FLOAT NEEDLE VALVE

Post by OTTERCOMET » Thu Mar 29, 2018 12:10 pm



Rebuilding the carbs on an 82 Interstate, using Randak's kit. Got everything apart and cleaned and all channels cleared but having a problem with the needle valve plungers - can't free them up - 3 of the 4 plungers appear to be in the extended position while 1 is compressed. I have tried boiling, soaking in carb cleaner, spraying with Blaster penetrating oil - nothing works.
So, I'm looking for a) another idea on how to free these plungers or b) a source for replacement valves and seats - local MC parts folks look at me like I'm nuts when I ask if they can supply replacement valves and seats for this vintage of bike. Does anyone know if there is a cross reference for the same part from a more current bike - these things do not look like they would be unique to the Interstate or should I say Keihn carbs.

all you should really need is the float needle. When they are stuck like that you should always replace them. Use a Q-tip for cleaning the sealing area were the needle tip will sit in. Float needles can be bought off e-bay or any motorcycle shop part number will be K/L 18-8955 they normally are sold in a bag of six.

There have been a multitude of negative reports on after market float valves not sealing properly. OEM valves are recommended and are still available.

Ditto, I have sen a lot of cases of aftermarket valves not working, very few cases when they actually did the job.

Thanks for the input.
I have managed to free up the plunger on one of the needle valves by alternately freezing and then dropping into a glass of boiling water. It is now back in the carb cleaner for some lubrication and I am proceeding with the other 3 valves to see if I can get the same science to free them up.

pistons on all 4 valves have been freed up using the same process.
