last year of a well built, non smog Harley
#22
Yep, but that's not the problem.
'02 was the last year of the Timken Lefty bearing which supported the hot forged crank so well. It's only available now through the S/E P&A book at rebuild time.
'03 they went to a cold forged crank ( still decent,) then '07 that weak cast crank ( not so much!)
Biggest problem was the 07 cast cranks that slipped too frequently.
Personally wouldn't own anything newer than '02. ( Currently workin' on my second 100,000 miles on my '00 S/E RG.)

I don't know about well built, but here are the dates when the EPA implemented standards
Motorcycle emission standards were first established in 1978 by the EPA and have remained unchanged since the 1980 model year. Those standards are 5 grams per kilometer hydrocarbon and 12 grams per kilometer carbon monoxide (5 g/km HC and 12 g/km CO). Only one state, California, received permission from the EPA to set its own lower standard because of its unique smog problems and, in several stages, reduced its motorcycle emission standard to 1.0 g/km for 50-699cc and 1,4 g/km for 700cc and above motorcycles. The current California emissions standard is therefore 3 1/2 to 5 times cleaner than the Federal one.
This final rule follows EPA’s Notice of Proposed Rulemaking (NPRM)
published on August 14, 2002 (67 FR 53050) and supplemented by a
notice dated October 30, 2002 (67 FR 66097)
Emission Limits
The following table shows the new exhaust standards for highway
motorcycles, including scooters and mopeds.
Highway Motorcycle Exhaust Emission Standards
We expect these standards to be met through an increased use of technologies
already demonstrated as being effective on 4-stroke motorcycle
engines, such as secondary air injection, electronic fuel injection systems,
and catalytic converters. The standards are not expected to result
in the universal use of catalytic converters.
Class, Engine Size(cc)------ Implementation Date HC (g/km) HC+NOx(g/km) CO (g/km)
Class I----less than 170---------2006---------------1.0-----------_-------------12.0
Class II------170-279-----------2006---------------1.0-----------_-------------12.0
Class III---280 and above-------2006----------------_------------1.4------------12.0
--------------------------------2010----------------_------------0.8------------12.0
"I always say 03-04, he says 07-08", Looks like no winner in this argument

Don't know for sure but it would likely be sometime in the mid 70's. Carbed bikes had emissions standards long before EFI and catalytic converters came along.
Remember those EPA mandated non-adjustable idle/air screws and slide needles? And those choked up air cleaners and mufflers? They fostered the beginning of the HD aftermarket explosion.
I won't even touch the 'well built' part - too many opinions on just what constitutes 'well built'.
