Today, I pulled the front shocks off, cleaned them, drained what little hydraulic fluid was still there and removed the seals. It is very surprising at how dark the fluid was. Most likely this is from the steel piston rubbing on the Aluminum cylinder.
Simply from this amount of contamination in so few miles, it seems like we should be adding a shock oil change to our Chinese GY6 scooter maintenance schedules.
The seals are sized 30mm x 42mm x 10.5mm. These are the same seals as used in the Honda CR80 bike. The Honda OEM part # is 91255-169-003.
Ordered new seals, made in Japan. Should be here in a few days. Then reassemble, cycle the shocks a few times, drain and refill until fluid is clear.
On a side note, someone wants to sell me a 2008 Machoman 260cc made by Roketa. It supposedly has a Linhai engine and generates 19.2bhp vs the Helix @ 17.0bhp. Can anyone confirm or deny these specs for basically an engine that is only 10cc larger? Just seems like a huge difference for such a small size change.
