    Swing Arm Removal

    My chain master went out and I now have a ball of a chain mess at the counter sprocket. I tried winching it out but the way it's knotted up just won't work. Are there any tips/tricks for dropping the swing arm?

    Thanks for any help!

    Removing the swingarm isn't a massive job but it is a bit tricky. You need to suspend the bike from above so that it is hanging. Remove the wheel and the small plastic cover that holds the brake line in place.
    Remove the shock and connecting rod linkage. To remove the swingarm rod/pivot you will need a special tool which also doubles to remove the engine bolts. Once you have the tool it comes apart easily, just remove the nut, unscrew the rod and use the tool to loosen the bush.
    If you have never had it apart, the swingarm bearings will probably need replacing. Mine were toast after 40k k's.
    Did you manage to remove the front sprocket from the output shaft? Could you use a small grinder to grind down the pins on the chain, remove the faceplates and dismantle it? Sounds like a real mess

    Yeah.... It's ugly to say the least. I haven't tried cutting apart the chain. It's such a narrow space to work in. I'd rather save the chain if possible. I do metal art on the side and chains are always cool to work with.

    Yup. I was on the on-ramp to a freeway and on the gas hard when it let loose. I'm damned lucky that it happened while only doing between 50-55 mph. If it happened when I was up to usual highway speeds (90+) the result would have been really ugly.

    You were lucky- use a small angle grinder to cut off one of the top links

    Don't be a cheapskate.
    It's an Aprilia.
    It deserves to be well maintained.
    Cut it off.
    If the master's failed, the rest can't be far behind it.

    If you go to most bike shops they will give you an old chain.

    Was it a rivet link or split link; never seen a rivet link let go before and I hope you didn't fit a split link.
    What make of chain?
    Fingers crossed there's no crankcase damage.

    The castellated socket to remove the swing arm fastener can either be made by finding a socket of appropriate size and taking a grinder to it - no biggie for a metal guy like yerself - or going to a bicycle shop and getting a freewheel tool, as it's called. Check the size, of course.

    Little note: the engine fasteners are similar but smaller.

    Leave it like it is and you've got art.
    Although more performance art than fine art.

    I'd call it a 470 pound paper as it sits right now. LOL

    I ordered one on ebay that is coming from the UK. I did weld up my own spring puller for dealing with all the springs on the exhaust but didn't want to go to the headache of notching a socket with an angle grinder. I don't have a mill either so I figured why not wait for 2 weeks to get the tool rather than possibly dorking up a few sockets until I got the right fit. That and I need my trailer this weekend and the bike is on the trailer. It would be tough to deal with that bike if it were in pieces. LOL

    I'm picking up something very interesting to work with. I wouldn't call it art but damn fine material for man cave tables. I'm getting 9-10 Lamborghini race rims.

    I don't have the rims yet but I did create this desk lamp from parts from the same race car.

    This desk lamp was created with parts off of the #08 Yokohama - West Racing Team GT3 Gallardo. The car competed in the ALMS GP series and was featured in the Forza Motorsport IV X-Box game. A caliper forms the lamp top, 2 suspension components form the supports, and the base is an incredible cnc machined billet piece from Reiter Engineer in Germany (unused part so it is in pristine shape).
