Tusk Billet Bling Kit
Andrew in TX
Rear master cylinder cap is taller than stock
Other than the the kit seems like a good deal. I have not rode the bike yet, still putting it together. If i have any issues I will update. I recommend it this is going on a bike that is not newer to go ahead and get new seals for these parts when you install the master cylinder covers.
