what could the problem with my 600 will run fine but dies anytime it falls below 1000 rpm?

Answer 1

It sounds like dirt in idle circuit of carb, or vacuum leak at intake seals.
Check your spark plugs and air filter. If they're OK;
Turn the idle mixture screw in gently until it seats. Count the turns that it takes until it seats. Then pull the idle mixture screw out and spray some carb cleaner into the hole with the nozzle tip of the can then replace the needle, screw it in 'til it seats and back it out the same number of turns that it took to get it to seat (from it's initial adjustment.)
To check the intake seals, spray some WD-40, Starter fluid, or use an un-lit propane torch around the intake seals. If the engine RPMs change, the intake seals are bad.Good luck

Answer 2

If it is a carborated bike, sounds like the idle is set alittle low and needs to be adjusted. If it's an injected model. Could be a number of things. These days there are sensors and relays that help control air/fuel mixtures, and would need to be checked by a professional to ensure the right thing is being worked on.

Answer 3

Don't let it run below 1000
It's better for an engine to idle faster, rather than slower.

Answer 4

does it die when you're riding it, or idling?
if its when your riding, then your riding too slow! use more clutch and go quicker
if its when your idling, like the first guy said, could be your idle mixture or your injection
it will be fuel related for sure

Answer 5

most sportbike engines will die at around that point... the idle should be a little higher. try 1200 and see if it goes away.

Answer 6

it could also be an electrical problem.... maybe not sparking great at low RPM.. or the alternator isnt alternating..LOL
