Carb cleaning
How hard is it to clean the carbs on an f3? I've let the bike sit and it has some trouble when i roll on the throttle. Throttle kills the engine but full choke will keep the idle. I think its the carbs, how difficult is it to clean them? Tried seafoam but it didn't get me anywhere, just a bunch of white smoke. haha

Cleaning them? Easy as pie. Getting them out and disassembled? A ****ing unholy nightmare. Well, the first time. I can do it now in about 45 minutes.
Follow the service manual for removing the carb unit form the engine. For disassembly and cleaning, follow this:

Yes, but it will also reduce your performance and fuel efficiency and eat up your seals. Use it maybe every 3rd or 4th fill up, about 1/3 can per full tank.

Really, the only time you need to clean the carbs is if the bike sits for a few months without fuel stabilizer in it. Fuel is clean enough these days that if you keep it flowing, you almost never have to clean the carbs.

Fact. Chevron actually puts Techron in their high-octane fuel, which is a big competitor to seafoam. BP has the best detergents, but only in the 93 octane. Shell puts nitrogen additives in ALL grades of fuel, which causes despoits to decompose and burn up in the cylinder.

Hey, I DID say clean "enough"
Trust me, deposits in the cylinder will be the least of your worries and most likely never a problem. Gunk in the carbs doesn't come from dirty fuel, it comes from old stale fuel.
BTW no one here should be using higher octane fuel unless you changed your compression ratio... Everyone should be using 87 or whatever the lowest octane is.
