I have a 01' F4I 600 and when I first start it up I let if get to temp first and it feels and

sounds like its running on 2 or 3 cylinders. I take it down the road and at about 12k it

clears up and runs fine. Before it clears up it does smoke a bit (black smoke) and smells

like gas. The bike has a full 2 brothers exhaust. I have had new plugs, timing chain,

tensioner, injectors cleaned, and the bike has 16k miles. I was told that a power

commander or a tune would fix this. Does anyone have any experience with this? Thanks.

 

Anytime you put or run a full exhaust system you should run a commander and get it mapped to the exhaust your running.If you just run a slip on no need -Reeff-

 

It's just running rich on warm up sound kinda normal.

Mine is stock an has a lopy idle before it's warm.

 

It runs the same even after its warm. I have to ride it and take it over 12k to get it to stop. Once it revs over 12k with load on the motor its fine.

 

pc III or whatever power commander is designed for your bike and custom map at your local dealer.....problem solved
