Questions & Answers

Ask Question

Will this work for my 60th anniversary y450f?

The 60th anniversary YZ450F uses the same cylinder head and other engine components as the standard YZ450F for the same model year. There's no difference in the engine between the two bikes, so choose the YZ450F for your year from our fit guide and you'll be all set.

Answer Question

It says white diamond or black diamond stainless steel valves but don't let you select which one how do you know which one you will receive

Once you select your exact make, model, and year from our fit guide, you'll see the exact valve type that's included with the kit that would fit your machine below the main description under "valve type." In the instance both types are available for your ride, you'll be presented with the ability to choose between the two.

Answer Question

Does this work for a 2013 kx250f

Yes, there is a kit available for that 2013 KX250F. Just be sure to choose that model before adding to your cart.

Answer Question

Yes! If you were to select the 2005 Suzuki LT-Z400 QuadSport 400 cylinder head service kit from our fit guide, you'd receive all of the correct components to fit that ATV.
