Niken GT 2019, questions about some issues with condensation and bikes sitting for awhile, need some advice on what to check:

[norsie]

I got a 2019 Niken GT but it's oil has been sitting for 1+ years. It has nearly 4k miles. I purchased this engine flush but I'm not sure if this is appropriate given the circumstances(it is compatible with a wet clutch system).

The main thing I noticed was condensation coming from the exhaust on start ... anything anyone can suggest to me doing going forward?
What i'm doing so far: 

• Changing Oil + Filter
• Changing Coolant

Just drain the oil and change the filter "coolant is fine", and condensation is normal on start up and running.......just like your car does.  Hopefully the gas had some stabilizer in it and tank was near full, otherwise a chance for rust in the tank, but if it runs.......that's a good sign.

Yep I would've just changed the oil without bothering with 'flush' (which seems to be made of the purest refined snake oil)

No need to change coolant (usually recommended after 2 years on a regularly ridden bike)

FYI Niken has an aluminum fuel tank

NEVER put any sort of "mouse milk" into motorcycle engine oil.

Just change the oil and go from there.
