Carbking may chime in here but I'll tell you what I've found out. The YFs are a good choice for duals on a 235. The thing you want to watch for is to get the right YF. I know they made a bunch of different kinds. (this is where carbking will help out) Also they have to be identical carbs to function properly. I'd say go for it, should work out well for you.

You might want to contact carbking directly for his input.

Good Luck
