I modified my TAPP secondary. Modifying the stock secondary will be a different process. I believe Cornell Customs can modify a stock clutch for a larger belt. KWI's secondary can accept a larger belt with the correct deflection.

Just installed this big boy!

It works great. The belt has very little deflection. The belt rides higher now and the sheaves are not touching when its closed with a evo badA belt. The Evo belt is a Worlds Best belt. WWB0047 part number. This helps the jerky slow start i was getting with a loose fitted belt. The gear...

Not very exciting, but I took .30 thousandths off the inner base of my Tapp secondary sheaves today. This allows the clutch to close together more. Now the longer gboost belts will have correct deflection and increase gear reduction on take off.

Dang, that's slick!

What is the belt deflection with the Pro R belt on the Kwi secondary?

Just a update on the new inner sheave.. its working good at keeping the temperature in check. I can push the h2 as hard as i want now. Im having no problems at all. Worth the upgrade.

Another thing to consider, is the sheave diameter is much larger. I first thought I had the wrong sheave, but realized the bigger sheave has bigger fan blades.. its as big as you can get without hitting the inner housing. The belt just doesn't ride to the top. I can say it moves alot of air now...

Tapp has been very responsive through email. I purchased the primary and secondary through Evolution Powersports. Yes I was charged for the sheave. I would expect Evo to get there arms around these sheave swaps for customers soon. Not everyone will be willing to change these out themselves, nor...

Yes, I got the sheave from Tapp. Holder and spider wrench from Evo.

Oh yeah, and a extra spider nut.. like $15 bucks

Its not to bad.. 30 min tops. Evo sells the tool needed to hold and disassemble.. You will need a torque wrench up to 130 ft lbs. One big socket 1 9/16. And a torch. And of course loctite.

RCOR sells a roll over valve. Its a two way valve. It allows air in and out. I dont think the H2 has a way to vent, so this fixes the high pressure problem. It stops fuel in a roll over. Krx has same issue.
