Have you made one your self ? It can be done. We ones specially got 50 special Headgaskets made for the Yamahas ( 998) The cost was about 75.00 per piece for 50 . Or $700..00 for one piece .
We thought lets do it , we need at least 10 our selfs , everybody will gladly pay $100 and we where wrong . I still have 30 Head gaskets .
You can work it out your self who his crazy . ( I am the crazy one , but I am cured now )
