A custom motorcycle builder from Michigan will give a chopper to the Crazy Horse Memorial Foundation on Tuesday for its fundraising efforts.

Eric Gorges of Voodoo Choppers also added a Crazy Horse theme to the bike's paint job.

The 3:45 p.m. presentation at the Crazy Horse visitor complex will be marked with a blast removing 2,450 tons from the mountain carving depicting Lakota leader Crazy Horse.

Ruth Ziolkowski, chief executive officer, said the foundation will draw the bike's winner Sept. 10, 2010, on what would have been sculptor Korczak Ziolkowski's 102nd birthday.
