I'll be going the APE 485 + support mods after doing my own research.
Thanks John it looks like I have another cam option to consider, is the cam a bolt in only or do you need to upgrade valve springs? I can't find much info on it apart from this vid which sounds pretty mean- https://www.youtube.com/watch?v=o8kRnLofKz4
after chatting with Fuel Moto USA(good to deal with) I have settled on the bolt in Woods WM8-22XE cam and the instillation kit- lifters, adjustable pushrods, cam bearing, 55mm inlet manifold and 5.5gr injectors and black pushrod covers with black lifter blocks - https://www.fuelmotousa.com/i-23898865-wood-performance-wm8-22xe-chain-drive-camshaft-with-pushrods-lifters-kit.html
23 hours, are they taking the piss? Or does that include the time the bike will be spent there overnight haha.
