Yoshimura R77 Slip Ons

[BUSGO]

The size and volume of the stock mufflers on the Gen2 probably allow the same flow as the R77. Hence the availability as an option in overseas markets.

I am ridding it a bit up in the rev range but not much? I just test the consumption and I'm getting 75klm less to a tank!!

75 km less.
I can't see that as being possible.
You don't have one muffler faulty and blocked solid do you?

you havent accidentally hopped on someone elses bike have u? (Sorry I just had to)

No change in consumption on mine between stock and 77s.

Did you disconnect your battery and reconnect yet as I did?
A very easy test to see if it adjusts the mapping.
Worst that can happen is you need to reset your clock. 😀

Hey Bugso, yeah it sounds like high rev riding but in my case it's not. Maybe I just had bad luck with all the slip ons, but the fuel consumption/distance ratio always dropped. I did bring it up with my local Suzuki dealer on many occasions. Now I've done more work on my latest Busa I've thrown efficiency out the window :) and it feels great :)

Ok I've done a back to back test. Slip ons on 300klm/27ltr. Std mufflers 300klm/23ltr. Same riding to and from work, all highway.

That's one very thirsty busa in both situations.
I get between 320 & 350 from 17 litres. Even two up sticking to the speed limits. Although, I don't live in the city, which would probably explain your high consumption.
