Blake, I really can't open this up on the board as much as I would like to. Believe me, the truth should be told.
The motor is still sat in the bike, untouched from the day it popped. I do know that new base and head gaskets were installed and I'm certain they put it back together with the incorrect thickness gaskets. One day though I might report everything here and on UKBEG, and it will NOT be good for the dealer if I do (believe me there is more to tell than just the motors failure) . I've also got friends in the British motorcycling press too, and they think I should give them the scoop. That could still happen.

Couple of results from today ...
1999 M2 owned by Justin Shilling
Nallin Racing Stage 3 head work
Nallin Racing 1250 kit
SE .536 lift cams
Force exhaust
Mikuni HSR42
Our most popular 1250 combination. We'll get more as well as clean up the bottom end when Justin gets time to do a little more tuniung ... I predict 110+.
2000 Millennium X1 owned by a valued customer
Nallin Racing 88" kit
Nallin Racing Stage 3 head work
SE .536 lift cams
bored throttle body
Force exhaust
This is a mildly cammed 88incher with injection. Should be a terrific all around bike.
We got 127 from another customer's carbureted 88incher the other day but dummy me forgot to grab his files before leaving the shop today. I'll post it another time.

Aaron the X-1 dyno chart has my wife a little miffed at you. Before now all I have done is dream of that kind of power from my X-1 with fuel injection intact. Now I'm actually looking up parts and prices. Thanks buddy. BTW how reliable, compared to stock is that X-1?

Sorry Pilk! But I'll tell ya, a bike like that one is a hoot to ride.
Reliability should be better in terms of longevity of the top end. These cylinders dissipate heat better and last longer, much higher quality valves/guides/seals/gaskets, etc. These cams are not hard on the valvetrain like some others, plus they don't require adjustable pushrods and collapsible covers and roller rockers and hydrosolids.
On the other hand, the extra torque puts more stress on the clutch, gearbox, and belt, so those things are at more risk depending on how hard you hammer it. Most people don't have an issue with them, though. I would recommend a modestly heavier clutch spring ($25). |

Damn you Aaron Wilson!
I'm sitting here thinking....
M2 - perfect commuter bike
1999 - cheap
Nallinization® - reasonable
End result - too much fun for a guy my age
I say again....damn you! |

Aaron,
Pulled the old girl Sunday. I think it needs the lower end leaner. Here is the question "do you think since it has a hsr and we crowded instead of just wfo'd it that lowering the needle or maybe using a smaller squirter nozzle would bring it around?"

New user here. Forgive any improprieties. Will post dyno results as soon as I get them scanned. Ran a 99.43 HP run recently without cracking a bolt top or bottom. Just intake/exhaust/ECM/PCIII.

Ryan,
Please post the details about your engine.
Tbolt_dad,
Looking forward to it, sounds like you have a real well put together machine. When scanning, set dpi to no more than 100 and quality no more than 70%, size must be less than 640x640 pixels. Use the "Upload Attachment..." button below to upload your chart/pic. |

Ryan: hard to see your a/f in that scan, but it looks pretty damn flat to me. I love Mikuni's ">">
Generally speaking, 13:1 or so is where you want to be. 12.5:1 to 13.5:1 is a good range IMO.

See if this gets it
HSR42 w/hand made open element filter
Stock t-storms w/12,000+miles
Andrews N-6
IDS completely gutted(I realize I prob.loose trq)
ProSeries limeter
1250 Millenium Cylinders w/Hurricane pistons
1.7 roller rockers
and alota help from everyone here.
I will get timing and jetting dialed hopefully
in a couple weeks

TBolt_Dad,
Looks like you got the motor that was kissed by God himself. How do you suppose peak HP improved so much without any change in A/F from 6,000 rpm up? Did you play with timing or cams? Looks like you might have broke 100 HP if you had let her hit the limiter. It appears she shut down before 6,800 rpm? |

Blake,
I'll try to get midrange cleaned up(leaned down) and work on dialing in timimg. I would like to see 85+ft-lbs and make that trq curve flat like Illinois!! HP don't mean alot to me I like to stay in midrange for mongo one ups.
Might have to try 88incher this winter if I can get someone to buy my 1250 from me. Should be able to make killer trq with no other mods.
Thanks Ryan |

Blake,
No timing mods or cams. Pure bolt-on power. I will talk with the Dyno guy to find out why the early shutdown. I was shooting for 100HP, just missed the mark. Could have gotten it if the ambient temp had stayed down, or if I had run race gas. |

BTW,
The run in red was just what I was able to do w/out a Dyno run. The Dyno Tech did say he was very impressed with the numbers for bolt on HP. |

T-bolt_dad,
"Very impressed" would be a massive understatement. That kind of performance from a Buell engine that has never been cracked open is truly unheard of. Suggest you prepare for a lot of disbelief from the crowd here, including me.
What do you mean you would get more HP if the ambient temperature had stayed down? Are those corrected results or not? |

The 88" motors are almost scary in a Buell. |

Blake :
Numbers WILL vary from day to day , corrected or not , due to atmospheric conditions at the time of the session. Bad air = less output, conversly , good air = more output , control of temps within the dyno room as well as monitoring engine temp ( infra red temp gun ) on non EFI bikes allows for a more accurate measure of output on a given day , I'm sure AW will agree , we discussed it here about three and a half years ago , way before he was setup with his own Dyno. |

Blake,
A little further along Hoser's line of logic, cooler ambient temp of air allows for better performance (cooler air is 'heavier' barometrically as long as relative humidity does not fluctuate greatly) Too my knowledge, these are NOT corrected results. BTW, the Dyno work was done at a Dynojet Certified Tuning Facility. As far as disbelief goes, I have only my word, and that of the dealer mechanics that up until now have done the regularly scheduled maintenance on the bike. As of the 5th of July, I will be the only one wrenching on the machine as the original warranty is up, and I have found out first hand (much to my dealers and mine own dismay), Extended Warranties DO NOT COVER modified machines. |

Boy T-BoltD if you could get correct fueling between 4500 and 6000 I could see a big improvement in your trq!! It would take care of the dip and possibly bring HP up!
Aaron what's your thoughts?

Looks to me like T'bolt_dad's dyno sheet says cf:SAE in the upper right hand corner.
I'm amazed as well. Hang on to that bike!

Rippin, I think both your a/f curve and his (blue) are excellent. Very flat and right around 13:1. Yeah, yours is a little fat down low but not that much, and I doubt that correcting it will change your torque curve much. The torque curve is as much or more a picture of cylinder fill as proper a/f. The pipe will have a much bigger effect on it than moving the a/f half a point.
As far as correction goes, I see my biggest variations with humidity. Even though the weather station monitors it and factors it in to the correction, it doesn't seem to do a good job. More humidity makes the results lower for me. Temp variations, the dyno seems to do a good job with. I get my best corrected results on hot, dry days. YMMV.
His chart is most certainly SAE corrected, he got a CF of 1.03 on the red pull and 1.04 on the blue pull, it says right there. The temp went up by about 4 degrees while they were tuning.
The result is exceptional and way outside the norm. A lot of people have spent a lot of money on motor work to get 100hp. But I'm not going to question it, I wasn't there and I know nothing about it. I'll just say congratulations! |

I don't know why, but I typically get annoyed with dyno charts that put HP and Torque (at least when using typical American units) on different scales. Is it just me?

My apologies, I was not aware you were referring to the SAE values for correction factors. I will attempt to get the 'real' values as run on the dyno, I should be able to run them through Dynojets Run Viewer, and get a screen capture of an Uncorrected run. |
