I wanted to do the same mods years ago on my FZR-Exup and tried Progressive Suspension multi-rate springs,but there was no settings that I could adjust that made the front handle in the way that I wanted it to do.I had read that straight rate springs were better,so I bought some Ohlins springs from Harris Performance and what a revelation.Much easier to adjust for what I wanted the forks to do, but not quite 100%.As the forks on the Exup are only adjustable for preload I read that some cartridge fork emulators were available from the States so I ordered from them well before PDQ in the UK started being stockists.
But with your bike having a fully adjustable front end,the best recommendation would be to fully service the cartridge and clean everything and check the service limit of the springs.A decent quality fork oil may well be sufficient after replacing any worn bushes.
I looked on the Ohlins,K-Tech and Race-Tech websites but not one recommends a suitable spring.I would suppose that many think that the OEM spring is good enough if within limits.

As for the rear shock,which from what I have read is not rebuildable,the YSS item from Wemoto is reasonably priced and on a special atm.

What age are the tyres that are fitted?A friend has just fitted Michelin Road 5s to his 1000cc bike and he was surprised how good they have turned out to be

If the front tyre is of that age then I would seriously consider changing it,whatever the remaining depth of the tread pattern.
I fitted Michelin Pilot Road 3s to my FZR-Exup which have the same wheels as on your ThunderAce.These are 3.5" and 5.5" which will accomodate a 120/70 and a 180/55 on the rear.A larger 190/50 is not worth attempting as it will not fit the 5.5" rim correctly and will affect the handling.A friend tried it on his Ace and he very quickly regretted it after one ride and replaced it with the recommended 180/55 size.
As both the Pilot Road 3s and the 4s have now been superseded by the Road 5s,you might get lucky and find a stockist with them at a good price,or try https://www.oponeo.co.uk/moto-tyre-finder to get an understanding about what is available at a reasonable price.
Demon Tweeks also sell good pair deals https://www.demon-tweeks.com/uk/motorcycle/wheels-tyres/tyres/ ____________________ Just talk bikes.What else is there?

For anything with damper rod forks - old or new - I'm a fan of cartridge emulators. They make the damping better than new, which is useful when the roads are in worse condition than 20 years ago. I wouldn't replace the springs unless the current ones feel wrong. It's very easy to make the suspension feel different with new springs, but much harder to make it better.
So front suspension is fairly cheap and easy to improve. YSS cartridge emulators are about £60 from wemoto, a tenner for new oil, and an afternoon to modify the old damper rods with a drill and fit it all up. If you also go for new springs that about £100 more.
Rear suspension is more of a pain, because the only real option is to throw money at it. You may get lucky and find that either the existing shock can be rebuilt, or the standard shock from a newer bike is a direct replacement and upgrade, but more likely you're face with buying a new shock. Lots of options, lots of opinions, but broadly speaking you get what you pay for and it isn't worth spending less than £300.
Of course, you don't have to do both at the same time. If you do one end you will probably want to do the other end pretty soon, the bike will feel unbalanced with decent suspension at one end.
New tyres too. Ancient tyres are dangerous. They feel fine, they work fine until they don't - and let go suddenly. |

That is debatable. |
Most things are, but I think so. Excellent tyres for coping with whatever is thrown at them I find. The PR2s were the first tyres I found I could nearly keep to the same pace in the wet as in the dry, after years of riding bikes, and the 4s are as good, if not better. Doesn't mean there aren't other tyres that are good too. ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

When you find a tyre that works for you, it is hard to bring yourself to move onto something else. Why would you, with the risk of spending all that money to find you didn't like what you'd changed to? Of course, if money is no object, no reason not to experiment with other brands/models. ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

I won my first pair of PRs, gratis Was much impressed, so stuck with them.
Out of interest, what is the typical life of a standard set of fork springs, if there is such a thing as "typical" in this regard? ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

sounds like one of those how long is a piece of string questions.
i imagine multiple different things will determine the life, such as riding style, weight, road surfaces, temperatures, oil change frequency etc. |
Yeah, you're probably right. I think my attitude has always been, if it's all working fine, leave it alone. ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

Have you bought a Haynes manual for your Ace yet?
