I have a Vulcan 750 2002. It picked up a bad vibration within the last two weeks so much my right foot gets really numb. SHe also wasnt running right, hesitating, low on pickup at times, so even after sea foam I decided to pull the carbs and clean them. They were gunked up a bit and after a bit of learning experience they are on the bike again and it runs great... But the vibration is still there. I bumped one of the coolant hoses into the rear cylinder so I had to drain some coolant and replace the O ring. I noticed in the coolant metal filings or shavings. Looking on the diagram the water pump is directly beside the right footpeg. I am wondering if anyone thinks or had this problem that the impellar is causing the vibration. Has anyone changed this? How much time is involved. It doesnt look that bad to do. One more thing, I read somewhere on this forum that if the oil is overfull that that could cause vibration. When I bought it used from the dealer earlier this year I noticed that the oil is wayyyy full. I asked the dealer and he said it was fine and they fill all their bikes that full. I dont believe them. All info I read says fill between L and H when on centerstand. That is why I may take her to a private shop if I can find one. Actually if I can do it myself, I would. Its hard to find good reputable mechanics especially the dealers. Sorry to ramble but the oil is free of debris. I dont think it is the dampeners. Any thoughts. BTW engine mounts seem tight.
