Title: 48 speed twin crank nut (sprocket side)
Post by: mikebike on October 19, 2007, 05:33:24 PM

Hello world, can anyone advise if the thread on the sprocket side of the crank is left or right hand thread. Mine is very tight !!

If in doubt it is best to work it out.  When you turn the engine with the kickstart, what direction does that end of the crankshaft rotate? Left hand threads are used  in situations where the normal rotation would tend to encourage a right hand thread fixing  to work loose. I think you will find it is a right hand thread.
