I have a Fly wheel puller that I had bought from RMATVMC when I had my 2010 YZ450. I was wondering if it would fit on my new 2015 YZ250 (2-stroke). If not is there a compromise? I have a GYTR 8.4oz Fly wheel I'm wanting to put on tomorrow evening so I can try it out Sunday at the track. I know that proper tools are needed to be used for the job but sometimes there is tricks or other ways to do certain things. Like for example: using a threaded rod with some nuts and washers on it to make a tool to press swing arm bearings out where other wise you would have to buy a tool from motion pro for $80. Just wondering if there was another way to get the stock fly wheel off and the GYTR on with out having to use a puller if the one I have wont work. I seen where some people say to use a Air impact gun. I can see using that to get the outer nut off but how to pull the Fly wheel off?
