Couple of questions to those who've already done these.
I've got a 2003 FZS600 'foxeye'. Great bike, had it since new, 34K so far and definitely a keeper forever.
The K&N air filter. Does it really make a lot of difference ? Do you need to rejet too ? Does it slot in without any mods ?
The Hagon variable compression fork springs. Do they make a lot of difference ? I've had the Hagon rear unit in for 10K now, and I think it is great, and super value for money. Made a world of difference to the saggy knackered standard unit. Front forks have had the 15w oil installed, and they feel fine, but just wondered if Hagon's variable springs are much better. A cheap upgrade or not worth doing ?
