One of NASCAR's biggest names says these are the reasons he might drop his team

Kyle Busch is already unhappy about rule changes that limit the number of lower series races Cup drivers can run in a season.

With Brad Keselowski's recent announcement that he was dropping his truck team, Busch becomes to only NASCAR driver to own a truck team. He's already said he might drop it because of the new rules, but now, his team has told Jalopnik the specific reasons he'd let the team go.

"I race in the Truck Series because I love to race, but it is also a business," Busch said in statement. "Being able to bring in sponsorship for the races that I drive helps subsidize the costs for our other teams in the building based on economies of scale.

 "We are not going to comment on the amount of personal money I contribute, but just by saying that tells you that we operate at a loss. Too big of a loss or not having enough fun would make KBM seriously consider the alternative."
Clearly, Busch operates the truck team at a loss -- the reason Keselowski dropped his squad. The financial aspect makes the Busch team's future even more suspect, given his recent remarks.

In an interview on SiriusXM Radio -- and reported on -- Busch slammed NASCAR's new rule that limits the number of races Cup drivers can participate in, in lower divisions.

Under the new rules, drivers with five or more years of full-time experience can run in a maximum of five races in the Camping World Truck Series, and seven races in the NASCAR Xfinity Series. Here's what Busch said:

But if we keep continuing to put the limits on it, I'm going to tell you right now, if the limits to the Truck Series go to zero, I'm done. So you wouldn't see Kyle Busch Motorsports teams out on the race track.

His concerns center around losing sponsorship, but also losing the enthusiasm he has for truck races.

I enjoy going out and running Truck races and if I'm not allowed to do that, then why am I owning a team that I'm not allowed to race for? It just doesn't make any sense. If I'm out there spending money for other drivers and whatnot to come up through the ranks, but yet, I'm getting beat up as not allowed to drive in it and it's no fun for me, then why am I spending my money to continue to evolve talent that's going to replace me one day.

This is an issue that doesn't only impact Busch, and it will be interesting to see how other drivers respond.
