They are only worth it if you hit ur rev limiter a lot. It will be harder to start though in cold weather. I dont recommend it.

The sparks timing key is well worth the money. It really helps out the throttle responce.:)

Yea that is a plus, but i ride in a lot of cold conditions so mine would never start.

The CDI makes it tough to start in the cold, but the key doesn't. I had one in mine for a while, but Sparks recommended I take it out because my quad was too heavily modded. I took it out & it does run better. If I ever switch to alky, I will probably put it back in.

I would recommend the key on a mostly stock quad, but would say to stay away from an aftermarket CDI.
