Just another dumb question ,- i have'nt read through all the posts - Have you checked your fuel pressure regulator??
I have not looked into the fuel system at all yet. When these issues all started that was the first thing I thought of but was not familiar with the bike enough to get into the pump. Now that I know how to drop the swing arm I think pulling the fuel pump will be my next rainy day project.
Any good additives to try before pulling the pump? |

Have never heard of one of them going bad, Anyone else have any thoughts on the regulators screwing up on these pumps??? |

wouldn't hurt to go ahead and change the coil pack. If this dosn't fix your problem at least you have a spare. Add some Chevron Techron this does clean the throttle body and intake valve's, I have used a boroscope on my bike and can see that it works. Follow the instructions I used the concentrate. |

I replaced the ignition coil with now change in performance. I did notice there was some discoloring to the old one, or maybe just a different color silicone..
Next up will be Chevron Techron. Then maybe I'll have to pull the fuel pump. |

save the old coil as a spare,by the way my duralast TPS has been working fine and is made in germany like the OEM. {Keep the new one and the old one probably not the issue.IS the bike riding better as you have mention above or is it still missing every once in a while. |

Doberdann1019, do you have the ability to datalog? If you can record a riding session where the problem happens, I'd be glad to take a look at the log. At the least, many suspects could be eliminated. |

Gabby duck, it is still missing every once in a while. No real changes, and its very random. Sometimes it happens hot, sometimes cold, sometimes open loop, closed loop, low fuel, high fuel.. But only sometimes, its very inconsistent.
Readyxp, I can datalog. I have a bunch of data saved already, but will get a fresh session of 20 or 30 miles. I'd really appreciate you taking a look. |

Keep us inform once ReadyXB gets the data we will figure this out. |

We've had some pretty bad weather so I haven't gotten a chance to log data yet. Hopefully tomorrow. |

Just an update, after Readyxb looked at my logs he thought it was a ground issue. I polished all the grounds with a dremel and steel wire wheel. There was some corrosion on some of them. Now the bike runs great! No issues so far but its only been 30 miles. Once I get to 100 miles I will call it fixed.
Thanks again Readyxb, I can't thank you enough. |
