Review on Tanstic Compressor Compression Motorcycle Equipment by Todd Roybal

Purchased because it included both a compression tool and lapping rods. Big mistake! I gave 2 stars because it compresses the valve spring but that's about it. This compression tool does not provide protection for the valve face. The sharp/rough edges of the supplied adapters can damage the valve surface. I used an inverted head to cover the threaded end of the rod. Also, the thread fit feels very rough, not smooth. Lapping tools are a joke. Even after thorough cleaning, they don't stick to the flat glass for more than a few seconds. I had to make alternative purchases. I was surprised to see it has a 15 star rating. Conclusion: I recommend you to look elsewhere.
