Read and you will learn

Does the job. People are complaining about it not fitting in their exhausts but if they read the notes they would see that they may need to trim it.

“Notes: Check measurements before ordering; will not fit exhaust outlets smaller than 3/4". Trimming may be required for fit with 2-stroke exhausts.”

Great for many different bikes

I like this plug because it fits a wide range of bikes including both 2 stroke and 4 stroke. These have a very good fit in most bikes, including ones still equipped with a stock exhaust system.

Does what it's suppose to.

It works like it's made to. The remove before flight tag is not made well and if you plan on leaving it in while driving to the track it will be gone before you get there like mine was lol it was the first time using it but still gets 5 stars because it does what it's made to do.

For the idiots

It’s for a four stroke not a two stroke but it should still say (ONLY FOR FOUR STROKES)
