where the warranty work issue vs modifications comes into play is NOT with magnusson - moss, its with epa.
the epa tampering rule is the one that causes the problem - epa tampering rules say that we cannot modify the engine, exhaust, intake, or fuel unless we are using epa approved components. 10k per violation per day is what is written... ewwww
its a federal law and is in effect in every state of the us. however the feds cant enforce it everywhere against everybody due to time and forces constraints - so what they do do is enforce against the mfg. hd has consistently sold products that violate the epa tampering statute. so the epa is pushing back - one of the ways is that hd cant warranty a racing motorcycle. if it has any race only parts on it its a legaly track bike for racing not a street bike. so no warranty.
the states all have laws that follow this regulation and all have a statement that race bikes cannot be titled, licensed, or registered for use on public roads.
where the difference comes is in enforcement - some states and some citys actually enforce the federal law as written. any jurisdiction can in fact, at will, without notice fine, pass on to epa for enforcement, harras, or confiscate said race bike when its caught on the street.
in practice almost nobody does - they have however written out dealer closing fines, especially in california.
there is as i see it no long term fix for any of this. the exemptions about building one non compliant bike for your own use in your lifetime are not very useful. all in all i think that those who really want power are going to have to get a vrod and the rest are going to have to either avoid driving where the cops really will enforce the law or just leave it stock.
of course, if you find a actual original panhead or early shovel frame & with a title - you can do anything you want, no restrictions.
just the way it is im afraid
