Howdy,

I recently picked up my dream bike, a 79 Magnum Xk with around 400 miles on it. Originally a PrettyBombers build I believe!

I'm gonna keep it pretty stock, but I wanted to put on a 15 bing to get a little more power out of it here at altitude (CO) - when I went to take the carb off I noticed it wasn't the stock carb, its a 1/14/157 with a round intake, and the cylinder seems to have been modded to also have a round port? (pictures attached) Any ideas what the deal is here? I assume I cant just put a rectangular 15bing intake one it... The bike has great low end but tops out around 27 and i'd like to get it to 30-35. Any suggestions on mods that will keep it fairly stock but help me with top end a bit?

Cheers!
