i want to by the heavy breather for my 09sg but i cnat afford the pcv yet. the dealer said that the HB will require a map but if i dont get the pcv right away, how should i expect my bike to react?
will i only lose power or am i potentially hurtin the bike?
can i f@%k it up?

 

If you've added pipes, and are now adding the heavy breather, you are potentially harming your bike without a tuner of some sort. Don't do it.

 

Not sure on the tuning aspects of it, but if you haven't bought the heavy breather yet I have one for sale. With my height and floorboard position my knee bangs on the damn thing constyantly. Let me know.

 

+1 Stro1965, check out Fuel Moto's website (Site Sponsor). They will set you up, so save until you can do it right.

 

if the op isn't interested, what would you be asking for it?

**edit** never mind, just noticed that you have an 09 so it won't fit my 07...

 

If you add a pipe and the heavy breather you will be running too lean. Wait until you can get it remapped.

 

I installed Fuel Moto's setup with the PCIII, A/C, and Rush mufflers when I bought my bike last year. About a month ago I removed the PC to see what would happen. I honestly cannot tell the difference in performance at all. There are people that will tell you that you will hurt the bike by not running a fuel management system after changing exhaust etc. but I do not believe it. My bike runs great! The bikes computer can compensate for these mods. A PCV will allow you to run richer than stock which will help the bike run a little cooler. This is just my humble opinion and I am sure you will get many varying ones.
