Hello all! Just purchased my first bike last weekend. I am now the proud owner of a 1980 Honda cb750f Super Sport. Took my MSF course this past weekend and am really anxious to get out there and ride.

I purchased the bike knowing it had some electrical issues: a turn signal bulb was burnt out; the bike's battery would drain rapidly; etc.. I work in the A/V industry and have experience troubleshooting and repairing electronics, so I wasn't too intimidated.  

Also, the bike runs, but it takes a while to start up and I feel like the choke has to be used a little longer than it should. Once it is running, I noticed that the engine runs a little rough and makes a popping noise as well (not quite a backfire). He said that the carbs and plugs had been cleaned recently and they might just need synced.

What I have done so far:
-Some basic electrical troubleshooting. I found that the wiring for turn signals (aftermarket w/ running lights) was all messed up, which explains the burnt bulb. I bought new single-filament signals off ebay and will replace them this weekend. I also found that one or two of the fuses were bad, so I replaced all of them with shiny new ones.
-Purchased new NGK DR8EIX Iridium plugs (will also install this weekend)
-Bought a can of Seafoam to run through the system (tips appreciated with this)
-Got some carb cleaner because I'm guessing I will need to clean out the carbs or at least the jets. I don't necessarily trust the seller on this point...

He said the oil had not been changed this season, but the bike was not used much. I would feel better changing this out as well. I found this thread recommending Shell Rotella T6. I live in Chicago which gets hot in the summer and way too cold in the winter (the bike will be stored in a non-heated garage). Would the T6 work well? I haven't been able to find the filter I need either in my manual or the shop manual on this site.

By the way, I was really excited to find this forum and have already been well-educated as a result!
I attached a couple pictures of the bike that were from the previous owner. I will be sure to put more up when I work on it this weekend.

Oh yeah, and I purchased the bike for $750..
So I think the work I do will be well-worth it (I also really enjoy my little projects).
