So here's the deal. I'm brand new to this site and from all the searching I have done I found this site to be the most informative. I have recently got ahold of a 1980 cx500custom and when I got it the exhaust was missing, all it had were the headers. I have mocked up about 2 1/2 feet of 1 1/2 inch exhaust pipe on either side. I am in the process of cleaning the bike up so I haven't ridden it yet but I have fired it up and ran it a bit. The left cylinder doesn't fire on idle but it will fire when I turn the throttle and after I shut the bike off the left exhaust pipe I can touch my hand to but the right side pipe is a scorcher. So I have ordered new carb kits and I am going to rebuild the carbs but while I have them apart I was curious if I was going to need to rejet them with the straight pipes with no h-box. I didn't know if anyone on this site is running straight pipes with original airbox, and if so what size jets are you running. Any help or suggestions would be greatly appreciated.
