but got bit by a $2 part.
I am rebuilding Dave Hughe's TR3. It was once the worlds fastest air cooled two stroke (it was clocked at 154 mph dropping into the bowl at Daytona in the early '80s. Ed Erlenbach's RD400 did 161 mph on the salt flats last year. So I got the worlds fastest air cooled two stroke that can corner)
... so any ways...
I bought a TA250 motor off a guy in Hawaii, to convert to a TR3-350 motor, the bottom end is the same, the top end is different. The TA/TR motors came out in 1971, sort of a stop-gap measure before Yamaha introduced the TZ in 1972. Don Embe won the '72 Daytona on a TR3, starting off Yamaha's 25-30 dominance of GP racing.
The bike was only available for about 6 months, to a VERY select bunch of racers, 50 years ago. They're kinda hard to find.
...so any ways...
I received the motor from Hawaii on Wednesday afternoon, and immediately tore into it, to see what condition this 50 year old motor looks like.
I couldn't have asked for more. It's been a LONG time since I have seen a old motor in such great shape. It cleaned up really well. It doesn't look like it's been rebuilt a million times (it IS a 50 year old race motor). after I washed off the rime of what ever that brown stuff that covered every part of the outside of the motor was, even the covers looked great. This is definitely a VERY low mileage motor.
This makes me happy.
...so any ways...
Some may call it hoarding, I call it being prepared, but I THOUGHT I had all the stuff I needed...
It now has:
(remember this is for a 50 year old racer. This is stuff I had in stock)
All new OEM seals and gaskets
All new clutch and trans bearings
All new OEM clutch
Rebuilt crankshaft with new upgraded main, big and small end bearings
New OEM rings
The motor is sitting on my bench, all back together except the top end, because I don't have OEM piston circlips.

I have Wiseco and Mataka circlips, lots and lots of Wiseco and Mataka circlips, that don't fold in. They're just a circle.
They'll go in, they fit, they'll hold the wrist pin in place, but I'll NEVER get them back out again.
CARNSARN IT!!!!
I was on a roll!
On to other things I guess.
Always another bike to fix.
