    Advent+tuning

    Adding an advent cdi. Currently running one size larger jet in #3 cylinder. With the timing curve change should I run all jets the same size?

    Currently:
    125 pilots
    145 mains with #3 147.5
    1.5 N/S
    95g spring 43 psi popoff
    Maxima 927 32:1 premix

    I bought a used Advent and will probably get it reprogrammed if I ever hear back from adventignitions. The current curves are YAM 76, 44, 45, 46. I am currently using a protec CDI.

    I will be going back to 110 pilots as I am way rich at idle. Maybe changing to 115g spring, too.

    I wanted to know if running the advent will have enough retard timing in the #3 cylinder that keeping the larger jet in #3 carb will be unnecessary.

    Factory Triples
    Riva gas valves
    Prok flame arrestors
    cylinders ported and polished
    stock carbs and reeds

    The only curve I could find on the Advent site out of the 4 you listed was #44. It retards #3 quite a bit but don't know if you could run pump gas with it. jetting #3 like you indicated will help for sure. Who did the porting? They would probably be able to help.

    Some of the tripple pipe guys should chime in on this.

    Yes, I was hoping to try the 44 curve, but I wanted advents opinion on what would be best. The other curves are custom from the guy I bought it from. Advent's website shows this as 92 octane. I run 93 because of the pipes and a 41cc head.

    Porting by IslandRacing.

    So you are saying keep #3 one size larger?

    I would keep #3 a size larger, just from what I have heard. Even though they are individual pipes with staggered timing #3 still runs hotter.

    Advent will give you the curve printout but you have to call them until its done. Don't bother emailing.

    The only reason I would be nervous about running #44 on pump gas is the very aggressive timing at lower rpms. My box came with 60 & 61 wich have simular high end #s as the 44 but 44 is dramaticaly higher below 6000 rpm making me think you could suffer deto at cruising speeds. I don't really know, the only experience I have with the tripples is CC race boats with race gas and MSD.

    Maybe you could get some tripple pipe guys to respond to a different thread heading like " Tripple Pipe Timing HELP " The info is here. Just my .02.
