I saw your TZ750 swingarm on eBay right away as well.  I'd love to 3D scan it for posterity, but I can't justify the purchase price for a project I'll probably never get to!

I believe Richard Dunkin in OK still has a TDR or two available.

Do you have contact information for Richard Dunkin?

Besides, it looks like something that you do need so you can run out and get groceries.

Yes, I will have to build a small rear rack to help justify the purchase.

Yeah, TDR is another one I'd love to own, but also super hard to find.

I knew I'd get positive emotional support here!

I am hunting for an R1-Z, and may have found one here in the PacNW.  I've never ridden one, or even seen one in person, but I think they're cool. 

Based on the early TZR250 engines, detuned slightly from what I understand?

Anybody spend any time around them, or know anybody who can tell me what to look for before I spend a bunch of money on another bike I certainly don't need? 

I had the same experience with All Balls seals once. Won't make that mistake again.

Wade is right, just ride it and you'll be fine.  But, you will use way more 2-stroke oil than you expect.  I wouldn't be surprised if it took over a tank to get to Leavenworth and back.

Hit me up if you head to Leavenworth on a weekend, I'll try to meet you there for a burger or beer.  I'm only 20 miles away.

Chris, I have a stock 79 Daytona Special one-piece head that I'd like to "modernize".  I haven't researched enough to know what that entails besides updated squish bands.  If you have any interest in the machine work please let me know.  Thanks!

I was hoping to be back on the road by my birthday in April, but didn't quite make it.  However, I did make it in time for Dad's 80th birthday last week.  He jumped right on and away we went, with me trying to keep up on his 125 Honda.

I ordered some oil pump check valves, since one of them seems to be leaking, and I think I'll go down one size on the main jet.  But it's pretty close to done. (for now) 

Thank you to everyone here that offered parts and answered questions.  Go for a ride!

Yes, I understand why people cut them in half, but I'm not interested in cutting apart this head.  I'll find a big enough lathe eventually, or someone who wants to run it in a CNC mill.

Niche Cycle on eBay has the 175 series P2 needle jets.  And they're located in Florida.

Look over the jet needles closely as well, if they're high mileage, the anodizing wears away and fueling profile changes drastically.  Niche has stock 5L1 jet needles too.

Thank you for the details about head gaskets.  I'll measure the one piece head gasket I have here and see how it compares.

I am interested in having the 2V0 head machined to modern specs, but I haven't found anyone with a lathe big enough to swing it in once piece. 

Thank you!  All the DG stuff is going to the previous owner for his 77 RD.

I have heard the DG heads are terrible, and that the Daytona head was also terrible.   

How drastic of a tuning change have you seen between the two?  A couple jet sizes?

Nothing special, but first start after 20 years of sitting!  And 45 years since I first heard stock exhaust!

Still have to bleed the brakes and oil pump lines, modify the chain guard to fit with the YSS shocks, sync the slides, and lots of other little things.  Hopefully on the road tuning this weekend.

Thank you for the compliments.  Dad looked at progress right after welding, and said, "Maybe you should have just gotten another frame?"  I can't argue, that would have been much easier.  It's been a challenging but fun project returning everything to 1979.
