 Daft question, I am in the process of rebuilding and giving my carbs  a good clean on my CB 400F, could any one tell me if on the pilot jets there is a hole which goes straight through, end to end. I have owned this bike for over 25 years and has been off the road for a couple of years so is in need of cleaning, any tips would be appreciated

The pilot jets have a very small orifice & great care should be taken in trying to clean them out using just carb cleaner & compressed air initially.

i had a problem with my 550, the pilot jets were completely blocked and refused to be cleaned.in the end i got some new ones, but had to order from Canada ! They dont like being left unused,if yours has been running they should clean ok.

randka:
thanks for the replies, I have rebuilt the carbs and have put two back together, I had a feeling there might be a hole through them, they are blocked then I will have to have another look , like you say I may have to buy some new ones

My CB400F carbs were all gummed to hell, had the same problem with a 1990 CBR600 I've just restored which had been standing for 6 years?







Soaked the jets in new petrol, tried 3 different sorts of carb cleaner to no avail... in the end the only thing which worked was holding the jet and blowtorching them.  ;D

The gummy gak burns up and turns to ash, easily teased out...
