Can't wipe the smile off my face.

Another satisfied customer here. I took advantage of the need for a major service on my 2016 ST, including valve adjustments, to install the TEC camshaft. A local independent workshop did the installation and service, as well as dyno runs and ECU remap. The bike already had a decat and after-market exhaust. The bike feels stronger through the midrange and has a lot more top end than before. It also runs much smoother with fewer 'pops'. I've always enjoyed riding the bike but now it's even more of a pleasure. As the title says, I can hardly wipe the smile from my face.

Street Twin 900 Cam Upgrade

I have a 2016 Triumph Street Twin 900...this is a great bike, but its a bit tame in stock trim so I want to liven it up with a camshaft upgrade.

Emailed Tec to see if the cam was in stock, it was, so ordered the cam online and it arrived a couple of days later as promised.

I've not fitted the cam yet, going to start this today [23-01-23] Im very pleased with the service from Tec and the quality of the cam is manufactured to a very high standard.

Once the cam is fitted and run in, I do intend to have the bike on a Dyno and have the ECU Re-mapped [The Triumph Dealership in Exeter where I bought the bike have been very very unhelpful regard this subject]

Im not sure if Re-mapping the ECU is actually necessary, but the cam upgrade is significant change to the motor and I personally think this is a wise thing to do.

I will update my review once the bike has been on the Dyno

TEC "de restrict" cam in Street Cup

Was running out of ideas what more to do to my Street Cup so ordered the TEC cam. The installation took about 6 hours, had to change 4 shims to get correct lash. Weather in Sweden not permitting longer rides but on a short test run clear positive effect even though still running in on lover revs. Idle also i bit more "lumpy" in a positive way.
