RT1 intake and carb....

I just finished my second restoration on a 1974 DT360 and got it sold on ebay. If you want to see it -

I am starting a refurbishment on a 1970 RT1 and just got it fired up for the first time today. I'm pretty sure it has a non-stock carb and intake on it. The mikuni carb has a 35.2mm slide with a big bell inlet that doesn't fit the stock air tube going to the airbox.

I went ahead and removed the carb and intake on it and found it does have a reed valve intake block. It also has an intake block with a spigot mount 1.57ID (40mm) I am fairly sure the stock VM32SH had to be a flange mount.

I have a book that says the RT1 and RT1B were both piston port injection and that the reed valve didn't show up until the RT2 in '72. So I must assume someone changed the intake block to a spigot mount with the reed valve just like my '74 DT360s have.

Any advice on if I should leave the reed valve in place it or put back to original - or does that depend on the piston that's installed?

Confused in Florida.

It's your call on the reed assembly.If you are doing a proper restoration change it back to piston port.

But make sure you do connect the carburator to an air filter some how.

Do you know if the pistons are different for the different types of induction? Can I leave the reeds in no matter which intake i use ( spigot or flange)?

From what I've seen, I think I want to go back to the stock set-up unless I can find a carb that will fit the current intake joint and air box connector.
