Hi, I have converted my CBR 125 to 170cc, DOCH and race cams. I have bought the PCV and autotune. I can't adjust the fuel correctly to run at idle. I think I will send it to a dyno but I want to figure out why it won't run at idle even though I have adjusted at a little higher rpms where i get the correct AFR.

 

Hi, I have installed a autotune with a o2 sensor. on a cbr 125 converted to 170cc, DOHC and race cams. after a couple of tries adjusting the afr level i can't get it running idle. i have only been able to adjust the fuel correcly from 2000-5000 rpm up to 10% throttle. can you help me?

 

We don't even have a CBR125 here in the states, so I doubt anyone will be able to help much. We only have a few members from other places in the world, perhaps they can?
