I'm putting together my first Thumper order and thought I would ask you all what I needed, and I mean NEEDED. I recently purchased a couple of good used bikes, '03 WR250 and an '02 XR200R. I want to do oil and chain maintenance and have no specialty tools. I plan on getting a chain puller, thumper 20-50 oil and oil filters for both. Can you think of anything else like gaskets or washers etc.? Thank you in advance!
