So most here are vaguely familiar with the DS isolator... http://www.dragspecialties.com/fatbook/6/294/77257 84 Has anyone tried these from the same Parts Unlimited/Drag Specialties catalog? http://www.dragspecialties.com/fatbook/6/294/77257 85 Isolator mount "limiter". Says for Buells, looks like a compact spin off the stenzel bar, but how do you secure it to the chassis? http://www.dragspecialties.com/fatbook/6/294/77257 68 Heavy Duty Front Isolator... beefier mounting bracket, nothing descript on the quality of the rubber inside... One if not both said you could apply to Buell/tubers in the paper catalog. | |||

BUELLers: Anybody ever question the "PRICE" deference between BMC/Harley-Davidson parts, BMC parts, and Drag Specialties parts which have on BWBers been established to be the same part/parts ??? | |||

I prefer Buell iso,soft rubber nice ride on S2T.Too bad is there some-way to impregnate rubber with Kevler fiber?  | |||

I bloody well do not believe this, PLEASE limit the posts to data to the List that Frank started!!! We are trying to determine the magnitude of the problem. and get a sense of the number of failures take the grumbling else where, please post questions on another thread again Bike milage 1st iso failed at milage iso make 2nd iso failed at milage iso make mods, comments PLEASE!! | |||

Cross posting a bit but its relevant to the data that Frank wants. What I've alrady provided: 1995 S2 70000 miles 1st iso replaced as a set with failed rear iso at 60K, all Buell parts 2nd iso, the Buell part, failed at 1000 miles. And here's the new data: I've realized that I failed to install the washer between the hanger and the iso. Found it in the pile of left-over parts from the rebuild. Currently installing the 79D, with all washers. | |||

For those of you that cannot open the file the information needed is as follows: 1. Year 2. Model 3. Total Miles 4. Riding Style (Easy, moderate, aggressive) 5. # Miles when original isolator failed 6. Type of isolator used to replace original 7. Number of miles between failures 8. Modification done to the bike (ie headwork, HRHS Bracket etc)

1. 1997 2. S1 3. Approx 28K miles 4. Aggressive, former jap bike roadracer 5. Broke bolt whole out of head, bolt intact at around 24K miles. ISO looked fine, I might put it back in. 6. Barry softer version 7. No 2nd failure yet, although it looks like it is starting to crack on the bottom, so may be soon. 8. Forcewinder, KT pipe, stock top end when broken. NOW: welded front head where broken, NRHS bracket, shrink ported heads. (Message edited by skntpig on July 20, 2009) | |||

All, thanks for the info so far. Please keep it coming. If you just want to send it to my email use f_skinner at yahoo dot com with ISOLATOR in the title. When we have a good sample it will be sent on. Thanks | |||

02 M2L first front isolator failure Odometer reads 16,000 miles, happened 5 days ago. Commuter, I've done 2 wheelies, like to hit the corners,70% solo. 6'2" 230lbs. before beer. Have not replaced as I just talked to american sport bike and he told me there ain't anything good right now, but that Buell was working on a fix? this true? | |||
| Oldog |
Frank please post up the sheet when you are "done", thanks.. | |||
| F_skinner |
Oldog, with only 15 entires and only 4 having a problem it is not a large enough sample. As someone that used to do testing for a living this small sample would be thrown out. Ao and Do (Availability and Dependability) are very important. I think I could guess the results. I will give it another week and will wash my hands of it. | |||
| Oldog |
Frank some of the "complainers" should be counted Nastin 3 failures GoingWindward 2 or 3 failures I am sure that there have been others. | |||
| F_skinner |
Right, I will not dig through threads to find the info. If I know Gowindward he is already working a solution for his bike. It is up to the people to give me the info. Here is what is needed again: 1. Year 2. Model 3. Total Miles 4. Riding Style (Easy, moderate, aggressive) 5. # Miles when original isolator failed 6. Type of isolator used to replace original 7. Number of miles between failures 8. Modification done to the bike (ie headwork, HRHS Bracket etc) | |||

Hey...I'm not a complainer!!!! I do not believe mine are valid data points. On the S3T I will admit that I have exceeded design load capacity of the bike, not by much, but still exceeded the design limits. I have also done "experimental" (the brace/strut) fixes. I also know the first owners of the bike EXCEEDED design load limits too. I pity the poor engineer at Buell that gets this turd dropped on his desk because the data points are all over the place, and very little if any control points. On the S2...well it was a 13 year old rubber part....Makes you say Oh Crap! and replace it. Beside trading the bike in for Megan Fox, which I think was a fake offer, I'm fixing it up with aftermarket parts and will be out touring again. I will also be packing just a wee bit lighter.

I pity the poor engineer at Buell that gets this turd dropped on his desk because the data points are all over the place, and very little if any control points. BINGO, and we have a winner!!!! Maybe something will come of it and maybe not. It does not matter to me but I really would like to get my hands on a tuber that is shredding a front isolator every 500 miles. | |||
| Buellistic |
Questions not asked: Do you have a TIE BAR from the front motor mount to the frame ??? Do you have the L0504.9L and L0505.9L rear isolators installed ??? | |||

>>>I pity the poor engineer at Buell that gets this turd dropped on his desk because the data points are all over the place, and very little if any control points. Independent testing of a wide range of options is under way. Any data, relevant or not, as long as it is accompanied by the explanations discussed might be helpful. I think the concern is real. But solid data is a bit sketchy, hence the independent testing. Seems like a solvable sort of thing. | |||
| Buellistic |
The way it used to be: The engineer designed it, was given to the R&D people whom could not break it, and finally to the BUELL rider whom found the flaws !!! Since the BUELL rider does not know anything, there is no problem unless someone is KILLED, which then means the fix is "ASAP" !!! | |||
| Oldog |
Sorry Loren, I did not mean to lump you in with the "complainers" I apologise I should not have refered to any one as a "complainer" the frustration some have vented was understandable, Frank If you think it will make a difference in the results I will dig through the threads and try to list the failures, from the accounts. BTW my bike was not over loaded, nor seriously abused, and two isos failed, I still have them if the Buell guys want them for post mortem. Loren one last thought what safety factor is applied, are you saying that you grossly overloaded your bike? | |||
| Gowindward |
Jim, bike was overload by maybe 25 to 30 lbs. This last trip I weighed everything being packed on the bike, myself and Mb in riding gear, and checked the owners manual just to be sure I wasn't pushing it real bad. Not much safety factor from my view, but it is a performance motorcycle and not a bulldozer. | |||
| Court |
Might make a good campfire story but it's a long way from the way things really work. >>>Olddog: If you want to package them up and send them to me, with as detailed as explanation of their history as you can recall (essentially the stuff in the spreadsheet)I'd be happy to take a look at them.

I've been reading both threads now with interest and starting to get mildly concerned. I replaced my front iso with the one from American Sport Bike simply because I had the motor out and it was easy to get to. The original has 24,450 miles and no visible signs of wear. The bike is only slightly modded, never been overloaded and has always had both wheels on the ground which is why the stocker probably lasted so long but I changed it anyway, guess I'll just keep an eye out and check it every so often, after I get a replacement starter that is. | |||
