Manual Madness!

Tom writes in with some great stuff he'd like to share:

I have been using your site for months now as I work on restoring my 72 R5C. I was kindly sent these files though from a fellow two stroker I met though Craigslist. He insisted that since this info is so hard to find that I should share it in any way possible. So I am sending it to you for if you want it on your site. I am not sure of the legality of this though. This info is very old and I doubt any publisher will say anything, but you never know. These files are quite large though and will take a while for people on dial-up. They have all been worth their weight in gold to get my R5C on the way to running again. Maybe in return if anyone knows of a killer deal on a pair of carbs for my bike they can drop me a line?

Here are links to the files. They're rather large, so be prepared for long download times:

And please, let me know if you can help Tom out with a set of carbs!

R5C 350 Riders Manual

Seeing as it's extremely hard to come by these days, and seeing as how mine is slowly crumbling, I figured I'd scan and post the "Rider's Manual" that came with the R5 when it was new. Fair warning though, it's a fairly large file. Enjoy!

Martin's Gorgeous R5 on EBAY!

Martin wrote in this morning to inform me that his YR5 (featured previously on this site here an here) is currently up for auction on Ebay UK.

Here is his auction description:

Yamaha YR5 350cc 2-stroke twin also sometimes designated the R5

This is an original UK bike, it has some history to suggest that it was raced in the early 70s and then converted to road use. It has only had 3 owners. The 2nd owner died in 1980 after which his widow stored the bike until it was sold to a family friend in 1999, since then it has stood almost unused for 7 years until I bought it last year.

I recommisioned the bike from the ground up

New battery

Full service,

Mot,

Hagon rear Shocks

New screen & Nosecone,

Reground Fork Stanchions and seals

The frame has been powder coated

and many parts chromed.

It has been a great bike to ride and has always drawn crowds at places like Matlock Bath. But unfortunately I suffered a seized the engine when the right hand 2 stroke oil pipe came loose.

After searching all year I have managed to find some original NOS pistons, rings& gaskets from America and Japan and have had it rebored by PJ engineering (motorcycle engineering specialists of Wolverhampton).

So far it has been rebuilt and started, that’s it. It sounds ok and has not currently done any miles.

I realised this bike is too rare to use regularly. So I have bought myself an Aprilia 250 because I enjoyed the two stoke so much

This bike deserves a collector, or Yamaha Dealer as a show piece, it would be great to parade or show.

The bike is in a Phil Read replica colour scheme, It has original Mead speed sports fairing, race tank & seat. The wheels have been upgraded at some point to RD400 alloys.

The exhausts are 1970’s originals and are stamped into the metal “Codnor Light Fabrications” this is a Derbyshire company that we now know as Micron.

It is fitted with Piranha Electronic ignition and starts first or second kick every time.

Front brake is disc with braded hoses using a standard RD350 front calliper & disc, so parts are no problem

I have some correspondence that the last owner past on to me from Padgett’s of Batley, plus Classic Bike, Yamaha, and Len Manchester motorcycles. This seems to support the case that the bike was prepped for racing, as many where from new and then put on the road by the 2nd owner. This seems correct as the fairing tank seat exhausts etc are all period early 1970,s but the rear light is from an RD400 which was not made until 5 years into the 70,s

Also included are the original Yamaha workshop manual and several magazine articles from magazines of the time in the early seventies

This is probably the only surviving example of a Yamaha proddy racer put on the road in the uk. Grab a real pierce of nostalgia.

I am selling as I have 5 bikes and my daughter is about to turn 16. I need the space for her 1st bike!!!!

The bike is MOT,ed and Taxed to October. The tax is free as it is tax exempt! The bike is in immaculate condition and is ready to show

Please ring for extra photos and spec.

Clicking on one of the words brings you to a single page with all of those posts. Useful if you want to see all the technical posts, posts with downloads, or say all posts about my R5 all at once, without searching or using the archive.

Colin's R5

Colin writes in to tell us about his recently acquired R5:

I have been looking for a nice two stroke for some time now. Something that was relatively cheap, but ran. I wasn’t looking for show quality or anything just something to get around DC on and tinker with. I came across this ’71 R5 owned by an older gentleman for over 30 years. Cosmetically it has seen some wear but the engine runs great and sounds great too. I sent along some pictures. This is exactly how I bought the bike. How about that sissy bar, amazing. Fortunately in about ten minutes the sissy and highway bar come right off. Short term I am going to put some clubman bars and some rearsets. Then slowly when the money comes in will start cleaning up the parts. It was a wedding present for myself. Great website about the only place I found good useful information on the bike.

Excellent find!

Sounds like you're on the same course as I am, with clubmans and rearsets. Funny, my bike came equipped with almost the exact same sissy bar! Weird scroll thing going on...
