Yes theres a fuel filter.
doubt its the plugs.
you dont need octane booster or even anything above 89 octane.
chances are you have a problem with the ignition coil(s).

Bike runs good but when I give it full throttle, especially in 2nd gear, it cuts out and almost stalls. Do you have any suggestions?

Could be starving for fuel or could be the coil. Is it fuel injected or carburetor ? Now when it cuts out this is the important part. When it cuts out is it a jerky quick cut out or a much smoother and longer cut out. The quicker one represents the coil and the longer one would be fuel. If it has a carburetor then check the fuel line. Is it old and stiff or shows crack lines? Check the fuel filter. if it is fuel injected then the fuel pump could be at fault. You know there are also other things to check. The spark plugs can cause it to cut out under a load. The spark plugs should be the proper ones for this bike. Each plug has a rating and you have heard of being a hotter plug? This just means more or less spark power at the gap. Too much is not as good as too little. But it should be enough to ignite the gas. You can remove the plug and inspect for cleanliness and color. a brownish color is best. White is not good and means it is too lean. Black and it means it is not burning correctly and oily. When you have the plug out ground the threads to the engine and turn your bike over. What does the spark look like? Dark blue is good. Red is ok, light red with a yellowish tint is getting weak and will not be enough to fire the gas at a higher speed. what happens is the faster the speed of the bike the quicker the spark has to develop. If it is a lighter color and it has to fire quickly, the spark would have almost diminished to nothing, but on the other hand if it is dark blue if it has to fire quickly there is still enough uumph to do the job. You see the amount of spark is also determined by the frequency the coil on and off. Well hope this helps you to determine if it is gas or spark problem. If spark its the spark plug,coil or spark plug cable. I have seen the cable where it contacts the spark plug be a problem.
If it is fuel , fuel filter, fuel line,fuel pump, injectors and possibly which I have overlooked, could be other electrical items such as throttle sensor, cam sensor. Not sure what bike you have but this should cover most all of it.

07 blade cut out on road after refuelling

Check that fuel is getting to the cylinders by removing a spark plug after turning it over. If the plug is wet then fuel is getting through. if not check the Fuel tap is turned on and that the fuel filter isn't blocked

F1 light comes on bike cuts off of my 2008 gsx . i change oil -gas- and bought it to the shop and the same problem. when i turn the bike on i runs for a little while then turns off

F-I is fuel injection system telling you to clean air-filter,fuel-filter and clean the fuel injector system. This is a good start.

Runs good if you ease into acceleration and while its in park but when going down road andstep down on gas cuts out and looses power

Here are a few things to check.... One, make sure air filter is not dirty/clogged etc. Robbing the engine under heavy acceleration of air, will cause power loss and too heavy a fuel mixture. Secondly, depending on miles on the vehicle, a fuel filter is located under the drivers side, against frame. This filter can get clogged/dirty also and keep the vehicle from getting fuel at heavy acceleration. Those are two cheap things to check. If those don't work, look to get new plugs or add fuel injection system cleaner to your gas for a couple of tanks to help clean up any buildup on the injectors and plugs.

Hope this helps! Let me know!

Trouble with the car starting it has 55000 miles on it. it eventually starts after turning it over 2 or sometimes 3 times. im thinking it must be the spark plugs

Im not sure if that is the issue or not. It is possible but before I would tell you yes, I would want to know if you have changed the following as it is requested in routine maintenence.
air filter and fuel filter?
routine services? have they been done?
2005 really should not require spark plugs unless you have driven 100000 miles already.
If the answer is yes to all I have written. i would indeed check the
plugs but also consider checking air filter look inside throttle body with the hose off to see if it blackish looking, also try to put some fuel injection system cleaner in your vehicle with at least 3/4 of a tank of fuel.
You may even consider haveing your fuel pressure tested. These are things to always consider when it comes to hard starts.

My CBR 600 fl 1990 runs fine then cuts out after 1-20 miles.

I think the gas cap should be vented.Is it possible the vent is not working and the tank is forming a vaccuum stopping the fuel flow?Maybe try riding with the cap part way open with only enough fuel in the tank for the test.(So no fuel splashes out).
I read your problem and saw "any help would be appreciated" and this popped in my mind about the vent.
I hope this helps.

Engine stalls after running for 25 miles?

Sounds like a fuel or intake problem to me, start the bike and spray brake cleaner onto the intake where it goes into the head, if the bike stumbles then you have an intake leak and have to change the seals or just tighten up the intake manifold. Another thing you could do is remove the carb (if it is carburated) remove the float bowl and clean everything including the jets, you could have some **** in there that is plugging things up. Also try removing the air cleaner and spraying a can of carb cleaner into and around the carb. Also try removing the gas tank and completely cleaning it and the petcock screen out, you could have something in the gas tank that is migrating to the petcock and causing a blockage.

Engine cuts out

It sounds like something is preventing the bike from getting fuel. Check fuel filter, fuel tank vent, air filter too. If you have vacuum building up in the tank, letting the bike sit for a few minutes slowly releases that vacuum allowing the pump to pull fuel easily again for a bit. Next time the bike quits open your fuel tank. If you hear a whoosh of air being sucked in look for a plugged vent line. A plugged air filter can have a similar effect but the only way to check that is change the air filter or look at the one you have. It would have to be really, really dirty or plugged with some debris to cause this problem.
