Questions & Answers


Does the intake boot come with the reeds for a 1993 YZ80?

By Anon.

Is everything in the picture included? Does it come with The reeds an the intake part pictured as well?

In the case of the 1993 YZ80 V-Force reed valve, yes, the intake boot is included. The kit comes with everything you see photographed, plus a gasket and screws. Everything you need is in one box.
