I have acquired a '07 Suzuki DRZ-400s. Unfortunately, the bike has sat at least for a few years and obviously wont turn over. When I asked my neighbor details she thinks her son didn't start it for a while before he went to prison (shitty for that dude). I am decent mechanic and have rebuild Subaru engines and have decent knowledge of the internal combustion engines. What have I done so far: -Rebuild/Cleaned carb - Drained oil- and this is where things got interesting! The oil went bad. It started to pour out looking like water then followed by dark black/brown sludge. -New battery -Concerned with internals I turned over by hand first and it was really rough and barley turned (even with new oil) With spark plug out it shot out more separated oil. Where should I go from here......?
