Need help - removing exhaust valve

Hey

I know there are posts out here for removing of the exhaust valve but I cant find any. I know how to trick the FI light but I need to know how to remove everything and tie off the valve.

Any help would be greatly appreciated.

Cheers

curious too, I believe peeps have been manually fastening them in the open position with wire or similar.

go down to the valve and pull the cover off, i believe its two 8 or 10mm bolts. unhook the cables and put the cover back on.

next pull your seat off, unbolt the servo motor and take it out. then follow the writeup for the wiring to trick the computer. its really easy.

cool. I thought I had to use wire to hold the valve open.

Yes, I figure there should be something good installed to hold the valve open.

I have been looking at the valve and spring assembly for a while (bike is just going back together for a track bike). I am thinking of making a small bracket which will fasten the centre flapper valve bolt/shaft to both the small bolts where the cover bolts on. I believe the spring does not have enough tension to stop the valve from rattling or changing its position from wide open.

Some wire would probably also do the trick too:)

no need to put anything on to hold the valve open, once you pull the cables off the valve it stays open full time

I did this mod to my exhuast valve and is was held in the closed position with the spring. What you have to do is take the whole assembly off so it is just the valve.... start the bike and rotate the valve to the open or closed position, you cand tell fairly easy by listing to the exhaust note. and mark it. If you marked it in the closed position rotate it 90 degrees. I saftey wired mine open by drilling a hole in the case and attaching it to the valve and the hole in the case. Then to delete the servo motor go here.....Decided to fix the servo removal problem for you guys *Quick and Easy FI Light Fix*
