Exhaust mod!

 Hi guys, you may have seen I asked Mick to explain his exhaust mod as I'd not heard about shoving a 'Zulu' spear up your stock exhaust & hitting it with a sledge hammer    , joking apart it doe's look a little brutal :aghh: . Would it be ok to carry out this 'delicate procedure' to my fuel injected M800, would I need the ecu re-mapped or would I have any problems resulting in doing this mod?, I've read all posts & been on utube, I think I just want re-assurance that all will be ok  , I think I'd rather just pierce the 2 baffles first & hopefully not drill the end plates, as usual all your comments, advise & knowledge will be much appreciated     

Hi John, I 've been thinking about this one to on my 2002 VL.  I'm just down the Road from you and will be following this thread to see the Answers you receive.

It'll be fine guys, Hammer away!    Don't forget you'll need a pair of grips to twist the bar round to release it, I used a 19mm masonry bit in my sds drill which is equally brutal but requires less effort.

Simple rules are these on fuel injected vl800s:

Higher flowing air file, no problem.
Higher flowing exhaust, no problem.

However if you mix the two, you need a fuel injection module added.
I know that some have said in the past that they still have the stock exhaust so it will be fine to add a higher flowing air filter but if you tamper with the exhaust. It is in affect making it higher flowing so will need a fuel injection module if. One or the other is fine, no fuelling changes required, but not both any how you do it.

Hiya, I have the fuel injected model and have no FI light lit and no problems with how she starts and runs, I used drawn bar which is smoother and sharpened it in a lathe so it needed hardly any effort to punch the baffle plates or to pull it out after the poking process. I still have the rod of desire if anyone is local and needs to borrow it. Get clubbing away, you will not regret it!

done this mod on my carb bike all is working ok not drill the end plates to date
