Another happy Triumph Twin Power customer
We recently procured a one-owner, low-mileage 2014 T100 SE to get my father back in the saddle, after I revived his long-stored 1972 T120. The original owner had a Seattle dealership install an air injection removal kit and Bassani 7B17Y 3.5" silencers. The bike ran well enough, it was modern and smooth compared to his old Triumph, and we were generally pleased with it. It did seem to have low-speed/RPM throttle snatchiness, and exhaust popping on deceleration. After doing some digging we discovered TTP's performance modifications and tunes. We communicated with Mike at TTP and were advised that his EFI Stage 1 Torque Induction Kit paired with their Bonneville/T100 Performance Tune 3 would be the solution to those issues, as well as more mid-range torque and top end power.
We performed the modifications from the kit this weekend, removed the airbox baffle, and installed Tune 3. We are very much impressed by how the bike has benefited from these changes. The low-speed/RPM snatchiness is gone, making acceleration from a stop and low-speed handling easier and safer. Popping on deceleration is gone. Mid-range torque and overall power have improved, and the bike generally feels livelier and more responsive. My hope was that the performance increase would not be too aggressive, as my father is returning to riding at age 70 after having not ridden for more than 30 years--and we did not find that to be the case. The power is there when called upon, but still very much controllable. He's very happy with the improvements as well.
The most daunting task of the modifications was the airbox baffle removal. I read posts on the forum about various baffle removal methods, e.g. the TTP recommended method of removing the battery, mudguard, and right side of the airbox; breaking up the baffle through the left side intake opening; or using a heat gun to soften the baffle, and just pull it out. After removing the snorkel and air filter to see where the baffle was inside, I decided to just go with the TTP recommended method--the least chance of causing further damage in the process. I printed their instructions for baffle removal--along with the slideshow pictures--to have for reference in the garage while we worked. The pictures made identification of fasteners a breeze, and the instructions were easy to follow. The whole process went smoothly and was not difficult.
The Tune 3 installation went by the book--with the exception of the user (Me!) forgetting to delete the two O2 sensor-related engine codes that were stored, resulting in a check engine light once we were done. No big deal, I re-ran the TTP software and read and deleted the codes, and the light has stayed off since.
We can't recommend these modification highly enough. They have resolved a couple niggling issues and made the bike perform better overall. We are very happy with our experience with TTP and their products.
