Puch Maxi pedal chain rubbing on swingarm

Why is this chain rubbing on the swing arm? Is the front pedal sprocket too small or the rear wheel sprocket too small or something?

Or maybe the shocks are too short?

The rear sprocket is smaller than stock

yea. im not sure mybe some bicycle freewheels fit? it's actually kinda cool tho. I doubt it'll doo much damage and if you can actually pedal at speed, that's always pretty rad.

Take the wheel to any bike shop that sells/repairs bmx bikes. The pedal sprocket isn't anything crazy, and they should be able to match it up with a larger one to space out that chain.

The rear stock pedal chain sprocket is a 23 tooth and when changed to less they do that.....

I'd fab a guide or rub block to fit on the swing arm .

The chain slips off a lot when starting the bike.

Have you checked the chain alignment ? Should be a straight shot front to back .

Or does the chain have a side way kink from being jammed off the sprockets ? (edited)

Its straight, the bottom chain guide is loose, maybe i need to make the chain smaller since its a smaller sprocket.

Re: Puch Maxi pedal chain rubbing on swingarm

From that last pic , the chain looks plenty dry with possible 'stiff' spots .

A few stiff links could help toss a chain .

Taking a link or two might not be a bad idea . That depends on how much 'swing' your bike has .

Re: Puch Maxi pedal chain rubbing on swingarm

Your pedal chain tensioner is v loose. Probably need to take a link out of your pedal chain so it won't flop off of there. Your tensioner might be a little bit tweaked now too, who knows?
