I recently got a 1994 750 from my grandfather. It was running pretty rough and had a leak in the carb. Also coolant started spilling out of a metal hose on the left side. I assumed it was just the O-Ring. Anyway, I purchased a good used carb got the old one off after 3 hours and sawing off the air box(i plan on using the cone air filters anyway). I got the metal cooling hoses off and as I suspected the o-ring is toast so I’ll be picking up a replacement for that as well. I also took the water pump off to replace that while I’m here. My question is considering this is a really old bike that was not maintained well, is there anything else i should replace while I have all this stuff off? Any common problems I can address and fix before I put it all back together and have it break again next week. Thanks for any advice.
