so after installing my new cam chain i somehow managed to fudge up how my front cam chain guide was seated or maybe my ham handed friend that was "helping" me bent it back a bit seeing how it looks like there's a good sized curve in it at the bottom(i'm waiting for my parts and flywheel puller to arrive so i haven't been able to see it yet again since this happened) but at any rate i can't find in my manual how to replace the guide. does it just 'snap' in and the old one 'snap' out of the holes the pegs are in or am i going to have to completely take the head off the cylinder? i really hope not :\
