the whole build turned out great  Similar to the look I am going for.

[RustyRD]

Thank you so much. I really enjoyed this project. The bike was so complete that I quickly decided that it was going to be real close to stock at least in appearance. I still have the 400 engine in the frame that has the hot John Ritter port work and SpecII pipes.

What a brilliant concept of a bike. Maybe I don't get out much, but an orange '75 RD350 with a 400 in it has to be one of the best build ideas I've seen.

I had one years ago, 75 w a 400 motor. it was fun.

Beauty!

[RustyRD]

Thanks guys, that was sorta my goal. I had a bare frame and was building a roller when I stumbled onto this 75. I really look forward to getting the jetting close and seeing how strong the Ritter porting will be. I bought some brass for the carbs, I just need to free up some time to install them and establish a safe configuration. It is really rich at the moment, however it pulls good right off idle. Only 4-5 miles on the rebuild, so feeling it all out.

Today I took the time to disassemble the original engine from the RD I bought about a year ago, this is a number matching engine to the bike. I have not seen that before on any of my rd projects. Seems only fitting to rebuild it and place it back in the bike. Thought I would post some pics of the internal condition. An additional note, if you're not using JIS screwdrivers you need to make the investment. I have just in the past year purchased a set. Night and day difference in the fit. I guess I'm just stubborn but now I see the light.

Thanks for the input, I scored the new project for $300.00 . reminded me of deals back in the day. LOL

Excellent RD350B project bike ! 
I had 2) 350B's back in the day.

there you go. fwiw my r5 had the original matching cases as well but a 6 speed transmission out of an rd sort of wound yup in there 😅

[RustyRD]

Makes it more fun

I have ordered multiple times from Yambits, and I am so impressed with their processing and shipping of the orders. The genie is out of the bottle , I decided to polish the sliders I have about an hour invested in this slider.

Russ, those lowers/sliders came out looking real nice 

[RDryan]

I just recently polished the fork lowers on my RD and boy what a difference. That same old yellowed crusty look of the original...I'm guess clearcoated finish. All gone! Now they just look smooth and shiny very akin to the polished cylinder heads and polishing on the clutch and Sprocket covers. Not perfect by any means and a lot of elbow grease. I had never done it before and watched a lot of videos but I had some of the stuff necessary but maybe not the best of abrasives. I used what I had...3m 220 grit wet/dry sandpaper wetted with water. Then I made a huge jump to 1000 grit wetted with water. Then I used an old tee shirt and Mother's chrome polish. I did it till I got sick of doing it and it came out pretty nice but again not perfect.

[m in sc]

yup that works well. I usually last stage it with red scotchbite,  then polish. if ypu want to keep it clean and shiny, wipe down w lacquer thinner and thrn hit it with gloss wheel clear ( if you do it again)

[RDryan]

Good to know. Yeah I kinda felt bad doing it as I figured once you go that route there's no going back but it was just so far gone and it just doesn't seem realistic for me to try and recreate the original finish.
