A lot of that “lag” can be in the cvt tune. If you clutch engages at 5,000 rpm and the pipe doesn’t make power until 7,500 that you will have a dead spot that can be seen as a bog or lag of acceleration. Also the 2002-2005 Zuma have a dual angle TD slots which could also add to the laggy feel. 2008-2011 are straight groove and perform much better for a stock part. From what I can tell there is a NCY drive face and CVT with 7gram sliders. The clutch engages around 5-6k and from the side the contra spring looks red ? Never seen a red one. So basically I want lighter weights to get me to the power band of the exhaust ... basically match it ?

I bought two different Athena kits race & sport. Ran into the same question about the orange o-ring. The sport used the metal head gasket and the race used the o-ring. I ended up using no base gaskets in order to get my squish to spec. with the sport kit.

Does it dry up like glue because putting it on it felt sketchy

Too funny I did the same thing ended up removing and redoing with Yamabond

Just use the cooper spray on the head and possibly if you use any of the base gaskets.

Too funny I did the same thing ended up removing and redoing with Yamabond I feel like I need to. I guess I’m use to a seal being tacky , this seemed like wet spray paint. I do know it sticks because there wa stuff stuck to the bottom of my shoe with that spray.

I hung it from a wire sprayed both sides and let it dry for 3-5 minutes.

I don’t prefer the copper spray for gaskets. I use a 3 bond product but ultra grey would do the job it’s tacky and dries firm. Weights and TD spring set your rpm, stiffer clutch springs help bypass the bog. Experiment and see where the pipe makes power with heavy weights. That will tell you where your clutch engagement should be. A heavy contra spring forces a downshift for corners, raises your cruise rpm and accelerates belt wear. Too heavy weights slow acceleration, too light you make a bunch of noise and don’t go anywhere. Stiffer spring rpm increases unless you raise the roller weight, lighter spring decreases rpm unless you decrease weight.

Problem is I don’t know what was installed in the clutch by the previous owner. All I know is my power is at 7500 rpm

Your best bet is to check what is installed so your not playing the guessing game.
