chance to buy rd350/400

    SpeedyE Experimental prototype, never meant for production

    Buddy has a basket case for $800.
    RD350 chassis + 350 motor + 400 motor + 1970's California made NOS racing bodywork.

    Is it worth driving over and taking a look at it? He about 10 minutes from me.
    Anything I should be looking at, or aware of?
    Or is $800 not a good deal, and so why bother?
    Thank you.

    Complete? If so, and it's in "ready to assemble" condition, then that's not a bad price. But (and it's big), the crank is the concern if it's been exposed to the weather. Also piston/bore size as you only can go so bike, and lots of racers maxed out the bore, then parked them as the four strokes/modern bikes got more popular.

    Take pics, post up here. Then we‘ll see

    Doesn‘t sound bad but there‘s also a bucket of „if‘s“ that comes with it

    RD's are seriously fun. If the engines are good,i'd snag them in a heartbeat if I was looking for a project.

    img_2719_22756933527_o.jpg RDs are serious fun. I had a RD400 for years. It was also a basket case when I got it. Needed crank rebuild, (new seals, bearings & rods), rebore & new pistons. That lot cost me more than the price I paid for the bike. I sold the bike on eventually and of course never made back what I put in it. It was still totally worth it for the fun factor:)

    350 cranks are available aftermarket, as are most of the other engine parts. 400 cranks are NLA, no one makes an aftermarket one, bu they are rebuild-able using modern parts. RD400 engines fetch decent money if you wanted to recoup some of your investment. Either way, $800 sounds fair.

    I was a member on 2strokeworld.com for many years (not sure what has happened but it seems the website is NLA). The guys & gals on there were a wealth of information about RDs particularly. Two names of RD motor rebuilders who spring to mind are Lyn Garland and Chuck Quenzler. If you can track either of them down they will do a top job on crank re-build and/or reboring.

    I thought I read somewhere the cranks were the same between the 350's and 400's.......just the bore made the CC difference.........no??

    So did you get it? RD's are the shit and RZ's just amp that fun up about 6 more notches. Ed Toomey is the man. I sent my RZ head to him for some cleanup and he did it the same day it arrived at his shop and shipped it out the next day. The most amazing service I've ever received.

    Before...
