    Yuminashi cam chain &tensioner setup

    Ordered this whole thing only to find out days later that it won't work with a Koso 4v head. I have the chain, tensioner, tensioner rod and brass button. Just looking to get my money back from this. And you won't have to wait two weeks to get it from Yuminashi either. Only took them out of the box to take pictures.

    $50 shipped in the 48 states FIRM. Please don't bother me with lower offers. Thanks for looking.

    for some reason your tensioner unit looks different than mind. Mind has a curve up in the front where it mates to the cam sprocket, I wonder why yours looks different! I'm going to mod mind to make it work with the 4v takegawa head.
    Your's should work on a stock grom head


    That is what I'm going to do on mind is slow bend the tip down/semi-straight so it clears the cam sprocket in front and reduce the tension to the chain angle coming off the cam sprocket.

    Good luck selling your tensioner and parts, hope it sells fast

    Dammit Cisco, now you got me thinking about trying to fit it on my Koso head.... even though I already have a different chain and manual tensioner setup now. It would be a nice upgrade... then again I could get my money back from this... idk.

    Somebody buy this before I do stupid things.

    Philly your tensioner does look different. See if your chain fits between the rails of the tensioner. Vinny got a tensioner that was wrong and the rail guide width was too small for the chain.

    Sadly, you are correct.

    Guess I'll be deleting this post and suffering through trying to return or exchange this thing. This just gets worse by the moment.
