Rover did the same with the K series engine head gasket issues.
Probably done more of those than any other engine back in the day.
Took a specialist to come up with the right type of gasket to sort the problem out.
Right...!
The "presumption" that after market is inherently a problem for insurers isnt valid in it's premis.
It wasnt that far back that the EU was trying to push through "Article 18" which was set to put a complete end to custom bike building.
Forks longer than "X " cms were to be banned...It was proposed that "any changes to the drive train" were to be made illegal in the sense that they could no longer be passed by the various bodies that over see safety checks ( MOT here in the UK) This meant everything though..logically. The engine cant be tuned, sprockets changed from OEM...even tyres had to be the same as the bike was supplied with to prevent any changes to wheel circumference...! Ridicule..>!
Thankfully, this was dropped but not before manufacturers, and representative bodies ( retailers, service centres et al) in Europe and the UK, had to put their reasons forward. Proposed by bureaucrats with no clue essentially. ABS and the like..( it has been made legal requirement by now) but also that manufacturers wanted the servicing of all their vehicles to maintain standards..Clearly, if they cant handle the servicing of the volume the produce, they cant really do that...
No regard for those working in the industry, servicing bikes for example. No real concept of the consequences to the structure of the industry's financial character and distribution...A total nosense. It was dropped...Phew..
Next up though.. the Super MOT. Same sh1t, different day !
And with respect the idea that govt legislation is the highest standard...
Motorcycle manufacturers have been developing their products for years between them. R&D is expensive. Integrated braking systems for example..... ABS isnt necessaril]y the best, most cost effective or appropriate system to deploy..Guess what the bureaucrats decided..Its all for nought.
Dont get too depressed....
