Product Reviews

Review: I hesitated for a long time before taking the step to improve my bike. By choosing the GMan package, I have no regrets. Easy to install, even for a novice. The technical service is very attentive to any questions or problems. Everything is ok and I recommend GMan!

Review: I've had my performance package on for about a week now and I knew GMan would do me right and he has! My girl, Leen, is a different type of animal now she's a beast! My only regret is I wasn't able to do it sooner but I'm not going to let that hold me back from enjoying it every time I ride!

Review: Super easy installation, literally plug and play. I had zero issues installing, and so far the performance gain is noticeable. Bike lugs out far less at low RPM and is much more responsive when rolling on the throttle. I paired this with a Cone Engineering quiter core muffler (2 into 1 setup) I have not made any alterations to the tuner yet, but plan on experimenting as I believe it is running just a tad rich right now. Overall, a huge improvement. Anyone running stock pipes and intakes should make the change to allow the bike to breathe! Totally worth it!

Review: Well worth the money! I ordered the performance upgrade and it was very easy to install the air intake. The EFI took some effort, but was easy enough to install once I knew what I was doing. Since I also have aftermarket exhaust, it was good to know the preset was already ready for Stage 3 upgrade. Now my bike is a completely new machine. Best investment I made for it. GMan is a great guy to talk to and help with questions. Thank you!

Review: You have to have this to get the best from your C90T. I just struggled a little in finding the right settings -I have stock pipes on- but when I did, well, that's a new bike. I was not looking for better performance, but for smoothnees. I got both.

Review: Holy smoke!!! These are the best words to describe this performance package. The power increase is AMAZING! Thank You GMan for allowing my bike to unleash it's true power :-)

Review: I am not a mechanic, but I do understand that there is a balance between an engine breathing, fuel management and exhaust. The factory pipes and intake on the C90 are very restricted. If you replace your pipes, this kit is a must. Holy hell man, it's like a new engine. I had no idea how much power this engine could deliver. Pair this kit with GMAN's 2-into-1 pipes for a complete performance overhaul.
