I currently just purchased a 98 warrior knowing it needed work! So far I have found the timing off couple,rtv on casing,and a stuck rocker arm. I can fix the timing does any know how to fix the stuck rocker arm or should I just get a new head? I’ve heard of putting it in the oven, cutting the rocker arm off,currently I have have been just working it with Kroil and soft jawed pliers to try and loosen it up. Just want to find the best option to get my bike back on the road! Thanks
