Worked great on my sons Yamaha wr250. Only problem is I had to order a second roll. 1 roll is not even close to enough.

I run these whenever they are available for my carbureted bikes. You dont need much knowledge of jetting to get the bike running perfectly and the instructions are easy to follow. Plus the power increase especially in the low end on my two strokes is phenomenal.

I installed the mixture screw on my Ktm 530. It fits perfect and I can now easily adjust my mixture without having to have a special tool.

Normally with mods like this I don't see huge gains in performance. Rest assured, this kit is different. I recently installed this kit on my ATV and noticed an instant increase in performance. Kit came with QR codes for installation instructions. 10/10 Definitely recommend

I like that there is a cheaper alternative, and looking up sizes is easier than checking the microfiche for each bike. However, the numbers aren't stamped on them as clearly, and my results in jetting using them isn't as consistent as with genuine jets, so I suspect the sizing tolerances aren't quite as good, though I do not have an accurate way to measure them, it is simply my experience over several years over several bikes and ATVs.
