John Bottomley and his 1972 Yamaha TR3 replica

John talks about his fascinating experience in the acquisition of parts to build his beautiful Yamaha.

The TR3 was a very competitive production racer. I've seen them race many times.

[@Don-lw4cb]

Beautiful looking bike.

The RD350 was introduced in 1973 and ran through 1975 before becoming the RD400 in 1976

[@georgehayduke6717]

Made this engine for many years

[@mckinneyhunts]

Where did you buy the tank and tail piece /seat? I'm doing the exact same replica build. Frame, engine parts, barrels, Akront alloy rims tc from eBay

I know lets play some crap music when he starts the engine.

[@mrd4032]

Fun fact: 350 barrels and pistons fit straint onto a 250 bottom end. (1977 was fun on L plates)

What are the differences between a YDS7 crankcase and a TZ, can a YDS7 bottom end support TZ parts
