I just went and bent my subframe on my wr125. How can I straighten it? I want to get back on the track... ):
A good whack with a dead blow hammer should fix that. Or stick a length of pipe over it and bend it back.
I would use a blow torch to heat the area you need to bend, aluminium has a tendency to crack when bent cold. Dont overheat it or you will end up with a puddle of metal, put some vice grips or similar on the end of the frame and heat until you can bend it back under your own power, i've done this on subframes with good results. Each time you heat ally it weakens so you will only get away with it so many times, just don't fall off again!
Yeah a friend of mine told about the blowtorch also. Too bad I don't have one at home, i guess i can't get it nice and orange with a hot-air blower?
A hot air gun won't give enough heat plus aluminium won't go orange it will go white then melt that's why you shoud heat and bend at the same time, just needs to be the type of gas torch a plumber would use, nothing special, sure a friend or neighbour would have one in their shed.
okay, wouldn't know anything about the colour of aluminium when heated just wouldn't want to rush or do anything sloppy, because a new subframe costs a lot of money. Atleast to a student...
Don't heat it. Just smack it around with a wooden base ball bat. That end of the subframe is super soft and will move easily. Later George
I had the same problem and a friend just put a blow torch against it and heated it up and after 30 seconds he took a big monkey wrench and he put in place again. Heat it untill it bents like a candybar (but not to much because it will lead a life off it's own :-)) ) Let it cool down and nobody will notice a thing .... Best off luck
Mine looked just like that after a race. I didn't even take the fender off, just hit it with a deadblow some. It's not perfect but my fender is straight(er) now. That piece does nothing unless you had a taillight bolted to it or something.
Thanks guys for advise! I just decided to take it off, put it into a vise and turn. that turned pretty good, and it's now better than new (kind of) Thanks!

Just bend it back. I did the same thing a couple years ago. You will be fine. You really don't need to spend serious $$$ it get it fixed.
That looks like a forged part. I think heating it may permanently change the hardness. If the part was heat-treated after welding any additional heat will FU the heat treatment. Aluminum alloys depend on being properly "tempered" for strength. Different temperatures for different properties. More than you want to know here: http://www.engineersedge.com/aluminum_tempers.htm
