Much of the knowledge you need about karting is only found from talking to other karters. The good thing is that karters in general are very willing to share what ever they know about karting with new karters.
As far as purchasing a used kart, some of the best deals on used karts are right here on this web site. A quality used kart can save you several thousand over a new package. On the other hand, a cheap beat up used kart is no bargin as many of the componets will need to be replaced. For example, a tired brake system can be expensive to replace as you just about have to buy all new componets as often times they are not rebuildable. Kart brakes tend to wear out after a couple of years of use. Ask any older Tony kart owner what brake parts cost! If the frame tubes are excessively flat spotted, the chassie is junk no matter what the price. A $4,000 used kart can be a much better deal than a $2,000 used kart depending on the condition. New karts can range from $4,000 to $6,000. Yet the $6,000 kart maybe the better deal once you look at the quality of the componets and the dealer’s service. The bottom line is that you can’t talk to enough racers or look at enough karts.
The main thing you have to determine is which Tag engine is right for you. The first thing I would do is answer two questions, what is your weight and where do you intend to race?
Your weight will in part determine which engines you should look at. For example, if you are 175# or under (195# if you are a 35+ age driver), you won’t want to look at any of the high weight engines such as Sonic. You would have to add too much lead to the kart to make minimum weight. On the other hand, if you are 210#, then the light weight engines like Rotax or Leopard are out as you will be way over weight for your class.
The second part on where you race is also a major factor. Since the engines are so different in performance characteristics, some are better at certain tracks than others.
Other factors to consider is how much do you wish to spend and what is your mechanical skill level. Some packages require more maintenance than others. The Rotax is king in the low cost to maintain department, along with the Biland. The high winders are higher maintenance engines. If you can do the work yourself, then it may not be as big an issue than if you need a shop to the do the work.
