ok its done now here are some pics. the bike before the front cylinder dropped exhaust valve.
here is the front piston damage
and a top shot with rocker off
now the rear piston contact
and some metal bits formerly the valve guide and valve springs and some other bits
this pic is after i fixed the front cylinder
and finally here is the bike done
I got about 117 miles on it now. I would have had more miles if it didn't start raining, I was not comfortable breaking in a new motor while it was raining. |

The bike looks great.. now put a sock on that filter and keep riding rain or shine! I got Betty in the rain for the first time yesterday. Was kinda surprised at how easily she cleaned up.. Any chance you'll be at homecoming with that bike? |

Screw running the sock on all the time...the sock is only for rain. Plus you lose HP with it on, it's been proven iirc |

Prey - Looks awesome! Maybe next year I'll have the funds to rebuild my motor. |

Brin, it is proven. You'll lose 4 HP or more with the sock on. |

Russ, looks good! I was posting from my phone and the pics didn't come through...Now you need the race exhaust. =) |

I don't think i will be at homecoming this year i almost never have time off. I must remain here to run the business. man i wish i had my old job for the time off but the pay really was so meager. Now i make good money so i figure i would fix this bike vs buy a new one. I love this bike and the looks i get while riding it. Today the guy at the auto part store had his neck turned so far to figure out what i was riding i thought he was an owl. |

New top end looks sharp, I hope the ride is worth the wait. Sure do have nice weather for it now! |

man this thing is a BEAST!! I have only had it to 3500 rpm and it is getting faster by the mile. I will post a video of the motor sound tomorrow, It sound's so lobe-e, now it idles all wicked sounding. this is very sweet and better than i thought it would be. just need the break in so i can get a real tune. I am thinking of going to California to have it tuned buy JTS performance, But also i was wondering how the tuning would be at sea level and then bringing it to a higher elevation after the tuning. This sounds like it would not work! |

Just an update: This bike idles like another bike i know of, and also has similar parts. I will do a comparison and check back. |

Up to 220 miles on the motor just about time for the oil change. Also i have tough decision to make about the dyno tuning! I really want too ship the bike to JTS-performance for a full custom tune\map then fly down and ride it back. The plane ticket is $90 but the shipping is $529 And the reason is i can't find anyone here that will tune it right and they all say we can try. What do you mean TRY IT? Not on my bike. I am tired of people who say they can tune the bike and then you tell them what ECM spy is and they all say we have never done anything like that but we can TRY. I could drive it down, But i don't want to sit behind the wheel for 10+ hours to get there, It would be about $250 cheaper if i drove it down in the shop truck. Either way its going there for tuning, I just hate to drive for long periods of time. |

IIRC Phil is tuning his own bike using ECM spy and never had a clue about it. |

I have been checking this out for a long time now and talked with terry this morning about bringing it down, Also there is a chance i will get to meet FMJ and see his BEAST of a motor he is going to run at Bonneville. I like the pros to set me up sweet, I don't mind spending money on things i really like, Also i have 3 ECM's now and am going to flash the race maps into 2 of them and test it on the ghost rider to see if it will smooth it out a little more. |

Russ, I think I used to teach with a guy that's supposed to be pretty good with the dyno tune, works at the Triumph/BMW shop in North SL. Can't believe I just remembered that! I'll send out a couple a emails and see what I can find out. |

I'm not really tuning mine, just adjusting it by mass percentage changes across the entire map in order to get a stable afv. I know ecmspy will datalog, but with the price of wb o2 sensors and all the necessary tuning tools, I think ill have a shop do a full dyno tune once she's broken in. |

Phil, you may not be able to get a steady 100% AFV by just tweaking the fuel maps. As long as your value remains between 95 and 105 you are good to go. I spent a great deal of time trying to do that and it kept shifting to 105 and stayed there. There are other parameters which affect the AFV beyond just the fuel maps. The nice thing about "professional" tuning is that it focuses more on air/fuel ratio (AFR) to maximize power/torque across the rev range. Just my 2 cents. |

Right now everything is 5% richer than the race maps and I haven't moved from 100% AFV during all 500 miles of break-in. As far as getting to operating temp and staying there, she's doing great. There are however some pretty obvious spots in the fuel map that aren't as good as they should be. When I get back from homecoming I'll be looking for a shop to tune her properly. Right now I think she's perfectly safe to ride without being too lean anywhere. |

hm...my AFV keeps dropping to around 83% Should i maybe richen everything up a bit? I live at 5,000 above sea level and often go as high as 7,000 or 9,000, sometimes even 11,000 |

In my opinion (by no means a real expert), 83% is an indication that the maps are a bit too rich regardless of the altitude. If it were my bike, I would lean out the mixture across the fuel map in small increments and see how the bike responds. |

Sweet there is a shipping terminal in my state in my own city and can get it shipped for $359 to Sacramento terminal and JTS will pick up for $40 in gas, I am really liking the accommodating and personal touch of these guys here at JTS. the service was better than experienced before...EVER!! Also i will look forward to damn good service! as i have a dam good feeling about these guy's. I like these guys attitude very much!! |

I am glad i am shipping this bike to get it tuned. It is so far out of whack i wouldn't dare hit WO throttle. I checked out the afv again and it was 82% so this thing is running rich in closed loop and has never been in open loop yet. The race ECM isn't enough to do the job alone, This bike needs a tune ASAP. While it is there i will have them do an oil change, Adjust the primary tension, And do all 3 isolators if they are bad as well and loosen my primary drive belt. |

Sorry if this is a bit off-topic but I have always wondered how the "dyno tuning" is actually done. What tool(s) would they use and what parameters are adjusted. It appears to me a tool like ECMSPY allows you to adjust injector pulse width and timing across the entire RPM range (albeit in a no load condition) so I am guessing the dyno provides the additional view of torque as the fuel/timing values are changed, all while the bike is under load. Just wondering. |

Once it's tuned you're gonna fly down and ride it home right? |

The ECMSpy is a great tool for initial tune and dial-in of setting up the front and rear cylinders properly. For true, (LOAD-BASED) technology, you really need to look at installing the DOBECK PERFORMANCE TFI (or like unit) in conjunction with the Race ECM (tuned with the ECMSpy). Just installing this load-based TFI unit on made this bike really perform to the full potential. My 1250cc rocks hard and the roll on from 80 MPH to 130+ is like instant. I had problems in the midrange load and when I got the TFI dialed in it made all the difference in the world to the tune of an additional 10 rwHP vs. not running the TFI. |

I was thinking of the dobeck tfi kit but was told by some very wise folks not to use it and i will respect there opinions on the usage and get this tuned by some pros and i will post the dyno results when they get it mapped. I have also looked into other options such as a different ecm setup also using different set ups. |

My understanding is that ECMSpy is as powerful a tuning tool as is available for anything. Far more versatility than any piggyback system. A good mate of mine who has 9 Ducatis told me it would cost about AU$7000 to buy the stuff required to do to his Dukes what ECMSpy does for FI Buells. |
