JARZ does it again, playtime soon

JARZ does it again, playtime soon

That's on the 131?

[cold1]

      yes 131" R&R Cycles 

[porthole]

Had the bike in for a new rear tire. My dealer has a "100 HP Club". basically something they started to generate interest in work and paying for their dyno when they got it.

So I had them do a run to see what it looks like. Don't know what it should be, but was disappointed to see it did not break 100. It actually just barely broke 90. 90 - 94.

That's not shabby....what were you expecting/what was it before?

[porthole]

1st time on a dyno Spyder. Not sure what to expect.

Thought it would have broke a 100 though - with cams (S&S 570 gears), compression, larger intake valves and head work, roller rockers, minuscule piston increase, .010" over.
Tuner is an auto unit from Revolution using O2 sensors. Probably not the best tuner, but I'm tired of trowing money in the bucket.
Even threw in some Octane booster that I had.

The good news is - three full throttle runs from 2200 to 6000 and the dip stick stayed put

Not bad, remember all the mountains you've climbed.  har!  spyder

Dwayne I think something is awry with your motor.   That combo should be making 108/115 plus or minus 5 depending on throttlebody and exhaust.   I know of at least 7 of these locally and the worst of the numbers in HP is 103/118, but he has a small throttlebody and restrictive exhaust.  Its a 03 CVO RK.

Before getting to far down the road you might want to be sure it is not wet sumping or off a tooth on the cams?   You may also consider doing a cold cranking compression test and leakdown.   

These are  decent numbers for a stock bike with open air breather and exhaust and even a little low for that.   when they did the run did they do any runs with the sniffer in as well to check your A/F for you?

[porthole]

Harry, just a run for HP and T, no sniff - its a dealer thing. One hour, couple of pulls, give you the print out. Wouldn't trust them to do any tunes anyway

I agree with porthole,  it also says it was over 90 deg.  And I don't think they check airfuel ratio either cause your bike is running very lean.  Smooth line across the bottom.   Wonder if the machine has been calibrated?

Tweeter why do you say the bike is running very lean, just curious how you came to that conclusion from this dynosheet? 

[porthole]

And I don't think they check air fuel ratio

Not checked

[tweeter13]

The graph across the bottom of the dyno sheet,  it was a smooth flat green line around 18:1.

That's very lean if the sniffer was plugged in to the tail pipes.  I would think if it was that engine would not last very long.

That is a default when no sniffer is used and they print the A/F table with no data
