Timing adjustment and dyno run

well got it on the dyno for a couple of pulls 4 and 5 gear runs 74.94 and 82.50 and im lean at top end 3700 13.55 and all the way to 6000 14.06 time for a 200 main im at 195 now low end im fat might have to try another needle or heavier spring when i wack the throttle its dropping down to 10.9 the slide is openning to fast or the taper is a little small. all in all it made good power and torque and for a 1450 it pulled to 144mph running on the lean side not unhappy. ill rejet and try it again timing seems very good and im on the lean side and still no ping!!!

Nice!

82.50 torque went 144 mph on the dyno but i was on the lean side i pulled it to 5900 cuz it was getting to 14.8 .

still the cv cowboy!!!

i want to get this carb perfect as can be then im gonna try the iso performance carb . when i know this carb is jetted just perfect . i will duplicate the set up on the iso performance carb and try it . i was going to put the aftermarket on and try it with the cv kit . but i have the kit in this carb and im rich on first wack and lean on the top end so i gotta rethink my carb set up then illl duplicate . im on the needle for just a bit then on the main for the rest of the pull so ill play with it after octoberfest regular riding its just fine just like to know at wide open that im not to lean at 3200rpm at 80 im at 14.2 .14.5 so im ok for fuel economy and roll on it stays aroun 13.7 13.6 thats just fine and lean motors have a crispy throttle reation any way it aint running hot im cool with if it was not happy it would not have made that torque

gotta go have been waitng almost hour and a half to take the wife out for dinner now shes ready see ya! bout time

dyno sheets you can see the major drop in torque and horse power were it was very fat then it starts to pull as it leans out . keep in mind guys this is in forth and fith gear with a load on the motor as well. i wanted to make sure as i was putting advance in it would not ping and the pulls were from very low rpm

Can't really see the charts that well....But are you adding the timing as you are making the pull or is that not possible??? What did it do without adding the advance??

the advance was in it when i did the pull and then i add more the last pull was when i got the most torque out of it 82 .50 . the pull before it was like 76 so it pick up quite a bit of torque almost 6 lbs it likes the timing im at like 67 foot lbs at 3500 thats very nice and it pulls from there thats great passing torque for a 1450 twin cam. all right back to work see ya. i did my pulls luggin the motor from 1500 to 5900 in 4 and 5 gear so the slide was jumping cause i was at wide open from 1500 to 5900 thats why its very fat at low rpm , chances are that true riding going down the road that is not happening but know one even said any thing to me about it . i dont think the guys like me to much on the fourm .? i think they feel im some kind of smart ass and im far from it . dont want to come off that way at all but thats life came up with that idea of the slide last night looking at the charts the pulls were from way low in the rpm range . and riding in this morning it pulls like a bear out the hole . spank a 96 road glide on the turpike out the hole like he was standing still he pulled on me in fourth but i had im till then . so it cant be that rich in the real world. it would fall flat on its face . you cant duplicate what we do riding on the dyno but its a great tool for wide open and hp and torque readings and air fuel at constant rpm . and if you make changes you can see if its good or bad ya know ?

i cant even kick a hornets nest and get a reply !!!!! when you guys read the post can you tell me if im on track with the slide . as far as it comming up to fast

I know exactly what you mean by this. That is why I don't live or die by what the dyno says. You explained this very well and is a good example. In "REAL WORLD" riding, you spanked a bigger engine with what the "dyno" basically said was a poor performing set up. Here is the key I think, and you and I have mentioned this in a different format, is that when you are going down the road, you are forcing more air in the engine. Much like a "RAM AIR"set up on a big ass Hemi. When you are on the dyno, the engine isn't bringing in the air that it does when you are actually riding.....JMO

i agree with forsing air in the filter as well and the fact that im also bringing the motor up in rpm and not lugging it down in 4 and 5 to see if it will ping and then pull to high rpm . im also not wacking the throttle in 4 gear while luggin the motor on the street . should have done a pull from 2000 in 3 gear and then looked at air fuel . i kinda tuned for mph and ping . dont have all the time in the world to play when someone lets you use thier dyno did not want to wear out my welcome . any way i would still like to know about my thoughts on the slide from the gray beards out hear . they have alot of knowledge about carbs on these twin cams evos and sportys .!!

thanks hrk ! its still the rineharts and i started the pulls from way low 1500 . so my thinking was that the slide slid all the way up and the pump squirted at the same time . she never fell flat on her face on the dyno she pulled strait up slowly . just that big dip was there were it was flat rich 10.5 it dont act that way at all on the street but i dont lug it . never had a carb bike on the dyno and never had a dual set up on a dyno myself seen them on there seen the sheets but then again no one at the shop had done advance slopes on a daytona twin tec unit before and has done what i did on the dyno . so will all learn something new on sat . i also had both pipes on the sniffer as well.

30 percent load on drum and I went up in rpm till i got to 4 and 5 then let it drop back down and then restart the pull drum was rolling and only two pulls the rest were for mph
