Hi

Im new to these trial bikes bear with me for my lack of knowledge.  

Bought a bike yesterday started on the fourth kick at the shop, tried starting this morning and no go.  I do reset the ecu and press the kill switch before trying to start.  

 

Many thanks in advance

Try again without even touching the throttle

Thanks for replying Basil.

 

Already tried without throttle.  

Took spark plug out, was black so i cleaned it and put it back in with no Joy.  Ill get a new plug on monday.  Also increased the idle, made a purr but thats all.  

 

Just to clarify.. Is this a new bike or new-demo bike that you got from the shop?

The bikes a 2015 model, 

Well as you suggest try the new plug although its not unusual for them to be black in my exp

good luck and let us know the outcome

Did the folks at the shop show you that the 4rt is not designed to be kicked over too fast...more of a steady push through with kick lever, booting it over too fast.. just does not work. 

 It takes a slow steady kick. You do actually give a little throttle like you are just taking up the slack in the throttle. Helps if the bike is house temp, not outside temp.

Absolutely 0 throttle should be needed, I have never been able to get mine started with even the slightest throttle.  

I found out that two ways to rest work, option one kill switch and 0 throttle with a minimum of 2 kicks 3 seems to be better or, option 2, no kill switch and full throttle with the same 2 to 3 kicks, though I believe the full throttle option is what is in my owners manual.  

Good luck.

open throttle fully and slowly push through kick start 3 ish times.

this is the reset that worked for me .

kick over with a firm push id be surprised if it took 4 to start.

if it doesnt new plug, if that doesnt work take it back.

I had some problems with my 2015 starting so I increase the tickover just slightly. May be about 1/4 of a turn after resetting the ECU (3 full throttle kick) and trying 3 steady kicks. Then repeating the process. I recall it was about 3/4 to 1 turn I eventually increased the tickover. 

When starting I found it best to leave my hand off the throttle all together until I got used to not moving the throttle when starting. I think it’s a natural reaction to just pump the throttle slightly when kicking the bike. Remember telling someone to stop pumping the throttle when starting a 4RT and he gave me a curse response about “he wasn’t” but you could see that he was. 

Thanks for all your response, ill give it another go when i get a new plug.  

Will a CR6ah9 be ok?

Standard is CR6EH-9, optional hotter plug for cold weather is CR5EH-9. May want to try the cold weather plug.

And the idle may still be too low, you may want to try the process Barfy mentioned. Or, I've found setting the idle screw 3-turns out from full-in will usually get to starting. You may have to turn it in a little from there once it's going, since it may be a little high.

If you don't have an Owners Manual, you can download one HERE.

Give it one or two slow kicks with the throttle half open, then kick it again with the throttle completely shut and she should purr into life. 

I believe they need the fist two kicks to prime the fuel system.

Why are you pressing the kill switch at all when trying to start it?
