    Braided Oil Line Kit for 98 FLSTC

    A little tricky at first to figure out without instructions but after a little tinkering they installed almost flawlessly. Had to machine the oil pump input fitting to fit, hit the side of the pump casing when installing.

    Cobra oil dipstick

    Great looking on the bike. Difficult to see oil level on it.

    Great Deal

    2008 FZ1- Fit perfectly, no 'big glob of glue' on the end holding the magnet in. Nice black finish, we'll see if it holds up. Same exact length as stock. I'm actually kind of excited to see what it pulls out of the oil at the next interval. Cheap insurance, money well spent!

    Waste of money!

    Bought this to make it easier to check the oil. Followed instructions precisely. Problem is the cap is poorly manufactured for an exact fit. The lip that is supposed to catch and lock the cap to the base does not fit. So the cap just sits on top of the base and pops right off as soon as the engine is started. Total waste of time, money and energy. This is the second Kuryakyn product that has been a major disappointment. I am going to consider that before buying anything more from them!
