    Running Zeros

    Hi Guys - Its been a while since I have been on here but still I'm riding my Meanie.

    My question is about riding the Meanie with aftermarket filter and pipes with the fuel controller set at zero/ no fuel controller - I know a while back a number of people on the forum claimed to be doing this and I was wondering if that was still the case and if there had been any long term problems with doing it?

    I have had a PC III on my bike for a while which seems to make it run rich and not add much to performance , my insurance provider wants to load my premium for having one so I have decided to take it off as I don't think its adding anything- I'm just a little concerned it will run too lean.

    I don't have access to dynos so that is not an option ( If I did I would have tunes the PC III) and I do remember a number of folk on here talking about running zero.

    I am running a 360 K+N car filter( Cadman style) on the RH side (cross over removed) and cut down V&H longshots.

    Thanks for your help

    No one willing to offer an opinion ? Its not legally binding you know - I just remember lots of people in the past talking about zero setting on the PC III and wondered if they were still running zeros and the valves hadn't melted !

    Lots of views but no opinions it seems

    Personally I have never understood that people are using PC III and running it with zero map - and then telling about the positive effects (one has better mileage, one has better throttle response, one has better acceleration etc.). I still cannot understand, because just using zero maps means that PC III is not changing anything in fuel map.
    If there are some other features which might be used while using zero map, then it should be definitely mentioned because it is totally different issue than "just using zero map".

    I do not mean to be rude or anything like that to anyone, I'm just wondering

    Seven Exhaust Systems for Kawasaki Vulcan 1500 Mean Streak Motorcycle | Motorcycle Cruiser

    In the article you can read about the influence of different aftemarket exhaust systems on the AF ratio. I (we) don't know what your system is doing. Anyway - for tuning you would need the lambda readings.

    My Streak has a K&N air filter but stock pipes. I do not run a PC or fuel manager (= zero map) but rarely turn above 5000 and hardly need a high-speed enrichment the pipes mentioned above need. Indeed my Streak seems to run a bit lean up to 2400 rpm (IMO not due to the filter mod). To make a long story short: my valves have not melted yet.

    PS I'd rather be concerned about the pipes than the filter (as for lean condition).

    My hundredth posting goes to......Jarmoke, Finland: You are not alone.

    The unmentioned feature is the accelerator pump function of the PC.

    I borrowed a pc3 once and put it on my Voyager. It tanked my fuel economy with no noticeable change in power or operating temperature. I returned it and now keep all my bikes stock.

    That's probably best when you're clueless and have no skills.

    I've been running a zero map for about 3 years now, mainly because I'm to lazy to remove the PCIII, I am using the accelerator pump feature on it and that seems to make the initial deliver when I grab a handful of throttle a little quicker. I like many others, couldn't get it to quit running rich with the PCIII.

    I didn't realise this was going to turn into a ***** Fest !

    I do know about the Accelerator Pump function - I was running it when I had the PC III connected.

    I also understand as with most bikes that one mode ( either pipes or air filter) doesn't need any fuel management - so I was most interested to hear from people running stock fuelling with aftermarket pipes and filters. I am running a pancake "spectra" filter (like a K+N) attached to the RH side into the throttle body and my pipes ate cut down Vance and Hinnes Long shots.

    I think I will be keeping the PCIII on ( putting it back on that is !!!) and turning down the fuel down a bit across the range - not exactly scientific I know - feel free to **** your pants about that but remember if your known to be a serial knob on this forum I probably wont be able to see your comments so save your bile for someone who gives a flying **** !
    To all the others who posted helpful comments - thanks , still seems a bit of debate on if we need a fuel controller but I guess slightly rich is a lot safer than running lean and hot on long runs.
