I recently purchased a 1989 GL 1500. (when I bought my bike, it only had 11,000 miles on it. After riding at approximately 1000 miles I began experiencing diminishing power on the top end. Research suggested I rebuild the petcock and replace the fuel filter as a starting point to correct the problem. After rebuilding the petcock and replacing the fuel filter and air filter (K & N lifetime) I am still experiencing this intermittent power interruption. It feels as if the bike is having small lasting hiccups.

Also, when I got home today, my bike had a small leak (center of the bike, apparently behind transmission)in the area of the drivers foot pegs.The leak fluid was clear in color and viscously light to the touch. Does anybody have any suggestions or insights?

This is my first post and I greatly appreciate any recommendations, thank you.

Just an idea, but have you drained the two tubes on the left side of the engine?


Also, has the liquid that leaked evaporated? Or is it still there now?

The fluid leak is likely brake fluid from the clutch slave cylinder dead center rear of engine. Check your clutch master cylinder reservoir for proper fluid level.
This is what I do

While riding yesterday, I stopped at my local Honda shop to acquire sundry items. After returning to my parked bike, I started it and noticed the clutch was not engaging properly. I asked the service dept. to check her out and they discovered the slave cylinder was kaput.

She couldn't have picked a better spot to enlighten me about clear light viscous oil that serves two purposes; brakes and clutch.

I sure appreciate the feedback and look forward to updating the forum of this journey.

Thanks again!
