Hello all,

With the cold months upon us, we have had some very nice days but temps not above 50 here. I have a 98 t595 and I was wondering how many of you who have a t595 ride when its cold, and how difficult it is to start when its cold. My bike absolutely will not start when it is cold. I have actually had issues starting it since about the outside temperatures have fallen bellow the 80's. To start it, I have to put a floor heater at the front of the bike and have it pointed up toward the radiator for about an hour/ hour and a half then it will start. Once running I have to keep the rpm's around 2000 till it gets all the way warm or it will stall out. Once warm the bike starts back up if shut off and runs great.

Ive heard these are "cold blooded" but I wouldn't think I would have to go as far as I do to just get it running on its own. Open for all inputs and suggestions. Thanks in advance.

The few cooler days I rode in before I took it apart it was significantly more difficult to start up than on a 65f day.

I was idly curious but since I'm performing a full maintenance check this winter I figured I'd worry about it in the late winter/spring.

Would like to hear thoughts on it to know anything else specifically to look for

Get yourself TuneECU, then increase the fueling coefficient for colder temps.
This is under the 'warm-up' table



Add a few points to the appropriate temperature ranges to increase the fuel at those temps

You may also generally just need an increase in the CO (idle Fuel Trim), which will affect overall idle Air/Fuel Ratio / performance throughout the whole temp range.
Note that for idle fuel trim that is a 'real-time' active adjustment (vs the warm-up, which requires changes to be saved and map reloaded);
also it only becomes active at full operating temp, > 85C

Rlynn1988, I ride mine in the cold and usually don't have much of a problem starting, but once in awhile requires a little nursing to prevent stalling. TuneECU will be used to fine tune the parameters.

Ahks, If you're taking the bike out of service for a couple of months this winter here's a few of suggestions beyond a regular tune-up:
-Check cam/valve clearance
-Check all of the vacuum lines between the IAC manifo.ld and the throttle bodies.
-Replace the in tank fuel hoses.
-Replace the throttle body gasket and seat each throttle body individually.

Already planned on the valve check (and try to figure out if a PO put the updated cam in)
Vacuum lines already checked and appear almost brand new
in tank hoses is a new one, thanks, same with the TB gasket.

If the engine number is 61508 or higher, the factory installed the "new" cams.

I will definetely give that a shot. I do have tuneECU already but I am fairly new with it (the only thing I have acutally done with it is reset the tps). I am sure I will be back with questions about the program but since this is a 4 day weekend I figured it would be perfect time to tackle the issue before it gets really cold.

Noob question,

Does the bike have to be running to adjust the fuel with tuneECU?

DEcosse

To adjust the Warm-up map, no. Makes changes and save and reload saved map into the ECM
For the CO adjust, bike needs to be running and at full operating temp (>85C) before it becomes active. Then will change real-time while running.

Another question, by "adding a few points" what should I be going for? Like at 14 degrees celcius which is close to outside temp right now, the a/f is at 1.00, should I bump to 2.0 or say say 1.1?
