Ok - I started with a 1990 ZX10. Done roughly 100,000km, but the engine was\nstill good. Would have been worth ,000 tops if I had sold it.\n\nFrom standard I have:\nFitted Magnum cans - 0.00 - Very nice sound. Bit more\nperformance, but mostly just the noise. Worth every penny.\nFitted V&H Ignition Advancer - - Helped remove flat spot, and\nhelped idling. Worth it.\nFitted K&N Filter - - (I got 2 but I can't remember if the \nwas each or for the pair.) Not much noticable difference, but lasts a lot\nlonger than the normal filters. Worth it, but only really on a monetary\nvalue thing. Made the induction noise a bit nicer too, so that was good.\nLowered forks by roughly 15mm. - </body> - This sharpened up the steering\nmore than I thought it would. Very definately worth it.\nBraided Brake Lines - $Can't Remember - Worth every penny. MUCH\nbetter stopping power.\nPut in heavier weight (I think) fork oil - </body> - It was due for a\nchange anyway. This has also helped out heaps. It doesn't dive anywhere near\nas much now. It handles much better on a smooth road, and gives much more\nfeedback (this is both good and bad) on a bumpy road.\nRejetting - 0 - This was the one I was most skeptical about, but\nI am very happy with it.\n\nSo, the grand total: 60. I think I would be hard pushed to find a better\nbike for 60 with as much life left in it. (Cue people sending me links,\ntrying to sell me their bike etc etc), and even if I could, I doubt VERY\nmuch that I would find one that would put a bigger grin on my face. And\nthat, afterall, is what it's all about.\n\nI may not be that fast, and may not handle that well, but it feels fast,\nsounds nice, and keeps me with a big grin on my face.\n\nStill wish I could afford to put a turbo on it though.
