    I say go for it! Why? 1. It is a first year RD350 and it looks to be entirely original, no big dollars finding things. 2. Go slow, get all the good help you can and before you fire it up take it to someone who'll double check it all. 3. A friend had never had a motorcycle, although he built bicycles, bought a couple boxes of late 60's Honda CL350 parts and built a perfect runner & looker. He did it, you can too.
    4. Its' an RD350! (full recuse/disclosure former RD owner/rider).

    I hang my head in shame. 1973 fiche shows you are correct on the slides. It was 1978 when I last did a top end on an RD350. http://www.starmotorcycles.com/part...50_(1973_MOTORCYCLE)/CARBURETOR_(RD350_-_1973)

    You got all this right, except the choke is on the left side on and RD. Oh, and carbs don't have bowels, they have bowls:D.

    hey jonny,,ya got to me,,,these days i have a hard time differntiating if the bowl or the bowels are moving,,either way,,stay out of the way:rofl

    regarding the ''choke'' don' think i ever would have used that word on any RD since they don't sport chokes[ a device that ''chokes '' off the air supply on the air filter side of the carb versus an ''enriching system' used on all RDs,,,it uses the throttle slide in the complete down position to actualize itself ie the slide is essentially what the guillotine choke is in a ''choke'' system


    so FYI when it's cold outside and you want o start your RD you essentially have to leave your hands off the throttle in order for the 'enriching ' sytem to work

    soon

    I know, I know. Choke is one syllable, enrichener is four. It even says choke on the lever.

    Don't change the colour scheme, PLEASE.

    If it is in original, un-restored condition, maybe you should consider doing nothing to the finish, just restore the mechanical side.

    I've still got my RD250. I regularly holed pistons and stuffed it up, when I was a know nothing 17-18 year old. When I first got it it was partially dis-assembled and I managed to put it all back together again.

    Clean it up so you can see the components that you are about to tackle. Sit and look at them before you start with the tools.Edit: should've said "Sit & Look at them, with a manual, before you start with the tools!!

    If in doubt, save the cash and give the parts to someone who knows what they are doing.

    Be patient and, in 10, 20, 30 years time, you'll have spent 10, 20, 30 years being proud of what you accomplished.

    The 350 was a true giant killer. It will put a smile on the face of anyone who rides it.

    I love riding mine. Makes me feel like a kid again. Apologies first but they look better in Butterfly Blue.

    One more thing. Maybe you could see if it is an RD350 or an RD350A. The A was released shortly after, not sure what alterations were made, if any.
    The only differences that I am fully aware of was on RD250 came out with a TLS front drum & 9 litre tank The RD250A had the single disc and a 13 litre fuel tank.
    In Oz, the RD250 (like mine) was first delivered to customers in late '72, as a '73 model.

    I would bet a beverage that the slides are stuck and getting them out on the bike is tough
