1980 cb400t mac 2 into 1 jetting
« on: May 10, 2014, 23:22:23 »
I've got a 1980 cb400t that I've been working on. I put the MAC 2into1 complete exhaust on and i am in the process of tuning the carbs. Almost have it done, I just need to know what you guys would recommend. Right now its got a 75 pilot and 110 main. I first tried backing out the air/fuel mixture screw, but thats not getting it rich enough. The pipes right out of the head are getting way hotter than i expected. Ive already scorched the pipes, they got red hot. Any suggestions?...
