Avon roadriders. Budget and availabilty will determine which. Ive ridden on both and like em both
 
I'm about to change into my 4th rear 712 on the airhead over about 14k miles. 4600 miles on average on a budget rear tire aint to bad, especially considering how much of my commute is chip n seal roads. I always think I'm going to try something that might wear better, then I look at my account and decide to go with a 712 again haha. The Avon roadrider on the front has held up through all 4 rears, BUT that's not surprising given the lack of braking power lol (and the usual front wear vs. rear)
 
I've only put 1000kms on the Roadriders on my CB but so far so great. Can't see me switching them out for a different brand or model when it is time to change them. Lots of confidence in the corners and no problem on slick roads. Even tar snakes (which definitely get the heart racing on the Shinko 705's on my KLR) are no drama on the Roadriders
 
I had 712s on the cx and they were great. Have 230s on the gl and those are too. Had roadriders on the 450T and also great. Put 12K miles on those and still had half tread when I sold it.
 
So we dumped vinigar #2 and the same amount of shit came out. Good news is I can now see clean metal in places so making progress. Cleaned some more and through a 6v battery on and head and tail lights work. No signal flasher so need one of those. Missing main fuse so will grab that too. Nice thing. Brand new points.

So, the front brake on these is crap. I am really thinking it needs to be upgraded to hydraulic. I can't find any good info on what others have done except a full fork swap. I am thinking of buying a caliper and master cylinder from an newer bike of similar weight and performance and making a bracket to mount it. Anyone got any suggestions? I'm thinking a new CB125 setup, or even a Scooter setup. There is a used SR50 caliper and master on the Scooter site with new pads for $75. SR50's have good stopping power for scooters and should weigh pretty close to the same, got to check for sure.
 
Anything you do is better than the mechanical disk. I have seen some with fork swaps but most of them seemed out of proportion to the rest of the bike.
