Firko's new flat tracker

[firko]

'in the first pics it looked to have a section for an airbox running along froim the side tab, but its not seen in the second set of pics so im not sure what going on there.]

What you're seeing is the footpegs. The seller bolted them to the inside of the number plate mount to get them out of the way for shipping.
 

MAybe lotsa stockies were sold in 69, but i was referring to custom build frames, would only be a few makers doing the 2ees was my point on that.

When you said "only a couple of guy had access to them first motors" I presumed you were talking about motors. I agree that there weren't many frames in 69. Ray Hemsley and Harry Hindall for sure but Harry only made two or three flat track frames. The rest were motocrossers.

It doesnt have an engine shoe like a champion, with that rear mount more like the PDV fixed pointbut the front mount is very sonic weld style. im wondering if it was made up in a shop by one of the guys doing foreignee

It's pretty obvious now that it's neither a Champion or a PDV. You're possibly right but I'd like to know who that "shop guy" is? Who's "Dan the creator" who was proud enough of his work to sign it?

The swing arm plate is very agricultural and is the odd part like it was cut in on the job.  Whats the line on the arm, is it the chrome or is it steel and thats the drawing line ?

The plate's no more agricultural than the Champions I've owned or on the Champion swingarm I have here now. In fact, but for the very slightly different shape, they could have been made by the same man. I don't know what the line is, it's like a flaw in the chrome...I'll see if I can polish it out when I get to that part of the build.

Just thinking out loud

I'm glad for the input, it's a mystery that needs solving. Last week I bought an RT2MX engine from a guy who races a Champion RT1. He told me that he was originally interested in the bike but was put off, thinking it was a PDV. He now reckons he should have bought it, seeing more clearly in my photos that it's not a PDV. 

Below is a comparison between the Champion, PDV and my mystery frame. There are strong similarities between the three, minor details being the only way to separate them. Note similarities on this Champion swing arm rear axle plate to my new project. Almost the same. Although its unclear in the photo, the PDV is similar as well.

Are you sure it's not a Racemaster? Looks like the larger Racemaster s I have seen. never was one for a 2-smoke before ,but could be. they built some that looked like Champs and some that were off The Trackmaster/Triumph platform. Don't know who those  guys were. The welds look too good for early Jerry Cheney,but he built a lot of swingarms with a top pivot lug.    TCL

Now this is a sweet little flat tracker. It's got the unobtainium chrome bore DT1-MX barrel (he's wrong, it's not DT2MX), a hard to find C&J DT1 flat track frame, Barnes wheels, Airheart brake, a Maely tank and all sorts of cool stuff. It's not cheap by any standard but for anyone who's into early Yamaha framers, this is bordering on holy grail stuff.

mikuni,K&N, recent new clutch plates,T&M pipe, Maely fiberglass tank coated w/ Caswells, Dallas Baker /C&J nickled frame,
Yamaha forks and chromed triple clamp- pealing a bit, Kenny Roberts bars,Spool w/ Akront and Pirelli tire, Rear Barnes quick

Cool little dirt tracker firk
Theres some nice dirt trackers for sale in the states thats for sure
Is that bloke in the pic a mexican 

[firko]

I might be onto a bloke who's producing made to order Sonic rigid frames to suit a number of different applications. If all of the planets align I'm considering using one of my growing flock of DT1/RT1  engines to build one of these...............

This is Don from Metro Racing's genuine rigid Sonic framed DT1. Cool.

Meet Don while I was there, he is a big bloke, must be well over 6 ft. He was riding a real trick looking Bighorn with xtra finning, very neat. Not surprized with that DT1 pic, Springsteen rides some of his stuff.

I logged onto Marks Swapmeet this morning and was greeted on the opening page by this picture our Freaky on his Champion DT1 doing his best Gary Nixon impersonation .
 

By the way...where is Freaky hiding?

How nice is this Champion DT2 that's currently up for sale on www.vft.org.  I'm not in love with the colour coded barrel/head but other than that it's a well laid out bike.

1972 Yamaha Champion 250.    All the right stuff!!   Salida, CA.

I noticed that myself Firko.  Salida is about an hour from my house and the price is not too crazy.  If the color scheme was classic Yamaha yellow w/strobe striping I might not be able to contain myself.
 

I didn't like the way the rear of the seat fits the fender though.

[firko]

Jay I reckon that little Trackmaster DT2MX I posted a few back is a much sweeter bike. It's got all of the bells and whistles including an unobtainium Maely tank like I've been looking for for 20 years.
The closer you look at this bike, the better it is....to me anyway .

[Freakshow]

Been busy, raced long track last week.  awesome fun. just trying to sort out the 2 vavle ( needs a head gasket ) then park it ready for the winter season.  then onto building bikes to race this year.

Firko, purple bike #52 above is an 69 Trackmaster frame and later glass.  ( looking for a 5" rear guard and solo/pillion for that one. ) But way too many progects on the go to finish em all....

[firko]

 Here's a couple of sneak preview shots of my little Fasttrack Yamaha 360 that should be completed within the next couple of days. It's come along way since the little grey primer tanked bike arrived from the US a year or two ago. I had intended to take it to HBBB but illness with my travel partner saw us having to postpone at the last minute. I'm pretty happy with the way the bike's turned out  but it'll be undergoing further changes including a new reed valve race engine before the Nats. I'll finish off the few loose ends and detail it a bit and then take some decent photos over the coming weekend.

So some of these flattrackers do not have a front brake, can they run at nepean DT in the same class as the CR's and YZ' run in?
