Didn't know if anyone could clue me in. My 250 isn't as responsive in cold weather as it is in the warmer months. I didn't know if it is just me or similar things are happening to other people. I always warm it up aswell before riding but still lags alittle here and there. I didn't know if it was normal in cold weather or if I would need to get something checked.































Thanks!

my 2000 zx6r was the same way mabye it has something to do with the carbs cause my 06 636 has no prob in cold weather.

Yeah same here, it's got something to do with the CARB, i had the same problem with my 500EX.















I have a fuel inject R6 now.

Try using a lighter weight oil. Warming up the bike is good, however, oil circulation is critical especially in cold weather.

for 1 its the oil u need to run a thinner oil in the winter because it takes longer for the oil to thin in cold temps. I have multiple bikes and cars with and without fuel injection and fuel injection runs a little better in the cold because it resets its self for the colder air
