1972 YR5 Renovation Project



Paul Watts wrote in to let me know about Stephan Morris' just-started teardown and restoration of his R5 in the UK. The level of detail in this article is excellent, going step-by-step and photographing everything.

I for one am going to be paying very close attention to this restoration as it progresses, so that I might pick up a thing or two - for the rest of you I'm sure this information will be invaluable as well. Thanks for sharing, Paul!

Enjoy!

Attention Canadians!



PROJECT ALERT! I spied this 1970 Yamaha 350 R5 on Vancouver Craigslist. Don't ask how I wound up looking there. Anyways, the first $250 gets it!

Concept Renderings



Brian forwarded me this great portfolio of vehicle designer Heikki Naulapää. I've seen his work before in the very interesting Aprilia Magnet 3-wheeler. I also found this great Aprilia RAM concept concept pictured above.

Dig the reverse grips and levers, front swingarm, seamlessly blended multiple exhaust, and aggressive helmet-forward riding position. I'm gonna have to keep an eye on this guy...

More RD350 Videos

Chris has been posting a lot of videos of his RD (from a few posts back) up on YouTube. You know how the kids love the YouTube these days! I really got to get some video of my bucket of bolts up on there... Anyways, here is a great video walkaround of the bike:



And here it is making that sweet two-stroke music:



And, finally, the moment you have all been waiting for - the burnout:

Velorex?



My friend Russ just sent over an interesting vehicle offered up for sale on eBay - a 1968 Velorex 16/350. This crazy Czechoslovakian wonder is powered by (you guessed it) a two-stroke 350cc motorcycle engine. Check out those body panels... made of vinyl! And check out the crazy tubular chassis (and motorcycle gas tank) with the vinyl removed:

UK 2-Stroke Rally Footage



As per the poster:
The Aircooled RD Club's annual rally run out at Ashbourne UK July 2006. 125 plus bikes en masse on the road. Probably the biggest 2 stroke meet in the world.

Chris' RD350 Progress



Chris wrote to me back in October of 2005 showing me his newly acquired 1973 RD350 (see here for post and "before" pictures). Well, over a year has passed, and he's made quite a lot of progress on his machine. Let's see what he's done:

  • Newtronics ignition (I would recommend installing this, worth the money)
  • New Wiseco pistons (lucky that the stock bore just needed honing after finding that one of the lead counterweights let loose off of the crank and went whizzing through the rest of the motor)
  • Used crank from another R5 motor I purchased as scrap from local motorcycle shop (50 bucks! score)
  • Polished all the aluminum I could on the motor before re-installing
  • New stock seat cover (Ebay not cheap)
  • All new black paint job
  • New stock hand grips
  • Rebuilt carbs (found the piece you posted quite informative)
  • As the cold weather approaches, the next task to tackle is chrome spokes on some aluminum rims
I almost sold it on Ebay but, was able to feel out how much I could get for it. I couldn't bring myself to part with. Anyways, keep the website up. It seems that there is resurgence in popularity in these bikes.


I agree, there has been a resurgence in these bikes. They're cheap, simple, fun and good-looking. Good to see such interest in getting these guys back on the road, and in such good style as Chris' ride. Just take a look at this engine:
