Dynojet thunderslide kit?!?!?!

I'm looking to upgrade my 80" evo (98 RK).

I keep reading about installing a Dynojet Thunderslide kit with the Andrews 27 cam. My question is which Kit? There's a stage 1 or a stage 7??
Engine is currently "stock" with 33" fishtails and BCT baffles and an open SE air filter.

Any help is appriciated...

The Stage I kit will give you more torque, as the slide actually masks part of the bore of the carb, when it is all the way up.

Before I'd spend the money on a ThunderSlide kit, I'd consider a Mikuni 42 carb replacement first. ( Particularly if it's torque you seek!)

A bone-stock CV will out-torque a 42 Mik, and the Stage I T/Slide will run more torque than the un-touched CV.
The Mikuni will show more in the upper rpms.
We did back/back testing CV vs Mikuni years ago.
Both are very good carbs.

Check out the Yost kit which IMHO is a better upgrade. Stick with the CV as Scott has suggested; you could add a few $$ to the cost of a Mikuni and have a street port job done.
