Front sprocket change

[PieEater]

I had considered changing the ratios when I have to relace my C&S in the not too distant future but after looking at the costs of a speedo healer and taking into consideration the decrease in fuel economy I've discounted the idea. My Ivanised Fazer is quick enough and if I need to accelerate quicker dropping a couple of gears isn't that much of an effort.

You say you're changing your front sprocket but dont mention the chain or rear sprocket, general concensus is it's better to replace the whole lot at the same time.
