Hi Can anyone help, I am again asking a question, about a bike I am about to buy, the seller says that the Bike is Sluggish, the outlet for the Silencers are Black, (fitted with Viper Silencers) also I have been offerd a Pair of Standard Silencers but the are from a Injection Model, and this on I have been offerd is a Carb Model, Regards Bernard

 

Sluggish could be carbs out of balance.
Could also be that previous owner has added aftermarket silencers AND K&N filter without re-jetting.

The injection silencers from bikes with analogue clocks will be OK on a carb bike.
Silencers from an injection bike with digital clocks will have cats in the link pipes.

 

hi deano sorry for butting in on the post just wanted to ask u i do have a 2007 model injected bird with the digital dash. standard can on at present but want to put a set of race cans on her till i read your reply above about cats in the link pipes of the digital models. does this mean i cant put race cans on my bird then? or if i can do i need to remap or something else to get bike to run good. can i also ask what are the cats forin the cans?or is this a stupid question

 

Yes you can put race cans on to the bike but they will need to have the link pipes too.

The cats ( catalytic converters ) are there to remove harmful gasses from the exhaust.

It is quite common to put carb exhausts on the injection bikes to free up the exhaust and retain the oem look.

You might get away with just fitting the race cans but you will probably get better results if you also fit a power commander or other such tuning box and have it all set up on a dyno.

The big no no is fitting cat cans to a non injection because they don't have a sensor to keep the fueling correct to protect the cats.

 

thanks deano for clearing that up just one more thing u say i can fit the race cans to my injection bird with digital clocks but they need to have the link pipes too, do u mean the link pipes i get when buying a new set of race cans from fleabay. as the originals as u know are all one unit. thanks for your help

 

Yes - correct - you need the link pipes that come with the cans ( some don't come with them and need to be bought separately )

 

thanks can u suggest any nice cans out there

 

I am using DELKEVIC stainless oval stubbies - very light for the price, street legal, nice sound.

EDIT - I am also using a stainless exhaust manifold from an FI bird so they deffinately work with the FI maniflod.

 

thanks again pal
