Yamaha rd350 Road Racer Liquid Cooled!!
« on: Jun 22, 2016, 20:39:36 »
Well, I cut down my project pile in favor of an rd350, some chambers and a cool old school road race fairing. Got rid of my hs1 90 Yamaha and gt380 basket case.



Came home with this.






Plan is simple in theory. No creature comfort, road race style bike, barely legal. Ported r5 motor with the 6 speed rd350 transmission. More to come, hopefully since this is now my only bike project, I can keep this one going.

Now you're talking!

Looks like the shocks need an upgrade …

Awesome I've got a similar plan in mind for my next project!  I like the full fairings on the RD too

Sounds like a plan.  400 box is even better if you can find one at the right price, and of not 350 trans will work too.  Fit a decent ignition  (anything but points) and you should be good to go.

If you don't mind, I'll probably pick your brain a bit during this project. Word on the street is that you know a thing or two about 2strokes and road racing :)

You may have heard that from my publicist who is truly a great man and everyone loves him, and he has been incredibly successful.......   Too much election coverage for one day..

PM me any time.

For better driveability, use the RD cylinders over the piston-port R5.  The reed valves make for a much more enjoyable experience.  Teazer is correct on the 400 trans too.  Closer ratios in the top gears.  Are those Bassani pipes? 
I like cilp-ons, clubman's and superbike bars depending on the bike.  And rear-sets.

I think I'll stick with the Rd gear box for now, only because I have it available, and monies need to be spent elsewhere on the project lol I'm not opposed to the reed motor per say either, I think I'll start by tearing them both down and seeing what I have
