HELL NO we don't break even. The guys making money are the 2-3 that chase the money around the nation and are ridiculously fast. On top of that, they have sponsorships that help them get to the point of making money. To give you some perspective, they run 112-114s at Summit.
To be competitive, yes, you will need to spend more money. Entry fees can be around the same depending on what classes you run. I spend about $400 on entry fees a weekend, but fresh tires are usually a must. I can't afford them, so I have a difficult time being competitive on very used take-offs. Suspension is also a rather required thing and is something that I dont have and many of the other "top runners" do. I'm managing a few 2nds and all top 5s this year, but I know it would be alot better if i was on competitive tires and ran race gas.
So the average race weekend for ME:
$400 - entry fees
$60 - pump gas for the bike
$30 - entry fee to the track (yes, they charge)
$100 - take offs
$20 - food

$610 total per weekend. if you want to do well in the championship you have to make it to just about every event.. there are 12, 3 of which are at Nelson, which is a 9 hour drive for us and travel expenses increase.
There are 2 solos I could run, MW being the best choice. The payout for that is usually $200. That doesnt even begin to cover the weekend.
Sunday's sprints payout contingency though, so winning, Pirelli sends $100 tire only money, Vortex sends $50 towards their products etc. It's getting to the point of being competitive enough to win that's the issue.

The guys making money are using 2-3 sets of tires a weekend, so add $1300 to that, and some race gas.. $150? and you'll see part of what their spending to make that money in the first place. They are chasing the cash that Yamaha or Suzuki pays out to Experts only for certain weekends
