I have a 2000 gsxr 600 carb it rattles when the rpms go up and smokes till its warm is it cheaper to buy a new motor or fix it from the day i got it i cant get the front end off the ground is that bad rattle and smoke just started

Lots of things could cause this! Oil being over full can effect it this way but would have to be really high. You would also notice a lot of smoking if this was the reason. Carbs not being Sync'd correctly will cause this. Main jets in carb plugged or wrong size. Float level off can cause this. Timing off can cause this. Most likely the problem is in the carburation. Hope this helped!

The carb needs to have the jets cleaned and you should also have the carb boot checked for any cracks or leaks.

The biggest difference is that the 2007 GSXR 600 has fuel injection instead of carbs. The FI symbol will alert you that the sensors on the Fuel Injection system have found a problem. When that happens, a dealer will be needed to hook up a code reader to see what the problem is. A dirty air filter is something you can fix. A fuel mapping problem is for the dealer to fix. Minor FI problems still let the bike run. Major problems shut down the fuel system so the engine will not even start. Other than that, just be sure the bike shifts smooth and easy and that all electrics and brakes work properly. How old is the battery? How much life is left in the chain? Does the clutch operate properly? How soon before new tires will be needed? I hope this helps. Please rate my answer.

sounds like a vacum leak. get a can of wd-40 and spray all around the carbs when the motor revs up thats the source of the leak. fix or replace that part and ride into the sunset.

It needs the choke which means it has too little fuel. So the first thing is to run some carb. cleaner through it. If you can remove the air cleaner and spray cleaner into the carb. directly to help it clean. Add the cleaner to the fuel tank by following the direction. Too much will not work better thenwhat is suggested. Gasoline tends to evaporate and leave a varnish like hard coating on the fuel system. Takes a while to clean back out. Store all gas powered motors using a stabilizer product, or completely remove the gas before storage.

sounds to me like your carbs may need cleaning and or a rebuild, i had a 750 katana that would do that as well, didnt want to idle when cold, then too fast when warm/hot, gave my carbs a good cleaning and it cleared up, the jets can get plugged really easily, could also be bad gas, any contamination and or particles can cause problems, especially if the bike sits without running for too long, hope this helps =)

check your copression if its fine take your pipes off and see if the problem still exsites

You need to get some new float needles, and have the carbs cleaned and the float heights set correctly.
