Hello everyone, I was the lucky person who sent the float bowl, so in return I got a full set of seals, so as im in the process of making my bike as perfect as I can, I replaced all the internal seals and I will be using the others after mine have been sonicated, so I put the seals in, didn't change any settings, put them on the bike, turned it on, and the bike rode like crap, turns out my seals were all worn and leaking so all my adjustments were covering up faults, so these seals are very good quality, I would recommend to anyone, especially for the price. And Blair, as I joined this forum just to review this kit for you, you know you want to send me the carb mount o rings

Ho, ho, ho!
I sent you a pm.
