I bring this on top again (it was "hidden" in another thred) I will have a Dyno test wednesday next week. Do any of you have a dyno chart? As many as possible for comparison. What we need to know is: *K&N Air filter? *Aftermarket exhaust? Brand? *Exhaust mod? Glasspack? Cut Piggies? *Dyna 3000? *Jet Kit? *IS Springs? *Airbox modifications? *De-smog? *Jet size? Did I forget somthing? Please post your Dyno Chart (or email it to me [dve@online.no] if you want to be anonymous)Here is my friend Knut Olav`s 1997 Tourer with Thunder Pipes and Lamonster Supercharger: !!! TORQUE IN NM !!! 174 Newton Meters = 128,3 Foot Pounds  |

Hmmmm. Something wrong with the dyno chart. The dyno calculates horsepower from the measured torque by multiplying torque X RPM, then dividing the result by a constant factor of 5252. So, the numeric values MUST be equal @ 5252 RPM. That is, the curves always cross at 5252 RPM.

Not wrong, we use Newton Meters in Europe.
2520RPM / 125HP and 170NM (125 Foot Pounds)
174 Newton Meters = 128,3 Foot Pounds

98 std, stock head pipes (weld flashing removed/ported) w/thrush glasspacks, stock ICM, stock TW, airbox lid and intake tubes modified, stock airfilter w/metal screen removed, 35 pilot jet, 110 main jet, stock needles, dial-a-jet, intake manifolds polished 320 grit. The spark plug pickup was broken, so no torque reading only HP.  |

Jeff K, I have been lurking on and off this board for about 8 years got sick of computers and tossed mine in the trash in 2004 and wife got me lap top for birthday June. So i am computer challenged  So My kids are going to help me this weekend to post pictures of some projects. kids are in their mid 30"s .What size throttle body are you using on your injection? and did you retain your J tube?. I have lost idler pulley once and made it home safe with no belt because of j tube bypass. Magnacharger ( Bill ) has offered the new upgrade 45 Mikuni w/o J tube some postings i have seen here have been very pleased with the new carb. I installed 45 4 years ago and was shocked at performance increase with j tube port matched to carb. Can you still get home w/o bypass?.Thanks in advance. Ps thinking of buying his new carb manifold. |

Hi guys, Could anyone tell me how should the maximum power AFR curve be on the Valkyrie?
I know the shape of the AFR curve needs to be a straight flat line, but what values?

 2001 std. Aussie model, piggies off,drilled baffles,std timing and ICM First run with 35 pilots,100 mains and foam pad out of airbox, 87 HP Next runs with 38 pilots,125 mains, airbox opened up, 94 HP An easy 7 HP gain. Currently running 127.5 mains as the 125's were still a little lean. Have not been back on the dyno but should be doing so shortly Cheers Blackduck |

I've been told that the blower will spin from the vacuum of the motor and it will still run, but I've never tried it. I'm running a 55mm throttle body now. I was working on a progressive 2 bbl throttle body off of a BMW but got side tracked by life.  |

Found some pics This is what I have on now  This is what I want to use   I had it on for a while but put the old one back on because the progression didn't fit the hp of the bike. I was hoping that I could run on the small bore at cruise, but I was always getting into the secondary. It was a pain to drive. I need to modify the linkage. or maybe find another TB |

Thats cool. The single was 55. What was the duel MM?. I was going to go with 50 mm carb but thought like jetting small steps are easy to reverse. Are you getting any MPG from FI setup?

I was getting 31-34 mpg until I went with the 8:1 pistons. Now its more like 25-27. I really wish I would have stayed with the flat tops. Not only for mileage but for many reasons. |

I had my bike tested today. 1997 standard *K&N Air filter? Yes without prefilter *Aftermarket exhaust? Brand? Yes, Viking *Dyna 3000?Yes *Jet Kit?No *IS Springs?Yes *Airbox modifications?No *De-smog?Yes *Jet size? Stock, 35 slow, 98 main I would think the Dial-A-Jet gives me 8-10 HP I`m not sure home much power the exhaust, dyna 3000 and the air filter gives? The most important to me is not the HP, but torque. I can feel the torque, not the HP The air/fuel ratio tells me I could go down one more size on the main jets.  |

Dag,
too lean in the 3-4k rpm range, that is the needles.
look good on the mains, most engines make max power 12.7 to 13.1 +/- a few points depending on engine. mikuni recomends a jet size change for every 25 F degree change in ambient temp to maintain the same power levels.

Dag, 106 is the top Dog on the Unblown HP shootout so far. The Dyno guy in my area has told me that high 80"s HP is pretty standard for stock Valk and His words he has Dyno"d a lot of them. Just getting ready to put mine up on the Dyno. Riding Season is almost over up north and now is the time to push her hard have all winter to Repair. BTW 99.6 HP -100.6 TQ ( when was stock ) Viking Exhaust--6" Trgger--Dyno jet needles Stock jets. This was done in 2001.

By the jagged curves it would appear you need a jet kit or larger mains.
Had the same sort of curves until I upped the main size.

It is two years since I installed DAJ, and has regularly posted my experience here. I have noticed that here is very little interest of the Dial-A-Jet kit here. |

A buddy with a 2000 Valkyrie, 100% Stock did the Dyno as well.  Here is the result:  Here is a comparison of Air / Fuel Ratio and Torque of a stock Valk and mine with DAJ during a simulated road test  As you can see, the 2000 Valk are running much too lean. The most interesting observation here is the torque and throttle responce difference. |
