Free flowing mufflers

[Kapiti kiwi]

Hi guys 

so I have some staintune mufflers but sadly they are dented badly from prior storage I’m guessing 

I have a local motorcycle mufflers shop nearby ‘cycle works” 

I also have some other no name mufflers in black but they are very open or free flow with removable baffles my question is if they are to free flowing what do you have to do to correct fueling is it that CO trim I’ve heard about 

bike is has crossover pipe as well otherwise stock

I’m in two minds,about getting staintune mufflers repaired ie re skinned or get cycle works to make new link pipes for these black mufflers as my bike is basically All Black now bar pork chops and bars for now

If you can get the ‘Toons repaired it will probably be worth it. A V11 with ‘Toons is one of the best sounding motorcycles ever built.

As for getting it to run right? First a proper tune up, then remapif you feel it needs it.

Fit the mufflers and ride it and see how it runs. Probably won't need to make any fuelling adjustments but if you do start familiarising yourself with Guzzidiag. It's free and awesome for tuning.

The pork chops hold the bike together so act accordingly support wise. Not possible to anodise cast aluminium in Australia or I imagine in NZ either. Rub them back with wet and dry and green Scotchbrite then spray them with 2K paint like I did a few years ago.

I was fortunate enough that the V11 I stumbled into already had Staintunes mounted. And there they'll stay. The dB killers might make suitable cigar holders.
