    Sorry I'm looking at the pictures from my phone .

    Is the chain rubbing up against where you are pushing it into with your fingers?
    If that :
    Was going to say add a chain roller but that doesn't look to be the issue .
    Other thrn doing somd swing arm cutting and modding ..The only way I figure to get the chain further away from the swing in that part is to maybe add a washer to the sprocket side of the axle between the spacer and frame .

    Yea its were my finger is pushing it. If i thighten the chain enough it wont hit but then its way to tight. I was thinking about using the spacers but will that effect the bike if the wheel is favoring one side. That pic wont help prob but i dont have any of the other side currently

    Really nice bike..

    Maybe there is a way to add a thin Delrin plate to that area of the swing arm to protect the swing arm from the chain rubbing on it...but you'd have to make sure the chain would not get snagged on it when the swing up compressed etc..

    Is there such a thing as a slightly offset rear Sprocket?...Maybe a rear sprocket the gets the chain slightly closer to the wheel..

    Otherwise I'd try one washer to that side just to see if it makes it better..

    You could certainly get a pice of cutting board, file a couple notched in it and zip tie it to the swinger as a makeshift slider. Have done it with good results and if you do it nice it looks good as well.
    What gearing are you running? Another, probably better but more costly option would be to go to a smaller rear sprocket. If you go down 3 teeth in the rear and one in the front then your gearing will be virtually the same.

    Is it possible that you have the wheel spacers on the wrong sides of the wheel?

    I like the cutting board idea. Im thinking its the chain. The chain is stretched bad and real sloppy side to side. I have a new chain coming so ill go from there. Thanks for all the help and suggestions guys.

    I was going to say,maybe your chains worn out...

    Make sure to lube your chain well..


    Not sure how you lube your chain but :seems when I use certain lubes they thicken up on the chain and I get slop..
    Now I know you have to clean,lube your chain ,just saying that a good stick on lube may prevent 'some of the future hitting of the chain on the swingarm
