from Berkshire.
You can get genuine part from Fowlers for £105.
P J Motorcycle Engineers in Wolverhampton rebuilt my CT3 crank with a pattern kit, rod kit (supplied by them) was £31.50 and crank rebuild was £45. Their work is very good.
Part number is 3R2-11651-01

Just a thought. I'm pretty sure the CT1 & AT1 piston port rod is different in length by about 5-6mm compared to reed valve CT2 & on CT3 etc models. Please correct me if wrong.

Same con rod on 69 to at least 1981 in the AT, CT, DT125, and DT175 models...  also MX, YZ, and IT 125/175 until at least 1979. 

Not hard to find at all.

At least the first decade of the 125/175 bikes were very consistent in dimensions...  it's the 250 and larger bikes during that era that have all the muddled up rod lengths and port heights.

Good old Yamaha. So many interchangeable parts over the years. I guess the trick is to know what works & what doesn't. 1980 YZ100--3R2 rod & probably other years too.
