turbowrenchhead Posted June 5, 2013 Report Share Posted June 5, 2013 I had a lean run away after throttle return one time so I had to kill the ignition to shut it off. Flicking the throttle didn't work. I was able to drive it after a few adjustments however I had to slide my thumb off the throttle to snap it back, then the idle would return to normal and allow me to shift or brake easier if I did that every time. I also lost probably 20~30 ounces of coolant. I did a pressure test and no external leaks and it held pressure. I ran a leak down test and it held 7 pds for a 1/2 hour before I pulled the tester off.The plugs looked too rich so I dropped the 350's to 340's. I pulled the head and I found one of the dome o rings did not look the best. There were imperfections in it. I cleaned it all up and replaced the o rings. Re ran the leak down and it passed again.The o ring must of only been leaking when it had the most load on it and pushed coolant out. I tried to get it into 6th a few times. It wouldn't pull in 6th gear in the dirt. I would barely on pavement. This is with a 15 front, 40 rear and 22" tires. I'm debating on what size to go to in the front. I have a 12 front sitting on the bench. We had to ride in hard rain for well over and hour. Plus some earlier that day. There were several large puddles that I had to go through. So it wasn't a surprise when I found dirt inside the uni filters and the intake tubes of the cfm. I cleaned it all out and cleaned the oiled the filters. Would K&N's protect better against dirt intrusion? Now I need to find a more durable exhaust joint. The $40 set I bought off of ebay didn't last an hour. I'm thinking intercooler hose and some heavy duty hose clamps. I'll have to make my way to a truck shop sometime this week. Quote Link to comment Share on other sites More sharing options...
turbowrenchhead Posted June 6, 2013 Author Report Share Posted June 6, 2013 I found some silicone hose locally yesterday. I also went back through the carbs and stripped them down and blew out all the passages. I fired it up and let it warm up and took it down my street for a couple hundred feet up to 3rd gear. The lean runaway didn't come back but it didn't run long. Quote Link to comment Share on other sites More sharing options...
