Been running regular 87 since day one, with no issues whatsoever.

I probably live around the corner from you
The other reason I stay away from 87 is that pretty much everyone is blending 10% ethanol in their low and mid grade. The only way to avoid ethanol around here is Ultramar super, Stinson super, Petro Canada 94. I've always thought the slower burn of higher octane fuel results in a slightly cooler burn. But then, our bikes are soooo lean that it probably makes no difference at all. |

recently switched to 89 with no issues for 3-4 tanks. My nomad does not have neither a knock sensor nor an O2 sensor.
Ordered spare Throttle body off ebay for more research. Looks like there is a intake pressure sensor on the bike, however it is only hooked up to the rear intake port. with the imbalance found between my cylinders, I can see why the front was running lean. With MAP systems in cars, a drop in vacuum indicates an increase in airflow, requiring more fuel. What I did with adjusting the big brass screws(actually plastic I think) is drop the idle air pressure in the manifold while also balancing the front and rear port. as a result I have a much more balanced acceleration and better fuel economy than new. The ultimate result is changing a bike I nearly regretted buying to one I'm really happy with. |

after my tuning, I plugged my vacuum port extensions together to help with the off idle imbalance. |

Ray and I both use 87 octane with no issues. Even on rediculously hot days 87 has not caused any knocks or pings.

I never heard my Voyager ping or knock running 87 from day one.

My Voyager has only knocked (W/87 fuel) while riding two up on a very hot day in York, PA.
My HD friends say that the bike was just being intimidated by all the Harleys being built there.

I think your differential manometer is indicating a serious intake manifold leak, rather than an out of adjustment throttle body. The manifold can leak air at the cylinder heads, injector ports and at the throttle body.
The manifold to cylinder joint is a bit cheesy, and I sealed mine with Hylomar on the aluminum surfaces, made a world of difference in how the bike runs. I also added sealant to the injectors and installed the Thunder gasket at the throttle body. In theory you may be able to compensate for a manifold leak by adjusting the idle air screws, but the engine will still be pulling unfiltered air past the leak, and the leak gap may change with engine temperature.

First was to check the idle vacuum balance. Using my carb stix there was LESS than a 3 mm difference between the 2 cylinders. Adjusting these even made no discernible difference, but I as most have done have sealed my throttle body to intake manifold junction, and on top of that the junction of intake manifold to the heads, another prime source for vacuum leakage. Safe to say I have no vacuum leaks to have a negative affect. Second I always knew but never gave it much thought that the MAP sensor is fed vacuum from just the rear cylinder, all of the 4 cylinder skoots have vacuum ports on each t/b that connect into a common hose that feeds into the MAP sensor. DUH ME!!! So last night I machined an extra vacuum nipple outa stainless steel, drilled out the throttle body and pressed it in. This extra nipple feeds into a hose which tees off to the rear t/b and both feed the MAP sensor. The one existing nipple on the front t/b bore can be used to accomplish this tie-in, but I wanted to make future checking of the idle air vacuum a bit simpler. Idle seems a bit more stable so I will have to wait until I can ride the skoot to determine any on-road differences. RACNRAY

I've toured that final assembly plant during my one and only visit to York bike week, very cool inside
