First, I just want to get it out there: I know there are better fuel tuners, so please don't turn this thread into a lecture experience on all the other systems that are available.
My son bought the Fuelpak for me as birthday gift so I'm trying to make it work.
Here are my particulars:
2013 VRSCF Muscle, K&N Filter (top 'on'), V&H Comp slip-ons.
Fuelpak Model #61021
Tried running the provided map #4690 with the following results:
1. Black, sooty smoke under hard acceleration (witnessed by my riding friends)
2. Sooty build-up on baffles of both cylinders
3. Cruising at part throttle on or around 4K RPMs, bike will occasionally sputter and backfire (not to be confused with a lean pop)
4. Bike accelerates hard through to redline without hesitation (except for the black smoke mentioned above)
5. Bike stumbles, hesitates, sputters on or around 5-5.5K RPMs in any gear.
6. Starts/idles fine
7. Throttle response at low speeds is very abrupt - it acts more like an on/off switch at low speeds/low RPMs.
I already know all of this means it's running rich. I've been on bikes for 37 years (and do I 'know' carburetors!).
I've been in contact with V&H and they provided me the following adjustments to Map 4690 (I haven't had a chance to try these new settings out yet):
(First number is the Mode #; Second value is the Setting)
1:6
2:5
8:15
9:8
10:10
11:16
15:18
25:12
26:15
My location is near sea-level and daytime temperatures run anywhere from 40-90F (5-40C) throughout my riding season.
I am calling out to other members with this same set-up and especially those who encountered some of the same symptoms as me. If you received or otherwise modified this base map on this model based on your own experimentation or V&H technical help, could you chime in please.
I'm a bit frustrated as the bike is more ride-able with the OEM filter installed and no Fuelpak (i.e. factory 'lean' with just the slip-ons!).
My thanks for any of your time taken to reply.
(Just an FYI, I'm away from the bike on business for the next couple of weeks so I won't get a chance to field test anything provided to me until then).
