i searched, didn't find much. Ok my question is, how hard is it the get the xr650 motor into the warrior? if anyone has dont it i need information, my dad is a professional welder and since he is absolutely obsessed with the warrior (i dont know why) all the ergonomics and all, hes just that warrior guy, he just wants a big engine, anyone know any engines that go into the warrior without completely tearing it apart? the xr650 motor would be sweet! alright lemmi know anything you guys got, thanks

 

anyone that can weld and fab some frame brackets should be able to do it with very little prob. warrior frame is kinda small might be a tight fit. xr650 uses its frame as an oil tank so you would have to come up with an external oil tank.maybe from a 400ex. good luck

 

warriors frame design is kinda poopy to begin with but, if you can weld then it wont be a problem to get any engine you want to fit, i think ive seen an xr650 engine in a warrior that was used for dunes and the one i liked a whole lot was an xr650 engine in a 400ex and it ended up winning some race serious forget what it was, the warrior engine is actually pretty big so i think you should have the space, me and my dad almost put a wr430 2 stroke engine in my warrior.
