Sweet thanks for all of the advice I got the engine out. NOW I've run into a even bigger problem. I started cleaning out my crank case, the crank was moving perfectly fine and then all of the sudden it wouldn't budge. I think there is some small pieces of metal between the two. What is the easiest way to get the crank to move again other than splitting the engine. If I have to split the engine how hard is that to do? I contacted a mechanic in my area and he told me that I could do it myself even without a engine splitter.
First, don't force it. Didn't mention if cyl. is still on or any clutch side gears. Try gently turning crank opposite direction you were going. IF it moves, only turn it a hair. Turn it upside down and shake it, see if something falls out.
If it's a small screw, could be from reed valves. If schrapnel, you got bigger problems.
Tho cases can be split without a puller, I wouldn't suggest it. I use a harmonic balancer puller from Harbor freight.
If yours has the reed valves in the case, replace while apart.
Update: I found a really good mechanic out of Appleton, Wisconsin super cheap! Cylinder work $150 lower end $250 before parts. The guy knows EXACTLY what he is doing. He's been racing his entire life and is also a pit crew chief for a race team in the Motoamerica Superbike racing world. I'm glad I took it in to him instead of trying to figure all of this out on my own. I need a new cluth, gear fork #3 and new bearings. He's honing and replating my cylinder, putting in a Wossner piston and replacing everything else that needs to be done. Including welding my case which was broke from a previous owner who decided to use silicone. Granted it wasn't a spot that it wouldn't harm the working of the engine at all. I am also doing some painting on my quad, keeping the frame the original color. The A arms and anything else metal/aluminum on it I am painting a metallic silver. I repainted my front shock springs but don't have a spring puller so the shock and spring are now yellow. As soon as I get it all done and the engine back I will post a cpl of pics. Once again Thanks for all the help!
I noticed when I had the bike in 1st gear there was a clinking sound so I retired the bike pulled the covers off and I noticed some scoring on the pressure plate and the clutch cover. I took the bolts and the springs out to remove the pressure plate and they all took some force to break free...
So maybe I'm just stupid but I cant seem to figure out what's going on with my 1988 lt250r. It randomly started fouling plugs and running like crap. I swapped the plug and got a hotter coil and rebuilt the carburetor. I rode it around and it felt brand new, it ripped the front end up in almost...
Just bought a new water pump seal and it doesn’t fit in the clutch cover, the diameter it too large for the spot it’s suppose to fit, are there different sized seals for different lt250r? I have an 85 lt250r, where can I get the right seal ?? !!
