Title: Instability
Post by verslagen1 on 05/26/09 at 20:12:44

So I rode the '8802 to work today.
The bike feels fine except the rear end doesn't want to follow the front.
Haven't got the fork brace on yet cause I'm polishing it up.
checked the front bearings felt good
checked the rear same   :o
slow turns feel wierd, turn alittle and she wants to turn alot.
slight turns feel wierd too, maybe like a damper would if I had one.

BTW, I swapped the brake line for a stainless steel braided line and they feel great.  With the old line the brakes were really spongey.

Oh and I checked alignment, walked it down a straight line, it's aligned.

Just a guess. Underinflated tire?

13 in front
18 in rear
I'll give that a try.

Sounds like my '07 S40. At low speeds it wants to "fall into" a turn. My old Suzuki Tempter had a little of that characteristic, too. Once the turn is initiated it requires pressure on the bars to keep the turn from increasing. When the speed increases to maybe 15 - 20 mph the quirk seems to disappear. My S40 has the short drag bars (stock) and I think their shortness makes the "fall in" seem more exaggerated, because they give less leverage.

check your spokes? crab walking can be rims out of true....

Aired up the tires and put the fork brace on, we'll see how that works.

Don't think it the rims out of true, they look ok.

swingarm bushings?

Well it was either the fork brace or the tire pressure.
I don't know how you guys w/o 'em do it.
Felt like the rear was trying to pass.

i thought mine was feeling a little extra "hoppy" i think it was all the heavy rain on my belt(mine is outside under a cover)

but after a minute of so she straightened back out, i'll check tire pressure as well.

i don't have enough riding time to notice things like this, but i do know i'm making progress because cruising @ 60 feels normal whereas around the block used 2 be a challenge lol

Good to hear the fix was nice & simple!!!  I like those.

Rocco: Good to hear your confidence is growing. Just be careful. At 60 mph $**t happens pretty qiuck!!!  A couple of good hiway trips will do you good. It did for me!!! ;D

this is true! i feel comfortable enough on the bike so now i'm not thinkin "clutch....throttle....foot....how fast am i going?" lol now i just go and watch everyone and make sure they stay on their side of the line(easier said then done in south fla haha)

a friend of mine who has a custom and a vulcan, mind u his custom is 1900cc...totally rodded out, his clutch was a pain to pull in...he asked if i wanted 2 ride it, i declined of course! but he said that u should be comfortable with how to operate the bike, but never so comfortable that you're not a little cauteous of what damage u can do to yourself. he kind of explained it as being a little scared and a little smart. i think that's a good philosophy!

i then told him "remember you're naked and invisible" i saw that as someone's signature on here, and he laughed and said that works just as well!!

we have an affiliated school in lake mary fl, i think it's about half an hour south of orlando. i've been contemplating taking the turnpike up there for a weekend of kenpo and 2 wheels.....i can't think of a better way 2 spend time!! below is a picture of our crest, does anyone else here study a type of martial art? if u agree and think our crest is cool looking i'd be more then happy 2 explain each piece on there, my instructor designed every little detail to mean something!

and yes i'm way 2 passionate about my art lol but being obsessive is good right? i think riding is becoming a very close second!!

sweeet! that's a "style" i believe, hard as in linear soft as in circular!

i bet you remember more then you think! we have people come in all the time and say "i haven't done anything for 10 years" then 15 minutes later they can stumble through a form or technique and they don't know how lol it's amazing when u think about it!

muscle memory... 2000 clean reps of any movement, and your brain lists it as a "canned cycle".... an auto-pilot manuever, if you will... that's why you practice stuff like panic stops, emergency zig-zags, martial arts forms, fast draw, etc.... if the codgers that stumble through the remembered moves were in the same physical condition they were when last they practiced, the forms would probably be much more precisely executed....

It is almost unbelievable how much difference just one or two pounds of air will make. If you have the time I would suggest a test.
Put the correct pressure in your tires and ride some residential streets at night. At night your body is much more attuned to “feel” than during daylight. Then drop the air by five pounds and ride the same roads. Then drop the air another five and do it again. I can pretty much guarantee that you will come to believe that your suspension is failing.  On a light bike like this, just surface temps alone will make a diference in your ride. Always suspect your tires first...your usually right!

pretty much guarantee the air pressure had more to do with it than a fork brace.  Wiggly handling is usually a dead give away for low pressure.

Ride home was way better than yesterday, but still feel unable to ride a line.
I suspect it's due to the stiff steering preventing me from making micro adjustments.

Ver,

Your steering head bearing races may be notched.
