Re: Honda CB500T Problem

Hello all and thanks in advance for any help you can provide. I have a
Honda CB 500T. I have changed the plugs and points and the bike runs pretty
good for a day. The plugs start to foul after that. I think it is an
electrical problem. The carbs have been redone recently. Any ideas what
may be wrong?

Yep, it's running too rich, it is not an electrical problem.

I have no idea what sort of carbs you've got so my advice
is generic, but you can't assume the pervious owner didn't
mess with things.

Take the carbs off and check:

Float level, if the fuel level is too high it will make the
mixture rich.
Main jet size, if not stock, replace with stock size.
Pilot jet size, if not stock, replace with stock size.
Needle jet clip position, if applicable.
Float needles and seats for wear.
Look for missing rubber plugs inside the bowls, if any.

Also look for rust or sediment in the float bowls, if you've
got rust it's time to flush the tank and at a minimum install
a fine mesh filter, at worst you will have to have the tank
acid etched and sealed. POR-15, KBS, and Kreem kits will
all work fine IF YOU CAN FOLLOW DIRECTIONS.
