In 99 Cat upgraded the triples to the ZRT2 chasis aka AWS5 suspension. This also came with a more resitrictive airbox and exhaust, which is likely the cause for the power loss, along with poor setup from the factory.

The jetting (rich) and clutching weren't that great from the factory. You can remove the internals of the airbox and D&D has a different lid for the airbox to flow more air.
