built my own swingarm

[old_chopper]

I built my own swingarm and it appears to be stuck. Yeah I know choppers kill and all.
Brace that arm up and test it. Check for stress cracks and if they appear try again.

[Jeepin it real]

to get back to the OP's dilemma, add some well thought out bracing, install, and go enjoy the ride. people have done far worse than you have. you have a good starting point just needs some tweaking

All the " flippin" used arms in the world and you cannot find an existing arm from a proven manufacturing company? Primary operating systems ( chassis, brakes, suspension ) should not be lightly "played around" with. I appreciate your pioneering mentality, I really do, but we're talking serious malfuction here with the arm twisting or folding in a corner. I had two Kaw Z-1's, I can tell you all about highs speed and chassis flex. Hell, the 82 Katana chassis was insufficiant which is why everyone blabs on and on about gusseting and bracing the thing and that was " technologically" advanced for it's time. At the very least, laterally brace and gusset the arm. Please?

In the words of Tony Foale:
"There are a number of so-called "braced" swing arms on the market, but sad to say, many of them are of no more than cosmetic benefit. A lot of the flexibility in a swing arm is due to twist of the pivot tube, and hence those arms that only feature bits of added tube along the sides are not going to help much. The final link in the chain that is responsible for holding the wheels in line is of course the front forks. Regular readers will know my views on these abominations, but if you must use them, they can be improved. If money is no object, go out and buy top quality replacement units with large stanchion diameters and a large wheel spindle. If you are stuck with your originals then fit a brace above the wheel, but get a good quality one or don't bother. Like alternative swing-arms there are many ineffective ones on the market, make sure that it is rigid and equally important it must be accurately made or it may distort the fork alignment and prevent free movement of the sliders. If you have the facilities then changing from the usual 15 or 17mm. diameter wheel spindle to a more rigid 20mm. one (like those on some Italian machines) can be quite effective."

What ever became of the swingarm project Nasty? How about an update?

Well Ed,

The naysayers planted too many seeds of doubt in my mind & rather than brace the arm & use it, I went with a Bandit swinger of known quality.
Do I regret it? Sure I do but felt it just wasn't worth taking a chance. If I hadn't had all the negative comments I would have installed it & at least tried to see if it would work. I'm not blaming anyone, it is what it is.
