Reconditioning shocks?

[Valver]

My FZR750 has been bouncing about the road for too long and with winter looming i can't really risk running the bike much longer with the rear shock the way it is. I bought a replacement on ebay last week (very cheap) but it doesn't seem much better.

Where can i send one to be overhauled? Can i do it myself with a kit? Is it expensive? Should i just bit the bullit and buy a new one?

Hi

There are quite a few places around. Such as Revs Racing in Halesowen.

Think a rebuild will be £60~£100 depending on what needs doing (eg, is the damper rod OK).

All the best

Hi

When springs go they tend to get a bit soft at the initial part of their travel (not really a common problem). When damping goes it just allows the spring to bounce around.

All the best

Hi

Trouble is bikes tend to be a lot more sensitive to damping, and some people will have massive problems with the handling long before the shock has blown all its oil out.

Had a few odd problems with shocks. My FZ750 one was working OK but the damping was slightly weak on it so I adjusted it slightly. About 1 mile later I had no damping at all. Its replacement had a horribly sensitive damping adjuster and went from taking 5 seconds to rebound to almost taking my nose off on the rebound with a tiny turn of the adjuster. Old Aprilia AF1 Futura had damping when I went onto a roundabout and resembled Zebedee when I came off the roundabout.

When she shock on the Divvy went I had it rebuilt but it turned out the body was too work. The seals on the piston came out and pretty much jammed the shock.

Can be quite worrying watching car wheels sometimes. It is not that rare to spot a car with a dodgy shock and the wheel bouncing all over the place.

All the best

The spring has corroded and cracked in places. Its lost about 30mm of seat height in the last few months. The damper makes a crunching sound when you push it hard
The new one i bought ain't much better but atleast the spring is in better condition.

Hi

Suspect the spring can easily be replaced. Maybe with a nice tarty yellow Ohlins one .

At least you have a spare one to get rebuilt so the bike is not off the road while it is away.

All the best
