    I recently purchased a 550 Seca, which had been sitting for a few years. I've been trying to get the bike to roll, but the back tire is pure deadweight. I've replaced the clutch cable and the swing arm wasnt moving, but fixed both of those. When I put the bike in neutral or in gear, I still can move the bike. Any suggestions would be much appreciated!

    Sounds like the rear brakes is locking up,make sure that the linkage is moving and check the adjustment,you may have to pull the wheel off and inspect the shoes.

    The pin that goes through the rear brake faceplate might need greased and could be preventing the spring pressure on the shoes from pulling the shoes off the drum.

    Thanks, everyone. This forum has been a real life saver as I try to figure out how to get this old bike back on the road. I'll see if I can get the back wheel off and see what the issues could be. The rear brake pedal is really stiff, meaning I have to pull hard with both hands vertically up and down to get the brake pedal up and down. Any specialized tools needed to get the back wheel off? I have the bike on the center stand now.

    As long as the axle shaft isn't frozen into the wheel,if it is you may be looking at some trouble,what worked for me is what is called a pitch fork or ball joint remover tool that you should be able to rent at a auto parts store.

    If he puts a piece of timber either side of the axle shaft on the brake shoe side he should be able to press it out if he has a vice and suitable drift.

    Or use the timber as stated and hammer it out with a copper faced hammer.

    Follow up question here. When I was moving the bike as dead weight, I took the chain off and the back wheel moved freely. Does this still sound like a rear brake issue

    Of course not,sounds like a internal transmission issue.

    Take the sprocket cover off the engine. The chain might be jammed between the cover and engine sprocket. Make sure the transmission is in neutral.

    It is a new bike to you.
    You must check the brakes... stopping is more important then going.
    Just sayin’. ;)

    Happened to my CB750K2 but the chain smashed the cover. I was lucky it didn't smash the crankcase. Don't have to bother now because l have a 900f :D.

    Hey everyone thanks for the comments. I've taken off the sprocket cover and the chain still isn't budging. Here's a quick peak inside. Not sure if it's from the rust or something else. I also cleared out the crud in there (looks like plastic tape). Any idea on next steps?

    I agree you need a new chain and sprockets.

    Once you get the old junk chain off try and move through all the gears and as the guys said renew the chain and sprockets. Chain is rusted solid those links won't move.
