Review on HTTMT- Gun Black Engine/Transmission Bolt Cover Cap For 2000-2006 Harley Softail Twin Cam [P/N: MT247-004] by Dmitriy Kingsley

I read that this product had poor reviews due to cracking or melting due to engine overheating. I cracked 4 smaller caps when I put them on. Then I got smart and used a 3/8" long bolt with a piece of air duct on the bottom. By applying steady pressure or force with a small rubber mallet you can do this without breaking the caps that cover the motor bolts I have applied silicone to the inside of the caps. This way the silicone acts as an insulator and the caps should not deform from excessive heat. Always use silicone when putting on caps. Take your time and everything should be fine. It is not that expensive and I didn't use everything they give you they will have extra caps.
