Question for Yamaha Racers

I read Jim's comment saying the bodywork provides no advantage... but on the seat subject...Lee says there is no seat advantage, yet John says below that there is. I am too new to karting to know, but at the end of the day would prefer to just get a bunch of people on the track to hack around and race. If there is an advantage then we should keep to WKA rules so the rest of us don't have to either buy a new seat or drive with a disadvantage. If not, then it doesn't really matter if you're only going to race here. Does this seat/bodywork apply to just the jr KT class that lee is talking about, or all KT classes?

Brian,
Here is the low down on seats and their effects on the handling of the kart
1. Stiffness/Flex of the seat
2. Raising or lowering the seat.
3. Laying the back of the seat down (lowering center of gravity)

This is why the largest and most popular seat manufacturer makes many versions of seats, that have different construction, stiffness/flex and layback. Depending on the flex of your chassis, your size, track conditions, etc. will determine what is the best seat. Fact, a seat is a huge tuning device.

The advantage of the 4 cycle seat is really for heavier and or taller guys, because they are designed to lower the center of gravity. If you are lighter and shorter, this can have an ill effect on the kart because it might not properly transfer the weight.

I hope this helps everyone.

I asked everyone for their opinions so we can make a decision in what is the best interest to grow the class and the current participants.

I’m also new in Karting but I did not see any grow in our class due to the fact GSKA allowing the seat and body from 4 stroke cycle classes to compete with us.
But the point is that allowing the body is not a great help for then to come to our classes because they need to change the wheels and tires and that cost more than the body, or the next question will be if they can use the 4 stroke class tires to compete in 2 stroke?
Why not to leave everything the way it always was?
If you want to race 2 cycle put one together for that rules or if you want to run 4 cycle get one for that rules (I planning to race also 4 cycle and putting all together by the 4 stroke class rules)

ok if I am 180lbs, is it best to stick with the regular seat? Any ideas on where the lines are between seats?

I vote for WKA rules all the way, if not then we are NOT really racing under WKA rules. It's that easy, if you guy's want to make up your own rules then call them GSKA rules. But it's one or the other.

How many more KT's can we get running do you think? There are a bunch of blueprinted KT's engines on EKN recently for sale. Hopefully this will build the class!

That is a good question. As you may know we will be having a booth at the Auto Show. It will be important to have someones KT100 at the show so we can show it and talk about it.

A lot of it depends on the economy this year.
