  • Morning hard start

    I had a brand new 98 tlr, never had a problem starting. I then bought a 2000 TLR with full exhast, never maped. Major morning start problems (killing the battery). I hooked up the yoshi box...nothing.....I blew the motor (another story) and stuck a 99 motor in the bike....same problems...swaped the fuel injection back to my 2000 motor's fuel injedction.....still hard start....put in BMC air filter, and PC II with downloaded map....great power addition and smooth idling for 1000 miles before it fowled the spark plugs but it was still taking 30-50 seconds to crank over in the morning. It's like the fuel systems not pressurized. Any ideas. A dyno run would fix the fowling plugs and make the map smoother but what about starting cold. Air temp sensor? I got a brand new battery and Im getting tired of jumping my bike off my toyota in the morning.

    have you checked throttle body sync and tps setting? does it have a TRE fitted? maybe check the above mentioned and remove TRE if fitted and try it. a lot of folks have gone with a switchable TRE for cold starting issues

            Sounds like it's about time to get another bike!
            It may be that your sole purpose in life is simply to serve as a bad example.

              My bike is very cold natured and I have'nt even owned it in the winter yet. I have found it helps mine to turn the key on and wait for the fuel pump to stop running. I then flip the kill switch off and back on to start the pump running again, then start. It does seem to start a lot easier than just turning the key on and hitting the start button.(just my opinion) All your swapping have you been using the same fuel pump?

                I have messed around with the TPS and TB sync a lot. I'll try the TRE issue that's something different. Never thought of a fuel pump being the issue. I do still have the same tank.

                      Kinda obvious, but if you aren't waiting for the fuel pump to prime the system, then it will definitely start like crap...
                      Mine starts in 1-2 seconds first time every time (and I ride sometimes when it's 40 degrees outside!) if I do the following:

                      Flip the cold start on,
                      turn on the key
                      wait until I hear the pump stop
                      hit the ignition while jazzing the throttle between 0-10% of it's travel (just to give it a little extra gas to work with)
                      I'm a little wary with jazzing when the oil hasn't had a chance to get around the internals, but then again if I don't, it sometimes dies after a second or two. We're talking jazzing between 1500-2500rpm or so.

                        Any FI light? My understanding is the system will fault to a rich condition if there is a faulty sensor (fouling the plugs). Jump the ECU to dealer mode yet

                        Might be the ECU if you are having the same problems after changing engines. Were you using the same air box with both engines? Might be a problem in there too. Flapper valves stuck

                        About the TRE. Do you have a nuetral light? If you don't then it might not be done correctly and the bike doesn't know what FI map to use. A fixed TRE will make it hard to start, but not as bad as you describe.

                        Weak spark? Improper gap? Weak battery? Weak coil?

                        Hmmmm any I missing anything else? You need fuel, air, compression, and spark for the engine to start.
                        Don't know how it works? Take it apart and find out!

                        Here's how it sounds.

                          Trust me. I have had this bike down to nothing but the frame after I blew the first motor. It's been apart I know how it works. Coils are good and changed. Spark plugs are clean and pre gapped (although they fowl after 2000 miles). I have definantly gone through new batteries ( this problem rapes them of energy).No Fi light. I do have a neutral light. About the dealer ECU. Do I need to do that with a downoaded PCII map installed. And yes I am using the same airbox but that has been triple checked. The only thing related to the airbox I could come up with is the outside air temp senser which is what tells the trottle bodies how thick of a fuel spay to adomize in cold situations. It's been changed out too

                              Its the starter relay, replace it and all will be well,or ill buy you lunch.........My hard start problem took me months to find, I tried everything from adjusting the gap on the ckp to the rotor, to batteries and Reg/Rec. then the the starter realey died and voilaa fires right up everytime
                              AHHHH nothing like a handfull of throttle to wake a guy up in the morning... well that and sex
