'87 LT250R Help
I recently inherited an '87 LT250R from my father, but theres a problem. 10 years or so ago we were in Glamis and my dad was riding the 250. I was very young at the time and was constantly getting stuck on my little 80. My dad spent more time off his bike digging me out than he did riding around. The last time he got off and left the bike at an idle it stalled. When I try to kick start it, it wont budge. I understand that it is seized, however I am looking for a more experienced opinion on what exactly is wrong before I start tearing it apart. Could it be that its just the rings or a more serious problem?
I am an active duty Marine and am dedicated to fixing this bike in my off time. I just ordered my Clymer repair manual and I will do whatever it takes to fix it, I would just like to know a little more about what I'm getting into before I start. Any help is greatly appreciated. Thank you and Semper Fi!

Welcome to the forums and thank you for your service to the good ol USA!
I suspect that you'll need a new piston kit.
Once apart you'll need to figure out which motor you have ie: F/G, H, J/K/L/M/N. And see if there is cylinder damage.
That cylinder may be nikasiled (you don't bore nikasiled cylinders).
You'll be able to figure out what piston you'll need then.
Maybe ask here too.

Hope that helps.

Thank you very much! I'm new to this whole thing so I apologize for my lack of knowledge but how then do I know what engine I have? Also, do you have any recommendations as to what else I should replace and repair seeing as its been sitting neglected for so long?

If it is a true '87, then it should be the H motor, which can be a good thing. Verify by cross referencing the vin to find the model year assuming it is the original motor.
The other things I would check are all the bearings and bushings. Be prepared to buy new, although if it was primarily a sand machine they may be OK. Replace all fluids, service the air filter and replace the spark plug. If the carb had gas in it that will need a good cleaning as well.
