Hello All. Looking for some other possibilities which may be the root of my problem. My ride is a '99 Iron 500ks, stock except for TM32, Ace Air Can and shorty exhaust.
Problem: This just started. I feel a bad vibration, mostly on deceleration...coming off throttle when shifting between gears, or just slowing down while in gear. Do NOT feel the vibe when excelerating or steady throttle at speed. Do NOT feel it when reving in neutral. The vibe is definately down low, coming up from the footpegs.
Since I can't feel it when reving in neutral, I'm imagining it's coming from the gearbox?
Here's what I've done so far: Tightened all bolts around the gearbox. One was finger loose, others were tight. Checked gearbox oil....good. Checked all enging mounts, head steady and all bolts on frame and wheels...all good. Opened the Primary Case, tightened the primary chain to about 1/4" deflection in either direction. (It was very loose). Removed clutch pack, but not hub, and cleaned all friction plates and spacers while in there with brake clean. Clutch pack looks good. Checked the 20mm bolt that holds hub...it was tight. Adjusted clutch. Filled Primary with Type F, fired her up, still had vibration...actually, seemed a bit worse. It feels so bad, I'm worried to ride it.
Could something be coming apart in the gearbox? Other suggestions to look for?? I've had a RS Shift Kit on order from our hosts since Feb. Was recently notified it should be in within 2 weeks, so I didn't want to open the gearbox to check things out, since I'll be doing this when kit arrives.
The only remaining thing I can see or think that needs tended to is the main drive chain seems loose. Could this cause that sort of vibration....only on decel? Regardless, i'll be tightening that up tonight and give it another go.
Any advice would be much appreciated!
