I've noticed that lately my transmission on my Tomos LX will be over-flowing onto the chain via the breather. However, I only fill the transmission case up to the fill-hole in the side of the motor.
I also notice that when I do fill it up to the hole, the transmission tends to slip a little and I get some vibration between shifts.
If I let the motor warm up and pull the fill-hole on level ground A LOT of transmission fluid comes out (because it's slightly expanded due to the heat).
After this, the bike runs a lot better, shifts better, and over-all rides better. Now, what's the minimal amount of oil that can be run in an A35?
I've heard of guys running about 60cc's of fluid in there and having no problems at all. I realize that the less lubrication there is, the more chance of clutch-wear and gear-wear... however the more fluid I use, the shittier the performance.
What's the happy medium?
I always use Type F transmission fluid (Advance-Auto stuff.. no fancy Mobil 1 or anything).
Thanks for the help
