Found your forum through a search engine and hope you can help!

I have recently bought a 1990 Kawasaki EN500.This is the early Belt-Drive model.
True to form and just my luck when investigating the creaking sounds I get when riding I found out the belts about on its last legs,with lugs missing and small cracks in evidence...Kwak want 319 pounds for a replacement OEM...Scooterworks in the States do a direct replacement for the OEM at a sizzle over 130 quid.... Shocked *Gulp*
This was supposed to be my cheap runaround for the not so nice weather(Have a Thundercat for fun-days).
I've heard that it's possible to convert to chain drive i.e gpz500 and later models of the en500 etc...
Does anyone know what this actually entails/is required to be purchased to do this please?
Apart from the obvious problem the bike seems quite a hoot to ride and if this could be fixed slightly more cheaply I'd probably keep this indefinately!

Take the belt to one of you local bearing factors. These usually supply drive belts.
Like bearing much cheaper than your average bike shop Thumbs Up

Yeah thanks,I'm trying this at the moment....no luck so far but I'll keep trying!

The scootworks option is still to expensive I fear....

I've sourced a rear sprocket carrier and laying the belt carriers away safely I'm going to attempt the conversion.....looks like I might have to source/make a spacer for the front drive sprocket though...it sits differently to the belt carrier......Anyone know if it's the same on later EN500's?

I've just had a look at the two output shafts and it looks quite possible to convert the belt drive one to run with a sprocket rather than pulley. The shafts look the same apart from the way that the pulley and sprocket are held in place. The drive shaft off the chain driven bike has a threaded end while the belt drive one has a flange fitting. You might need to have the right sized spacer made up or you may get lucky and find that the one on the chain driven bike is the right size. Next thing you'd need to change the back wheel and make sure the chain lines up.

These belts are fairly specialist and you'd be lucky to get one from a normal belt drive manufacturer. The fact that they're so expensive is one reason belt driven bikes never took off and another reason I gave up on thinking of converting a chain driven bike to belt drive too Sad


Thanks Vincent,we're okay with keeping the original wheel intact only minus the belt carrier,the cush drive is the same as that of the sister bike gpz500 so we've sourced the carrier and a rear sprocket which sit perfectly in the swinging arm.The front sprocket was my main concern as you said the later types are somewhat different.......However..the gpz500's isn't as they were built at the same time they use a similar sprocket fixing Very Happy ...To line them up though now we've mocked it up definately requires a spacer to position the front sprocket at the far end of the gearbox output shaft! I'm hoping to have something knocked up in the next few days so hopefully the next time I'm here it will be good news for a change Laughing
Thanks for all your suggestions,nice to see a place like this exists!
