I have noticed that when I go into a turn hard I am feeling a clunk through the pegs when going over bumps. I don't feel this clunking when in a straight line over bumps. The bike does not seem to be doing anything strange in the turns but I am still working at scrubbing the Michelin man off the edge of my tires. Although I am a little fatter than would be ideal, I am not bottoming out my rear shock. My rear isolators don't look toasted and the shock bushings seem to be intact. I have a reworked OEM shock from a fellow Bad webber that changed to a Penske unit and have only ever bottomed the shock riding two up. Any suggestions would be appreciated. | ||

I would be looking at all motor mounts, swing arm mounts, isolators unless under 3 years of age would be replaced. that thump is some thing moving. plain and simple also wheel bearing? isos can look ok and be bad. one last thought peg mount bolt? | ||

They all sound like good suggestions. The puzzler is that this clunk does not occur when going over bumps in a straight line. I took the Road King to work as my Commute is 90 miles a day and the interstate seems like a bad place to discover the cause of my problem. I'll look again when I get home tonight. Thanks | ||

check that your battery isn't loose , I had something similar, was the battery bouncing up and down. | ||

Isolator! Swingarm bushings. Thats my bet! | ||

Swingarm bushings ?? the arm is supported by timken roller bearings that turn on plugs on the 99& later tubers a thin bolt tensions the bearings. the isos are outboard of that. battery is also a great suggestion the thump is felt while turning? } | ||

Mine is a 98 S1. The clunk is only noticeable while turning and generally only hard turns. An issue with the swingarm bearings would make sense considering the twisting forces applied to the swingarm when turning. The bike is relatively low miles though, 18K | ||

I HAVE THE SAME TROUBLE WITH MY 1999 S3, MY ISOLATORS LOOK PERFECT AS DO ALL MOTOR MOUNTS. I MOSTLY NOTICED IT IN HARD RIGHT HAND TURNS BUT IT SEEMS IT'S DOING IT BOTH WAYS NOW. | ||

I'm with old dog on this one. Look on the inside of the frame near the front head. This is where mine was hitting. Joe | ||

NN: the newer ( me saying this my bike is 7 years old ) bikes have big steel plugs that hold the roller bearings the races fit in the arm the plugs are allowed to float in the rear engine mount a small bolt pulls the plugs together and this pulls the bearings tward each other there is a pinch bolt in the mount on each side once tensioned you tighten the pinch bolts check the service manual for the S1 for differences between the X1 and the S1 but they are not all that different. you have 3 rubber mounting points. and 3 or 4 tie bars My "bearing mounting plug" needs to be replaced as the plating is worn off and the thing is now too small. most folks never disassemble and grease these parts and assume that they are OK. Until something like this happens, mine are on a 2 year rotation, this year the front end comes off and the bearings get cleaned and re-greased ( replaced if needed ) I dont go by the odo, all preventive maint is done on anual rotations 1,2,3 years | ||

Jim. Thanks for the info. More things i didn't know for sure. I think I'll make mine a winter project and just replace all iso's and bearings. | ||
| Eshardball |
thanks guys. I'll start in back and work towards the front mount. | ||

I checked the bike again after a not so aggressive ride through some twisties. Fount the right isolator showing a tear on the bottom. Right now its a clunk. My question would be is it unsafe to ride like this or just annoying? Thanks to all that offered their input. I guess I might as well dive into the swing arm bearing since I will be half way there when I do the isolators. | ||

I dont know about the bearing on these but most likely it might be a waste of time. I would get advice from someone here who has alot of miles on their bike for that. For sure fix the isolator ASAP. | ||

After closer inspection it appears that the iso is failing ... so the bearings may not need attention. the milage of my bike not with standing  | ||

My clunk felt through the pegs while in hard cornering turned out to be shot bearings on the main shaft in my transmission. Hope that's not the case with you. | ||

Mine is definitely rear isolators. I had the bearing on mainshaft 5th start to walk a year ago but I was able to drive it back in and stake it so it wouldn't drift again. It has not been a problem since. If your trans bearings are smoked, check to see if your rear belt is too tight. |
