Review on HTT Black Bolts Toppers Harley by Matthew Hall

The only difference between these caps and the Hot Toppers caps is that the fit is not as straight. But that's not so important when you have a drop of silicone. The difference in price earned them four stars in my book. One complaint I have with both brands is that they will melt and warp at high temperatures, such as with B. Rocker arm bolts, exhaust port bolts or top engine mounting bolts. The more heat, the faster they melt. Also, I'm not thrilled with the importance they all have. It would be much better to make them smoothly curved.
