I believe its the correct one. IWP043 is what was in it already and the few searches I was able to find reference that one as well.

Had the bike apart and added new radiators, injector and plug. Got it to fire up and got idle set up. Still issues though I can't seem to figure out. I can start the bike easily cold and let it warm up etc and shit it down and it will fire right back up. I can test throttle response and what not while it's running with no issues and it would hold idle no issues and restart. As soon as I take it out for a quick spin, even if it's 100yds up the street and back, once I shut it down it will not fire back up. Going to change the fuel pump out again as I noticed when I pulled the tank the last time fuel was still running out of the line even with the pump not getting power. That doesn't seem right to me with a FI bike. I'm thinking once a load hits the electrical somewhere its causing the issues. Maybe the new fuel pump is bad, maybe a temp sensor or another sensor, maybe coil, etc. Any ideas?

Maybe the pump had pressureised the line and that caused some of it to flow out when you took the tank off?

Can you post a video of your no start condition? Maybe it will be easier for others to spot a potential problem that way. Im not sure if this applies to the kokusan ECUs but I think some of the fuel injected bikes had problems with ECU pins having poor connections. Maybe look into that aswell?

Bike is apart already, going to swap the fuel pump out tomorrow and go from there again. Will try to grab video once back together again. Just odd it only won't fire after its actually ridden and shut off. Sitting idle to warm up and cracking throttle i can shut it down and it will start back up. I'm wondering if the fuel bag came off or something and there is minor debris in the tank that when ridden its enough to suck it through the pump and then clog the injector just enough. Maybe the coil or another sensor is the culprit, just don't know at this point.

Gasser Nate, everything I've found online suggests the same thing about the efi system. No as problematic as previous one. I'm just stumped since it always happens after actually riding it. I'm thinking it's a sensor or fuel pump once it really needs to work since otherwise it fires up easily.
I read these bikes like to it up around 2k rpms, any idea what idle is with a cold start during warm up? Last edited by AzWickedSS; 10-11-2021 at 01:15 PM. |

They are supposed to idle at 1800 +/- 50rpm.
They also do not have a fast idle circuit as such but do obviously have and enrichener map.

Pulled the cam cover off and was able to get measurements. Guessing they need adjustment as they are a bit tight. Trying to find what the exact range is though. Read .15mm intake and. 20mm exhaust on another thread but not sure what the gapping is around those numbers.
Readings I got Intake L -.10MM R - .13MM Exhaust L - .18mm R - .18mm Now I saw several people say DRZ shims work, any idea if its year specific for those? |

The shims are 9.48mm - the same as DRZ and many other bikes.
Intake 0.10mm ~ 0.20mm Exhaust 0.20mm ~ 0.30mm I have always set mine up according to this and tried to get it in the middle of the ranges so 0.15mm for the intake and 0.25mm for the exhaust. |
