For the few parts that came in the kit it sure made a big improvement on the performance of my bike and no more carb overloading. And the kits arrived on the day they said they would. I had adjusted the floats so many times never getting them right. The parts fit so well I did one adjustment to the floats and have been riding the bike with no problems. Fully satisfied.
I always buy japan parts for motorcycles that are made in japan. K&L parts are the best, I build carbs and these parts fit very well and work the best of all. Buy good replacement parts and you get a good job done! Buy cheap and get cheap results!
