rear shock limits
What causes the rear to kangaroo when driving through corners?
1998 Firestorm, 47,000 miles, forks valved & sprung, proflex shock +4mm over standard, manual ccts', k&n, 50#slow 185#/190# mains, front carb slide mod, R6 throttle tube, Tank raised, Viper cans, Coerce fork brace, EBC lite front discs & pads.
Re: rear shock limits
In my case a fat bugger onboard
Sounds like lack of rebound damping
Screw in the adjustment screw on the bottom of the shock a bit at a time see if improves if not it needs changing or rebuilding
Just a thought check your chain tension in a few spots just to make sure there’s no real tight spots and drive rubbers just in case it’s a bit of rebound in the drive train making it hop

Re: rear shock limits
Also make sure your tyre is good and the pressure is spot on but it does sound a bit shock like. How hard are you riding? The stock rear shock isnt up to much anyway but has it just started doing it, or is it the good warm dry tarmac egging you on?

Re: rear shock limits
Good advice so far IMHO.
Also make sure the rear suspension hasn't seized up, see link:-

If the rear suspension has not seized, (as Warby says) I'd be inclined to think it was probably due to the lack of rebound damping too. How many miles has the standard shock done
To check if the rebound damping is shot or not, if you push down on the seat with the bike upright the rear end should come back up under control, it should not spring back up.
I find the best spring position on a standard Firestorm shock is the softest setting. The softest setting gives you the closest to the required amount of static sag recommended by the experts.

Re: rear shock limits
thanks guys for the replies, was thinking the rear shock was nearing the end of its life and probably only come about as the weather has been so nice, the V2 stomp even more addictive, so i am riding a little faster/giving a bit more throttle through the bends certainly makes riding more interesting!
