I haven't had the chance to run it much, but I currently have an OKO 30mm installed on a blaster. Ordered a set of main jets for it, and have been please with the performance so far. Scored it cheap on eBay, just to have a carb for the time being. This blaster has FMF header, some kind of carbon reeds, OKO 30mm carb, and a pod filter. Plenty of go for the surveying I make it do....
Cheap good carb.....OKO 30mm.
