chain loosening on roundhouse swinger,wtf?

[volcrano]

hey guys,i got a stellar roundhouse swinger and modquad bearing carrier.ill move the eccentric to where the chain is tight,when i tighten the pinch bolts on the swinger its loose again.ive even had a buddy hold tension on the eccentric as i tighten the pinch bolts and the fucker still seems to move itself where it wants to go.why is this happening.its a pretty cut and dry set up?

yeah its pretty cut and dry ! are you adjusting the chaian while someone is sitting on the bike ? are you sure you getting the pinch bolts tight enough? put a line with a marker on the bearing carrier and the swingarm to see if its moving after you tighten it . like you said its a pretty simple set up. is the bearing housing clamping down tight on the carrier ? the bolts dont have to long of a shank do they ?

nobody is on the bike while adjusting lol.it looks like when i tighten the pinch bolts,the eccentric moves,like as the swinger is clamping down,the eccentric is following it.its pissing me off that i seem to be the only one having a problem with such a simple task.ugh.the bolts are what came with it.its like u need 2 people to tighten the fucker,i have no idea why it loosens as i tighten the bolts.like ill adjust it,tighten chain,tighten bolts,and as im tightening the bolts i can see the fucking chain start hanging more and more!i do wanna try put some other bolts in there and get rid of the allen heads for more ratchet ower,but like i said,as im tightening the bolts its loosening before i ride so,it might be on ebay if i dont figure wtf is going on.

Maybe spin the carrier 180* so that if it does try to move the same direction, it'll try to tighten the chain instead of loosen it.

thats weird pull the carrier and make sure theres no burs on it catching the split in the swing arm when i bought my swinger used the guy had a shim in there i believe he didnt have it tight enough and it was spinning and chewing it up cuz whem i got a new to me carrier it was fine

X2 the lobe is on the wrong side, the chain is loosening it. Spin it 180
