jimmyl Posted November 1, 2010 Report Share Posted November 1, 2010 Dont forget to push kill button afterwards. Never stall engine - always stop with kill button. If it doesn't start first kick snap open throttle and press kill button. If still don't start then try the 3 slow kicks throttle open.

tjums Posted November 2, 2010 Report Share Posted November 2, 2010 (edited) Where does this story come from ??? That would be the Owners manual...

dye29 Posted November 2, 2010 Author Report Share Posted November 2, 2010 i ment fully reset but ye this sounds normal not to start first kick is it as i have to proper kick mine but if i wind throttle back and release then kick she runs so this normal Quote Link to comment Share on other sites More sharing options...
scraggydog64 Posted November 2, 2010 Report Share Posted November 2, 2010 What year is your 4RT? The reason I ask is that I had an 05 (My son still has it.) and it was a great starter, generally first kick. I now have an 09 and it sometimes starts first kick, it often does not. I have to hold the throttle wide open and kick slowly once (I was told to kick three times initially.)to reset the ECU, then close the throttle and it will start first time. I have heard others say the newer models are not as good at starting. It's the idle speed. If I up the idle speed it will start reliably first time every time but the tick over so high its too fast in a section.

jimmyl Posted November 2, 2010 Report Share Posted November 2, 2010 Check throttle cable is not too tight and holding throttle open slightly. Presume you adjusted tickover on throttle body air screw and not with cable adjuster on twist grip. Make sure you have throttle closed when starting and not holding open slightly without knowing Quote Link to comment Share on other sites More sharing options...
dye29 Posted November 2, 2010 Author Report Share Posted November 2, 2010 hy throttle is ok and ive just set rpm to 1800 from the throttle body its strange Quote Link to comment Share on other sites More sharing options...
barfy Posted November 2, 2010 Report Share Posted November 2, 2010 I had some problems with my 2006 model starting first kick. To test the throttle cable I slackened it right off so that the throttle didn't open until about 1/8th of a turn. It did improve the starting but was too slack to ride properly. I eventually tightened the cable until it was ridable but starting wasn't so reliable. . A few weeks later at a trial someone saw me kicking the bike (resetting the ECU with three gentle kicks) and mentioned that I was just opening the throttle slightly when kicking. For a while I got into the habit of putting my hand on the top of the throttle rather than the grip. It took a real conscious effort not to open the throttle when kicking the bike but I've mastered it now. Quote Link to comment Share on other sites More sharing options...

honda_freak Posted December 3, 2010 Report Share Posted December 3, 2010 I found a very interesting document - details of a patent from Honda Motor Corp.. describing how the tilt sensor works and how the engine control unit (ECU) decides when the motorcycle has been given the proper input from ambient sensors, ie information from throttle potentimeter, water temepratur and how many revolutions the engine is running. By looking at flow chart gives a better understanding of how the motorcycle is ready for ignition and fuel injection or put another way - how the engine management thinking! It is very dry reading, but very educational - you are now warned. Happy reading.
