ok here we go!! i started with just the boyson reeds on the stock cage on my 1989 cr250r was not impressed at all the reeds just seem weak? i could see light all the way around the cage. so i said enough is enough. so i bought the vforce reeds and cage. it runs awesome now! better then it ever has and i rejetted it to a 170 main and 50 pilot and this thing screams now i am about 280 pounds and this thing stands straight up in 3rd gear really awesome!! i recommend these to everyone!
