Kamanya and DirtADV thanks for the help and pics
I will read through your rebuild thread.
I am torn now with splitting the case after your advise and what has been posted previously. Bike shifts fine and never a false neutral.......but who knows. Part of me would love to yank the heads, new rings clean up the valves and be done in a weekend. But then I would hate for a problem to pop up 2k later that I could have addressed the first time.
One question I have that has not been clear after reading different rebuild threads is how to remove and then replace the main bearings? Do I need the special KTM tool to get the split bearing in and out or is there a shade tree method? I have a shop press, just trying to figure out if the KTM tool is necessary?
