Pricey aren't they. If it's the Gen 1 1000, the T Max 500 uses the same and I just replaced mine after buying a tragic pair of T Max carbs of eBay for 25 quid and it's on and working perfectly. There's a pair on there right nowhttp://www.ebay.co.uk/itm/Yamaha-T-Max-2001-Carburettors-/111416327810?pt=UK_Motorcycle_Parts_13&hash=item19f0ee3e82
