I am deciding on getting a degree in ME, but if I’m being honest I didn’t do very good in school. A good portion of that was due to circumstance and my own indolence. Now that I’m out of school I have time to learn some subjects at my own pace and want to build some foundational competency in the major subjects needed for the degree. So far I’ve been re-learning math starting from pre algebra. Now is physics and chem. I’m after the basics on those what direction should I be heading in? I know thermodynamics and tolerance will be necessary. Anything else I should build some foundation on before tossing myself into what is very well one of the hardest degrees to get?

My cbr900 isn’t firing up, sprayed starting fluid in the ports and heard some bustion’ but no start. What’s the next step in diagnosis? Project from some bloke who said one of the wires caught and started smoking. He very much tried to rig it up horribly and I’m sure that’s part of the problem but want some insight and input on the next steps to repair, wanna ride this summer!! Injectors bad? Bad fuel pump? There are no dash lights so I know the bike isn’t going to blow
