Hey guys my 1990 lt250r I'm pretty sure is burning my tranny fluid. The amount of spooge is rediculous. All over the Frame motor and swing arm. I'm pretty sure it's the crank seal but do you have to pull the motor out and split the cases. What do you do?
nope you can replaced the seals without pulling the motor
Is there any how to guides on this that you know of?
Not to hijack this thread, but related enough to post here rather than start a new thread:
I too have a bunch of black stuff leaking out of the exhaust area onto the frame an front of the engine. I've replaced the seals on this bike twice, one with some cheap seals and then with some higher quality winderosa seals with no real difference. I even changed out the o-rings on some of the collars, etc...
What else could be causing this is not the engine seals?
Also, to answer thread starter's last question, you can find schematics for your engine in the Clymer repair manual, or if you go to an ATV web store like
www.rockymountainatv.com and go to "OEM Parts" you can find schematics under your bike's make & model.

What pipe are you running?I have black crap below the exhaust port due to the exhaust pipe to collector connection.Its simply some spoogeleakage from the exhaust.Some of the high end pipes use O-rings on the connection to eliminate it.Or you can reaseal the slip on connection styles with orange high temp silicone but will likely still leak some.
Okay that makes sense then. I'm running an ancient FMF Gold Series pipe on the bike. As long as I'm not burning transmission oil then it's no big.
Thanks.

If your flange is removable from the main body of the pipe, you may be able to have grooves machined around the outside circumference to accept O-rings to help eliminate or at least reduce the oil blow through.
Know where I can find a machine shop in Y-town?
