Suspension

Hmm,

It's all a bit more than I want to spend. This is my everyday bike for throwing around town.

From reading that, I'm unsure of the breakdown of costs.

I am very handy with spanners. I've stripped and built a few bikes and cars.

How much for:
Springs and Oil?
Rear Shock?

Is there any point doing the front and not the rear. Although I almost feel that the rear is the biggest problem as it bounces all over the place.

Here are your options, all from memory from when I looked into it a while back, so prices may not be up to date.

Front:
Springs and oil £70
Racetech Internals £200
Matris fork internals £280
GSX-R front end swap - Cost hugely variable based on whether you keep original parts or sell them, how cheaply you pick up the gixxer bits/the condition they are in, etc.*

Rear:
GSX-R/ZX6-R/Similar shock - £10-100 based on how urgently you want it, condition, etc.*
New "budget" Hagon shock - £230ish
2nd hand Ohlins/similar off ebay (often false economy once a service is factored in)- around £250
Ohlins/Nitron/whatever - £350-450

I'd choose from the above based on your budget, giving priority to the bit that causes you most grief (sounds like rear shock).

*Whilst all might have insurance implications, these are more likely to result in insurers hiking your premium/refusing to insure you, so you might want to get quotes to see what the "total cost" of these mods are when working out how much it costs.

Other things to add on.

Gixxer swap highly depends on the gixxer parts being about right for your weight to start with.

Shocks. Robw70 can build a custom version of a GSXR shock for less than ohlins equivalent
