Title: rubber frame?
Post by wambr on 08/14/13 at 09:02:58

recently I began to appear a strange feeling as if the frame of my Savage was of a rubber. sometimes turns under my tushy felt vulgar wobbling rear wheel... what could it be? these are signs of "death" bearing of the swing arm? what do you say guys?

Check the air pressure in your tires before going anywhere else with this.

32-35 psi is about right in the rear, front should be 35-37 psi.

Less than that gives you the "squirrelly feeling" when you manoeuvre.

Ive called mine a Drunk Rubber Cow for the oscillations it goes thru in a long sweeper. Ive got one I just cant get thru at over 65, It starts see sawin the bars & the rear end feels like its goin up & down. Thats where the throttle stops twisting,,
Ive thot that whats happening is the road rises & falls enough to cause the shocks to work, changing the rake angle/steering geometry enough to create the handlebar wobbles..

Ive looked at the swingarm, I cant Feel any play,, but, one guy may not be able to get the bushings loaded up even close to what theyre getting from the bike & rider swinging thru an arc at speed..
Of course, check spokes,.
If you arent set on Firm in the shocks, Id do that,
Have you done anything to it that Could affect handling?
Remove rear wheel?

Agree with Oldfeller, tire pressure before ANY other concerns. Rigid frames I run 30-35 psi in the rear, 35-40 in the front. Swingarm frames I run 35-40 psi front and rear.

29 is about what the book says for the front. If you are going to experiment raise the pressure in two pound stages

Same thing for me? That description sounds like tires? I can come the other way, makes it on camber a little, & with the tighter radius I can exit at 65 & not be scarin myself & its not wobbling,

I installed a T-Kat fork brace on my RYCA and cleared up the oscillating-in-a-high-speed-turn problem about 95%. It is not scary anymore, but since I was really sensitive to it, I can sort of sense it is still there, but it never really develops into something definite.

What is the condition of the road you are riding on? I have a road that has groves cut into it and mine feels like one tire wants to go one way and the other tire wants to go the other. Once I get off that road it doesn't have any problems.

Actually I cant SEE a thing that makes me condemn the road, But, thats the only place where I have that I can make that kinda speed in a sweeper like that. I really cant say it is or isnt the road. I just find it odd that I can come back thru headed the other way & hit speeds that start makin me nervous before the bike acts up & there are plenty of places I can not Just get a peg down, but Down so far as to get my foot in a bid on the motor & have to pull my foot back to get out of that bind, The rubber on the right side is tied together underneath with wire & the end caps on both sides are cut away to the main body at least, on the right, somewhat into the main frame.. to the point that if I drag it much more the end cap looks like its gonna let go. The little bike will make a corner, & feels plenty solid doin it, Its just that Oooone place that scares the heck outta me,,

thank you for the tips guys! I checked the pressure in the tires and the spokes of the wheels... all in good condition, despite age of my savage(it '95) wheel bearings, too, seems to be within the norm(at least I have nothing bad to not noticed).
I was left with only two versions - bad bearings rocker arms and already aged rear shocks(although his work cope)...
