hi all
ive got the 660 tenere 2010,brill bike,ive just fitted the LEO VINCE SBK mufflers,and they sound soooo nice but it does pop/backfire very bad when you shut off,so i rang my local yamaha dealers and told them i would like to have it re-mapped and both said,"sorry we cant do it,we have tried to re-map the 660 tenere but we cant,the only way you can, is by buying a power commander,and thats about $600 give or take a $ or two http://s3.amazonaws.com/advrider/bncry.gif

now can this be right,also will this damage the motor in any way if i dont get it sorted out...please help http://s3.amazonaws.com/advrider/eekers.gif

Quite correct, you can not remap the standard Yamaha ECU. If you want to stop the poping back block off your AIS pipe, all details in the mod section.

A Power Commander with a custom made fuel map is the way to go if you have the funds, $600 for a PCV + $250+ for the custom made fuel map.

You do have other choices as there are quite a few fuel mods out there.

Have a look here, might be able to help.

Basically, the AIS is a little valve that when you back off the throttle, opens and lets cold air straight into the exhaust. Because of this, any unburnt fuel in the exhaust will burn up quickly causing a backfire. With the standard exhausts, you don't hear it so much because they muffle the sound, but when you fit aftermarket exhausts you can seriously notice it.

As for damage, no, its perfectly normal and is what the bike is designed to do. If however, yuo don't want to attract extra attention from the coppers from a backfiring bike (which can be quite loud!) then block the AIS off.

Enjoy your shiny new bike :023:

You are fine to run just the LEO VINCE, if you are going to add filters then I would recommend a fuel mod.

The AIS can run at anytime & works quite a bit on the cruise, so block it off & enjoy, block the pipe as I have shown in the diagram.
