Ok all ,I have a 10r and have changed like 7 front sprockets before. tonight I tried to change my friends 2005 636 front sprocket -1 tooth. it was a PAIN to get the stock sprocket off from around the chain and the back tire was full loose.
Ok i then changed it to a 14t which is -1. JT sprocket.
OK NOW........1 side is smooth and one side had an indent type thing with #'s on it. when i put it on the the numbers showing like ALL sprockets usually go..the chain seemed to pinch in and not look correct.
so i switched it back to the indent facing IN with the Flat side facing OUT.
it seemed good to go. we drove it around the block a few times. everything ok.came back adjusted the chain and he went home. NOW,
*** HE JUST called and loved the extra torque in 3rd-4th gear
BUT he says there is some whining noise now that started???
--could this be the chain too tight?
-- is the sprocket on backwards?
ANY Other advise? i do not want anything to happen to his motor or anything because of my mistake!!
please let me know
