Quote: If your exhust is engineered for your bike, did it need rejetting?
I never rejetted. She seemed to run well, no issues with popping. However, after doing a lot of reading on the site, I did buy a set of jets (130's) and was planning on putting them in until my accident. Perhaps it's more appropriate to say the Bubs are tuned for the bike. If you do a little research here, you should find the thread where some others chimed in about the Bubs were set up for the Triumphs. Either way, I was very happy with them.
