PostSubject: Exhaust mod!   Sat Jul 12, 2014 11:26 am

 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 affraid   , 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

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!
