My bike continues to leak oil after 2.5 years of purchase. It is just a few drops a day but now it is like 4-6 and sometimes it stops for days or even weeks, then begins again at random. Sometimes I come from somewhere and park in the garage and next day there is a puddle, but while park in the train station all day long doesn't leak a drop!

The thing is it takes months and months for me to have to replace any oil, but it bothers me.

Can anyone tell me what to look for, and since the whole bike is bound in plexiglas, where I begin to dismantle, which panels? I know how to dismantle athough I have not been able to reach the motor which has its own cover.

Thanks for any advice!

Guys: after consulting with the honda dealer, I went ahead and bought at the auto parts a very heavy sealing oil from Lucas. I did 3/4 new heavy oil with one quart regular oil. I had to put the oil in hot water for five minutes to make it run easy and it is a mess to clean but the bike has reduce leaking by about 90%. Right now it's been parked for one week because of the heavy rains we had here and only about a spot the size of a dime is on the ground, while before there would be a mess. Hot or cold it leaked the same but the difference now is significant. I hope it continues this way.

Hello Dribanez.
A couple of thoughts on your oil issue:
1/ In my opinion, a little oil leak from the engine is not a big deal. Just keep the oil level topped up.The PC800 engine is notorious for leaking some oil.
2/ Be wary of adding too much oil thicking agent. Don't exceed 20 % of volume. The problem is that these agents can change the viscosity of the oil. If the viscosity is too high, top end damage can result. On startup, high viscosity oil can starve the cams, cam followers, and bearings. I recommend that you drain your oil, replace your filter, and start again. New filter, new 10-40 oil and 10% of Lucas sealing oil. If it leaks a bit, don't worry about it.
3/ My PC800 has 120,000 km on it. Leaks some oil. I don't care. Works great.

thank you so much. you've put my mind at rest. this weekend will remove the heavy oil and just add 10/40 without the thickening. I need to remove the oil worry from my mind.

It's just that I am kind of crazy with that. I have had many boats, power to 114', sailboat to 65' and I always kept white adult pampers under the engine well in mid air because under each engine is usually a basin for collecting oil leaks so I held them on the very top of the pan and checked it every day. It's the first thing I checked when I got aboard. My previous 12 Honda and two Yamaha never leaked. I heard that Harleys leak all the time so I'm making a mountain out of nothing :).

ok thanks!

A marine environment is a different story. I have a boat and an oil leak of any kind is a big issue. If your bike stalls, you can walk. If your boat stalls, well, you have to have damn good connections if you can walk to shore.

I had the same problem, most of the time I can smell burnt oil when I would stop at a light. I decided to find and fix the problem. What I found was two leaks, the cam seals and the two valve covers and the clutch slave seals. ImageImage

If remember correctly, the valve covers don't have a gasket. They are machined to fit. I've found that using a light coat of gasket cement seals a leak that is common with this motor.
