Title: Need to Straighten Sub-Frame
Post by: scootr9718 on October 25, 2005, 11:45:36 AM
I had a low-side a while back, followed a few months after by a tip-over...I don't know which caused it, but the sub-frame is bent slightly to the left on my bike.
I have an estimate from the stealership for $80 (that was with them doing other work which included replacing the back plastics..)
so I figure, if I take off the back plastics, doing that labor to get the bike bare, they should honor that quote...
anyone know if that's a good deal? or if I should shop around, maybe try to do it myself with a 2x4 wedged between the tire or something? I don't know? :dunno:

$80 isn't all that bad if they do a good job.  Putting my freak rear tire on cost me $40 (i'll be doing the next one myself)

Sounds pretty reasonable to me.

That doesn't seem all that unreasonable for me, considering how much work is involved.

Of course, you always could do it yourself. Don't lever it against the rear tire/swingarm though.  You want to isolate the torque you are applying to where you want it, not bend the swingarm too!

A friend of mine straightened his by wedging the bike between two trees and then using a metal pole to tweek the subframe back into alignment.  That is the beauty of steel over Al.

coulpe of years ago....(this one time...at band camp...)
I loaned a spare bike to a riding instructor....
he cartwheeled it at about 90
the subframe was seriously bent..the last 12 inches were bend straight up on one side
i tied the bike into the back of my truck with 8-12 tie downs....tripples, frame, swingarm
I cut the subframe supports seperating left/right standing behind the bike
beat the crap out of it with a sledge hammer, long pipe and a 2x4
then welded the supports back together
i was able to install stock tail plastic
we then endurance raced it for a year....
and then it came in 2nd in nation in vintage 3 yrs ago
then we found out it had a bent swingarm from a couple of yrs prior
....blah blah blah
