First Dyno Pull Ever!!!

Re: First Dyno Pull Ever!!! AFR CHART

Here are my AFR numbers for the dyno pulls...

awesome take it all in and learn alot while your there!!!:rocket_bike::cheers:

HRK and BP, I forgot to mention as well that my indy does not think that my air intake is restrictive. I just wanted to say that we live about 30 miles from the company that designs, flows and produces the system that I have. My indy knows the people really well and I have been there many times myself.

Just thought that I would mention it. My system sucks some massive air. I can hear it as I am riding. It is really neat too when I shut the bike down you can hear it just release. If anything, I could be sucking too much, with this set up. One could make that argument and have solid numbers to support it..

what intake is it that you run jb ? shoot me the link to my email please thanks

Hey BP, did you take a look at that whole site??? http://www.dmcustomcycle.com/product_list/Boss Series

hes got the needle shimmed so it comes in way to early in the pull . if he was to drop the needle jet back to the stock setting in reality it should be closer to the high 13.0 the fact is from what i see in the run is at about 4000 he starts goiing lean if he is tunning for power he should be at 13.5 13.2 across the pull if he was to bump the main drop the needle to the stock setting he could get there . but with the needle shimmed were pissing in the wind . torque is gonna come up for sure if he puts more ox in the fire . im still not happy with the size of the pipes big pipes flow volume but very slow and you got to feed them lots of fuel to get a good ride feel . its a give and take with big pipes they make power up top . suck ass down low . we will see when he gets a good tune in it . he has all winter to mess with it lets see what he comes up with with his tech seems he has a handle on it . and a great deal to boot !!!!. i would like to see it drop no lower then 12.5 at the start pull strait at 13.5 across the rest of the pull .

Everyone does realize that these numbers are based solely off of a 3rd gear run? when I am in 5th, to get to that rpm, I would have to be going what, 90-100 mph? I am not in that rpm range that often... Just saying... Or do these numbers change from gear to gear?

numbers will change . it takes less fuel to maintain a speed at throttle in high gear once you get the mass rolling . lets say for example at 70 miles per hour in lite wind it would take 20 horse power to cruise at 70 miles an hour and keep it there

Ok, I understand that it looks rich down low in my RPM and then it start to lean out, but isn't that just indicative to gear ratio of 1st gear? Who cares really what my pilot is doing because I am not there long enough for it to matter? Also, would moving my baffle closer to the head compensate for low velocity that I have now??

well my freind i dont think the dyno operator took that reading in first gear . the way its done is you shift till you get to third . let the motor come down to the rpm you want to start the pull at . hit the sample button and roll on the gas and do the pull till you get to max rpm . just saw the pic of the bike nice ride dude . i dont know what to say about the pipes they look real cool . dont know about the performance end of them . if you dont know my moto is keep your mouth shut till you do ! steep bend and big diameter and short pipe? moving the baffle towards the head will restrict the flow some and increase back pressure .

thanks. I didn't get to see that part of it since he said that I couldn't be there. he was busy with other things as well. Chat at you later, gots to go work. then what is the concern with my pilot all of a sudden? I have my idle screw out 2 1/4 btw..

The torque curve looks pretty flat. What indication do you see that tells you the pipes are killing the bottom end. Wouldn't there be a dip in the torque curve if that was true? Just askin.

I gotta find a pic of his pipes, I'm not sure what he has.

I would love to see a set. Of Bubs on there

Ok, I found a pic. Nice customization Johnny.
Those pipes are short and duals so they are a drag pipe of sorts. Good for top end prolly 4500 to 7000 grand WOT.

But the WOT torgue curve should rise but it is flat so now I see he has other restrictions at the high RPMS. Ok, I gotcha, I think. I'm a bit slow

Thanks for the compliment Tom...

HRK, I will get pipes for it. Hot Rider will let me get the Bassani's. Remember, I can get a set of Bassani's through my dealer at pretty big reduced price as well. I want to see what it is that I can with these pipes before I do that though. I guess because I am a pain in the ass and don't listen all that well all the time...

I haven't said crap about porting heads or cams since I put my bike on the dyno. Once I get my needle and other jets in, I will do what it is that you want. I did have a smaller pilot and I coughed and sneezed all over the place, but I will do it just for you. I am open to learning. I may be stubborn, but not stupid....

Are those AFR charts without running the V-Ductor?? Runs with the V-Ductor seemed to lean it out,comparing the sheets,but you can't really get any numbers from the sheets
Are you going to use the V-ductor or no?? If those charts are without it,see if you can get a chart with it...regardless, I think you gotta loose the shim and get a set of go pipes instead of show pipes...

Correct me If'n I'm wrong but weren't some of yer last words you don't believe in Dyno tuning ?

And correct me if'n i'm wrong but wasn't somebody talkin to you about Pipes are either for performance or Looks.
Now look where yer at and what you've ran into.

And like HRK stated, is this in SAE or Standard and what kind of dyno machine was it done on .
