BMI doesn't work for <40 athlete builds very well. Works for me...I'm 5'11" and 180lbs. I am definitely 15+lbs over my healthy weight, and I'm working on it...I'm 51. At the last Ironman race I did (2006), I was at 158lbs and still had plenty of body fat.
Little update. Thanks to the Chaparral parking lot sale, I got the ASV sag scale and the ASV bike stand really cheap and now I can do the sag by myself. Spend about 2 hours working on my sag this weekend. Had to use a punch/screw driver. If someone can tell me how to do this with a spanner wrench that would be great. I couldn't get one to fit. Got it to about 102mm. End result? The same on the rain grooved freeway. On a good note, I can now flat foot while stopped. Checked the chain alignment, and front wheel alignment, both are okay. At this point, I'm not sure what else to do. I did take it 1/2 way on 1N34 and to 3N31 to Lost Lake and off road wise it's fine, for me. And tar roads I went about 65 mph and didn't feel any wobble. Maybe it's just the tires?
On mine ... it WAS the tyres. They were way out of balance. Now they´ve been re-done ... wobble gone!
Punch/screw driver and a hammer/mallet is about the only way. You might be able to get a spanner in from the right side if you remove the airbox. But, to me, that's more trouble than it's worth.
New front tire, perfectly balanced, sag at almost 4", still wobbles over 65...kinda scary. Dropped the forks all the way down too.
Set race sag to 100mm shortly after buying my 630. Bike still wobbled at any speeds over 110 KM/h. Static sag was 52mm indicating much too stiff rear spring. Replaced stock 6.4kg/mm spring with a 5.4 kg/mm over the winter. Same race sag and static sag changed to 35mm (ideal is 25-35mm). Replaced front springs also. Bike is much more stable with no hint of wobble at any speed. Same tires and pressure. Stock rear spring on these bikes is OK for a 260+ lb rider or maybe two small ones. I am 6' 180lb.
I'm 6' tall and 195lbs. My TE630 has Pirelli MT-21's front and rear (sizes, 140/80 & 90/90). The tubes have Dyna Beads in them for balance. My suspension has not been touched at all. She runs nice and straight with no wobbles or side to side movement all the way up to an indicated 101 on the speedo . I wouldn't recommend triple digits for long on the Husky, it's a little scrry at those speeds . The oem Karoo tires had side to side movement above 70mph. Odd for a much less aggressive dual sport tire. Go figure
Long ago, I discovered to my horror that the new-to-me R100GS would get all squirrely on rain grooves. Eventually I learned to tolerate it 'cause the bike wasn't going to go down. (sure me me tense up tho) Then I changed out the Metzeler street tires that were on it for Avon Gripsters (similar to Mefo explorer) and suddenly, no more squirrelyness! So I think it's the tread pattern and rubber hardness that determines whether a tire is going to try to hook into the rain grooves.
Holy you know what. Had mine up to + the century/ton mph indicated and nothing. Changed the counter sprocket and will only do less than century and nothing. Came with the karoos the rear is gone after 1200 miles and replaced with a D908 and ran it up to close to top speed and smooth. But did not get in any grooves, so who knows.
my tires are balanced, Pirelli DOT trials at 22psi for the street, sag is 4". it is fine on regular pavement but still hates the rain grooves, with wind it really sucks. never was a problem on the 610.
With stock Karoo's I did some long distance cruising at high speed, 70-80mph and never experienced a wobble. Checked speedo memory and had reached a top speed of 85mph. Installed hand guards, put tire sealant in both tubes and at ~1,900 miles on rear Karoo I started noticing a wobble could be induced at 77mph and came on hard by itself and irreversible at 82mph. So thinking the handguards and sealant were the culprit didn't do anything more. Then I changed the rear tire to Kenda 90% dirt tire and added a rim lock on rear. Did only a guesstimate wheel balance by counteracting the rim lock weight with an equivalent 2 ounces of spoke weights opposite side of the rim. Wobble is now completely gone, up to 96mph before I backed off the throttle and bike still as planted as can be. So I have added many things that are believed to contribute to a wobble without any wobble materializing; i.e. rim lock, dirt tire, tire sealant and handguards. I have to now believe it is mainly the Karoo rear tire and especially a worn Karoo that is causing most people's problem. _
I'm beginning to think it's the rear that's creating the wobble as well, although once I got my front end all lined up it seems to have gone away. I also noticed that measuring from swingarm pivot to axle the alignment marks were not accurate. I aligned it by measure but then it looked a little cockeyed when viewed from behind. Once it gets close to a fraction of an inch it's hard to eyeball it anyway. But I don't have any wobble any more up to 85. At that speed the front tire is a little too flighty for me with the full knobby, so comfortable speed is 65-70. I'm pretty much resolved to keep it mellow. Running at 100+ with a 990 or something like that with knobbies is not my cup of tea. Now, the street bike? That's a different story.
Also forgot to add when I did 96mph on the Kenda 90% dirt tire it was very worn (near slick) same as the Karoo was when wobble first started. Put a new tire on today, cheapo Cheng Shin C858 60/40 tire as I will be racking up ~2,500 asphalt and dirt road miles the next few weeks. That many miles would burn through 2-3 of my good dirt tires. Anyway did a quick run tonight to start scrubbing in the new tire and got it up to 90mph before backing down. Rock steady, no wobble whatsoever. Didn't even balance the tire either.
I noticed the marks aren't right on my swingarm either. I bought a MotionPro alignment tool and use that instead of the marks now.
this. My suspension is dialed, the bike is ready to go....offroad. Grooved highway and knobbies - that dog will hunt
OP how long have you been riding? FOr riding dirt/off road I would think you would be use to the bike not being stable. .. I get the wobbles too .. not consistent. But it all depends on the groove and road.. my sag is set and forks raised to get it as stable as possible.. Its the forks that has no compression setting that is screwing things up.. its my only grype for this bike so far.. C'on a drz has compression adjustment.
I also strongly suspect rear tire being the culprit of the wobble. My bike has now about 6000 km and is on its third rear tire (front still original Karoo being replaced as we speak). With the original rear Karoo the wobble was there very clear at the speeds over 120 kmh - luckily it was gone quickly and I put TKC80 at the back (and installed Lynx fairing - probably did not affect it as seen with the third tire below). Did two trips - 9 days in Mozambique about 2500km and 4 days in Lesoth about 1500km with deep sand tracks, hardpack dirt with embedded rocks as well as long distances on tar at sustained 140-160 kmh (not fun), and there was no wobble at all - regardless whether the tire was new or almost gone. Now I put on Mitas E09 (the most knobbly tire with quite hard compound for long life) and the wobble is back big time. I have not touched the suspension or sag - I know, it's getting done next week be somebody who knows what he is doing.
One thing I forgot - on those trips with TKCs I had quite a lot of luggage at the back (in soft panniers and roll-bag at the top), including 7 litres of petrol. Total may have been over 20kg. Not sure, but may have had an effect on the wobble. Cheers
