This bike never ran so good!
Install was super easy and the TTR fired up so quickly it kinda surprised me. Starts up every time even when hot and runs like a scalded dog. My kids love riding it now.

Fixed my bike!
I have a ttr 225 and it hated to start when it was cold. I have an fmf slip on and a custom air box, with this jetting not only did the bike wake up, but it starts much easier!

Does exactly what it was intended to do
This bike has always had a hard time staying running when cold, this jet kit works perfectly, with no side effects. It even adds a little more low end punch. Well worth the money.

CRF110F Runs amazing now!
-m-2015 HONDA CRF110F-- My daughters CRF110F ran horrible with the OEM jetting. I compensated that by turning the air screw in from the OEM 1 5/8 to 1 turn out. This caused the bike to run okay ish, but far from ideal. Now with this risk kit I am on 1.5 turns out on the air screw, and the bikes runs great! No smoking, perfect throttle pick up.

Made my bike harder to re start after it was warmed up.
This kit made my 2014 ttr110 run worse than with the stock jetting. Elevation might play a factor here I live at 986 feet elevation. With the stock jetting it took my bike about 6 min to fully warm up and run good after that it ran perfect and restarted easily. With the tusk cold start jet kit my bike didn’t want to start without giving it gas. It did warm up quicker than with stock jetting but the trade off of hard starting after it was warmed up was not worth it. I put the stock jets back in.

Works well until bike is warm
The kit really makes the bike easy to start but once it is hot from riding, it becomes hard to start on the trail. It looks like the main jet makes the bike too rich once it is hot. So, I suspect the idle jet is just right and the main could be a step or two smaller.

I put a fmf on my crf125fb ( not spark aressted) it will bog out after riding for a while will this help??
A shopper on Apr 20, 2019
BEST ANSWER: More airflow should shift your bike leaner. That is unless you have made adjustments in carb. Engines tend to need less fuel as they heat up. On our 125fb, the cold start kit makes the bike really rich once it is hot to the point that it can be hard to start hot. I would put half choke in when hot and see if that helps with bogging. If it does then more gas from kit would help. If it doesn't I would look again.
Is this cold jet kit tested for sea level? Or at higher elevation? Does it matter as much with 4 strokes?
Mark Y on Apr 21, 2018
BEST ANSWER: Even if running at sea level, this will help your bike start and run better. They usually come jetted a little lean from the factory.
