hello every body,

i'm new to the forum, very informative!

after 5 years without a duc i couldn't resist any longer and bought a 2001 996.

here is my problem:

its in the mid 50's to low 60's here in NC. bike starts perfect with the choke engaged and dies immediately after working the throttle.

it does this until the engine is warm. once its warmed up idle is stable arround 900 rpm.

am i missing something here, my 916 had the old style choke lever and i never experienced any problems.

maybe i'm just to stupid to work the chocke button correctly.

thanks for your input.

You´ll have to be careful when working the throttle when you have the button engaged. It takes a small amount of pressure on the throttle to disengage the button, so it might be just a user error. The button isn´t a choke per se it is only a throttle hold. so it doesn´t reduce air to the engine like a normal choke.

Let the bike warm for 60-90 seconds on the button before taking off, that usaully lets mine get up to temp. I´ve also found that my bike doesn´t like the stock exhaust and dies even in warmer weather when the engine is "cold".

You might want to get your servicetech to check the CO-levels, since those are usually to blame for stalling issues.

How is the bike stored during the night/day?
Outside?
Cold garage?

What are you using as "extras" on the bike?
*Exhaust?
*Airfilter?
*Chip/PC?

Have you had the bike to the dealer/serviced recently?

If you have the termi pipes and the termi chip, You must have had the co-levels adjusted already.

It might just be the cool weather or maybe abit lean on the CO.

I'd check throttle position sensor, throttle body balance and trim pot for air/fuel ratio. I bet it's running lean.

+1 on jwsparkes

Sounds like it´s running lean in low temps.. My guess is that the CO is off and the TPS needs to be reset.


Did it get better ones warmed up?
Was the backfire LOUD or muted?
Did the second cylinder start up when you cranked the throttle?

Take it to the dealer would be my choice. It´s better to get it sorted by a pro.
