Well, I made the discovery that the stock chain is endles...sheet. So what's the best way to change the front sprocket with cutting the chain? Just dialing the adjusters (at the 1/2 mark right now) all the way in and hoping there's enough slack?
That's what i did,you should be ok unless you are the only person to be replacing it with a larger one.
My only trouble was i couldn't undo the nut that holds it on so i had to go to a local dealer who had to warm it up with a blow tourch.
I went one tooth less and now it's loads better.
