I saw where there is an additional bracket for scooters, hope that is the case. I would LOVE to order 4 valve head, but no case splitting yet until necessary, plus have to add longer timing chain , I believe. My birthday is coming up and my wife said her sister might by the valve head for me
We will see. Until then just saving the money to get a quality one. either that or buy OEM and have it P&P. Leaning more towards the 58.5 valve head.
