I"m in process of restoring my 93 vmax-4. My plan was to do the suspension this year(Have sent every thing off to Schmidt Brother), and ALSO DO all maintance. Then next year have it painted.... I just turned 2000 miles and sled runs great. When I was changing my gear oil I noticed a small crack at the bottom where the drain plug screws into the bottom crank case. The crack is very small and just at the bottom of the threads(about 1/4 inch max long). Does anyone know what my option are? I pulled the motor yesterday and was planning on bringing it to a guy the specializes in welding aluminum. I'm praying I don't need a new crank case. Has anyone heard of this problem. Any suggestions-----PLEASE HELP!
