Customer Reviews

Money well spent!

By David C. on  Verified Purchaser

I was pretty skeptical about spending over $250 for a dipstick, but I am amazed at the improvement it made in my engine's performance. It is easy to feel the improvement in throttle response and the engine just seems so much free-er and happier, not to mention the elimination of oil from the air filter blowing all over the rear pipe. Money well spent.

Must Have

By Steve H. on  Verified Purchaser

This is a must addition to any built M8 motor. Instantly solved the oil blow by problem. Easy to install and looks great!

Issues were corrected quickly

By Bud on  Verified Purchaser

The vented dipstick was as described, seems a bit pricey and the wrong one for my bike was sent but they were very responsive and corrected the problem quickly. Overall satisfied
