Software now working, I have set throttle up, 1400 rpm idle, tps at 0.61v , done the software reset/learn.

Bike still a bitch to start, I doesnt have the factory easy start, but i have hooked up a 12 Li battery .

I have injection pulse,fuel pressure and spark ,you can kick and kick with no start, then randomly it will start first or second kick.

It will set occasionally set a  P1611 Chassis relay  fault  in history but not in active faults, and all actuator functions work  on test.

Any ideas ?

I commonly got the chassis relay fault on my Explorer- never seemed to affect anything.

 Make sure you do not touch the throttle when starting- take the slack out of starter and a good strong kick.  

With a 12V battery hooked up with a momentary switch- holding down the switch while kicking started first kick every time warm, 1 or 2 cold. I also ran one step hotter sparking plug, since the factory one was too cold.

Thanks for the replies, I didnt think the relay code was important but good you confirmed that.

The battery is on a switch , I had 2 of these bikes when they were new , and had no issues starting them.

Converted my second with a Li battery and it was a first/second kick starter.

Im useing NGK 5 range plugs, cant get hotter .

When i enter the page to change fuel ratio the software crashes.

I think ive sorted it now, Injector was dribbling, ran it through the cleaner and bike is lots better.

Reading the previous posts it looks like you have added a battery assist system for better starting.

Below is a wiring diagram from Birkett Motosport in the UK.  I have fitted this system to my 2015 Tri300 and it has made a huge improvement in starting.

I have attached a Word document with some photos for clarity.
