Hello, I have a 2010 RK with Fat Cat, AN Big Sucker, and a Fuel Pak. If I put cams in this bike such as a SE 255 or something else (I hear good things about the Cycle Rama 575) will the fuel manaement have to be changed? I have heard that the Fuel Pak will not work well with aftermarket cams. I sent an email to V&H and did not get a response. Any info is appreciated.

yes if you change the cam everything has to be redone.

Get the TTS Mastertune or SE Super Tuner. You won't be sorry and the results will be pretty dramatic from a relatively stock bike. I went with Andrews 37H cams, PM SUper Gas A/C and Rinehart slip ons. After some tuning I was able to eek out 65HP/95 Torque, pretty good improvement from OEM IMO!

 

When I put the 255's in my 96" I also had the Fuel Pack. I too tried contacting V&H and got no response. Ended up ordering a PC-V w/auto tune from Fuel Moto and had them base map it. That set up ran so good I never did have it dyno tuned! In fact, that set up ran so good, my wrench thought I was crazy to do my 103", Andrews 54H & Big Boyz heads build!

 

Thanks guys - that is what I was thinking (have to dump the Fuel Pak and retune). I wonder if a PCV without auto tune will also work?

 

Yes it will but, you may have to hook your computer up to the PC-V & do some "tweeking" to the base map. My "base" map was not perfect and the bike stumbled off idle till about 3000 rpm. Within a couple hundred miles the auto tune worked all that out. I'm not very computer literate and didn't want to mess around with all that. Jamie & Keith at Fuel Moto were very willing to help & told me to give them a call and they would walk me through any problems I had! Luckily, I never needed to!

 

you don't need auto tune if you have it tuned on a dyno.

 

Yes. You need a fuel management system that will allow timing adjustments; the Fuel Pak will only add fuel.

 

Well I should have spent the Xtra money on fuel Mgmt to begin with. How much for the PC V plus auto tune?
