Jasper, MO | It lets you advance or retard the cam timing in relation to the crankshaft. This will allow you to move the torque curve produced by whatever cams you have up or down the RPM range. The net effect is to improve low end torque (advanced timing) at the expense of high end power, or improve top end power (retarded timing) at the expense of low end torque. You can move your torque curve up or down about 500 to 700 RPM. The torque curve itself won't change much--just the RPM range it works in.
I have not tried these on my Victory, but I've used adjustable timing gears on cars before. These work the same way.

Does anyone know what this does? What are pros and cons? Anyone tried it yet.? http://www.lloydz.com/store/item_view.asp?estore_itemid=1000125 ? ?
Any feedback from any Visions that has it installed??
Is it worth the $$ if you have the following installed as in my signature?? |

Gainesville Fl Home of the Gators | With the gear set at 4 degrees advance; on my dyno I saw a shift of the torque curve of 700-1000 RPM to the left. Really wakes up the bottom end of this engine |

I really like the top end rush I get now with cams, intake, VFCIII, and Lloydz ECU. More bottom end would also be good, but I'm not complaining about what I have now, as it feels pretty much like it did before the mods. What does the top end look like now? I'm assuming it also moved left. Did the HP at 6400 RPM go down about 12 to 15 HP? I shift at 6000 when proving a point. More low end would be good, but I can't afford to lose anything at 6000.

Any increased detonation or ping from doing this? Higher octane requirements?

Sand Rock, AL United States | so this adjustable timing system would be good for a Vision pulling a timeout camper trailer? |

Sorry to belabor the point, but was that 2 HP loss at the peak or at 6400 RPM? I guess I'm specifically asking about the torque at 6000 RPM and the slope of the curve. That's what really matters in a race with a Goldwing. Right now, I've got a better torque curve than a Goldwing except for down below 2000 RPM, which doesn't matter in a race (and the differences down there aren't very much anyway). From 2500 on up to 6400, I've got them beat. In a dragrace with a Goldwing, the range between 3800 and 6000 is what matters due to the gearing of the two machines, the torque curves, and the RPM drops between gears.

Gainesville Fl Home of the Gators | Peak came at about 5600' and carried across just like stock timing. HP curve looked pretty much the same; just an RCH lower |

I already get a little bit of ping in the heat of summer, 6th gear, uphill, pushing a headwind, until I get to 3k rpm. I may have to pass on the timing gear advance. |

New Orleans, La, | Hey Turk, care to elaborate on what performance mods you already have in place? I'm considering a warmed over 106 and this timing thing intrigues me. Can anyone here con firm or deny that Lloydz reflashed ECU has changes to the timing tables within? I have one and I suspect something with the timing tables was manipulated and in order to make an informed choice I would like < if confirmed, what ws done/ HELP! |

Peru, IN | V92SC --- I'm guessing Turk was being sarcastic. Those conditions he described almost guarantee pinging on almost any bike. All he left out was "and pulling a trailer".  |

| .. AND pulling a trailer! 
As for the 2500rpm restriction on using the timing tables in the PC-V, I don't recall seeing that anywhere. My PC-V lets me modify the same range of cells as in the fuel tables. However, having experimented a little, I've found that practically any ignition timing change is detrimental to the performance of the bike for daily driving. The timing gear, however, does intrigue me. It's not changing the ignition point in relation to piston travel, instead, it allows cylinder fill slightly earlier in the stroke.... so... should work pretty well depending on the current volumetric efficiency of the cams being used. Only one way to find out.... on a dyno !

| Well, I stand corrected. I was under the impression that this gear was performing cam advance/retard. In actuality, it doesn't... It works by changing ignition timing. While some motors may respond well to timing changes... mine does not. |

New Orleans, La, | Turk and gentlemen of this distinguish forum, maybe I didn't express myself clearly so let me try this again. As always any and all help regarding this matter is sincerely appreciated. My understanding is that the timing gear, attached to the crank, is in fact is for altering the cam timing altering the filling event of each cylinder. I was asking about possible changes in the ignition event timing whether it is massaged when Lloyd does the top speed limit removal and rev limiter points in each gear.Anybody got any solid info on that? Depending on what comes out the timing gear thing may be the perfect complimentary part to the cams and reflash ECM. Hmmmmmm!

Gainesville Fl Home of the Gators | The gear is not a gear. It is a reluctor wheel. The crank sensor looks at it to determin where TDC is. By adding this part you can trick the ECM into firing the plugs, AND injectors; up to four degrees early or late. It is the perfect compliment to a cammed Vic
EDIT: on bikes with ECM from Lloydz. I have found 2 degrees of advance is key with the adjustable unit

Rancho Cucamonga, CA | So, this does nothing to alter the movement of the valves in comparison to TDC, just the ignition timing?
If the PCV will do the same at all RPM's, would this be of any benefit?
Has anyone confirmed the 2500 RPM PCV limit?
Does the PCV control both injector timing and ignition timing?
Can the PCV be set for advanced timing at low RPMs for low end torque and retarded timing at high RPMs for high end torque?

Changes the ignition timing AND the fuel timing. Allows a solid advance without the side effects of higher cumbustion temps and preignition common with simply adavancing the ignition

I could use some help understanding what is going on here. I understand that fuel is injected upstream of the intake valves. If that is the case what difference would it make if its injected a few degrees ahead of the factory setting when the intake valve opening determines when it will be ingested into the combustion chamber anyway? If this was a direct injection system like a diesel it would be understandable. Obviously I'm missing something important.
