The stuff is called Yamaha Carb Cleaner.
The Part Number is ACC-CARBC-LE-NR
For lightly gummed
up carbs, use per the bottle instructions.
For really gummed up carbs, where they are going to have to come
apart,
mix the carb cleaner 50/50 with water, put the carbs-or parts-in
a can,
cover them with the mixture, and heat it to an "almost" boil
- surface
should be barely rolling. Let them cook for approx. 15 minutes, then
rinse the parts in fresh running water, and blow dry with compressed
air. Check the bodies and bowls to make sure all the small passages
are
clear, and soak them a bit longer if they aren't.
Specific comments and cautions:
1. Do this outdoors, or in a VERY well ventilated area - the fumes
are
pretty rough..(cough, hack..)
2. The cleaner will not harm rubber parts-unless they've already
started
deteriorating. It WILL quite cheerfully remove paint from painted
parts,
like black GPz Kaw carb bodies. Brass parts left in too long-or at
too
high a temp-will discolor.
3. The stuff is reusable and pretty long-lasting. After it cools
down,
pour it into a jug and cap it - it will evaporate very quickly if
left
in an open container. Every once in a while strain it thru a paint
filter to get the grunge out.
4. I've got a collection of cans and containers of various sizes
to use,
all the way from a tuna tin which is handy for small parts, up to
a pan
that looks like a large mud pan for drywall work, which will hold
an
entire rack of carbs for an inline four. Heat comes from a double-burner
hot plate, picked up in a yard sale for a few bucks.
5. Wear rubber
gloves. This stuff will pull the oils out of one's skin in no time.
Hope this helps!
