Triumph Thunderbird 900 and Legend Mikuni Carburettor Rebuild Kits (Set of 3)   (Stock Reference J080)

Basic Mikuni Carburettor Rebuild Kits, with Viton Float Bowl Seals x 3, Viton 'O' Rings x 15. Also includes 6 x Float Bowl Screws, idle cable bracket screw and fitting instructions (Set of 3 kits).  

Where Mikuni carburettors are used, these will fit Daytona 750/900, Speed Triple 750/900, Trophy 900, Tiger 900, Trident 750/900, Thunderbird 900, Legend, Adventurer, Thunderbird Sport, Sprint 900, Sprint Sport and Sprint Executive.

The kits also include the slide block base O-ring, which often gets left untouched. We know it says in all the manuals never do it, but in the real World a piece of fuse wire can be pushed through the pilot jet and pilot air screw hole, compressed air often doesn't clear them if blocked. It's common for the two float O-rings to harden and cause over fuelling problems. When refitting the float assembly into the carburettor body with the new o rings, use a little lubrication on the new O-rings such as WD40

While ethanol mixed with petrol is known to lower engine emissions, these blended fuels  increased permeation through plastic and rubber. Viton has excellent chemical resistance and helps resist these problems, but unfortunately carburettor rebuilds in the future may well be more frequent as the percentage of ethanol increases in pump fuels. If the bike is not to be used for a long period, it's a good idea to drain the fuel from the fuel tank and carburettors.
