BansheeBrian Posted December 4, 2005 Report Posted December 4, 2005 I need to straighten out my subframe so I can send it to powder.What is the best method for straightening?Rolling my shee down a hill was the culprit. Quote
PUSH THE THROTTLE Posted December 4, 2005 Report Posted December 4, 2005 Roll your shee down the same hill but use the oposite rotation. Never had to straighten one but I'd guess you'd have to get some prybars and work it till it's where you want it. Quote
WNARACE Posted December 4, 2005 Report Posted December 4, 2005 Depending on how bad it is tweeked, I had to straighten one on an automotive frame machine. After several attempts to bend, pry, and twist in the home garage. Those frames are much more difficult to get back into shape than what I had antisipated. Good Luck!! Quote
NYUK Posted December 4, 2005 Report Posted December 4, 2005 just use a long piece of pipe that fits over the rear subframe, grab bar removed.bend it whichever way it needs to be bent back. Quote
reded Posted December 4, 2005 Report Posted December 4, 2005 Usually a 3-4 ft piece of pipe and a large deadblow hammer will get em back into shape in no time. Quote
BigRed350x Posted December 4, 2005 Report Posted December 4, 2005 Just get an oxy-acetaline torch and heat that guy up to red hot on each of the mounts and you could bend it back real easy, then just douse it with some room-temp water so you get your strength back. You don't want to use really cold water or you risk it cracking. Quote
2twin350s Posted December 4, 2005 Report Posted December 4, 2005 cheater bar has worked for me. you can also use a porta power hydraulic ram kit. but you will have to chain or bolt the frame to the floor.or if the bike is all together yet, you can put the porta power between the swingarm and sub frame,use blocks of wood so you do not crimple the tubes on the bike,and start appling the pressure to the ram. they work good and you dont break a sweat. you can prolly rent a porta power at auto-zone or napa for 30 bucks.

BansheeBrian Posted December 4, 2005 Author Report Posted December 4, 2005 I will try NYUK's method then I'll give Reded's a shot then try 2Twin350's a shot then will try what BigRed suggested then if all else fails then I'll resort to P.T.T's crazy idea. It's tweaked pretty good.I wish uncle NYUK painted his A-arm frame gloss black.I would have paid a good price for it.If things don't work on this frame Fire a PM my way if someone has a PC black frame in mint condition.I have plenty of $$$.

dawarriorman Posted December 4, 2005 Report Posted December 4, 2005 I would save the torch for a last resort. Doing that will take the temper out of the steel, and you will not be able to get the strength back. Tempering is more than getting it red hot, and then pouring water on it. All that does is make it extremely brittle. Automotive frame machine would be your best bet. Shouldn't cost too much either if you look around. Quote
BansheeBrian Posted December 5, 2005 Author Report Posted December 5, 2005 Even if I used the torch I would let it cool down on it's own.I don't want to mess with the frame too much.These frames aren't made of the best steel.I think Yamaha skims off the top of the pots at the foundrys and uses that.Like the fat in a cold pot of soup.

Shee-Male Posted December 5, 2005 Report Posted December 5, 2005 a big bar and an extra pair of hand always works for me, depending on were and how bad its tweeked you may have to cut and reweld some of the gussets. But deffinatly keep the tourches away from yur frame just like dawarriorman was sayin!! Quote
smkmupbanshee Posted December 5, 2005 Report Posted December 5, 2005 We used a winch and some big pipes to flex my buddys frame back. We layed it out on a table and bolted it down and pulled it from there. It worked good! Quote
PUSH THE THROTTLE Posted December 5, 2005 Report Posted December 5, 2005 Plenty of money could get you a brand new LE frame for like $550 at the stealer. Heating it up and quenching it will take out the ductility and it will crack in the future. Cold work it with some bars, pipes, winches or porta power is your best bet. Quote
fast500#12 Posted December 5, 2005 Report Posted December 5, 2005 4 foot pipe and a buddy to stand on the axle if installed if not sit on the frame. worked good for me. mine was like 4 inches down on the right side a 2 and ahalf on the left after it went end over end 6 times Quote
