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.

this has nothing to do with your post(which was very informative) but do you know what handle bars are on that bike? I need something like that(have constant tennis elbow and need more pull back) and cant seam to locate/identify them.

I also have kind words for Mike and the TTP crew. I just finished a brake upgrade I purchased from them. They were more than helpful. I bought a Pretech 6-piston caliper. It had to be back ordered because I did not want the standard finish, so they had to make me the one I wanted. TTP kept me in the loop on the status of my order and got it on the plane to the US as soon as it came in from the manufacturers. The TTP crew seem to be good people. ...J.D.

BTW: The Pretech caliper is FANTASTIC !

I heartily concur with your assessment of TTPs products and services. I installed the same tune with TORS on my 2014 SE and what a difference. Also being a newb, I needed some advice on balancing the throttle bodies and adjusting the idle. A combination of TTP documents and Mikes quick email responses enabled me to make those adjustments perfectly. As you said, the power is there when you need it but in a very manageable way. The TORS are perfect for me. Nice sedate rumble when cruising but come alive when you open it up. This is now the perfect bike for me.

Hello, not contributing to the subject of the topic, but check out TTP's Safe Start. I had horrible dreams about broken idler gear boss when I first read about it on these forums. I'm beginner level mechanic but install was painless and gave me piece of mind

A bit off topic but I've had tennis elbow a couple of times, Nothing worked until Acupuncture, After 2 treatments each time it disappeared within a couple weeks

K.L, I have seen the TTP Safe-Start and it looks like a well-made part, but I don't see the need for our application. When researching it I ran across a number of Mike's posts on various forums over the years. They included the following bits:

"If you have the labyrinth breather system, you have the later strengthened engine cases. Nothing to worry about."

"...the later engines do it as well, but the strengthened idler gear tower/engine case can take it and stops the damage."

"It affects engine numbers up to 221608 & between 229407-230164."

Being a later model air-cooled bike with an engine serial number above 7621300 we should have the later strengthened case, I would think. We will not be be making any additional modifications--beyond the Stage 1 Torque Induction Kit and Tune 3--to increase power/compression/etc. I keep the bike on a battery tender whenever it goes back in the garage, so a low-battery starting situation is unlikely. It doesn't seem like it would be much of a risk given the particulars...

How dose the Twin Power tune effect the fuel millage on a bike with the OP's mods? Anyone?.. @PieMan ?

My 15 model Speedmaster went from 6.8 ltrs per 100km to 5.8 ltrs per 100km after I fitted 19 inch turnouts, K&N filter TTP Breathe & tune #3.

My last tankful netted 5.3 ltrs per 100km after a long trip.
