I recently purchased this minibike to modify and use in the snow. Now I wouldn't feel right if I did any type of modifications to it. Mac and Harleys identified it as a Cheyenne Warrior model 400 that was made in L.A., maybe 1960's. I don't like to alter vintage bikes and this is a really cool looking bike and very well made! Since I got it home: took off the Briggs motor and removed the goofy foot pegs that were added over the original mounts, removed the extra rear sprocket, (original worn out) and it seems to be a solid bike besides the scrub brake arm that was added on over the original one, and the seat is also not original. What do you think I should do, sell or modify. Thanks, Owen.
