Recently bought the above. It sat for 17 years, but ran when put away.. It has 3000 miles on it. It will only idle when the choke is on. If I back off on the choke it will stop. or if I try to use the throttle it will stop.
I have done the following to get to this point.
removed and clean the gas tank. replaced the battery, fuel filter and fuel pump relay. tested the fuel pump ( it works)
I have not removed the carbs and was hoping I don't have to. I have used Barrymans B12 chemtool in gas ( no Help). I did spray carb cleaner air intake and I could use the throttle and the engine ran only when I kept spraying the cleaner.
Any help or answers would be appreciated

 

welcome to the forum. You may have to do what you don't want to do. Most bikes when sitting for a long time gas tends to coke up the carb. overhaul of the carb should fix your problem.

 

Carb issues.

 

Thanks for the help. I did end up rebuilding the carbs. The engine now runs fine. However my next problem is the slave clutch.
I remove the slave clutch. It was frozen and gunk up. I cleaned replace seals and spring and it seems to be fine. I reinstalled bled line, but know matter how much I bleed I cannot get any pressure with the clutch lever. I can shift gears without using the clutch. What am I doing wrong???

 

Are you sure the master is good and free of air?

 

I recently rebuilt the master cylinder. Have bled the line to the rebuilt slave cylinder, but still cant get pressure so the slave cylinder works. I don't know where to go from hear.

 

Is the master pumping?

 

When I block the outlet , It seems to have pressure. but not much.

 

Did you bench bleed the master?

 

How do you do that?
