Growing up in Camas, Wash., NASCAR driver Greg Biffle always loved tinkering.

When he was about 8 years old, Biffle noticed the family lawnmower wasn't working. Biffle took it apart and put it back together. Almost.

"I messed up the throttle spring. That was the only thing. I had it backwards," said Biffle, who has been racing in Sprint Cup for 11 years and is heading to Pocono this weekend. "Outside of that, it was working great. I just love fixing things."

Well, now that he's 42 and leading the NASCAR points standings this season with one victory and seven top-5s, he has no time to work on anything.

He did finish restoring a 1962 flat-bottom boat but he has a 1965 El Camino sitting in a corner in his Washington shop. He has several off-road vehicles and some dirt bikes. All needing fixing.

And he has a 1970s Montesa motorcycle that his father owned.

"That bike is special to me. It was my dad's last motorcycle and the one we had ridden together," Biffle said. "I've always wanted to restore it. I just don't know where to find the parts and find the time to fix it."

So Biffle turned to Rick Dale, host of the History channel reality show "American Restoration." The big reveal of whether the bike was restored is Wednesday's show at 10 p.m. ET.

The show, a spinoff of "Pawn Stars," chronicles Dale and his Las Vegas team restoring various vintage items. They spent some time working on Biffle's Montesa.

"It was fortunate that I've done a lot of bikes. My dad gave me my first bike at 13, and he told me to fix it. And I did," said Dale, whose shop has restored more than 70,000 items in the past 30 years. "For Greg to bring a piece of his past, it was a huge amount of pressure. Everything has to be perfect. People who own items want them to be great."

Biffle said he is a fan of the show and thought it would be perfect for his bike.

"I see myself in Rick. I had a lot of fun doing the episode," Biffle said. "The bike has some history for me, and I wanted to see care put into it."

Viewers will need to watch the episode tonight to see whether the bike was restored.

"Our goal is to always bring back memories you have with an object," Dale said. "It's like it's dead and we're trying to bring it back to life. The satisfaction is the look in their face when we accomplish it."
