Ivanised

[Falcon 269]

Check the carb needles, originals have no provision to change the needle height, hasn't got multiple slots for the 'E' clip.

Unfortunately that doesn't apply to UK/Euro Fazers, only to the US models which have a single e-clip groove mandated by federal law.

However, you can check the needle as Karlo suggested and if you find SD-129 or SD-130 stamped around the top of the needle, it's an original Yamaha part.

Ivan's needles have 5 e-clip grooves.  For 2004 model with 3mm nylon needle spacers, the e-clip should be on the 2nd groove from the top.  Ivan's needles also have a couple of visible variations in the taper, notably toward the last 15mm of the needle.

Another clue will be that the throttle slide spring will have been shortened.  You'll find in that case that one of the ends is bent over slightly whereas the uncut end will be finished in a complete circle.
