This plug really does its job.
JEFF in CA
Simple to install. Bulletproof. Gives me a easy to read tachometer and shows the highest rpm after you shut it off. Both excellent tuning tools. Just an excellent product.

Gotta have these if you have air forks unless you want to take the bars off before every ride and in between motos.
Oliver in FL
A little pricey but it looks cool and does what it's supposed to.
