What to use to poke out/clear a Mikuni pilot jet ?

If the pilot jet is plugged there’s a great chance the rest of the carb is dirty. Nothing bad can come of a quality rebuild. 

I would try to cook the clogged jets in coffee machine descaler or vinegear.

I suggest soaking the jets in carb and choke cleaner spray with a top on it over night. A single carb for two cylinders should have a larger pilot jet. Could be the varnish makes it seem smaller. The wire brush strand is smaller than an E string but isn't very strong.

This is what I do.  Shame on anyone trying to clean a set of carbs if you don't already have some carb spray.    

Update and ending.
Drove the hour over to friends place this morning and to make a long story short he did indeed have fuel delivery issues which were caused by combination of dodgy petcock and sticky float and which were pretty much solved by the time I got there. Carb cleaner sprayed easily through jets and orifaces. No need to remove pilot so did not learn what size.  Bike fired up. Sounded good. Left after an hour he still had valves to adjust and fluids (oil, transmission & primary chain) to change etc.
Reminded me why I did not buy that 2nd hand Triumph 500 back in 79 

thanks all

What are you yelling at ?  We're all trying to help here.   You can get E strings down to .006,which is .1524 mm.
