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:

Entirely CNC-Machined Cycle

Another crazy O'Toole (no relation... ?) has just completed the RV100, a machine where all parts were designed on the computer, milled using a CNC machine, and where the only welds occur in the fuel tank:

The concept behind the bike is to eliminate the paradigm of the welded tubular frame. Welded tube frame are labor intensive, require expensive jigs and fixturing, and the quality of the weld is very much dependant on the quality of the welder. In contrast, the RV100 frame components are cut on a numerically controlled machine (CNC). This makes the production of parts very repeatable, and makes the production of unique parts routine.

Very, very interesting technique, and also pretty interesting to look at, even for a test mule.

Ebay find - Speedway Racer!

Spied this beaut up for auction on eBay. From the description:

Return of MV Agusta to racing in America

From MV Agusta USA:

The return of MV Agusta to racing in America is a reality. Using the F41000R in Superstock trim, Eraldo Ferracci brought the rudiments of his team and a pair of young riders to Jennings GP for a private two-day test using Pirelli tires on November 8 and 9, 2006.

Italian Superstock champion Luca Scassa (age 23) and American Matt Lynn (age 22) turned laps under mostly favorable conditions at the Florida track looking for basic setup information and a shakedown for the nearly stock motorcycles.


Scassa is well acquainted with the MV Agusta motorcycle and brought his suspension settings with him to an unfamiliar track. Lynn has raced at Jennings GP but started from scratch on a bike he had never seen or ridden. Both worked through the challenges diligently to arrive at a point where they could begin fine-tuning and offering feedback to keep the MV Agusta technicians heading in the direction of fielding a competitive machine for the US Superbike series.

By afternoon on the first day, both riders were already tantalizingly close to the track record of 1:15:444 of Canadian champion Pascal Picotte set earlier this spring at a joint test of all the Canadian Superbike teams. Just before lunch on day two, Scassa went 1:15.448 and Lynn 1:15.545 hand-timed.

Under sunny skies and with track temperatures climbing nicely, Scassa smashed the record in the mid-afternoon with a 1:14:81 and backed it up a lap later with a 1:14:85 on spec Pirelli tires identical to those used in the Canadian Superbike Championship. Lynn's best of 1:15.2 was also under the old track record and two seconds faster than he had ever been at Jennings GP.

Scassa said, "It's cool being in America, but for sure I came here to do a job and we did some good work. We have much more to do to make the MV Agusta into a superbike but the bike is good and work is OK for me. I'm excited to do this."

"I'm really excited," Lynn added. "We came here with a blank sheet of paper and went to work. It was a lot different from what I have been riding, but once we got the MV basically set up it was really fun. Eraldo knows what he's doing and what he wants. We just kept at it and that's what we need to do. I can't wait to ride it some more. It's fast!"

Ferracci will now travel to Italy to consult with the factory again, delivering information from the test and input from the riders and technicians. The next outing for the Fast by Ferracci MV Agusta F4 1000R will be at the Daytona tire test in December, after which the team will prepare in earnest for the 2007 AMA Superbike Championship.
