Hey there guys, I recently picked up a ke55 and was looking to brain storm some ideas of what to do to it. i am definitely looking to respray it and put some life back into the interior, but I'm not quite sure what to do with the motor. at the the moment it has a stock 4k-C engine that i have put a 2inch exhaust on all the way to the exhaust manifold. I'm looking for extractors and a new carby but what els can i do to get the 4k running well cheers Rohan
