this is interesting

i want to think its just me, but i now for a fact i didn't get this on the cbr 600. but any way...

riding the gs last night from work and i made a mad fast transition from right to left to avoid a dog.
now, when i did the front end wobbled after i stopped making the transition.   this was at a bout 60mph

so after this happened i was like what the hell. so i did it again but not near as ruff on it. it it would still do it. so buy that time i thought the bearings were going out or the front end was loose.

i get home and check it nothing is wrong, or did i get use to riding the cbr 600 and i am back on a gs that does this.


don't get me wrong, it wasn't like a death wobble just enough that after you move the wheel (with some force = spirited riding) that it would wobble.

also it felt as if i was riding a land barge, slow ( ) ,really soft front end, and slow to turn in which made it unpredictable at faster speeds.  kinda like driving a two wheel caddy (the old ones)

yea i'm curious about this too. I havent had any bad wobbles from the front end yet, but I would really like to know what may cause it, how to stop it, and how to avoid it. I was reading on SBN a few days ago & someone mentioned that he had a bad tank-slapping wobble on his Kawasaki EX500. A bunch of morons on the site could only offer the advice of buying a $500 steering dampher for his little bike. probably complete overkill. it seems pretty rediculous to me...

Tire pressure?

[rangerbrown]

just checked it. the front and rear is at 38

Are those the cold tire pressures?  As in, you haven't ridden it, yet?

If these are cold pressures, lower the front to 33-34psi to increase your contact patch.

Putting more weight over the front end helps plant the front tire more.  Suspension set-up helps this as well, as ride height.

What setting is the rear shock at?  If you can, increase the preload; this raises the rear and biases more weight forward.  It also steepens steering angle and shortens trail (castor effect).

Sliding the forks up through the triples to lower the front end does the same thing.  Try 1mm at a time.

Suspension set-up: www.peterverdonedesigns.com/introduction.htm

Do you have enough travel in the downward direction?

[rangerbrown]

yea those were cold psi.

i think the rear is setup like stock, the middle as i read. my weght is 220 and 230 with gear +- a few

I am experiencing something of the same and I was hoping that is due to sucky stock fork springs and would go away when I install stiffer springs. Do you run stock springs in your forks?

Rodger on it being sucky stock forks.

The feeling you're getting is the same as mine before I re-did them with 15w oil.

You hit a little THUNK and it wobbles a hair. thicker oil makes this happen much less.
