    Nice Kit

    Very easy to install kit. CSC has good step by step instructions. I’m at 4200’ and the main (112) ended up a little too much. The #40 idle jet has helped on the lower end though. Bike is completely stock as a reference point for anyone else tuning at any elevation.

    Works great! CSC makes it extremely easy to install with their video. My TT 250 is running great with the upgraded jets

    Smoother throttle

    Posted by Dave on Mar 23rd 2022

    I put about 200mi on my TT250 before swapping the main jet with the #112 (my area is around 700ft elevation). The difference is astounding; Smoother idling, the throttle isn't nearly as twitchy as it felt before, and it sings nicely at sustained speed. Basically everything just seems to run much smoother than it did. Definitely recommended! It took my literally one hour to swap out.

    Jet Kit for TT-250

    Posted by Tom Wilson on Feb 28th 2022

    We just installed this jet kit in my son's TT-250 and wow it made a difference. Seems to start quicker and definitely has more power mid to high range. We used the 15 main jet and gave it a little more fuel by moving the clip down one notch on the throttle pin. thus raising the pin up one notch. I am probably not using the right word (Pin)---LOL! We would recommend it--I am going to order a kit for my new TT-250.

    Definitely worth it, but needs instructions. Video doesn't cut it

    For Reference( I'm at sea level in san diego). I'm not super good with carbs, so I just followed what the last guy did kinda. Except I used the 115 jet (go for gold am I right?), the third c- clip spot from the top on the needle(that's the thing that unscrews off the top of the carb when you're removing it from the bike), and I tightened the air mixture screw down all the way then backed it off 1 and 1/4 turns. I don't know if that was right, but it definitely fixed my high rpm stutter, and there is more power. It would be great to have actual instructions for this thing.

    Noticeable power gains

    Posted by Chris on Apr 10th 2021

    Great little kit. I only used the 112 jet instead of the 115 and raised my needle up one slot by loving the c-clip down. The bike feels like it has more grunt right off the back. The only reason I gave it 4 instead of 5 stars is because the replacement idle screw head broke off immediately as I tried to put it in. Appears the w hole had a little gray gunk in it from the previous screw I took out which gave some resistance. I just ended up using the original screw I cut my slot into and that worked fine. My next step will be regearing for better highway now that I have more power.
