I have a 86 Shadow 700, I am running straight exhaust, with a kuryakyn hypercharger and K&N hi-flow air cleaner. I've had to modify (jerry-rigged) the hypercharger to restrict the air flow, it runs great, with the exception that it runs hot between 45-65 mph. 0-45 is fine, runs at fairly normal temp, and once I get over 65 it starts to come down some. I have tried rejetting once which was unsuccessful, it made it run hotter!!! So I wll be putting the factory jets back in shortly. I'm willing to go back to the factory airbox, so is there anyone that is running a 83-87 shadow with striaght pipes?? If so, what jets are you using??? Any advice????? Help????
