My 1st gear seems to whine when im coasting to a stop with the clutch not engaged (clutch lever is pulled in all the way). When clutch is engaged (clutch lever is not pulled in) it seems to still make a whining noise. When I am applying gas, the noise goes away. When I down switch to 1st gear with the clutch engaged so bike does not stall while coming to a stop, it whines. It only happens in first gear. Does anyone have any idea what it could be???? Please help....

 

Dude, all bikes and manual gear box cars make this noise...i can't tell you what it is but its normal and yes even with the clutch in

 

yeah, mine does this too. even though you have the clutch disengaged...first gear is still engaged, just not to the engine. i'm pretty sure what you are describing is normal gear whine... lonewolfcbr is right, pretty much all manual cars do it in first... even in reverse too

 

yah just reverse sounds even worse lol...

 

it is louder in revers in a car because it is not a helical cut gear. From the sound of my bike in first gear i would say it is a spur syle gear too but idk for sure as i havent been into the transmissoin yet
