hey every 1

i got problem with nc23
i lose power when sudden throttle
when i hit the throttle nice and easy everything work fine but sometimes i lose power its like it shut down when i i pull the throttle fast
just wanted to know what's the problem
i got bad air filter
or could it be something else

Sounds like you're flooding the engine when you wang the throttle open. Could be a combination of clogged air filter, clogged fuel strainer, crap in the carbs or carb jets too large.

First on the list would be to change the air filter, clean the fuel strainer (in the tap) and strip and clean the carbs.

replaced carbs with friend
my carb worked perfectly on his bike and his carb did the same thing on my bike

i will replace the air filter
but could it be the CDI ? or it got nothing to do

One other thing to check is the quality of the spark at each cylinder, you could have an HT lead breaking down or a coil failing.
