Just finished swapping over '05 tranny to my '04 motor which the tranny lost 5th Gear... Start bike up in Neutral and it rattles and grinds at idle. I put it on the rear stand, put it in 1st and it goes through all 6 gears very smoothly but, the grinding and rattling is still present. Down shift through the gears and it's still smooth but, the grinding and rattling is still present. I have no clue what the noise could be... I figure I'm going to have to split it again... Just need insight on what I should look for????? Thanks in advance guys. Tried to do this because I didn't have the money for repair and it's my main transportation so couldn't afford the down time.
