I'm looking to buy new reeds for a 02 yz125. looking at the v force reeds need some input on which ones are the best and that would give me more HP.

You might of wanted to make the subject "reed block", but any ways. Some people swear by the v-force reed block. You can adjust them for more low end or top end. With the boysene (sp?) rad valve there isnt an adjustment. If i were you id go with the v-force rad valve. Just keep in mind, if you have the v-force on the low tension setting you have to replace the reeds more often. Probably at LEAST once a year.

Yep... the V-force is an awesome cage on the YZ 125's. It really makes a noticable difference. I have my reeds set to low tension - and there is a noticable gain in throttle response and the low-mid range power. I didn't really notice any type of effect on the top end power.

Shift-MX is right... if you set the reeds to the low-tension setting, you'll have to keep a much closer eye on them. Moto Tassinari warns you that if you choose this setting, the reed life will be significantly decreased (reason being is that the reeds open easier/more often). I have had maybe 30 hours on a set of reeds and found a chipped reed when I went to replace my reeds this past week. Many more intermediate-expert riders really like the high-tension setting and performance gains too, though.
