How often should we be cleaning out carbs?

If the bike is ridden at least every couple of weeks, one might be able to go for many, many years without cleaning out the carbs. If a bike isn't ridden for a couple months, or otherwise winterized, a 6 month old bike might need a thorough carb cleaning to get it running well again.

I see. Thanks for the clarification Alex! :thumbup:

Put some Berryman's B12 Chemtool through your gas every 3-4 tankfuls (1 oz./gal gas) and they will stay clean.

Alex, I treat my fuel with Sta-Bil Marine--the blue stuff. I make sure it is run through the system before I store for the winter. I take a hemostat and pinch off the vacuum hose to the fuel petcock. This allows me to run the carbs dry. The tank gets filled to the top. Every four weeks, the tank gets drained with a siphon pump and the fuel is put in the cage. I put fresh fuel into the tank that is treated with Sta-Bil Marine. I have had no problem firing up the bike in the spring. The garage/shop I keep the bike in is heated and never gets below 50F. The shelf life of the new weasel piss enriched fuels have a very short life. They absolutely raise hell in two-stroke applications. My three HP Yamaha Outboard Motor has been a royal pain since this new fuel was introduced. I am seriously considering buying a four stroke outboard for our dinghy.

I'm in California. I don't do anything. :) Other than make sure to take the ninjette out for a ride at least every few weeks...

Alex, My daughter lives out your way in San Jose. She just loves it there--the weather, the people, the whole thing. I am very glad she is happy--just wish it was not so far away.

Lots of carb info in the Intake section here - https://faq.ninja250.org/wiki/Ninja250_Howto

If the bike is going to sit, adding a fuel stabilizer and filling the tank is a real good idea. Ethanol-free gas is best if available.

Draining the floatbowls is also smart. The fuel that sits there loses it volatility, and will make it hard to start. When restarting after draining, you will need to crank a bit to get vacuum to open the petcock, so make sure the battery is good and fully charged.
