The intake is a stock air box with a very old though clean air filter. You are correct about it being junk basically. Been trying to keep the old parts around until I figure out what needs to be replaced the most. I may hold off on the spark plug caps and what not for now.
The exhaust is a 4 in 2.
No idea about the jets, a friend rebuilt the carbs but must not have done the job that he said. Knew I was taking a chance in trusting some one elses work but figured it was worth a go.
The bike was given to me by a friend of my dads and a shooting buddy. So I do know him fairly well and see him about every time I go home and make it to the range. He had too many bikes and just gave this one to me. As far as I can tell it has not been ridden in 26 years. The 1st owner was a friend of his and I have met him actually. He bought it new in 1983 if memory serves me, can look it up later. He drove it until 1986, or that is when the plate is dated and the most current registration. He then parked it to work on a house he was building, it sat for over a year. He then started it and drove it to his new house. When he got home he noticed it was smoking and lifted the seat and saw the wiring was burnt pretty good. He then parked it and didn't do a thing with it until he gave it to my friend. That friend worked on it a bit, his boy worked on a bit, and then his neighbor worked on it a bit more (neighbor rebuilt the carbs). No one ever got it running. I got it in January or so and started working on it. Got it running a couple months ago and haven't taken it for a spin yet. It needs a regulator before I can unfortunately, I broke it being stupid. I have been trying to fix a few things at a time because never have a lot of money. But it may be close to ready to ride, going to fix this carb issue by pulling the carbs and looking at the jets and all the settings currently. Don't have a dial caliper to bench sync it so going to grab one from the lab on monday.
Now you asked about engineering. Yes I plan on being an engineer, bout done. Only one more year and I graduate in May. I am going for Mechanical Engineering Technology at Purdue. It is not full blown engineering, but it is more hands on. We are supposed to be engineering practioneers and designers rather than just designers. In other words what we design is supposed to work without the guys on the shop floor redesigning it so that it does.
I got into bikes to work with my hands and learn more about engines for whatever I do in the future. This one needs more work than most of the ones I have worked on but I do know a decent amount about newerish
dirt bikes. I have a 2001 DRZ400 that I wired to be street legal and had several older ones in the past few years that I have worked on a lot. Just never had an electric start bike that was meant for the road. Lots of electronics that my other bikes didn't have and a lot more carbs. One carb was always awful to get in and out of the bike so can't imagine 4. But I have experience working on some carbs. So while I may be only 22 I do know a little about what I am doing, just not a lot.
Oh an I work at a machine shop on campus so I can get a lot of the basic materials for some small upgrades there and even machine some of them. Certainly if I provide the materials and write the code to cut them. Our stuff doesn't use 3D modeling to cut up, still have to write NC code.
Now that should be enough back story on the bike and my abilities and Purdue. I will tear into those carbs after I finish my homework tonight if I can. School first, bike second... though not always easy to stick with that.
