VM29's are the expensive ones. The 33's go for less than half. Big knock against them is getting them to idle smoothly. It seems that's not what Mikuni focused on when designing them. For $150 they are worth a try for sure. Expect to fiddle with them a LOT before getting the jetting where you want it.

You are right some bikes can be bought cheap but usually, they are basket cases and the nicer carbs are already gone.
Don't know about that. My KZ750 cost $300. Guess it depends on where you live. The older bikes are cheap or free on CL around here. You can buy modern "nice" bikes for under 2K. But back to the question - what bike would the carbs you are looking from have come off of?
The 2.0 slides were too lean. I had a flat spot just off idle I couldn't get rid of. Had to run larger pilots to compensate. Mileage was crap and Davio found some 1.5's and sent them to me as a surprise. Cost him $100 but wasn't looking for payment. I sent him 4 $25 payments but it took a while to do it. Made all the differance. Went from #70 pilots down to 17.5, back to 1.0 air jets and 127.5 mains along with correcting all the holes drilled by the PO. I'm getting 40+ MPG on the FWY and the bike runs great. Still a little rich in the midrange and will get 125's today to wean it out a little bit more. It has to idle a little higher and I can live with that. I'll post the results in my thread.
At $150, BUY THEM if you can and if you don't like them, sell them here.
