yes, stock carbs. the 904 kit was roughly 1000.00 the air box kit was 250, clutch was 150 and labor for all was 450...i already had the pipes and the sprocket. but the pipes were 600...so rougly 2500 total i think the carbs are 1200 but they propbably would have changed me the same price for labor (really cheap)

glad to hear you are enjoying your 904.

IMHO you will have to go away from the stock carbs to really get that motor dialed in right. With the stock carbs it is hard to get enough fuel, fast enough. I messed with the CVKs and think I wrung everything I could out of them, and still couldn't get above 90rwhp. Switch to the bigger flat slides though, and oh boy, that motor will really come to life.
