HiBeen reading a little about flashing the ECU to get rid of the jerky throttle at lower revs, my bike is a Gen2 FZ1, do any of you on the forum have any ideas about this, would it be expensive and I bel;ieve the ECU is under the air box.

I put a new battery on my bike FZ1 every year, and if I don't keep it on the optimiser, it flattens within a week, it is now un rideable really for fear of getting caught out. I think there is a bad earth or a leak to earth, but recently I have seen a lot of stuff with the Alternator/generator falling to bits, does anyone have a clue as to what it might be. Thanks guys

Hi Guys
Was wondering if anyone could throw some light on this, I have a 2007 FZ1 and I just purchased a Leo Vince carbon slip on silencer, I took the standard Yamaha one off, together with the power valve cables (pushed them back under seat) the distributor told me that the short link pipe would simply slide over the existing header pipe without any exhaust packing ring...well it don't, there must be 2mm at least gap, which could never be clamped.

I pressed on anyway, and soon found that whichever way I twisted the can and it's link pipe the can would foul the swing arm, I pulled the link right to it's extreme on the header pipes end, and it still looked very suspiciously close to the swing arm, then I attempted to fit the carbon strap to see if this at least did fit. I found that if I followed the instructions and put all the spacers on as described, the long bolt was not even long enough to pass through into the original rubber mount hole in the rear passenger footrest hanger, and if I did use a longer bolt, I'm thinking that the link pipe joint to original would be strained dramatically.

Have I purchased a fucking bag of shit or can anyone assist with some ideas. Thanks in advance Guys...
