I noticed that you sent this quoted response a couple of years ago to a fellow who had a problem similar to my CBR954RR. Difficult to start but once started and warmed up it starts immediately upon cranking at 0% throttle. Checked the fuel regulator and it didn't have a ruptured diaphragm. Manifold pressure was in spec at 200 mm Hg. Put in a new fuel pump that operates when ignition is turned on. I believe the wax units are functioning properly because when it starts it runs around 2,000 rpm and when it begins to warm up the idle gradually reduces to a steady 1,200 rpm.I would guess it’s either to rich (you’ll smell gas in the exhaust) or too lean. Starting is 0% throttle and <1500rpm so you could try fiddling with the fuel map in the Power Commander and see. Just small changes and keep a record of what you do, or save the map each time under a different file name so that you can roll back the changes if needs be
Thanks for the info. Yes, I've watched a video on how to take the injectors out and clean them via a cleaning kit.that might help, however I missed the bit in your post about it being stood for some years - it might be worth having the injectors cleaned professionally, i,e, not with fuel additives but take them out and send them to some place that know how to get the n clean!.
Okay, I may be overdoing it with 6's. It has been about 2 1/2 hours since running and the bike engine/ exhaust was cold. Started up first try and cycled it a couple of times. All starting attempts were sucessful.
I do think it needs to get some heat in the motor between cold starts to ensure there is no unburnt fuel in the combustion chambers. If you have access to an exhaust gas analyser it might help but cold starts a funny think if you changed anything from standard!
Dude....if u want us to help you you GOTTA proof your post before you hit send, so that it makes sense to the reader!......PUNCUATION SAVES LIVES!!....Update: After working on the bike removing the PClll usb, and going through everything I could, still not running. Took the airbox off to check the injectors and it fired up, turned the bike off and went to crank it back up and nothing. Now they will spray some the just stop turn the bike off and move the tank they will spray a little then stop. FPR is working. Fuel pump is coming on. I’m getting spark so at this point I’m lost.
I removed my Power Commander and never noticed a difference. Lap times were the same and I stopped worrying about some glitch in programming!Had same problem on my 2000 929. I found it was simply the engine mapping. Remapped engine and boom problem went straight away.
