Yeah, they ain't cheap really!http://www.ebay.co.uk/itm/Yamaha-FZS600-Fazer-98-02-Carburettor-To-Head-Rubbers-Carb-Inlet-Rubbers-/130940850602?pt=UK_Motorcycle_Parts_13&hash=item1e7caed1aa
Hi there. Thought I needed some for a while as mine are cracking but was told to idle the bike and spray a bit of WD40 over the carb rubbers and if the revs increased then this indicates that they are split through.Also when I had my bike MOT a month ago I mentioned to the tester about the cracking on the rubbers and he said they can look cracked and splitting on the outside for years before they split through.These are the cheapest I could find; http://www.wemoto.com/bikes/yamaha/fzs_600_fazer/98-99/picture/carburettor_to_engine_inlet_rubbers/
