[QUOTE="jdbrusch, post: 675436, member: 25926"] One of the best ways to test for a bad seal is doing a leakdown test on the motor,most bike shops can do this for you if you do not have the tools. If I had a way of posting a picture(please post a picture of one if you can) I would gladly show everyone how to make a set up for doing this,sorry I live in the middle ages,so I can only decribe what it looks like .You can make a simple one by using 2-expandable frost plugs one that fits in the exhaust port the other in the carb holder(or a plug made of plastic) The hard part is to make a adapter to pressurize the motor,2 ways of doing this, first requires a old hollowed out spark plug a T- fitting with a low pressure dial gauge and a shraider(sp) valve,the thing you pump air into to inflate tires,assembled the unit looks like a T when threaded into the spark hole, this will usually require a welder to put together.Or you can leave the plug alone and forget about the carb plug and make a plate up that you mount in place of the reed cage with again a gauge and valve,just drill and tap one hole for the gauge(pipe thread)and another hole for a bolt in valve(usually used on aluminium rims).You pressurize the motor to 8-10 psi(with a bike pump NOT A AIR COMPRESSER) and spray(with a mix of water and dish soap) the areas you think a leak is at, take the ignition cover and flywheel off and spray the seal, to test the right side you can simply spray the end of the tranny vent hose. I see you are running ATF as a tranny fluid ,one good thing about it is it smokes like a 70's Chevy Vega when it is burnt in the engine. [/QUOTE]
