| I am getting ready to have Lloyds's cams and fuel controller installed on my '08 Tour Premium but am on the fence about the intake plate due to the increased noise. I have S1L1 exhaust and was wondering how much more noisy this would be.
Can it be heard at a steady cruise or is it just when one opens it up? Thanks for any info! | |

Sturbridge, Ma | I hear it but not Bad... I actually like it!
But on another note, I was thinking on doing the New cams from Lloyds, but I was told by them I might need to install new exhaust which I really don't want to do. I have S1L1 and i'm plenty please with them plus I get to keep the Gatlin tips...Curious who is going to install cams? If it's Lloyd's I'm really, really interested how it runs plus any dyno numbers if you get it dyno'd. Thanks! | |

I don't think a new exhaust is necessary. I have Lloyd's VM1 cams, intake plate, VFCIII, and reprogrammed ECU on my '08 with STOCK exhaust. My goal wasn't to outrun sport bikes. It was to outrun the GL1800 Goldwings that I ride with. They could outrun me when my bike was stock, but now the tables are turned. I do not have any dyno numbers for my bike, but when I do a roll-on contest from 45 MPH in 5th gear with a GW, my bike now just pulls away from them and keeps going. They never catch up. The GWs will top out at 130 MPH. My Vision will go faster than that, but I can't say exactly by how much. The GWs stay behind me and quit, so I do to. Maybe a different exhaust would produce even more power, but I'm in front of the GWs with my nice quiet stock exhaust (which gives away no secrets), so I'm happy. My bike looks and sounds stock. It's fun picking on unsuspecting Goldwings, particularly those who always end the parking lot bike comparison conversations with "Yeah, but my six cylinder Goldwing has a lot more power and is faster than that V-Twin". 
If anything, I would surmise that my stock exhaust, and probably your S1L1, probably produces the best low end and midrange torque numbers with Lloydz cams. A more opened up exhaust "may" make more peak horsepower at higher RPMs, but at the expense of low end torque. I am speculating about the Vision pipes, but I do have a past history of racing sport bikes and even had my own dyno back in the 80's. The loud aftermarket pipes, if they made any actual increase of power at all, always made it at the higher RPMs, and at the expense of low end torque. On those sport bikes, we would just change the gearing to run at higher RPM to take advantage of the modified power band and to compensate for the lowered low end torque. On a 900 pound touring bike, low end and midrange torque are more important IMHO, plus I like the stealth factor of a stock sounding and appearing bike.

SF Bay Area | Here's the deal... when they (the DOT) measures a bike for noise output they measure everything, exhaust, intake, chain, tires, etc, and the total decibel output measured at a given speed/rpm/distance. The intake system on all stock motorcycles are designed to quiet the intake noise, doing so allows a louder exhaust. The sound of exhaust is a better sound than the intake sound. What you need to determine is what kind of performance increase you are wanting from your Vision, and what amount of refinement you are willing to sacrifice in order to get this performance. Yes, all upper airbox filters make more intake noise than stock, I found the Ness top filter make less noise than Lloyds, but both would work very well for the intended purpose. I am a big fan of Lloyd's engineering, he make excellent products. I happen to have the Ness top filter (I live close to their dealership in California) and find that I only notice the intake noise when standing still at idle, my Atom Bombs drown out the intake noise while riding. The noise is a sacrifice I am willing to make for the increase in performance.
My bike currently has the stock MAP, Ness filters, and Atom Bomb mufflers. Bike runs well, I got on the freeway and was stopped for over 125 in the standing half-mile (oops). I have a Lloyd's VFC III in the saddlebag,awaiting installation... there goes my license!

I only hear mine when she opens up.
On the intake plate, I only hear mine at idle, I do not hear it when giving throttle.
There are metal butterfly like things in there clicking at idle. They stay in an open,
non clicking state, when giving the throttle a crack. That is my theory anyway.

Sturbridge, Ma | Ronnie, awesome! This might have been the best response I've gotten!!! I will most defnitely do the new cams Lloyd is coming out with and have him reprogram cpu and dyno when he comes to Mom's in Foxboro, Ma or maybe take a ride to he's shop which is just two hours from my house.
Is only about 3 hours for the whole job plus dyno.
I guess I will have to see how fast i want to go? I also ride with GW'snever tried to race one another as I'm looking for the power when I need it! lol | |

| Remember that he usually has a wait for the cpu's. The old send him yours and wait for it or another to come back to you.
Unless you make arrangements with Lloyd well before hand.
I was lucky enough to have him swap mine out at a dyno event in NH last year before they got popular. | |

Jasper, MO | Good point Rick, about getting in line for the ECU. I waited a long time for mine. They are very popular. It would have been much faster to have just sent mine to Lloyd for reprogramming.
The reprogrammed ECU was the icing on the cake. Before it arrived, ( I already had the cams, intake and VFCIII) I could pull the Goldwings up until my stock ECU rev limiter shut me down at 120 MPH, then the Goldwings could catch and pass me. Now, with the addition of the reprogrammed ECU, which changes the timing in addition to removing the speed limiter, the bike pulls even harder than before, 1st and 2nd gear are extended quite a bit, and the top speed is somewhere north of 130. I now think that the reprogrammed ECU should be one of the first things someone wanting more performance should do.
Here's the difference between stock Vision ECU vs Lloydz ECU vs GL1800, expressed as MPH at the rev limit in each gear.
Goldwing
1st 43
2nd 71
3rd 97
4th 123
5th 151 (theoretical, based on gearing)
Vision, stock ECU
1st 38
2nd 60
3rd 80
4th 98
5th 122
6th 145 (theoretical, based on gearing. Stock speed limiter holds you to 120 in 6th)
Vision, with Lloydz ECU
1st 45
2nd 70
3rd 92
4th 114
5th 142 (may be theoretical, based on gearing)
6th 169 (definitely theoretical, based on gearing)
As you can see, the Lloydz ECU saves you a shift in a quarter mile drag race with a Goldwing, and lets you match the speeds in 1st and 2nd, where you were hitting the rev limiter before, and having to shift, losing a lot of time. If you get these mods done, shift at 42, 65, and 85 (6000 RPM, to stay in your best power band), then hold it in 4th through the end of the quarter mile.

San Antonio, TX | rdbudd,
Great post. You need to put that in the Tech Reference forum! | |
