A buddy picked up a 99 Vulcan 1500 for cheap. It had been disassembled by the previous owner due to the oil gear failure. He only pulled the side cover and clutch pack and saw what was wrong and stopped there. We bought the JOG and installed it without any issues. Played with the puzzle for a little bit trying to figure out where all of the bolts and such went, but once getting it all back together the clutch won't fully disengage. At first it would kill the engine when you put it in gear, but it has loosened up to the point that it will now idle, but it's under a load and it's very difficult to put it in neutral without shutting it off. We haven't ridden it but about 10 miles in all, so I'm thinking maybe the clutch disks are just somewhat dry, but it could be something missing. We did end up with a large coil spring left over, but it could be from something else too. It's about 4 inches long and about 1-1/2" diameter and I can't find anywhere it might go. The clutch does disengage quickly as you pull the lever, and there is plenty of travel once it releases so I don't think it is air in the lines. It's more like the disks are just dragging. Any idea's what might be the problem, and where this extra spring might be from?
