Really funny, Rich. The dye says it's behind the stator...  |

I drove my scooter to work for the first time this morning. There is still a leak behind the stator!  I'm not sure if it's the seal but I assume that it is. I'm pretty certain that it's not overfull. What could cause this? |

Hey All,
I have some great news and not-so-great news...
Great news: I was able to eliminate the leak entirely at the gasket. I used the red RTV and the pre-cut gasket together as recommended and it worked great. No more leak.
Not-so-great news: Although I replaced the seal there's still a leak behind the stator. I believe it's the lower bolt that holds the stator. It seems that the oil is seeping around it. However, I can't be 100% sure. What I did, though, is remove the stator and fill the bolt hole with the red RTV. I also oiled the crankshaft and filled the area in front of the seal and around the shaft with the RTV. I put it all back together, let it cure for a few hours, and let it run for about 30 minutes with no sign of a leak anywhere. I'm hoping that the problem is solved.
The bike is in the garage for the next few days (a storm is in town until Wed.) but after that, I will do a road test and let you know how it goes.
Thanks,
Adam

Hey Guys, I stopped by the local scooter shop here in Charlotte, NC called Carolina Fun Machines. Really nice place and nice people. They had a 19.8x30x5 in stock. After getting home I popped the old one out and confirmed that it is, indeed, a 19.8x30x5. So, it looks like I have everything in order to do the installation over the weekend. I picked up some degreaser and acetone along with some 3M heavy duty scrub pads. I want to take some time and clean it up while it's torn apart and do it right. Thanks! You guys are awesome  Adam |

So, I picked up a gasket yesterday. It took a while but I was able to get the cover off and the old gasket stripped. However, there's been some new developments.
When I removed my flywheel I noticed a quarter sized puddle of oil on the lip below the stator. After shining my blacklight on it I could see a trail of oil coming from the crankshaft oil seal. The seal itself was covered in oil (it was glowing really bright under the light). A leaky shaft oil seal explains more easily how the fan could be blowing the oil around.
Now, I have a few questions regarding this and the gasket:
1. I failed to get the size of the oil seal. What should I purchase? I want to pick one up today at the local shop.
2. I was able to use a razor blade and scrape a majority of the old gasket off. However, there's still some residue in a few places. How should I clean this off? Does it matter?
3. Should I use a gasket sealer of some type?
4. Anything I'm missing?

Thanks Rich! I'll get it installed and let you know how it goes.
The most amazing thing to me, at this point, is how a leak in that location can be picked up by the tire AND the fan and flung/misted everywhere. I mean, there's oil all the way up at my gas tank and fuel pump. I guess that's why it's important to not assume you know where the leak is coming from.

Positive update! ;D I found the leak. I used InterdynamicsUV Oil Dye ( bit.ly/rftIF4) and used a black light and it was beautiful. The leak glowed so bright I couldn't miss it. Fortunately, I didn't see any other leaks at all. The only leak that I found was at the back of the crankcase. It's definitely a bad gasket because it's leaking out right along the seal. The location of the leak is circled in the image below:  I'm going to order this gasket and install it over the weekend ( bit.ly/nzDrV6) Let me know if you have any thoughts, Adam |

drjeff, right, but as far as I can tell shipping is usually around $70 or more.

Thanks for the suggestions. I'm leaning heavily toward just replacing the seals. I don't want a temporary solution. I want it fixed.
Also, I'm thinking about grabbing some UV oil dye. This looks like a great way to find the leak, IMO.
Finally, Rich, I appreciate you opinion and would absolutely do a full replacement if it was within my budget. But, $50 compared to $300+ is a big difference. I'll try the fix first.
Thanks!
- Adam

OK. Well, what I have is "Blue RTV Silicone". I imagine that would do the trick.
The issue seems to be that I can't be sure that is the only leak. Unfortunately, it only leaks when I take it down the road. Any ideas how I can't get it to reveal itself?

Cool! That's a good idea. Would silicone gasket maker work for that as well?

That's what I thought would happen.
The oil is right at the middle of the dip stick. The vent tube seems to be clear and free. I'll take it off and double check though.

Hey Guys,
Here's (hopefully) the final mystery to solve on my scoot.
As I've mentioned before, I have an oil leak and boy is it a mess! Oil is getting everywhere. It was just plain impossible to see where it was coming from so I took the suggestion to strip ever bit of plastic and degrease the entire thing. Then, I let it run for about 20 minutes and noticed an oil seepage at the bottom of the right crankcase cover, near the bottom of the filler spout. Oil was also seeping from between the right crankcase and crankcase cover in front of the back wheel, inside the wheel well.
So, I tightened the bolts on the cover and cleaned again. I ran it for a while and didn't see a leak so I hoped that it had stopped it. However, this morning I reassembled the whole thing (ugh) and within two miles had another oily mess under the engine. So, here are my questions:
1. Can oil from the right crankcase get all the way up to the front of the engine area? I imagine that the wheel turning and the airflow inside the engine area can make a big mess. It's even getting under the plastic shroud over the engine. Could the flywheel be slinging it around?
2. What do I need to know about removing the right crankcase cover?
Thanks in advance!
- Adam
