Suzuki Speedometer Gearbox Plug

Installed a TrailTech Vapor onto my Suzuki DRZ-400S (technically it's a Kawasaki KLX-400SR, but same difference), and needed a way to plug the open hole in the speedo drive gearbox on the front axle. The kit for the TrailTech supposedly came with one, but either I lost it or never received one. Anyways, whipped up this plug to keep the gunk out of the gearbox. Use the o-ring off of your speedo drive cable on this plug to get a good seal.
