Carb rebuild
Laverdaroo:
I have a sonic cleaner if you're stuck, bung em down to me and I'll fettle them for you. I've nowt on at the min as waiting for the frame to come back so twiddling me thumbs...........all three of em ;D
Offers there if it helps.
Multiman:
Very kind offer Laverdaroo.
I need to get the things off and apart which given my job list I have been given may take some time.
But once there I'll get back to you.
Cheers
Tim
Sesman:
Just a word of caution, but be aware that ultrasonic cleaning is effective, but not the panacea of carb cleaning. I’m sure you probably know that but thought it worth mentioning. The problem children are the pilot jet drillings, which pass from float bowl to Venturi via the pilot air screw. Get yourself a can of quality carb cleaning fluid (I recommend STP) and work round the jets, being careful to systematically close them off to force fluid through the passageways. You might need a couple of cans to give them a good going over.
Oh, and look out for the spiders in the pilot jets😀
Multiman:
Thanks Sesman for highlighting these issues. I will invest in even more carb cleaner.
I'm sure once I've got them off and apart the drillings will become clearer, but what is the Keihin carb model number to see if I can find any more info online like a schematic.
Many thanks
Tim
Sesman:
Now that’s a really good question that I can’t answer. I’m sure a 400/4 owner/former owner will be along shortly to answer that one.
