The ones i found are china roller rockers that are ment to be made to yx specs the have yx stamped on them it say they go stright in stock head and ti ritainers for 60 bucks for both i have to have to have a look
I found one lot from akauna but he dont have a cam to suit then when I asked around I heard they dont fit and to make them work is more trouble then is worth even if u find a cam.
Then I found sum at a shop in hong kong twowheeldeals that say they are made by yx factory for the stock head but I cant get in contact with them to find out anything.
So I got a tbv2 head with the new forged alum roller rockers and new stainless intake and exzorst valves
I still wana try talk to this twowheeldeals and see wat they say about theres
The tb v2 now has new forged alum roller rockers for the same price so u dont have to pay $$$ for taki ones
And it now comes with two stainless valves instead of just one
