Hi all, new member here.
Picked up a really cheap non-runner last night from a neighbor. He had gotten it from someone else who had rebuilt it a few years ago and it has decorated his garage since.
It is an early-90's (1992 or 93?) Suzuki LT250, but the weird part is the engine is a neon green color. I am now wondering if someone swapped the original motor out of this quad. Does anyone have experience with these that could give me a pointer as to what this could have come out of? I have heard that some Arctic Cat models had the same Suzuki motor - could that be where this came from? It is a 2WD, and has the typical chain drive/RWD system with both front and rear (rear drum) brakes. Very little rust and mostly complete, for the price I paid it isn't bad, but I am not sure how to pinpoint the engine type, and I would like to have that figured out.
Just want to make sure what I am dealing with before ordering parts. I will need a carburetor by the looks of things, and air/oil/fuel filters, plugs, etc.
Thanks in advance for any help, appreciate your experience with these quads.
Figured I ought to post a little introduction for me and my newly acquired quad. I just recently picked up a 1985 Suzuki lt250ef in pretty rough shape but a good price. Need typical things like tires, tune up, and a couple other things. Came to this forum looking for a service manual and maybe so parts. I'm looking for mostly the rear brake light assembly being as someone apparently decided to remove it at some point and bypassed the wiring. Also any pointers to typical good practices on these would be nice but I like to think I am fairly mechanically inclined. Any help is appreciated, thanks!
So this’ll be long I’ll give all the background first to see my issue skip to the ***
Hey I picked up a pit bike and a foreman for 800 the pit bike was running but the foreman was locked up. Sold the pit bike but when I took the top end off the piston I only found half a piston left. So knowing the rest of the piston was down in the crankcase I knew it had to be pulled and gone thru completely.
to pull the motor I went ahead and pulled the rear end off and unbolted the front diff to pull the drive shafts and pull the motor. Now I have the motor torn down completely and have all the parts of the piston removed. I know the rod and crankshaft is shot (heat discoloration and too much up and down play rod to crankshaft).
***so I’m wondering while I have the motor apart what should I check for? I know this motor died from heat as the oil in the head smelled like popcorn. So what should I check to make sure I fix the issue (overheating I assume) and not just the symptoms (blown up motor lol).
so put simply I don’t want to just rebuild the motor to have it overheat and repeat the process after 5mins of running
Here’s some pics
I have a gentleman that asked me to service his bayou for him. I have always wondered what oil should be used in atv engines? Pros? Cons? What weight should be used in what type of weather? Is there one kind that I could bulk buy and safely used in any quad I worked on or owned? What about performance? Engine Life? This has always been a 🤔🤔🤔 area for me with quads as far as why you would use one type of oil over another....
