Hi,

I spent all day yesterday cleaning years of old chain lube and road grime of my recently aquired KR1s, very satisfying,

however i have a slight concern with the front sprocket, its wobbly.

on all bikes i have owned in the past, modern sports four strokes like zx6r's etc the fronk sproket is solidly mounted using a single large nut,

on the kr the sprocket appears loose although on inspection its not going anywhere as its securely mounted with the 2 allen bolts

can anyone advise if this play is normal

thanks

It should be tight on the splines ie no woble in the direction of travel. Womble in the other direction is normal as the plate is off set and holds the sprocket in place on the splines

Thanks Elf,

that sounds right, the wobble is left to right rather than front to back,

I would guess when you do experience play front to back this indicates wear on the shaft,

That puts my mind at rest,
