I rebuilt my engine a while back and I can't remember if it was a 11:1 or a 10:1 is there any way to find out what piston I put in the motor? And what kind of muffler would be best for my bike? Thanks

if you calculate your volume at top dead center and compare it to your volume at bottom dead center that will give you your compression ratio...
ex. if you had a 410cc's at bottom dead center and had 37.2cc's at top then you would have an 11:1 compression ratio. you could test the compression with a guage but you can not accuratly calculate the compression this way because it will change with different cams...
