The increase in size is not that much more than stock. You may want to try to throw the stock one back on and see if it'll fit when you install the larger pulley. I run a 5% and had to switch to the K080830HD one. Unfortunately it is a very obscure size and I'll never be able to run an RPM version because they don't make it. But in your case the increase is so small, its size increase may not be a huge factor.
