But the main problem is that it is very difficult to rejet the original carb properly. There are several air jets in addition to the multiple fuel jets. So many variables make it a trial and error nightmare. And you still have the potential problem of the diaphragm cracking or ripping.
The carb most often used for the conversion is a very simple, mechanical slide carb with two jets and a needle. There are so few variables, you can jet it without a whole lot of equipment or time.
On the KZtwins forum, there is someone selling single-carb intake manifolds that look really nice and are very affordable. The people on that forum will have a lot more detail on what carb to use.

For some reason im having a hard time finding them. Lots of forums about people making them out of brass though. Might go to a local fab shop and see how pricey it would be for them to make me one. Probably more than an 11th hour manifold, but who knows. As soon as they are back in stock i will probably order one, unless i find somewhere cheaper than $150. Planning on starting the hardtail within the next few weeks, might do a build thread.
