BACK STORY:
I purchased the bike as "only runs with high idle out".
I removed the throttle body, cleaned injector, TPS was set at .47 I reset to .48 (tried .50, .55) still wouldn't idle, at this point it was running the same as when I purchased it.
I was told to try a TPS setting of 0.62, I did so and finally the bike would idle however at this point it ran quite badly, I guess it was from over fueling? It would pop and just not run well at all.
Once I had it idling I then battled the bad running, I did A LOT of messing about before realising the poor running was because of the 0.62 TPS setting.
I have currently gone through:
Replaced complete throttle body (inc all sensors + injector)
Replaced fuel pump
Cleaned all earth points
Changed spark plug
Cleaned the wiring harness inc all plugs
Checked ECT sensor
Current:
TPS set to 0.5.
Bike will idle for 15 seconds when cold (I guess bike is in enrichment mode?)
Once warm it will NOT idle, if it ever does idle it's for 1 second maximum just enough to grab the throttle
When on the stand and revved it will rev out from 0 - 100 absolutely fine
When riding if you are aggressive for example riding in straight lines going from 0% - 100% throttle and not cruising. Once you try to hold the throttle or higher the rpms at a much slower rate you will get a very aggressive juddering / hesitation feeling around 1/3 throttle, once it passes it (aggressively turn throttle) then it's fine.
I am hoping I just need to play with the TPS a lot more and get it to where it needs to be however others opinions are always appreciated. I can get access to a 2013 ECU and coil if people suspect that could be the problem however it runs flawless at high RPM which is usually where the coil breaks down?
Oh also the bike has full yoshi twin pipe, does this mean the TPS should be set a little higher or do you only touch mapping when running an after market pipe? Thanks!
