Owned my Fz1n for 12 months, fueling glitch i cured that with an Ivans fuel sensor, it puts fuel into the bores when you come off the throttle, so when you open the throttle there is no sudden kick to upset the bike mid corner. I paid £150 for this item and is realy easy to fit. I put a one tooth bigger sprocket on the back about £30. the standard tyres were replaced by Pirelli dragon corsas, then a pair of Bridgestone 015, I put a 180 on the back to quicken the steering, this has made the handling much better, R & G crash bungs were fitted about £50, about a week after i got the bike i pulled up at a junction and when i set off i got the top of my boot caught on the right hero blob, so they were taken off. A tail tidy was fitted, a Piug screen was fitted which gives a lot of wind protection and looks brilliant. Then i fitted a moto GP style Micron, K & N air filter and Dynojet Power Commender, the power commander was set up at Jordans bikes of Leeds, it now has 147 bhp at the back wheel and max torque = 71.55. the fueling is also much better. to make it more comfortable i fitted a sargent seat. The only thing i need now is a Hagon or Nitron rear shocker because the standard shocker isn`t very good with an uneven road surface but is very stable on a smooth road. apart from the shocker i think this is an absolute stonker of a bike like everybody sez it does everything. after owning 8 sports bikes this is a very comfy fast bike, I love it. And i wont be buying another sports bike this one is too much fun.
