Vance & Hines pipes installed, possible remapping recommendations.

Hi,

New to the forum and recently installed vance and Hines staggered slashcuts to my 2005 m800 (which sound amazing). 
I've had a look through the site and can't find anything in regards to info I need.
The problem I have is that when I ease off the throttle, I'm getting a lot of backfire. I've been told it may need 'remapping'. 
I have looked on the V&H website and they recommend their own 'FuelPak', although I can't really get much info I want about it.
Does anyone have any experience with this and/or recommend better/cheaper alternatives?

Thanks,

Chris

Hi Chris, Try blocking the "pair valve" first to see if that stops it? there'll be a thread on it somewhere in the fueling section.

I followed Moccs instructions as far as Option 2 - cured pretty much all of my back-fire issues.  Didn't bother removing it completely - looked like a complete pig to go all the way.  I did end up having it Dyno tested, which was one the best £60 I've ever spent

It will be the sound from the unremoved pair valve. You only need to put a fuel injection module on the bike if you have or will be adding a hi-flo air filter such as a K&N at some point.

Cheers for the info,

Will have a look at blocking it on the weekend (unfortunately got a busy week in work). Hopefully the neighbours will get used to the noise soon as well. One didn't seem too happy when I pulled up with the new pipes on.

Congratulations - you've just found a new way to win friends & influence people !!!!
