As I do every Spring I set out to get my dwindling fleet of motorcycles running for the season. As a general rule my 70 tr6r has always been the most reliable bike I have owned. I got it running last week, rode it around town a bit and parked it. Took it out a couple days ago and about a mile from home it started running erratically sputtering, wanting to die. I had to keep throttling it up to keep it going. I got it home and yesterday went out to see if I could figure out what was wrong. Had spark and gas, but it seems to want to abruptly die at 1000-1100rpm's. This is a guess by sound since the tach and speedo haven't worked for a decade. So to keep the thing running I have to keep it idling at 1200+ which is way too high. I have had the carb on and off the bike four times totally dismantled and meticulously cleaned. I have access to the pilot jet from both sides and have used a guitar string to make sure the pilot is clear. I have blown air, carb cleaner and gas through every opening in the carb I can, but it still runs the same. If I mess with the air mixture it does react by 1/4 turns, but it has always been set at 1-1/4 turns out and run fantastic. The slide has a sleeve and is one season old. New needle one season ago. Nothing has changed on the bike since I rode it last fall. I know it has to be something silly simple, but it eludes me. As many ideas as I can hear the better and thanks in advance.
