    Bent frame and cross brace?

    So I just picked up a pretty clean '68/'69 CL350. Now that I'm digging into it I've started to notice a few issues that I naively didn't notice before.

    It looks like the frame is bent a bit by the motor on the left hand side of the bike (right near the kickstand - see first picture). What is the best way to get this straightened out, or do I just leave it as-is?

    Also, something looks a bit off on the foot peg mount/frame cross brace. Not sure if this is because of the slight bend in the frame or if this piece is bent too, but it touches the motor on the right hand side of the bike (left side of second picture). I'm assuming this isn't supposed to touch here. Again, any recommendations on how to straighten this out?

    Thanks,

    Something looks to be going on there... and in the second picture, it looks like your lower case motor mount lug on the bike's right side (left in the picture) has been cracked and welded too. Centerstand looks to be leaning backward a bit much as well... does the rear wheel touch the ground while on the centerstand?

    Yes, you have a bent frame. Red at Cycle One Manufacturing is one person that I know can repair it.

    Yeah I noticed the cracked mount when buying, but didn't think it was a huge deal at the time. Don't know how I missed the bent frame. With the center-stand up, the rear wheel is off the ground.

    Thanks for the heads up. It would be nice to find someone more local, so I wouldn't have to take everything apart and ship the frame. Is this bad enough that it definitely needs to be fixed before riding?

    If both wheels are still in the same plane and it tracks straight when you ride it, I would be inclined to leave it as is, at least until this years riding season is over. Straighten the frame and that welded-up front motor mount lug probably won't line up and you will have to deal with that also. Used frames on ebay start about $135, shipped. No titles(of course), that opens up a different can of worms.

    This is good to hear. I was really worried once I noticed the bend. Any ideas on how the mount would have gotten broke? Someone laying it down hard enough to bend the frame and break the mount?

    A trick my auto body repair father taught me is to have someone ride the bike toward you at a moderate speed (fast enough to keep a straight line, slow enough to give you a decent chance to take a look) while you squat down and "sight" the front tire against the rear tire, and vice versa while going away from you, to see if the bike "dog-tracks" or if one of the wheels isn't perfectly vertical (as in a possible swingarm tweak with the rear, possible frame neck tweak in the front). Provided the chain is running true (rear wheel straight in the driveline), if something is off enough to matter you can usually see the misalignment. If the lower tube being bent has had any effect on anything structural overall you might see it this way, but I'm not sure your situation is enough for that to be the case. Couldn't hurt to look

    Awesome! Once I get her running again I'll give this a try. Thank you.

    Any thoughts on the brace rubbing? Is that going to damage the motor case?
