Can i use fuel cleaner of some kind on my yamaha r6 2002 to help my carburetor before i get it done, i'm broke

I would double check that you have carbs and not fuel injection.

service the freaking carburetors yourself what kinda biker are you ?

Any carb or FI cleaner can be used as long as it's used in the proper proportions, i.e. if the bottle treats 20 gallons, don't stick the whole bottle in a 3.2 gallon tank. Get a measuring cup with fluid oz. and use that to measure out proper amount. Oh yeah, don't use the measuring cup to measure out food anymore after you've used it for chemicals. You can get a cheap measuring cup at the Dollar store and go to Walmart and get their SuperTech FI cleaner for 98 cents a bottle which should last you for 3 or 4 tankfuls.

Use the fuel injector cleaner only. Others are usually not kind to your carb seals and O-rings. The stuff is highly flammable, just like gasoline, so treat it with the same respect as gasoline. The ratio you use is not limited to what is on the bottle. If your carbs have not been cleaned for a long time, pour half the bottle of injector cleaner into a full tank of fresh gas. Then drive the bike. If the gas has been sitting a long time (four months or more) and it was not treated with fuel stabilizer, drain it and replace it with fresh gas. Do not let the bike sit around, as the cleaner will do nothing unless it is running through the carbs, along with the gasoline. Leaving the cleaner in the tank for a while may not hurt anything, but your bike is unknown and the cleaner you will choose is also unknown, so there is no way to estimate risk, so you should plan to fill the tank and drive the bike right away. One treatment is likely to be all you need. Drive the bike until the tank is almost empty, and if it has cleaned up enough, then go back to normal gas only and fill the tank with fresh gas before you park the bike. If it still is not right, split the balance of the cleaner over two full tanks, again running the tank to near empty before adding more fuel and cleaner. This should clean even dirty carbs sufficiently for continued use. This stuff really does work well. After moving into a new house, I parked my Honda in the garage and forgot to put fuel stabilizer in it. It sat with stale gas in the tank for about eight months and it would not start. After draining the old gas and putting in fresh, it started but ran so poorly I was reluctant to take it anywhere. A half-bottle of injector cleaner in the tank and a bit of patience as I drove the bike allowed the cleaner to work wonders on the carbs. It just got better and better as I rode. No other treatment was required.

with teh engine being just inches from your body and a chance for many things to go wrong, i would say no. Wait and have it serviced... in the mean time... enjoy the bus
