i just got a new sprocket for my 300ex, i got a titax 15 tooth. the thing is, it wont fit with the chain on. it grinds against the case, what should i do? i would like to have the 15 toother on the instead of going down a size. i want it on their so i can hang with the 400's. i was thinking about grinding the case down about 1/16 of an inch, just a little bit. any ideas guys? thanx

Send that front sprocket back and buy a smaller rear sprocket.

Do not grind on the case. Get a smaller front sprocket that fits. If you want to go faster, go down on the rear sprocket. I think 1 tooth on the front is like 2-3 on the back.
