power jet carbs

[Deleted]

been trying to research mikuni power jet carbs (re the fastest 125 thread the micron bike). i can find about the carbs and about the conversion kits.
can you put the kit on an rd mikuni carb? (26mm dt125 34x)
what benefit does it have and where can i get a 32/34 mikuni power jet carb?( if needed).
thanks for any help Jamie

Aower jet carb is not a kit for a standard carb it is a carb that has a smaller main jet but is backed up by a second very small jet. A standard F2 ypvs has a 26mm powerjer carb, and is a good up grade for a 125lc with a tine and a expanshon pipe on if you go up to big on a 125 you will get a bike very fluffy at low revs and not nice to ride at all . a standard 125 is a 14mm carb. 28 would be the bigest you whant to go. Thats a RD400/ TZR250/KR1,KR1S carb.

er WRONG standard mk1 is 24mm (and mk2) mk3 is 26 mm.
put this thread out elsewhere and found out that; the power jet is mainly for top end, that is it only comes into play when enough air is rushing through the carb.
they can be fit to virtually any mikuni carb, i have found sites that supply kits for them.

Yes 14mm he he thats not even a 50cc ofcourse its 24mm on a 125. Id like to see the kits to fit to standard carbs i have only seen powerjets on F2 TZs TZR and the likes and its all inside and part of the carb.
