Im having to replace my sprockets. I removed the back wheel and now im trying to take the front sprocket off. I put the bike in gear and when i try and remove the bolt, the sprocket just wants to spin. am i doing something wrong. Is there a trick to this?
Thanks

Impact gun.... If you dont have one................ The engine compression it not high enough to allow you to loosen the nut... Try it in Neutral with the chain on and use the rear tire to stop the sprocket from spinning... Make sure you straighen the locking tabs on the sprocket nut also

i just have changed it yesterday,,it was fairly easy , definitely need to lock the rear wheel to stop the sprocket from spinning...i have installed a AFAM 15tooth sprocket,,,noticed a pretty good change in acceleration ,especially on 2nd gear..there is a little bit of extra whining going on right now,,i made sure to line the rear tire up nicely,,,i dont know maybe it will dissappear in time,,,nothing major anyways....

i will ride it with my gps to see what kind of difference it made to the actual speed vs indicated...

Put it in neutral. If it rotates in gear that may damage the tranny. Trick is to loosen the rear axle and chain adjusters. Push the wheel forward. Remove the sprocket nut.

Did you use a impact gun? How did you lock up the back tire? When i made the first post, I already had the rear tire off. I put it back on and tried again. But the bike would move when i tried to take the front sprocket off. So im going to do like Admin replied with and get a impact gun.
Thanks

i didnt use an impact gun but im sure it will be more effective....i actually had someone sit on the back seat while i unscrewed the nut,,,so with 2 people it was easy

Stick a 2x4 through the wheel to lock the rear.
