There is ZERO tolerance on personal attacks and ANY HYPERLINKS to PRODUCT(S) or other competing website(s), including personal pages, social media or other Forums. This ALSO INCLUDES ECU DIAGnostic software, questions and mapping. We work very hard to offer commercially supported products and to keep info relevant here. First offense is a note, second is a warning, third time will get you banned from the site. We don't have the time to chase repeat (and ignorant) offenders. This is NOT a social media platform; It's an ad-free, privately funded website, in small help with user donations. Be sure to see the GTM STORE link above; ALL product purchases help support the site, or you can upgrade your Forum profile or DONATE via the link above.

Ron, congrats on the V7R and welcome to GT.
All of the new models are fueled very lean for Euro emission specs (as delivered). You can likely get away with keeping the stock fueling, however, there is a big benefit in improving the fueling.
While low-speed fueling (only) is crudely adaptive (closed-loop via the narrow band OEM 02-sensor), it will hold the extremely lean set mixture. Higher RPM and throttle position are still static/open loop.
Increased flow to intake and/or exhaust means a bigger reason to revise the fueling, and with it comes smoother/cooler running, and more power of course.
Details on the options here; https://www.guzzitech.com/forum/208/2686.html
This is the equivalent of a jet kit when modifying carb'ed bikes, which people never hesitated doing because they knew the benefit. Nowadays it's more complex and expensive, but it can be done to extremely precise settings (highly dynamic revisions in real-time with AutoTune).
Happy to help you get it sorted when ready, reach me direct e-mail; Todd at GuzziTech.com

Hey,
I been riding my V7 cafe with mistrals, by-pass and no baffles since new (2010) and 20000 km....no reprograming of any kind and the bike is doing pretty good....maybe you would gain something....but if you want something powerfull, small blocks are not the right thing.....
