Chuckpen posted to my introduction thread and seems to be in the exact same place so hopefully he'll hop in here as well.
Here's the dummies thread:
http://forums.sohc4.net/index.php?topic=29364.0Quick story: I'd decided I wanted a 750 about 6 months ago and got serious about 2 months ago. Looked at or tried to contact 6 or 7 over the course of that time (Craigslist seller's are weird birds it seems) and either ended up looking at machines that were overpriced and non-running basket-cases (that's right non-running 76 CB750 rustbucket for a grand, I'm talking about you) or couldn't get the sellers to even reply.
So one RSS feed at work and an understanding boss that let me split at 1 in the afternoon on a Thursday and I had my bike. Picked it up July 4th.
Seems it will need just about everything as the front caliper is seized, the heads leak, tires and chain are ten years old (out of registration since 1998), clutch is adjusted all the way out and some random electrical weirdness that's hopefully just bulbs (yeah, right).
Pics from the day I picked it up - CB750K-5, $500, 27,000 Miles, runs strong:
So far I've pulled and rebuilt the carbs and just got the engine out and heads off of it this weekend. Far simpler than anticipated and really only required patience. Lots and lots of patience
My intention is for this to be a daily rider so reliability and safety are first concerns.
As for cost in parts I'll total that up when it's done and put a number on it. Right now I don't want to think about it too much
Like I said the tear-down so far has been cake-like. Ran into stuck bolts. Zapped em with penetrating oil and walked away. My inclination as a teenager was to just apply more force and it scarred me mechanically for life (broken head studs, rounded nuts etc.)
Everything looks really nice internally. Oil was black as could be but there was almost nothing in the pan or on the oil-pump screen. Just a few small unidentifiable black bits (rubber?) and very small metal shavings. Should have taken a pic while I had a chance.
There's a ton of carbon build up but the cam chain is nice and tight (using the pull at the top of the cam sprocket method) and the main chain roller(?) visible in the case with the oil pan off looks pretty pristine (again didn't grab a pic).
So, the questions:
Cam chain roller. Seems a little chunky. Does this need to be replaced?
Best way to clean the heads and should I bother cleaning up the pistons?
The pistons themselves seem free of wear and the jugs look good as well. Best way to measure? Should I replace the rings?
Currently I can only work on it over the weekends. I've coated a few shop towels in WD40 and shoved them in the head. Is that sufficient to stave of rust? Will it rust? Is there a better way to do it when it'll have to sit for 5 days?
Many thanks to all you guys,
Iggy
