I recently visited my oh so helpfull Honda dealer and asked if I could buy carb kits for my 400. He practically laughed in my face and offered to sell me
A needle and seat for $30!!!!!!!
I then went on the internet and found a great company which supplies full kits for many bikes (mine cost $17.50 each) The kits include: 1 float bowl gasget, 1 needle valve, 1 needle jet, 1 e-clip, 1 air spring, 1 main jet, 1 slow jet, 1 o-ring, 1 idle screw and one top cover gasget. the kits are made by keyster and can be bought from
