Awful backfiring.....

[Locky1935]

Im looking for some shorter slip on slash cuts for my Roadster, if you you tube roadster slash cut theres some which look exactly like the stock pipes but finish just near the rear spindle instead of near the number plates...any ideas/suggestions ??

I have these on mine...sound good, no cat. When I replaced collector pipe with boxes for one without was when I needed the tune for popping. Was not backfiring when I just did these slip-ons.

I bought and fitted those pipes to my Rocket X. Had to get them ceramic powder coated first. Took the bike to a Dynojet tuner, who did a great job tuning the ECU. It has the occasional 'bang', which I've been told can be tuned out by adding fuel.

In Brookfiield Connecticut USA at Dyno Solutions. Great story....guy left a large company building dyno machines....built a portable building specifically designed to house Dynojet machine...he spent over an hour adjusting each gear a fuel mixture at rpm band in 250 increments. He charted all restrictions and printed the engine metrics...will decide later what I want to remove in what gears later.
Can't believe the difference....on ride home fuel consumption went from 25 to 35 mpg....torque and hp improvement was very apparent. Best of all, I could downshift without people thinking there was a shooting in progress.

Dyno is the way to go.....now just have to avoid temptation to unleash what the factory has done to protect us from ourselves! At that price I plan on doing an annual spring check-up

Do it! Have him open up the Secondaries

interesting read on decel popping

Popping during decel is the right way for a motor to be tuned, otherwise it's just wasting fuel.
