One point for reference, if you have poly riser bushings you will feel vibrations more than with rubber.

 

Well I be. You are one of only a few (that I know of) that have noticed the rivets being loose. Am told not a real common thing but it does happen. Throws the primary drive outta whack. Least it sure did on mine and replacing it made a world of difference. My Evo still has a vib about 1600 -1800 but nothing like it was. What is left I write off to being what it is

You know I'm thinking the clutch might be it but I don't know if I can put myself through another disassembly. It does rock and wobble but I was given feedback that it's normal to move like that. I did disassemble and inspect the plates and thickness all checks out fine.

It feels like stumble or misfire. So if your driving at 3000 rpms in 3rd or 4th, just so it doesn't slow too fast, let off the throttle. As it's decelerating it's smooth and slowing. Then as it hits around 2000 it shakes like hell then stops and smooth from 1900 down to 1000 rpms. I don't know anymore. Runs and handles great otherwise!

"Then as it hits around 2000 it shakes like hell then stops and smooth from 1900 down to 1000 rpms. I don't know anymore. Runs and handles great otherwise!"

That is a very very good description of exactly how my 97 EG does. Short of RPM being a little different. My problem was that I had the chance to compare 4 different 97 and 98 FLH,s to my bike. The vibration at 1600- 2300 would shake the bars and fairing so bad ya couldn't focus on the gauges. The other bikes I compared it to had a vibration that shook things a little between 1800-2000 rpm but never as bad or as big of an RPM range as mine.

I don't think you can ck the rivets with the friction discs and plates installed in the clutch basket. When I washed the oil out of the basket. gear and rivets It really showed how loose the rivets were. I put the gear in a vice and set up a dial indicator. Could twist the basket part to show .040 movement. I knew even if that wasn't the problem it wasn't right. Tom at AMS in Ft Worth said that was the vib and it needed to be replaced. I did so and I am HAPPY Best of Luck WP

 

I think you might be right then. I was leaning away from clutch before pulling the clutch in or out didn't make a difference but I guess the basket is spinning the entire time. Are you talking about the rivets on the outer edge of the basket? Did you happen to take any pics while it was apart?

 

Let me get the basket out, it's still in a box in the shop. I'll try to put things into words. Nope no Pics My frustration level was thru the roof at the time and pics were the last thing on my mind BG I bet ya know what I mean. LOL

back in a few WP

The rivets on the outer edge hold the starter ring in place. Those can be replaced with bolts I have been told.The rivets I'm speaking of will require taking the clutch basket assembly of the bike. Look at the sprocket that the primary chain goes around. There are 6 rivets that hold it in place. These were the culprits on mine causing the vib. Now we had completely took the clutch basket apart and pressed the bearing out. It was going to replaced even though it felt ok. since we were already there. I called and the bearing would have to be ordered. So I ordered it. I was cleaning up in the shop and went to move the clutch basket and when I did I felt some slack. Just a little but felt it. That got me looking closer at things and found the rivets loose. I'm not sure if I would have found this without the clutch Basket being completely disassembled. I'm no expert on these bikes but have learned a good about them with to much trail and error. I'm an auto mechanic by trade. Never learned to type very good, if ya want a BS phone session pm me a phone # or I'll pm ya mine WP David

 

Hmmm... looks at the video KP, Something defiantly looks weird, but hard to see it the way the waves started! I just started mine and did the exact same thing you did..it does have a vibration that comes and goes,and sometimes worse at different rpm's. But it's not really a "shake"

 

. When does yours vibrate the hardest if you sit still and slowly increase rpms or let it drop to idle from a high rpm?

 

At 1800-2000rpm's, you feel it more. But I watched that video again,It looks like it literally starts shaking, not a vibration..??

 

Shakes like hell! From front to back. The back fender moves about a half inch. Oddly I put the apes back on and the bars only shake at idle now. At 2k the vibe is absorbed, I do have 5" lead plugs in the end. I strongly vibes the rest of the bike like hell though. When it's doing this if you're looking at it the engine doesn't look like it's moving at all. At idle you can see the engine moving. It's annoying as hell I know something wrong just haven't found it yet
