Let me introduce me
I'm the third owner of a 1984, GL 1200, low mileage; only 53000 miles from the begining.
I'm sure of miles, I got the papers with the complete story from 1984.
Sold new in Switzerland this model named GL 1200 interstate,(frameSC144 made in USA ,Engine SC14E 2424087 made in japan, both Californian numbers ??
perhaps bikes sold in Switzerland were Californian model, but no secondary air supply system and evaporation control system on it )
in 2003 the bike crossed the Swiss/French border to be bought by a scotish citizen living in France, I bought it in june 2017 to this gentleman.
Wonderfull shape, I just had to change cylinder head badly damaged. goldwings disease ??(photo) + timing belt, adjustments and synchro, the bike had not run for 4 years
The parts being hard to find here, I bought two US heads + a reed case and tubes ,( tks ebay) and I mounted a secondary air supply system on it. ( system that was not mounted initially )
It's strange because this bike has Californian matching numbers but nothing that characterizes these models.
any information regarding the cylinder heads and numbers subjects would be welcome
Warm regards and All the best !!!
