Carmen's Find

Carmen wrote in to let us know about his new toy:

Hey there! Im a first time R5 owner as of this year. I bought it from a buddy whose dad got it from a guy in PA that just had a few of them in a barn for 25 years. Your website has been super helpful. The bike has no problems running and is in the cleanest shape. Thanks a lot for making the website!

Rajdoot 350

Ajith wrote in to let me know about the existence of the Rajdoot 350, which was a licensed copy of the Yamaha RD350B, modified to suit Indian conditions. Even though production of two-stroke Yamahas ended in Japan in the mid 1970s due to emissions, these licensed copies were produced from 1983 - 1989.

Although the bike is basically a RD350B with a detuned engine and carburettors rejetted for fuel economy rather than performance, the front disc brake was replaced with a drum brake and the instruments were from the R5, making this strange cousin very similar to the bike which is the focus of this blog. The only Yamaha branding was on the sides of the engine - tank read "RAJDOOT". See below for an ad for the bike:

Mandarin Orange Paint Code

Paul writes in with a frequently asked question:

Hi. I am restoring an R5 and came across your thread. You mentioned House of Kolor paint but in regards to mandarin orange I didn't read what orange from House of Kolor you used? Can you let me in on this color?

Good question! I've gotten a bunch of email from others looking for the orange metallic paint that's used on the R5... see these documents:

1971 R5B (656k PDF) - Mandarin Orange over white
1972 R5C (756k PDF) - Mandarin Orange over black

Well, after rooting around a little on the internet, I found a discussion about this very topic:

There are no codes! House of Kolor has paint that will get you there. Here is a link: http://www.hokpaint.com

I have restored many early Yamahas and the orange you need is a candy shot over a silver base (fine grain). Black is black as long as all the black body parts are the same black. I've gotten a dead-on match to this color on my '71 R5 and I've matched the candy red on my '65 YDS3 and the candy blue on my '66 YM1 using these paints. The color varies depending on how soft or heavy you spray it on. That's how candies work, all the metalics are in the base coat and the color coat is translucent so more = darker. I hope this helps. Ed

So there you have it... there is no easy one-step solution. And, I'm not sure which HoK orange best matches the Yamaha mandarin orange.

However, I have found an outfit that is offering paint kits for all hard-to-find vintage Japanese bike colors, called Marbles Motors:

I am offering paint kits for the early 70's Hondas, Kawasakis, Yamahas and Suzukis. Perfect matches for the non-existent Candy and Metallic Colors that make or break a restoration effort. These colors have been elusive as Candy paints are not that popular these days, but I've managed to get the most popular colors matched and I am offering them in a kit along with the proper base color and catalyst that creates the original look of the bikes. E-mail me for more information. The paint is Deltron PPG DBC. If you don't see your color listed below and have a good representative part, I can do the matching process and provide you with the paint. Please be aware that the only shipping option for paint is via FedEx ground. Unfortunately, that means no International shipping. You get all the necessary materials to use or give to your painter with the exception of the primer and reducer. I can also supply the black or white paint for stripes, as well as the reducer if requested.

Looks like he has a Mandarin Orange paint kit that matches a 1972 Yamaha JT-2 mini-enduro (see examples of his restorations here, here and here). Same year as the R5C, so it makes sense that the color would match up - looks like it could, looking at the photos from his restorations. Worth investigating!

Get in touch with Randy Marble via email here.

Hope that helps!

"It's Better In The Wind" Trailer

It's Better In The Wind Trailer from Scott Toepfer. This video got me looking forward to getting the R5 back out on the road this season.

Giving up on R5 project

From Anthony, a reader of the blog:

The parts for sale are from a '72 Yamaha r5 350cc 2 stroke street bike. These were the precursor to the rd's. The main difference is that the r5's are 5 speed where the rd's are 6 speed and the r5's use piston port motors while the rd's use reed motors.

For sale is the frame, swingarm, center stand, footpegs and mounts as a package. I purchased this frame off of the previous owner with a lost title. He can furnish a bill of sale to myself. And I can furnish a bill of sale for the new buyer. Since this frame is older than '82 a paper trail is not needed when applying for a new title, but the bill of sale is always good to have. The vin stamping on the stem is clear and has never been tampered with. The frame is in excellent shape. Practically rust free. I am accepting all offers on the frame. Give me your best offer.

Also for sale is the engine. As stated earlier it is a 350cc, piston port, 5 speed, 2 stroke. The engine has been internally freshened up....new rings etc. There is approx. 2 hours runtime since the freshen up. The engine will come with all accessories shown including:

- 2 right side covers, shifter lever, 1 partial side cover, airbox, wiring harness, both complete carbs, and charging system rectifier

Once again, I am accepting offers on the engine. Give me your best offer and we can make a deal.

See the Craigslist listing for more details.

Recreating Dad's Bike

Kynan recently wrote in and was asking about the R5 for an interesting project he had in mind for a project bike:

My father had a R5 in 1972. He has spoke of it as one of the motorcycles he misses the most. I believe it was one of his first bikes. I found two pictures of him and the bike in one of my grandmothers photo albums. If I send you the images perhaps you can tell me what year, color, and any info on bike? I am wanting to build him an exact replica as a surprise. If I know some details I can find a bike to buy and restore. It will be a fun project. I have restored many bikes myself. I just don’t know a ton about the R5. Thank you for your time, I really enjoyed your blog!

After looking at the photos (above) and referring to this information:

1970 R5(A) - Metallic Purple/white
1971 R5B - Mandarin Orange/white
1972 R5C - Mandarin Orange/black

... we can pretty much determine that IF the R5 was stock, at least in terms of body panels and paint, then it must have been a 1971... Coincides with the "1971" that's penned in under the photos. (Here's an earlier post from this blog about determining the year of a bike, as well as a complete spec list.)

Anyways, this is turning out to be a very interesting story. I've asked Kynan to keep us posted about the build and to send photos when he can. More to come!

Campaigning an R5 "Back in the Day"

After coming across the BikeEXIF article, I received the following letter and excellent collection of photos from Bob Crossman:

Lawrence ...

Came across your site via a link from Bike EXIF. Neat stuff ...

I campaigned an R5 "back in the day" in California in the ACA, AFM, & AMA. Won the 72 & 73 AFM 350 Production Championships on my "ole R5". In 1973 I added the 6 speed gearbox and the front disc brake from the RDs. Here's some shots you might enjoy:


My 1st Race, OCIR... Rode to the race, finished 5th out of 39 starters.



3 Different ideas about the "correct line". (Turn 6 at Riverside)
From left to right:
Me in the Blue & White leathers, R5
Scott Clough in the middle (RD350)
Rod Murufas on the right on his RD350
Finish order that day was Clough 2nd, Murufas 3rd.



Riverside in '73 after adding the RD front disc brake.



Not an R5, but the Jim & Jim's/ND Spark Plugs RD400 that I campaigned in the 400 box stock class. 16 wins, no defeats.

Thanks so much for sending these in!
