Reviving a long-idle GSF1200. Inspection, carburettor maintenance + OH, tank cleaning and coating, engine oil change, and more

Letting a motorcycle sit idle for too long really causes serious problems.
It costs money, and it’s a hassle for us to work on too—which means higher costs!

Even if you’re not riding, please start the engine at least once every two weeks or once a month.
If you can, take it around the block.

This is the condition before cleaning.

We managed to revive it like this. Coating is a last resort.
Once you coat it, you can’t machine or weld if any problems come up.

While that’s unlikely to happen, be careful—DIY coating can be risky if done carelessly.

We removed the carburetor and started preparing for the OH.

We’re grateful that intake manifolds are still supplied for the 1200 series.
But if we get complacent, they might be discontinued before we know it.

These days you can buy them online, so if you plan to keep your bike long-term, I recommend stocking up. Check the prices and part numbers for reference.

Wow, it really stinks… It’s been a while since I’ve seen a carburetor this clogged.
Of course, the extra work means additional charges!
