Yamaha R5C - TR3 Race Rep

That looks like similar to the one on the TZ250(A) above but with some differences in nose shape and side trimming.

The first street TZ/TR I saw had an RD400 motor in a TZ twin shock frame but no fairing and in some ways it looked more aggressive than one with a fairing. It was so simple. My first RD was also an RD400 stuck into a TD3 frame with a horrible set of mismatched parts on it.

I have also repaired and rebuilt a couple of RD based TD3 racers with a mix of original and replica parts. One used a fairing similar to that one but in two pieces - nose cone and belly/sides. That bike was mostly TZ250 twin shock with a TD3 top end and RD front end.

That one had TZ/RD wheels and a GT750 rear brake cable to go with the Vesco longer oval tube swingarm that I swapped for his OEM rectangular swingarm.

That frame looks similar to the YZ frames with the monoshock through the spine. Is that a factory frame or custom deal?

It's a TZ250E (1978) frame. Similar to the TZ C (1976) and D (1977) models but with replaceable alloy engine plates that used to crack and are almost impossible to find now.

Ill get back to it. I know it wasn't meant to, but this project has the ardee wheels turning in my head again ;)

At the risk of thread jacking Sonreir's thread, where is that RD project of yours at and what are you thinking about doing with it now? Maybe a high dollar long stroke, long rod banshee motor, or perhaps a long rod 350 or a simple TZ750 top end transplant? maybe something more budget friendly like a mildly tuned RD350.

Its safe and sound in the corner of the garage. Plan is the same, the rd350 liquid cooled up end that has all the port work with those chambers that I got off of von yinzer a while back. I got distracted by the likes of BMW and Suzuki dual sport shenanigans.

Though, a friend in Canada has a few non ported lc barrels that he can get me for a fair price. It may be nice to start fresh with stock porting that will not yield such a narrow power band for a slight bit more streetability...
 
Thread jacks totally permitted. Gonna be a while before I start making progress on this one and inspiration is always welcome.
 
That reminds me, Joe Spooner over on two stroke world created an amazing TZ replica out of an RD and he grafted a ported TZ750 top end on it. I don't think he fitted a fairing (yet?) and his has lots of custom machined parts.

I know this isn’t a yamaha, or even a 2 stroke.
But it’s what i would go with for lighting

Interesting idea, but I'm afraid this is all I'm seeing right now. :eek: ;D

That's a bit more my speed. I was also thinking that the over/under combo seems to be in fashion. If I can still get a single round headlight in there, I'm also considering that option.
 
Let's change this from Race Rep to Race Prep. Get this thing sorted and safety wired and come play. AHRMA and WERA have classes this will fit into nicely and they are competitive bikes with the right rider.
 
H section shouldered rims of course! I've bought them pretty cheap from Mike's XS, but on occasion had to re-angle the spoke holes and massage the bead seat where the ends of the extrusion are welded together - not a big deal. I've used their stainless spokes as well - very nice, and also very well priced.
 
I got her home from my friend's place. Looks like I have some work to do.

Also, anyone make their own top triple before and care to do it again? ;D
