My project for school this year was rebuilding a fourwheeler:huh
Yea okay here are the specifics lol.. A friend from school came to me cause he knew I was taking engine repair classes at school and wanted me to fix his quad. Well, he brought me this.. thing. From what I found out by inspection was.. it is a 1985 Suzuki LT250R Quadracer. I thought it would be fun at first but I found out shortly that these engines are crap!
So I took the engine up to school where I had all the tools and started working on that. The problem would be that, the motor had never been rebuilt in 18 years, and basically was extremely worn out, and a part was locked in the cylinder which was basically locked up, thats why he brought it to me. The crankshaft was also so worn that I could take and wiggle the connecting rod back and fourth ( no not the back and forth that its SUPPOSE to move ;) ) So I bored the cylinder, rebuilt the crank, and that was all set!
Back at home (btw the engine took about 2 weeks to do around lecture and class work) I was working on the chasis. The plastics are really crappy, broken in a ton of places, lots of patches,, and not to mention it was spray painted white with "BOOM AUDIO" sticks on it lol. Anyway, all the frame really needed was rear axle bearings. This proved to be a bigger problem then I thought, because on this model a common defect was that the brake mount clip groove is to weak and breaks easily, which it was. Before I took it apart the rear brakes were so loose on the caliper that it would have been bad if ridden anymore. Not to mention that the tires were not even tightened onto the axle !!
The fix to the carrier was a long shot, a new one costed $300, and they didnt want to pay that, so it was I would do what I could do, if that didnt work, no rear brakes. What I did was I had a kid at school weld a big bulge around where the groove was stripped, and then I took it to a machine shop where another kid machined it to the exact diameter of the other side. Sucess! Saved some big bucks there and it worked perfectly.
I just got the entire machine back together, and basically the only thing wrong with it now is the front rims are so bent that it looks mad freaky when riding it haha.
It was a cool project and I thought I would share with yall, it was a lot of fun :macho . I almost don't want to give it back to him but hey.. my job is done hehe.
