    Waste of money

    After hearing so many people rave about this kit I finally gave it a try, what a let down. I tried both the red and blue needles and jetted as per the instructions and I found the bikes performance was quite poor compared to the stock needle. I also expected more in the way of charts for jetting. All you really get is the two needles and a few dollars worth of jets. This is way overpriced for what you get. I will be returning or selling this kit.

    Bought for my boys bike. Came with everything to clean out his carb after sitting when I bought the bike. All the seal fit perfect and would buy again.
