OK, I know clutching gets a lot of discussion on here but I can't quite seem to put it all together. Has anyone found a combination of tweets to get low end grunt without sacrificing the top end? I'm thinking about 24g weights (30x18mm right?), clocking one more position, I have an intake mod with a UNI filter, but if I add the ejk and exhaust, would I loose a lot of top end? What if I did all mentioned above and went to a 28 or 29 tire? I've done the math for trucks I've built, gearing vs tires but this is a lot different.  At the end of it all I'd like 28" mongrels but want more low end grunt without sacrificing the top end. Thanks.

The short answer is you cant have it all.  Unlike trucks we are limited more by the HP we have.  If you go to 28's you will lose top end.

I am pretty sure a ZForce 800 with the race kit and 28" tire will walk over a stock 800 on 26".
With the secondary at B2 and the race kit I hit the rev limiter each time on top

On mine i plan to put some 27", not more because I don't think the 28" clear the 2 brothers exhaust.

Agreed. With only 65 hp or so there isn't a lot of wiggle room. Sometimes you have to rob from Peter to pay Paul...

OK so what will effects of lighter clutch weights be? Will I get better throttle response or is even worth changing them? Ivery watched your videos online about clutch clocking and that's my current option 1. But I guess I don't fully understand the effects of the weights.

I looked into the race kit, but it's not really an option here in states. I've also read about about issues with the dry clutch. I can get the exhaust and the tuner but can't find a dry clutch kit.

The weights decide at what RPM the CVT does it's "gearing". By changing the weight, you are trying to find that sweet spot where the engine makes the best power. the lighter the weight, the more RPMs it takes to push the primary closed. Google apex clutch, there is a good write up on how it all works and you might get an idea on where you might want to go next.

ZForce800, what have you read about issue with the wet clutch delete
For me i have only see real gain everywhere.
- 6-7 lbs less rotation mass make the engine way more responsive.
- better engine braking
- stronger design
- You can use any oil
- better engagement

If i have only one mod to do, it will be the wet clutch delete. The power is NOW, the rear wheels are connected with the gas pedal.

Polaris and Can Am dont have wet clutch and it's the first mod for the Wildcat 1000
