hi..
i just bouight my 2nd 09 SG last week, the odo 2500 km now....
when i start it in cold engine temperature, the idle will jump from 1100-1300 for 1 minute....
after the bike warm, the idle will stable at 1000ish...
its not a big problem but pretty annoying me....
my bike is 09 SG, rinehart slip on, stock headpipe, stock air filter (just cut a big hole on the back cover of air filter to let the engine get bigger airflow)..
my idle bouncing before i cut the hole...
any wrong with my set up..??
why my idle will bouncing ?? do i need the pcv ?? do i need a new breather kit ??

thanks
regards

 

mine does the same thing. i will be following this thread as well!

 

Yea whats wrong with that?
I dont know if I'd say it last a full minute but the idel is definity up a lil in cold starts and then (I guess) the ECM tells it to come down. Doesnt every motor do that?

 

Sounds pretty much normal to me. High idle for a minute on cold starts is about right.

 

no different...
if the idle going up say 1300 then stable there, then after warm it will drop...that is normal...
but my case is different, the idle wont hold at say 1300...it keep moving between 1100-1300 for like 20-30 second then drop to 1000 then stable...so its different....
something like unstable supply of air/fuel when its cold....

 

its called any electric choke. your idel shoots up gets warm and goes down. Every bike should do it just like a car does. so idk what the problem is?

 

its normal if the idle going up and stable at that rpm...mine is different, it will going up then jump/bouncing between 1100-1300......not stable....

 

ahhhhhhhh.....

 

A wavering idle....thats annoying yes I agree....

 

yes..wavering idle....
how can i fix it ??

thanks
