All of our kits use a catch-can or a filter. For most, the filter will hold the gunk in it for 3000-5000 miles, at which point it should be cleaned out to allow it to accumulate for another 3k-5k miles.
The benefits, even to a casual rider, are numerous, as listed above in post #4 and explained in more detail at this
LINK, which also has charts showing the power benefit, for those interested in more power.
By using an EBS, just that, will result in a Stable tune, which most (even the average rider) will Not experience, sans an EBS.
The interesting thing we have discovered over the years is that there is usually no One modification that produces a Big result. It is usually a synergy of many smaller mods that result in significant improvement.
Almost without exception, our
Performance Plus Stage I Upgrades will have a Harley producing more power than other Harley's that have had a typical Stage I AND Stage II upgrade. This is because we pay attention to all the little things...and those little things add up to a big benefit.
Nice Side Benefit: Our Performance Plus Stage I Kit usually cost less than a Typical Stage I kit, and Far Less than the typical Stage II upgrade.
