Damn you pete!
UPS is supposed to be delivering my set today! I thought I'd be the first to review them and figured since I have stock BS34s, VM34s, and now these, I could do a little write up describing them all. Oh well, glad to hear they are going to preform as advertised. I also bought a sweet ultrasonic cleaner that I'm waiting for in the mail. I'll use that to clean the all the carbs for a good baseline.. I guess I'm not in so much of a hurry to do a review now, but I'll still try to get it done soon.
Highspeedhamish, From my understanding, these aren't just any PWK carbs. They were modified, designed, and manufactured just for the XS650 so they are specific to the application. Very specific.
